Extra income is the fastest way to pay off student loans, because it doesn’t depend on cutting a budget that’s already tight. But most side income is smaller than the internet makes it sound, so it pays to pick the right kind and send every dollar straight to the loan.
I personally paid off $30,000 worth of student loans in under 12 months. I attribute some of that to having smart side hustles like finding ways to make extra money fast with answer questions for money apps and flipping items for a profit.
Here’s what actually pays, what’s pocket change, and how to make sure the money ends up on your loans instead of in your checking account.
The short answer
- Even $100 a month on a $25,000 loan at 6.52% cuts the payoff from 10 years to under 7 and saves about $3,161 in interest.
- Gig work (delivery, rides) and selling things you own bring in the most real money. Survey and game apps are pocket change.
- Side income is taxable. If you net $400 or more from self-employment in a year, you owe self-employment tax of 15.3% on top of income tax.
- Send the money to your highest-rate loan right away, and tell your servicer to put it on principal.
What a side hustle can do to your payoff date
Before picking a gig, it helps to see what the money is worth. Here’s a $25,000 loan at 6.52% on a 10-year plan, with the regular payment of $284.12 a month.
| Extra each month | Paid off in | Interest saved |
|---|---|---|
| $0 | 120 months | $0 |
| $50 | 97 months | $1,921 |
| $100 | 81 months | $3,161 |
| $200 | 61 months | $4,673 |
Our math: standard amortization at a fixed 6.52%, interest figured monthly, every extra dollar on principal. Your servicer charges interest daily, so real numbers will be a little different. Try your own balance in the student loan payoff calculator.
Notice the first $50 does a lot. You don’t need a second full-time job to change your timeline.
Side income ideas that actually pay
1. Deliver food or groceries
Delivery is the most flexible real money there is. With DoorDash, you decide when, where and how much you work, and you can take or skip any order. You need to be at least 18 (older in a few states), and in some cities a scooter or bike works instead of a car.
Pay is per order and depends on time, distance and tips, so it swings a lot by city and hour. Gas and wear on your car come out of it too. Track your miles from day one, since that’s what you’ll use to figure your taxes.
Our guide to driving for DoorDash goes deeper, and Gigs Done Right covers more side gigs in detail, and so does our list of the best gig economy jobs.
2. Sell stuff you don’t use
Old phones, game consoles, textbooks and clothes are cash sitting in a drawer.
It’s one-time money, but it’s fast, and a few hundred bucks dropped on a loan in one shot is a nice jump.
For tech, DeCluttr gives you a price up front and you mail it in. You’ll usually get more selling to a person directly, but it takes longer and you deal with buyers. Pick based on how much your time is worth to you.
3. Use a skill you already have
Tutoring, freelance writing, design, bookkeeping, pet sitting. If people already ask you for help with something, that’s the side hustle to try first. It usually pays more per hour than apps, and you set the price.
The side hustles guide at My Millennial Guide has a long list of these by skill and how fast they pay.
4. Survey and reward apps (small, but easy)
Survey and game apps pay a few bucks here and there, not a loan payment.
Even Survey Junkie says you won’t get rich taking surveys. They’re for downtime, like waiting rooms and the couch, and the best way to use them is to treat whatever they pay as a bonus that goes straight onto the loan the day it lands.
If you want to try a couple anyway:
- Survey Junkie lets you cash out from $5 by PayPal, bank transfer or gift cards.
- Swagbucks pays for games, surveys and shopping. Its $10 sign-up bonus only kicks in after you spend at least $25 at a store through Swagbucks within 30 days, so don’t count on it unless you were shopping anyway.
- Nielsen pays you in reward points for gift cards (up to $50 worth) when you sign up your phone, tablet or computer, with instant win games and survey invites on top. It’s about as passive as it gets.
- InboxDollars is another rewards site, and it shows a $5 bonus on its sign-up page.
- Mistplay pays in gift cards for playing new mobile games on iPhone or Android. It’s gift cards, not cash, so use them for things you’d buy anyway and send the cash you save to the loan.
For more apps with sign-up bonuses, ReferralWallet lists apps with sign-up bonuses, and beermoney.co and SavingLoop cover more apps that pay.
Route every dollar to the loans
Side income has a way of disappearing into regular spending.
The fix is simple: never let it sit in your checking account.
- Have gig payouts land in a separate savings account, not your everyday checking.
- Move your tax set-aside out first (see the next section).
- Once a month, send the rest to your loan with the highest interest rate as a separate extra payment.
- Tell your servicer to apply it to principal and not to advance your due date, then check the next statement.
Why the highest rate first? It saves the most interest. Our guide on how to pay off student loans faster walks through that, plus how to make sure extra payments actually hit principal.
Don’t forget taxes on side income
This is the part that trips people up.
Gig and side income is taxable even if you never get a 1099 form from the app or the client, so plan for the tax from your first payout instead of finding out when you file.
From the IRS
If your net earnings from self-employment are $400 or more in a year, you owe self-employment tax. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. That’s on top of regular income tax.
If you expect to owe $1,000 or more when you file, you generally have to make estimated tax payments during the year, using Form 1040-ES.
So set aside a slice of every payout in that separate account before anything goes to the loans. Being short in April and putting the tax bill on a credit card wipes out the interest you saved.
Net earnings means after expenses. Mileage, phone costs and supplies you use for the gig can lower what you’re taxed on, so keep records.
What’s realistic, and what to skip
A good side hustle for paying off student loans pays in cash, fits around your job and doesn’t cost much to start. Delivery, selling things and using a skill check those boxes.
Skip anything that asks you to pay to join, promises a fixed income for little work, or wants you to recruit friends to earn. And if a company calls offering to make your student loans disappear for a fee, hang up. Help with federal loans is free from your servicer and studentaid.gov.
Bottom line: pick one thing that pays real money, give it a few months, and send every dollar to the loan. Small, steady extra payments add up faster than you’d think.
Common questions about making money to pay off student loans
The best one is whatever pays you real cash on a schedule you can keep. Delivery and ride apps, selling things you own and freelancing a skill usually bring in more than survey or game apps, which pay small amounts and often in gift cards.
Any amount helps, and the first dollars do the most. On a $25,000 loan at 6.52%, an extra $50 a month saves about $1,921 in interest and an extra $100 saves about $3,161.
Yes. Side and gig income must be reported even without a 1099. If your net self-employment earnings are $400 or more, you also owe self-employment tax of 15.3%, and if you expect to owe $1,000 or more you generally need to make estimated payments.
Not by themselves. They pay small amounts for spare time. They can add a little to an extra payment, but gig work or a skill-based side hustle will move your balance much faster.
If you have no emergency savings, build a small cushion first so a surprise bill doesn’t go on a credit card. After that, send side income to your highest-rate loan.
