A little extra cash can help your monthly budget. But what are the best ways to make more money? Read on for some great ideas and tips to get you started.

Nearly 40% of Americans earn $8,000 a year with "side hustles," according to a 2018 Bankrate survey.

Whether you're trying to pay off bills or saving toward a long-term goal, here's a list of ways to earn an extra $100 a month.

Give Your Electronics New Life

Why not tackle your electronic clutter to make a few bucks? If your phone, computer, or other hardware has seen better days, consider selling it using these sites.

For these options, your take is entirely dependent on the item you're listing. For example, an iPhone 8 Plus in excellent condition might earn $350 - $370 on Gazelle and BuyBackWorld, respectively, and as much as $700 on Craigslist.

Selling a big-ticket item like a phone, laptop, or game console is your best bet to earn $100.


Gazelle: This is a great option for selling Apple products, phones, and laptops.

  • You'll need to provide accurate information about your item to receive a quote. Describe the physical state, functionality, and, if necessary, hard drive, RAM, and optical drive.

  • Payment is offered via check, PayPal, or Amazon card. Depending on the method of payment, you will receive money in 3 - 10 business days.

  • The site provides a free shipping label via email or a physical shipping kit via USPS.


BuyBackWorld: This website buys over 30,000 different types of items, including cameras and GPS equipment.

  • Fill out a brief questionnaire to receive a quote for your item. If you can't find your item on the site, you can request a custom quote.

  • Payment is offered via PayPal or check, which can take 3 - 10 business days to receive. They also offer a QuickPay option for faster payment.

  • You will receive a free shipping label via email to mail your item to BuyBackWorld.

Make sure to include your cables and chargers when listing your items.


Craigslist: The site is geared toward selling to local buyers. It's ideal for those who want to avoid shipping hassles.

  • You create your own listing, which means more control over pricing. You may also earn more for your time.

  • Use the website-provided email address or use a secondary phone number service such as Google Voice to protect your personal information and ensure your safety.

Resell Your Textbooks

Buying used textbooks can set you back hundreds of dollars. So there's no reason to leave them collecting dust once class ends.

Consider selling your books online with user-friendly apps and websites.

Most used books will earn you $5 - $50 on the below resale sites, depending on the subject and demand. To have the best chances of hitting $100, wait until the end of the school year to sell your books.

Expect to wait 1 - 2 weeks after shipping to get paid.


BookScouter: A textbook buyback comparison tool that compares prices from over 40 websites.

  • Find the best buyback price for your book by entering the book's ISBN into BookScouter's search engine.

  • BookScouter's mobile app will quickly and easily compare book buyback prices.

  • Sellers can refer to BookScouter's rating system to get more information about user experiences with various booksellers.

Valore Books

ValoreBooks.com: A highly-reviewed option for selling books in bulk.

  • Books must meet buyback standards: no excessive damage, highlighting, writing, and no missing CD/DVD accessories.

  • ValoreBooks requires the ISBN for a quote. The site will match any higher price you find on a different website within a week after you sell the book.

  • Payment is offered via check or PayPal. Checks will arrive within 7 - 14 business days. PayPal posts to your account within 2 - 7 business days.


Chegg: This book buy-back site has been in business for 14 years.

  • Books must meet buyback standards: no excessive damage, missing or torn pages, or burns and rips.

  • Chegg will not buy back international or teacher's edition books, which are usually denoted by marks on the spine, cover, or first few pages of the book.

  • You can receive payment via check (10 - 15 business days after the book is received), PayPal (3 business days after the book is received), or via Chegg credit for future textbook orders

Don't sell your textbooks back to the university bookstore. They'll typically offer less than 30% of what you paid.

  • You are responsible for marketing your content and are able to set your own pricing.

  • Payments are earned monthly and are deposited into your PayPal account.

What can you expect to earn?
Similar to Skillshare, you can your earnings depend so much on just how much you charge, but also how you market what you have to offer.

Amazon Mechanical Turk

Amazon Mechanical Turk: Complete microtasks from the comfort of your home.

Put Your Purchases to Work

You can earn and save money from regular everyday purchases. Check out a few options below.


Acorns: Round your credit or debit purchases to the nearest dollar and watch your investments grow.

