How to Pay Off Debt: Interest, APR, Snowball, Avalanche, and a Plan That Fits Your Life

To pay off debt, list every debt, pay the minimum on all of them, and put every extra dollar toward one target at a time. The debt avalanche method targets the highest interest rate first and saves the most money. The snowball targets the smallest balance first and gives you quick wins. Either one works if you stick with it.

1. What is debt?

Debt is money you owe, whether it's to a bank, a credit card company, a hospital or a friend.

Debt isn't always bad. A loan can help you buy a home, go to school, or get a car you need for work, but borrowing always costs something. Three words you'll see a lot:

• Principal is the amount you still owe, not counting interest and fees.
• Interest is what the lender charges you for borrowing. It's the price of the loan.
• Fees are extra charges, like a late fee.

Some debts are secured, which means they're tied to something you own, called collateral. A car loan is a good example: if you stop paying, the lender can take the car. Most credit cards are unsecured, so there's nothing for the lender to take back. But if you stop paying, the lender can still send the debt to collections or sue you.

Having debt doesn't make you bad with money, and you're far from alone. Your first job is simply to find out what each debt costs you.

2. APR, interest and minimum payments

APR stands for annual percentage rate, the yearly cost of borrowing. On a credit card, the APR is your interest rate. On a loan, the APR also includes some fees, so it can be a bit higher than the interest rate.

Here's what APR means in dollars. Say you owe $5,000 on a card with a 24% APR. Divide 24% by 12 months and you get about 2% a month, or about $100 of interest in one month. If you pay $150, only about $50 actually shrinks your balance, which is why card debt feels so slow.

Most cards figure interest every day on that day's balance, so real numbers differ a little. The idea is the same.

A minimum payment is the smallest amount you must pay by the due date to avoid a late fee. Paying only the minimum keeps you in good standing, but it can take years to clear a big balance.

Your statement balance is what you owed when your billing cycle closed. If you pay it in full by the due date every month, you usually pay no interest on purchases. The days between the statement and the due date are called the grace period. If you carry a balance, you lose the grace period, and interest starts on new purchases right away.

Where to find your real numbers

Your monthly statement lists your APR, minimum payment and due date. Look for the minimum payment warning box. It shows how long payoff will take if you pay only the minimum, and how much you'd pay each month to finish in three years. It's an eye-opener.

3. Make a list of every debt

Write down every balance, APR, minimum payment and due date, and note whether each account is current or behind. You can't pick a plan until you can see every debt in one place.

Meet Dana. Here are her debts:

Next, figure out what's left each month after rent, food, utilities, transportation and insurance. That's the most you can put toward debt. Dana finds an extra $200 a month, so she can pay $590 in total. Pick an amount that still lets you pay next month's rent and buy groceries.

4. What is the debt avalanche method?

With the debt avalanche method, you pay the minimum on every debt and put all your extra money on the debt with the highest APR. When it's paid off, you move that whole payment to the next-highest APR.

For Dana, that means Card A (26%) first, then Card B (18%), then the loan (10%).

Why does it work? A dollar paid on a 26% card saves you 26 cents a year in interest. The same dollar on a 10% loan saves only 10 cents.

• Upside: You pay the least interest overall.
• Downside: If your highest-rate debt is also big, it can take months to see one disappear, and some people lose steam.

5. What is the debt snowball method?

The debt snowball method also starts by paying every minimum. Then you put all your extra money on the smallest balance, no matter its rate. When it's gone, roll that payment into the next-smallest balance.

For Dana, that means Card B ($2,000) first, then Card A ($5,000), then the loan ($8,000).

• Upside: You knock out a debt fast. That win keeps you going, and you have one fewer bill to track.
• Downside: You'll usually pay more interest than with the avalanche.

Avalanche vs. snowball: Dana's results

Dana pays $590 a month either way.

The avalanche saves Dana about $212. The snowball gets her first win nine months sooner. The real hero is the extra $200 a month: compared with paying only the minimums, it saves her more than $3,700 and gets her out of debt about two years sooner.

Neither plan works if you keep using cards to pay for basics. Fix that first, even if it means a smaller extra payment for now.

6. What a bigger payment does

Here's one $5,000 card at 24% APR, with no new charges:

Going from $150 to $250 a month cuts about 30 months and saves almost $1,900. Try your own numbers with the debt payoff calculator. Just pick a payment you can keep making.

7. If you can't pay everything

If money is too tight to cover every bill, protect the ones with the worst consequences before you think about avalanche or snowball. Many counselors suggest this order:

1. Rent or mortgage, so you keep your home.
2. Utilities, like heat, power and water.
3. Food and basic medicine.
4. The car loan and insurance, if you need the car to get to work.
5. Unsecured debts, like credit cards and medical bills.

