Besides earning money from YouTube ads, there are other ways a YouTube channel can boost your monthly income. For instance, your increased exposure on YouTube is a great way to advertise your services, and you could use it to lead subscribers to an online course or eBook. 

Many YouTubers also make extra money through affiliate marketing, merchandising, and subscription-based services like Patreon, so consider adding these to boost your expected earnings. 

Pay: As mentioned above, you must get 1,000 subscribers and 4,000 public watch hours within 12 months to join the YouTube Partner Program. YouTube also allows people with 10 million public Shorts views within 90 days and 1,000 subscribers to join this program.

While the amount you make from YouTube varies depending on your channel’s size, most estimates suggest YouTubers typically get $0.018 per view. So, to hit $180, you need to get at least 10,000 views on a video. However, these rates can vary as your channel scales and as you build more revenue streams. 

How to Get Started: You don’t need an elaborate studio or a fancy camera to start uploading on YouTube. However, engineers starting on this video-sharing platform need a clear idea of what they want their channel to focus on and what topics to record.

It helps to have a basic understanding of writing YouTube scripts and editing to make your clips as concise, informative, and professional as possible. 

If you need help producing YouTube videos, consider taking a professional YouTube course from someone like Erika Kullberg, with experience growing channels to thousands of subscribers.

14. Start a Podcast 

Podcasts are the 21st century’s version of “radio programs,” and they offer engineers another way to earn side money by sharing their expertise. So, if you’d prefer to focus on producing audio content rather than videos, podcasting may be a great alternative route versus YouTube. 

Consider starting a solo podcast or inviting guests in an interview format on your engineering-themed show. 

Typically, podcasters make money through advertisements and syndicating their shows on platforms like Spotify and Apple, but you could also generate revenue by offering exclusive paid content on sites like Patreon, selling merch, or accepting public speaking opportunities as your podcast grows. 

Even if you don’t earn a ton from podcasting directly, this is another great way to increase your visibility and attract more side gig opportunities and inquiries. 

Pay: Podcasters often measure their revenue in a metric called “cost per mile” or “cost per thousand” (CPM), which refers to the cost they charge per ad for every 1,000 impressions or downloads. 

This average rate fluctuates throughout the year, and how much you can charge advertisers depends on your channel’s size. However, HubSpot estimates the average CPM for 30-second ads hovers around $18. Data on ZipRecruiter also suggests the national average for podcast hosts is around $16 per hour. 

How to Get Started: Like starting a YouTube channel, you must clearly define your podcast’s niche and target audience before recording your first show. It’s also vital to have outlines for each podcast to avoid dead air and deliver the most value to your listeners. 

Once you’ve established the basics, purchase podcasting equipment like microphones, headsets, and recording devices to ensure you achieve a crisp, clear, and consistent sound quality. 

New podcasters must create their own RSS feed so they can submit episodes to sites like Spotify, Google Podcasts, and Apple. For those new to podcasting, consider using platforms like Fusebox to add professional details to your show with minimal effort.

How to Create a Podcast for Beginners

15. Start an Engineering Blog

All you have to do is write content about anything in your engineering sector and start publishing them. 

The more educational or informational posts you publish on your site, the greater the odds search engines will see you as an authoritative source for your engineering field.

You can monetize a blog with a number of different strategies, including affiliate links, ad networks like Google AdSense, or publish sponsored posts.

Pay: Like podcasting or posting YouTube videos, the amount you can make from blogging depends on your audience size and the quality of your content. An estimated yearly salary for bloggers is in the $50,000 range, but Glassdoor suggests this could be even higher at $80,000

While it’s possible to hit these high figures with a successful blog, most new bloggers won’t earn more than a few hundred bucks per month. For instance, ZipRecruiter suggests the average hourly rate for most bloggers is between $9 – $30 per hour

How to Get Started: Knowing the basics of using popular content management systems (e.g., WordPress), Web design, and coding languages like HTML are excellent skills to start your blogging journey. However, there are also plenty of no-code and low-code platforms like Webflow, which help users create the blog of their dreams without as much technical expertise.

It’s also helpful for new bloggers to familiarize themselves with SEO and tools like Clearscope, Semrush, or Ahrefs. Lastly, consider signing up for a professional blogging or freelance writing course to understand the basics of writing for the Web. 