  • Acorns rounds up your debit and credit card purchases to the nearest dollar and collects that "loose change" in an account.

  • Once your "Round-Ups" top $5, Acorns transfers it to an investment portfolio based on your personal information.

  • Depending on the program you choose, there will be a monthly fee of $3 - $9.

What can you expect to save?
You might need 200+ transactions a month to reach $100 using acorns.

For a complete rundown, check out our Acorns Review.


Honey: Install this browser extension and find coupon codes for 30K+ stores online.

  • Honey automatically checks for available coupon codes for online stores where you shop, including e-commerce giants like Amazon.

  • You can enroll in the Honey Gold rewards program to earn a percentage back from purchases on 4K+ participating sites.

  • Use Honey's price history tool on Amazon and avoid overspending on frequently discounted items.

What can you expect to save?
Because it entirely depends on your shopping habits, the more time you put into historical sales trends, the more likely you are to save big.


Paribus: Find a lower price for something you already bought? Paribus will get you a refund.

  • The Paribus app identifies recent, refundable purchases based on shipping and order confirmation emails found in your inbox.

  • The app will file a claim with retailers to request a refund on items whose prices have dropped by at least $3. Paribus then issues 100% of the price difference to you.

  • Once a retailer confirms a price adjustment, your refund is typically issued within 3 - 7 business days to the account used to make the original purchase.

What can you expect to save?
Similar to Honey, Paribus entirely depends on how much you spend, and how much you're willing to put into price research.

Go the Rideshare Route

Rideshare apps are popular for a reason: You can earn extra cash with own car on your own schedule. If you're thinking of joining the fleet, take a look at these options.


Uber: This rideshare industry pioneer boasts a network of over 3 million drivers worldwide.

  • Meet Uber's driver requirements: at least 21 years old, in-state auto insurance, driver's license, and plates with current registration, plus a 4-door vehicle no more than 10 years old.

  • Uber charges their drivers a 25% fee on all fares. Payments are initiated weekly on Mondays and reflected in driver bank accounts by Thursday.

  • Uber offers car rental programs for aspiring drivers without their own car. All drivers are covered with Uber's $1M insurance policy while en route.

What can you expect to earn?
Average earnings for Uber drivers will range from $11 - $15 per hour.


Lyft: Another rideshare industry giant, Lyft offers competitive pay for drivers.

  • Lyft has driver requirements very similar to Uber, though their car requirements will vary from city to city.

  • Lyft's Platform fee charged to drivers is the difference between what passengers pay and the cumulative driver earnings. Unlike Uber's static 25% fee, this fee will vary.

  • The site also offers rental car programs for those without their own ride. All drivers are covered with Lyft's $1M insurance policy while driving.

What can you expect to earn?
Similar to Uber, average earnings for Lyft drivers are $11 - $15 per hour.

Hop Skip Drive

  • Payments are initiated weekly on Mondays and are reflected in your bank account on Tuesdays or Wednesdays (depending on your bank).

What can you expect to earn?
HopSkipDrive claims drivers can earn up to $30 per hour through their platform.

Get Creative

Earning extra cash doesn't have to feel like work. If you're a photographer, designer, or crafty with knitting needles, you can earn extra money by sharing your talents with the world.

When using any of these apps or websites, don't forget any transaction fees when estimating your monthly earnings.

Creative Market

Creative Market: One of the biggest online marketplaces for designers selling graphics, fonts, and illustrations.

  • Your listed items go live instantly. Set your own prices and keep 70% of the sale.

  • After making at least $20, you can request a payout. You will receive your earnings on the 15th of the following month.

  • Creative Market doesn't enforce exclusivity with their "shop owners," meaning you can sell the same products elsewhere on the internet.

What can you expect to earn?
Depends on how established you are within the community. On average established creatives earn around $500 per month.


Foap: Upload your photos and videos to this app and get paid by brands, agencies, or anyone browsing for content.

  • Download the Foap app and set up your PayPal information. Once you start selling photos, you can request a payout at any time.

  • Charge up to $60 for a photo and split the sale with Foap 50/50. To maximize your chances, be sure to caption and tag your photo or video appropriately.