Then call your card companies. Ask, "Can you lower my rate or put me in a hardship plan?" A hardship program is a temporary deal that lowers your payment or rate while money is tight. Get any deal in writing.

A nonprofit credit counselor can also help. They might suggest a debt management plan, a repayment plan run by a credit counseling agency, usually at lower interest rates. Our guide to free and nonprofit debt help explains how to find a good counselor.

Debt settlement is different: a company tries to get your creditors to accept less than you owe. It's risky, because your credit takes a hit and forgiven debt can count as income at tax time. By federal rule, a company that sells debt relief by phone can't charge you until it has settled at least one debt and you've made a payment on that deal. Anyone who wants money up front is breaking that rule.

If your debts are too big to repay even with these changes, learn how bankruptcy works and talk to a lawyer or legal aid office.

8. Old debts in collections

A debt collector may contact you about an old debt. Every state sets a statute of limitations: a time limit for suing you over a debt. After it passes, a collector can still ask you to pay but can't win a lawsuit if you raise the time limit in court. In some states, even a small payment restarts the clock. Before you pay anything on an old debt, check your state's rule.

In New York, the time limit for most consumer credit debts, like credit cards, is three years. In New York, a payment after the three years are up does not restart the clock.

Never ignore court papers. If you're sued, respond by the deadline on the papers, even if you think the debt is too old. If you don't, the creditor can win automatically.

9. Should you consolidate?

Debt consolidation means rolling several debts into one new loan. For example, you might use a personal loan with a fixed rate to pay off two cards.

Compare the total cost, not just the monthly payment. Look for an origination fee, which is a one-time fee taken out of the new loan. Check whether the rate can change. A lower payment stretched over more years can cost more overall.

Consolidation only helps if the old cards stay paid off. If you run them up again, you'll have the new loan and new card debt.

10. Balance-transfer cards

Some cards offer a promotional APR on balances you move to them, which is a low or 0% rate that ends on a set date. You usually pay a balance-transfer fee, often a percentage of the amount you move.

Meet Luis. He moves $4,000 to a card with 0% for 16 months and a 3% fee, which is $120. The fee is usually added to the balance, so he owes $4,120. If he pays about $258 a month, he clears it in 16 months and pays only the fee. If he pays $150 a month, he still owes $1,720 when the 0% ends, and the regular rate, say 24%, kicks in on what's left.

To find the payment you need, divide the balance (including the fee) by the number of 0% months.

11. Pay debt or build savings?

Do both. If every spare dollar goes to debt and your car breaks down, you'll end up back on the card.

A good first goal is a small cushion of $500 to $1,000 for surprises. After that, put extra money toward debt. Once the high-interest cards are gone, build savings up to a few months of bills. Our emergency fund guide shows how.

What about retirement? If your employer matches 401(k) savings, many people put in at least enough to get the full match while paying down debt, because turning down a match is like turning down part of your pay.

12. Build a system you can keep

1. Pick your method. Avalanche to save the most, snowball for quick wins.
2. Automate the minimums. Set up autopay for at least the minimum on every account. Pick a date right after payday.
3. Set your extra amount. Base it on your budget, not a guess.
4. Aim the extra at one target. Spreading it thin slows you down.
5. Check in monthly. Look at balances, interest charged and any rate changes.
6. Adjust when life changes. A new job or a new bill means a new number.
7. Roll it forward. When a debt is gone, add its whole payment to the next target.

Common mistakes

• Paying extra on one debt while missing a minimum on another.
• Looking only at the monthly payment and ignoring total interest.
• Forgetting when a 0% promotional rate ends.
• Draining every dollar of savings, then borrowing again after one surprise bill.
• Ignoring a collection letter or court papers.
• Consolidating, then running the old cards back up.
• Paying a debt-relief company before it has settled anything.

Frequently asked questions

Is the avalanche always cheaper?

With the same total payment, yes, almost always. A 0% promotion or a loan fee can change the math, so check those first.

Is the snowball a bad choice?

No. It costs a bit more, but the best plan is the one you'll stick with. For Dana, the snowball cost about $212 more over 31 months.

Does paying off a loan early hurt my credit?

Not much. Your score might dip a few points when the account closes, but you save interest. Check whether your loan has a prepayment penalty, which is a fee for paying it off early.

Can I ask my card company for a lower rate?

Yes, and it often works. Call the number on your card and ask. If you're struggling, ask about a hardship plan. Get any deal in writing.

What if I'm being sued?

Respond by the deadline on the court papers and get legal help right away. Our debt help guide lists free options.

The bottom line

Debt gets easier once you can see the numbers. List your debts, protect your essentials, choose avalanche or snowball, and send every extra dollar to one target. Ask for help early, before a missed payment becomes a crisis.