16. Sell Printables on Etsy

Any engineers passionate about graphic design should consider adding Etsy printables to their passive income repertoire. In fact, if you already use a few personalized spreadsheet templates for managing your engineering work, you could earn a lot of money selling these sheets on Etsy. 

For instance, there are plenty of profitable printables on Etsy for budget tracking, meal prep, and homework planning. For those who aren’t super enthused about spreadsheets, you could also make printable cards for events, special occasions, or holidays (think Halloween, birthdays, and weddings). 

While the competition to sell printables is fierce, this is one of the most passive side hustle opportunities with a low barrier to entry. Even if you use a professional design platform like Canva Pro, it doesn’t cost much money or time to design and upload printables, and you don’t have to worry about shipping fees. As long as you check in on your Etsy store and respond to customer demands, this strategy is almost like “printing” side money! 

Pay: There are crazy stories of people making $100,000 annually in printable sales, but you probably won’t get that lucky from the start. But even if you don’t grow to become the highest-ranking store, most printables on Etsy range from $1 to around $20 per download. 

Just keep in mind Etsy charges a 6.5% transaction fee on each sale, and you have to factor in taxes to your estimated earnings.  

How to Get Started: People who get into making printables on Etsy often use sites like Canva or Adobe Illustrator to design and upload their creations. You could also use Microsoft Excel or Google Sheets to create downloadable spreadsheet printables. 

Also, when you set up your Etsy account, it’s worth reviewing what printables are trending and relevant keywords on sites like Google Analytics. If you need professional help getting started in Etsy printables, check out educational eBooks dedicated to this topic to get a headstart. 

17. Become a Proofreader 

If you’re OK with adding extra reading time into your schedule, proofreading might be a good way to earn some extra money. 

In this side hustle, you’ll review documents, eBooks, or blogs to scan for grammatical issues, typos, and other errors pre-publication. While you could proofread content in any field, look into technical topics that fit your engineering specialty for potentially higher returns. 

Proofreading may not be the most passive opportunity on this list, but it offers decent benefits if you already enjoy reading and correcting content. 

Pay: According to Indeed, the average yearly wage for a proofreader is $22.15 per hour, and Salary.com estimates the median annual income for this profession is almost $57,000.

How to Get Started: The most straightforward way to start proofreading is to look for gigs on job listing sites like Indeed, Fiverr, or FlexJobs. Upwork and ZipRecruiter also have proofreading opportunities worth checking out. 

If you’re still struggling to find proofreading work on freelancer sites, consider registering for a professional freelance proofreader course to learn the basics of this side hustle.

Pay: The pay for part-time tutoring positions ranges depending on your reputation, the subject you’re teaching, and your state’s average pay rate. However, data on ZipRecruiter shows the average price for part-time tutors hovers in the $22 per hour range

How to Get Started: Before applying for part-time tutor positions, you may need to obtain accreditations from groups like the National Tutoring Association. Be sure to figure out if there are any requirements you need to become a part-time tutor before applying for jobs.

If you don’t have a local school or tutoring agency in mind, start your search on websites like Indeed, LinkedIn, or ZipRecruiter to find opportunities. 

22. Become a Substitute Teacher 

Unlike tutoring or designing courses, substitute teachers don’t have to develop original lesson plans for their students. Instead, engineers who take on this role follow the templates left by the original teacher to ensure the class doesn’t fall behind. 

Substitute teachers may also need to assign or collect homework and help students with questions about their coursework. While this isn’t a “passive” opportunity, it’s a good way for engineers curious about education to get their feet wet. 

After working as a substitute teacher for a few months, engineers typically know whether they want to pursue other side hustles like creating online courses or applying to be a tutor. 

Pay: The average salary for substitute teachers fluctuates by state, but ZipRecruiter estimates the average range is between $14 and $22 per hour

How to Get Started: The simplest way to start looking for substitute teacher positions is to search local school districts online and look for openings on official websites. 

If you can’t find any info through Google, consider looking on sites like Indeed, ZipRecruiter, or LinkedIn to see if there are availabilities for subs in your target area. Like tutoring, please be sure if there are any additional requirements to become a sub in your state.

