For most people, an additional income stream is life-changing. It provides additional financial security for you and your family, allows for the ability and opportunity to travel, and can even provide the chance to pay off debt.

Whether through investment accounts, freelance, or second job ideas, a supplemental income is a fantastic way to improve your financial standing. Even just a few extra dollars every month can give you and your family room to breathe by giving your budget a healthy buffer.

Keep scrolling for a few ways you can earn supplemental income. We hope that 2021 can be your year to thrive financially!


Use your nights and weekends a few times a month to babysit!

If you have experience with children, babysitting is a fantastic way to make supplemental income. Don’t know anyone looking for a babysitter? Try websites like Care.Com that connect you with local families in need of assistance. You can also advertise your services on social media.


Similar to babysitting, but arguably less complicated, you have the option to dogsit! People often go out of town for work or on vacation and need someone to watch their dogs (instead of boarding them, which can be considerably more expensive).

Post flyers advertising your services around your town, or check out the NextDoor app for people in need of a pet sitter.


Use weeks or weekends to house sit for friends, families, and friends of friends going out of town. Housesitting is an easy and quick way to make extra money! Typically, the job involves taking the trash out, picking up mail, watering plants, etc.

Again, check out places like Facebook Marketplace, NextDoor, or Care.com. When in doubt, ask around! One of the best ways to find supplemental income is through referrals and word of mouth.

Dog Walker

Love animals and exercise? Dog walking is a great way to combine both of these loves and make money. Download an app like Rover and sign up to be a dog walker.

It is a pretty simple process that connects you with people in your area looking for someone to walk their precious pups. You can also check out the NextDoor app!

Be a Driver

If you have your own means of transportation, many experts recommend driving through Uber, Taxi, or Lyft as a great way to make passive income. Drivers can make their own schedule, drive when they’re available, and keep tips from passengers. Driving passengers from point A to point B isn’t a bad way to make extra money.

*We recommend using eTip to request or obtain tips quickly, especially when passengers don’t have cash! It’s as easy as scanning barcodes, selecting amounts, and hitting send.

Complete Online Surveys

Make money without leaving your house by completing online surveys. Market research companies will pay users to fill out surveys about Products. You can sign up with websites like Global Test Market to sign up or learn more.


Pick up a few shifts at a local restaurant as a server or host! If you are a people person and have experience in waitressing, this is a fun way to get out there and make extra income.

Clean houses

According to the experts, you can make as much as $1,000 per month cleaning houses on the side, making it an excellent way to make money quickly. If you don’t mind rolling up your sleeves and doing hard work, this is a great option.


Money savvy or willing and wanting to learn? Try your hand at investing. NerdWallet has an excellent how-to on getting started.

Freelance what you are currently doing

Don’t quit your day job, do it on the side for yourself! Regardless of your industry, you can freelance your skills on the side for extra money. Sign up for websites like Freelancer.com to connect with people who need your services.

For example, do you work in marketing? Utilize UpWork to freelance your marketing abilities (i.e., social media management for small businesses who can’t afford agencies). If you are a designer, designing for clients or selling your work on Etsy or social media.
