Side Hustles to Pay Off Debt: How to Make Extra Income Work Harder

A side hustle is a way to earn extra money outside your main job. Taking on a side hustle can be a practical way to create more room in your budget, but earning extra money is only half the equation. If your goal is to get out of debt, what you do with that extra income can make a bigger difference than how you earn it.

Whether you’re freelancing, picking up gig work, selling things online, or taking on occasional jobs, having a plan for your additional income can help you make meaningful progress toward your debt payoff goal.

Side hustles to earn extra income: ideas and costs

There are plenty of side hustle options out there to consider, including:

• Freelancing: Writing, graphic design, bookkeeping, photography, consulting, or other professional skills. Start with services you can offer using skills and tools you already have.
• Gig work: Driving, delivery, grocery shopping, or other app-based work. Include unpaid waiting time when comparing what different gigs pay.
• Selling goods: Selling unused belongings or making and selling products online. Selling belongings can provide a one-time boost; selling products regularly requires accounting for materials, fees, shipping, and returns.
• Tutoring: Academic subjects, test preparation, music, or other skills you know well. Recurring sessions may make income easier to plan around, but allow for preparation time and cancellations.
• Pet care: Dog walking, pet sitting, or boarding. Check how travel time, supplies, platform fees, or insurance affect what you keep.
• Home services: Cleaning, lawn care, home repairs, or other hands-on services. Start with services you can safely provide using equipment you already own.

The best option depends on your skills, schedule, and resources. If you already have experience or equipment, you may be able to start earning without spending much upfront.

It's also important to consider net income rather than gross pay. Driving and delivery work, for example, can come with fuel, maintenance, depreciation, insurance, and toll costs. Freelancers may need to pay for software, supplies, equipment, or platform fees. So, keep in mind that a side hustle that advertises $25 an hour may not actually put $25 an hour in your pocket.

Tip: To compare options fairly, divide what you keep after work expenses and setting aside taxes by all the hours you spend, including travel, preparation, and finding customers.

Taxes matter, too. Gig and freelance income is generally taxable, even when the work is temporary or part-time. Keep records of your income and eligible business expenses and set aside money for any taxes you may owe. The IRS gig economy tax center explains the basics.

Finally, consider whether there is actually enough demand for the work. Before investing significant money or time, research what customers are willing to pay and how much paid work is realistically available.

WARNING: Watch for job scams before sharing personal information or accepting an offer. Requests to pay for a job or deposit a check and send money back are warning signs.

Tips for using a side hustle to get out of debt quickly

Having extra cash available to help repay your debts is great, but how you use that money will make a huge difference in how fast you’re able to become debt-free.

Start with a clear debt payoff goal

Before looking for ways to earn extra income, determine exactly what you want that money to accomplish.

Start by making a list of your debts, including:

• Current balance
• Interest rate
• Minimum monthly payment
• Due date

Then decide how much additional money you’d like to put toward your debt each month. For example, if you determine that an extra $400 per month could significantly accelerate your payoff timeline, that gives you a concrete target when evaluating side jobs for debt payoff.

A specific goal can also help you avoid a common problem with side-hustle income: treating it like extra spending money. Without a plan, an additional $400 this month can easily disappear into dining out, shopping, or other expenses without making much progress on your debt.

Choose side jobs for debt payoff that fit your plan

Your side hustle doesn't have to generate a huge amount of money to make a difference. What matters is whether the income is consistent enough to support your goal. For example, if your goal is to put an additional $400 toward debt each month, a side job that reliably generates $400 to $500 after work expenses and taxes may be a better fit than one that produces $100 one month and $900 the next.

You should also make sure your side hustle fits around your primary job and other responsibilities. Taking on so much work that you risk burnout or your main source of income can undermine your overall financial goal.

Put your extra income toward the highest-interest debt

Once you've decided how much side-hustle income you can put toward debt, give every extra dollar a job.

One approach is the debt avalanche method. With this strategy, you make the minimum payment on every debt, then put any remaining debt-payoff money toward the debt with the highest interest rate.

For example, imagine you have:

• Credit card A: $5,000 at 25% APR
• Credit card B: $3,000 at 18% APR
• Personal loan: $8,000 at 10% APR

You would continue making the required payments on all three debts while directing your extra side-hustle income toward Credit Card A. Once that balance is paid off, you would put the money you had been paying toward it toward Credit Card B, and then the personal loan.

The reason is simple: Higher-interest debt costs you more over time. Paying it down first can reduce the amount of interest you pay as you work toward becoming debt-free.

If your side hustle income varies from month to month, you don't necessarily need to wait until you have a consistent amount. You can make additional payments whenever you have funds available, while still maintaining enough money to cover your regular expenses and required minimum payments. For more guidance, see MMI's advice on paying off debt with inconsistent income.

Build a small emergency fund, too

Putting every dollar of extra income toward debt may seem like the fastest approach, but having no savings can create another problem.

An unexpected car repair, medical expense, or household bill could force you to use a credit card again if you don't have any cash available. Ideally, you want to build an emergency fund that covers several months of living expenses. However, that can feel like an unrealistic goal when you're already struggling with debt.

If you're starting with nothing, even $1,000 in emergency savings can provide an important buffer against unexpected expenses. If $1,000 feels out of reach, start with an amount you can manage and build from there.

Once you've established a basic rainy-day fund, you can direct more of your side-hustle income toward your debt.

Make a plan for every side-hustle payment

One of the simplest ways to make extra income work toward your goal is to decide where it goes before you receive it.

For example, you could establish a rule that your side-hustle payments go toward your financial priorities rather than your everyday spending. Depending on your circumstances, that might mean:

• Setting aside money for taxes and necessary business expenses.
• Maintaining your emergency savings target.
• Making your regular minimum debt payments.
• Applying additional money to your highest-interest debt.
• Increasing the amount you put toward debt as balances are paid off.

For example, if you have $300 left after work expenses and taxes and set aside $50 for emergency savings, you could put $250 toward debt. Repeating that for 12 months would add $3,000 in debt payments, before considering any interest savings.

You can also automate transfers to a separate savings account or make an extra debt payment as soon as your side-hustle income arrives. The goal is to avoid letting extra money sit in your checking account long enough to become tempting to spend. If payments are irregular, schedule transfers only after the money arrives and essential expenses are covered.

Use your side hustle as a tool, not the entire financial plan

Taking on extra work can help you accelerate debt repayment, but it doesn't have to be your only strategy.

The right side hustles to pay off debt can give you additional money to put toward your balances. Combining that extra income with a clear repayment strategy, a small emergency fund and efforts to reduce the cost of your debt can help you make that money work harder.

What if your side hustle isn't enough?

If a side hustle isn't enough to cover your debt payments, a credit counselor can help you review your budget and repayment options.

Reducing the cost of your existing debt can make every additional dollar you earn more effective. For example, if you're able to lower the interest rate on your debt, more of your monthly payment can go toward reducing the principal balance rather than paying interest.

This is where professional help can be useful.

MMI's certified counselors can review your income, expenses, and debts to help you create a customized debt payoff strategy. Depending on your situation, MMI may be able to help reduce interest rates, making your existing payments more affordable and allowing additional income from a side hustle to go further.