23. Become a Handyperson

Do you love DIY projects and home improvement? If so, consider offering general handyperson services for residential and commercial properties. You could also tailor your offerings for specific areas of expertise, including electrical work, plumbing, or even HVAC. 

The more general skills you know about repairing, replacing, or renovating, the better equipped you are to offer high-quality handy services to clients in your area. Just double-check you have the educational experience and licenses to offer handyperson services in your state legally. 

Pay: Indeed and ZipRecruiter estimate handyperson salaries average in the $20 per hour range, but this could fluctuate depending on the projects you’re involved with. As you gain more experience and build a portfolio, you’ll have an easier time attracting a wider variety of higher-paying side hustles. 

How to Get Started: If you’re just starting as a handyperson, you might want to consider working with an accredited general contractor to get on-the-job experience and build up your resume. However, you could start offering handy services immediately on sites like Handy.com, Thumbtack, or Angi.

24. Provide Home Inspection Services 

Home inspectors are responsible for scanning every nook and cranny of a property for potential concerns and presenting them to realtors, owners, and prospective homebuyers. 

In this role, you’ll be responsible for spotting visible defects inside and outside of a house, including electrical panels, attics, and sink cabinets. 

Since engineers already have an eye for structural details, it’s usually relatively easy to recognize and document a home’s flaws in an inspection report. However, keep in mind you’ll need training and accreditations to offer this service professionally. 

Typically, you need to pass a course with a state-approved agency and the American Society of Home Inspectors (ASHI) before making money from this side hustle. 

Pay: Information from ZipRecruiter suggests the average salary for home inspectors is around $40 per hour, but these rates vary depending on where you live. For instance, Bankrate reported the average cost per home inspection is usually between $199 and $500 in the United States. 

How to Get Started: The best place to start looking into accreditations for this side gig is on the ASHI’s webpage and your state’s employment website. As you gain your inspector accreditations, be sure to build a network with teachers and home inspector services to make finding opportunities easier after your graduation. 

You could also use employment sites like Indeed and ZipRecruiter to get started finding opportunities in your area. 

25. Flip Furniture 

Crafty carpenters reading this post may want to consider buying and beautifying furniture for the resale market. To make money from this side hustle, find cheap furniture online, on consignment, or in yard sales, and give your purchases some TLC before listing them again at a higher price. 

While you could resell your furniture in person at flea markets, many people who get into this side hustle rely on sites like Facebook Marketplace and Craigslist to find interested buyers. 

Pay: There’s no “standard” rate for how much to expect from flipping furniture, but you could make a few extra hundred bucks monthly with solid products. 

How much you make in this side hustle depends on the cost (including time) you put into remodeling your furniture, how much you relist it for, and your success rate attracting buyers at your preferred price. Be sure to keep a tab on your expenses to determine the perfect price for each piece of furniture, depending on your profit goals. 

How to Get Started: Aside from furniture, all you need to start this side hustle is equipment to spruce up your piece and a venue to showcase your offering. If you want to be conservative entering this side hustle, search around your area or on sites like the Facebook Marketplace for free furniture so you don’t have to put any money down to jump into this hobby. 

After you’ve cleaned and fixed your cabinets, chairs, or tables, take a few high-quality photos and list them on sites like Craigslist or Facebook Marketplace at your preferred price. 

If you need more expert guidance on furniture flipping, consider taking a flipper-focused course like Flipper University to learn the strategies pros use to succeed in this field. It also helps to become familiar with how Facebook Marketplace and Craigslist work.

26. Fix Stuff

If you fancy yourself a “fixer-upper,” why not offer repair services for some side money? Whether your forte is carpentry, electrical work, or plumbing, there are always plenty of problems you could earn quick cash to fix. And don’t forget to advertise any non-house-related services you’re familiar with, like car or motorcycle repair. 

Similar to working as a handyperson, please figure out if there are any license requirements for your areas of specialty just to be on the safe side. 

Pay: Data from the US Bureau of Labor Statistics found the average yearly salary for workers in the “General Maintenance and Repair” field is about $43,000 per year (or about $20 per hour). Of course, your hourly rate will vary depending on your experience and the specialized skills you offer. 