  • Brands and agencies often host "Missions," which are special contests where selected photos and videos win larger payouts.

What can you expect to earn?
People who devote more time to listing their photos and monitoring the app will likely earn more. Join Foap's "Missions" and, if your photo or video is selected, you can earn $100 - $300.


Etsy: One of the first online marketplaces for selling handmade goods, Etsy boasts a network of 1.8M sellers.

  • Creating a shop on Etsy is free. But you'll pay a listing fee of $0.20 per item, as well as a 5% transaction fee and a 3% processing fee.

  • Use Etsy's support specialists to get tips on running a successful shop or communicate with fellow sellers in Etsy's community forums.

What can you expect to earn?
Well-established Etsy shop owners make an average of $500 from selling their items.

Look to the Medical Field

Medical institutes and schools are willing to pay for time and services rendered. These can range from simple studies, to donating plasma.

Since these options are a little more invasive, you may earn $300 - $500. Clinical trials can last a month or longer. If you need to make money quickly, consider donating plasma or participating in a shorter-term psychological study instead.

Program for Healthy Volunteers

Program for Healthy Volunteers: The National Institute of Health's online resource for those open to clinical trials. These sessions may be invasive or time-intensive.

  • The program offers trial opportunities for those with no significant health problems to test a new drug or device.

  • Search through the website's database of nationwide clinical trials to find one near you.

  • Compensation per study will vary. You may be entitled to additional compensation if asked to undergo a procedure.

Stanford Psychological Studies

Stanford Psychological Studies: Get compensated for psychological research done at the Stanford campus or online.

  • Stanford's Department of Psychology regularly conducts studies on the Stanford campus, but also offers opportunities for online experiments.

  • To participate in one of Stanford's studies, you'll need to complete a brief online questionnaire and provide your contact information.

  • Many of Stanford's studies are paid by the hour, with some offering as much as $20 for each hour for your participation.

Donate Plasma

Donate Plasma: Get paid to provide a life-saving resource for those in need.

  • Specific donor requirements will vary across donation centers. But all donors must be in good health, at least 18 years old, 110 pounds, and have not gotten a tattoo or piercing in the last 12 months.

  • Once you've confirmed your eligibility, refer to the CSL Plasma website to find a donation center near you. The donation process will generally take about 90 minutes.

  • Compensation varies, but CSL Plasma claims donors can make up to $400 a month.

Go Back to Basics

There's nothing wrong with taking the old-fashioned route. Think about hosting a garage sale, recycling, or offering yardwork services to your neighbors. Although they're low-tech options, you still stand to make a decent amount of extra cash.

A well-planned garage sale can net you $500 or more over the course of a weekend. When it comes to recycling and yardwork, the money will add up more slowly. 1,000 bottles at 10 cents each is $100 by month's end. Charging $20 a lawn for cutting the grass can earn you the same.

Garage Sale

A great way to unload your unwanted items in one weekend.

  • At least a week before you host your sale, check with local city ordinances and acquire any necessary permits.

  • If you don't have enough items for a solo sale, ask friends and family if they have things to sell. You'll have to split the earnings, but you may attract more buyers.

  • Put up at least 10 - 12 colorful signs around your neighborhood a few days before the event. Make sure your signs are clear, minimal, and include your address.


Do good for the environment while earning some extra cash.

  • States will pay varying amounts for recycled bottles and cans. Check the National Conference of State Legislature website to see if your state has a Bottle Bill.

  • Ask friends and family to set aside their bottles and cans and offer to pick them up weekly.

  • Check websites like Earth911 and RecyclingCenters.org to search for the locations and hours of recycling centers near you.

Neighborhood Yardwork

Help out your neighbors by cleaning up their yard (and get some exercise, too).

  • Consider what yardwork equipment you have and which seasonal tasks people are willing to pay for.

  • Print fliers, post them in local gathering spots, or advertise your services on neighborhood social networks like Nextdoor or community Facebook groups.

  • Make sure your clients are happy with your work. Repeat customers and referrals will help you earn more cash.

Bottom Line

Before taking on a new project or side hustle, be sure to do your research. Search for tips online, ask friends about their experiences, and plan accordingly.

Over the course of a month, you'll earn some extra cash and learn some new skills in the process.