How to Get Started: You don’t always need specific accreditations to start offering “fixer-upper” services but double-check if there are any state-required licenses for your specialty in your state. 

Handyperson or DIY-related sites like TaskRabbit, Handy.com, and Thumbtack are great places to put up a profile and start attracting business to fix stuff in your area.

27. Sell Your Crafts

Many engineering-related fields like woodworking and metalworking naturally lend themselves to crafty endeavors. So, if you’re an engineer with an aesthetic flair, you may want to use your skills to create crafty items and sell them at local fairs or online. 

Sites like Etsy make it easier than ever to start a side hustle centered around artistic items, so there’s no need to take the “starving artist” route! Take a peek at what’s hot using Etsy’s analytics and Google Trends to tailor your arts and crafts to the latest fads. 

Pay: The US Bureau of Labor Statistics estimates craft artists make a median salary of $18 per hour, and ZipRecruiter also shows the average salary for arts & crafts vendors is in the $19 per hour range. However, depending on your online reputation and the market demand for your items, you could scale up this side business to make a few hundred bucks monthly.

How to Get Started: Sites like Etsy and the Facebook Marketplace are obvious choices to monetize your arts and crafts, but you don’t have to sell exclusively online. Consider researching studios or local arts & crafts fairs in your area and setting up a booth to display and sell your items. 

At local events, you can ask your customers if they have any personalization requests, which may bump up your sales. 


Gig Economy Side Hustles For Engineers 

Although many engineers are passionate about their work, there are times when we all want to tune out our professional lives. So, if you want a way to make side money that doesn’t involve engineering, check out these hot gig work opportunities. 

28. Become a Rideshare Driver

Rideshare drivers have become one of the most iconic side hustles in the gig economy. If you don’t mind driving others around in your car, you can earn some spare change in your free time in this “independent contractor” position. 

Whether you add a few extra stops on your ride home or before running errands, there are many times to fit a rideshare session into your schedule. While rideshare driving may not be the most lucrative opportunity when you deduct expenses like gas, it’s a legitimate way to earn pocket change for everyday expenses.  

Pay: Data from ZipRecruiter shows Uber drivers earn anywhere between $12 – $17 per hour, depending on their state. However, info on Indeed suggests the average rate for Uber drivers may be slightly higher at an average of $19 per hour

Of course, as you gain higher reviews on your chosen rideshare platform, you’re more likely to find passengers willing to pay a little extra for a pleasant experience. Oh yeah, and tips help a lot! 

How to Get Started: As long as you have a valid driver’s license and meet your app’s minimum age requirements (18 for Uber; 21 or 25 for Lyft, depending on the state), you can download a rideshare app and apply to work as an independent contractor. 

Once your company approves your application, log into your mobile app and wait for customers to book a ride. For the best odds of getting 5-star ratings, have plenty of helpful tools like a GPS and cleaning equipment (including a few vomit bags) on hand for a fantastic guest experience. 

29. Become A Delivery Driver 

Delivery driving gigs are similar to rideshare positions, except you’ll have food in your car rather than a group of friends! As more people expect rapid at-home delivery services, some of the biggest eCommerce brands, grocery stores, and restaurants are looking for gig contractors to shuttle stuff around towns and cities. 

So, if you’d prefer to transport items in your area, consider signing up for a delivery driver platform to earn some extra weekly cash. 

Pay: Delivery drivers typically earn the same average hourly rate rideshare drivers get for their services. In fact, both Indeed and ZipRecruiter estimate the average income for a food delivery driver is in the $18 – $19 range.  

How to Get Started: Similar to setting up a rideshare account, you can get started as a delivery driver if you meet a company’s minimum age requirement and have a car and a valid driver’s license. 

Uber Eats, DoorDash, and Grubhub are a few of the most popular apps in the food delivery sector, while Instacart is a hot option for grocery delivery. Amazon Flex also has gigs for people who want to ship eCommerce boxes to homes.

30. Rent Out Unused Space

When people think about renting out a part of their home, they typically envision signing up for a short-term rental app like Airbnb. While it’s possible to earn passive income from renting rooms to travelers, you don’t need to go that far to make passive income. 

For instance, if you have some spare space in your garage, you can find someone to pay you to park their car in your place. Sites like Neighbor.com let people rent out small and seemingly insignificant spaces to people who need a storage option. 

Just keep in mind you need to give your client unabridged access to whatever space you rent out. Always carefully review your legal agreements and the Terms and conditions on your chosen platform before deciding whether this income opportunity suits your lifestyle and privacy preferences. 

Pay: Since the “space rental” concept is relatively new, there aren’t many metrics on how much this side hustle pays. However, Neighbor.com estimates average prices for RV storage offerings are around $50 to $150 per month

So, engineers testing this side hustle should expect a max of a few extra hundred bucks monthly. Of course, these rates vary depending on what and how much you’re renting out. 

How to Get Started: Currently, Neighbor is the leader in the “rent space” category, so you should start by exploring this site to jump into this side hustle. However, other specialized brands in this “space” are constantly popping up. 

For instance, Swimply offers a way to monetize your cool blue pool when it’s not in use. The site Store At My House also helps you make money by renting space to others who want to, well, “store stuff.”

31. Rent Out Your Car 

On apps like Turo and Getaround, you can list your vehicle and become a mini car rental service. So, as long as you don’t mind others driving your car, you can earn money every time people book your car for vacations or business trips. 

While this is a fantastic way to earn passive income on a car you’re not using, carefully review the insurance requirements on the platforms you’re thinking about joining. Sometimes, you might need to change your coverage to account for strangers hopping in your car’s driver’s seat.

Although the customers on apps like Turo go through background checks, there’ll always be potential legal hassles associated with handing over your keys. 

Pay: The best way to estimate how much you can earn on a car rental site is to type in your specific info on a tool like the Turo Calculator. On this calculator, you’ll see average yearly estimates for renting through Turo depending on where you’re located and the make and model of your vehicle. 

Understandably, you’re more likely to make thousands per month in a city like NYC versus low-density rural locations. Also, more premier cars naturally fetch higher prices from customers who want a more luxurious experience. 

How to Get Started: First, you have to choose a car you’re willing to rent and figure out the dates you’re free to put it on the market. Next, choose an app offering “car-share” services and review their insurance policies. 

Today, a few of the most popular car-share apps include Turo and Getaround. Once you’ve completed a successful application, post pictures of your car, note any blackout dates, and respond to requests. If someone books your car, bring it to a designated destination, hand off your keys, and pick it up again once your customer’s trip ends. 

32. Rent Out Your Home

Home rentals have become a hot travel trend thanks to the popularity of apps like Airbnb. Although traditional hotels aren’t going away anytime soon, homestay platforms give engineers the opportunity to earn side money if they have a property they’re not currently using. 

There are also techniques like “Airbnb arbitrage,” where people upcharge the rent on their apartments to people looking for short-term stays (be sure to check with a landlord if you’re using this method!). Just remember, if you’re getting into the Airbnb game, you’ll need to deal with cleaning your home in between stays and potential issues with tenants. 

Pay: Some reports suggest Airbnb hosts can make an average of about $950 per month, but this depends on how attractive your area is and the size and quality of your property.

ZipRecruiter currently estimates Airbnb hosts make an average of $18 per hour from this side gig, but you should research current rates in your city and use tools like an online Airbnb Calculator to get a more accurate picture of your profit potential. 

How to Get Started: Once you’ve decided what house you’re going to list online, be sure it’s well-furnished and clean before taking pictures and putting it up for rent. Although Airbnb gets most of the attention in the homestay space, other sites like Vrbo and FlipKey provide ways to enter this market. 

There are also specialty sites like RVshare if you have an RV you’re willing to loan to someone for their vacation. 


Final Thoughts 

Although many engineering professions have high earnings potential, working up to a professional status takes a long time. As engineers refine their skills and progress on their career path, it helps to have some extra cash from side hustles to keep financial stress at bay. 

Whether you need money for groceries, gas, or student debt, adding a side gig can help you achieve your goals. Thankfully, with the rise of gig work and “work-from-home,” it’s getting easier to find various opportunities to earn extra cash from doing things you love — or at least doing something you don’t mind too much! 

Consider trying a few gig work opportunities to find what works best for your preferences and work style.
