Debt Payoff Calculator

U.S. only tools

When you owe money on several accounts, the order you pay them off changes both the cost and the motivation. The avalanche method targets the highest interest rate first and minimizes interest. The snowball method clears the smallest balance first and produces quick wins.

Use the minimum payment shown on each statement, not the amount you plan to pay.

Debt"Visa", "Car loan" - whatever the statement calls it. It only labels the rows below.
BalanceThe payoff balance on that statement. This is the number the simulation starts from, not the credit limit.
APR %The APR on the statement for the balance you carry. It is applied monthly, at APR / 12.
MinimumThe minimum due this month. Every month pays all the minimums first, then sends what is left to the focus debt.

Showing the first 39 months of a 39-month plan. Every month pays the minimums first, then sends the rest to the focus debt.

The avalanche order costs $0.00 less than the snowball on these balances. Keep the same monthly budget and the plan holds.

Enter your debts, the extra amount you can commit each month, and this calculator runs the plan: the payoff order, the months to debt freedom and the total interest, with the alternative strategy costed alongside it.

About this debt payoff calculator

Whichever order you clear several debts in, the money you send each month is the same; what changes is which balance disappears first. The snowball and the avalanche are both run on your own accounts, printing the payoff order, the debt-free month and the interest bill under each, so the gap is a number rather than a slogan. If you want the two orders compared side by side instead of one at a time, the snowball versus avalanche calculator runs both, and the debt-free date calculator turns the same schedule into the month the last balance clears.

Interest accrues monthly at one twelfth of each APR, every minimum is paid first and the leftover budget is aimed at the focus debt, whose minimum then rolls forward when it clears. The simulation is client-side, so nothing about your accounts is uploaded, stored or attached to a profile.

Pick the order you will actually keep paying, because a strategy you abandon saves nothing. The model assumes fixed rates, no new spending, no late fees and full payments every month, so a rate reset or a missed month moves the date. An estimate, not financial advice; your lender's Loan Estimate overrides it.

How this debt payoff calculator works

How the simulation works

Every month, interest is charged on each balance at one twelfth of its APR, because a stated annual rate accrues month by month on whatever is still owed. Each debt receives its minimum payment first, and whatever is left of your budget is thrown at the focus debt - the one the chosen strategy points at. When a debt is cleared, its minimum payment rolls onto the next one, which is the snowball effect that makes the whole plan accelerate.

The simulation stops when every balance is zero, or after 100 years if the minimums cannot cover the interest - a case the page flags rather than pretending one strategy wins. Nothing about your spending, income or account behavior is assumed beyond exactly what you type in.

Snowball versus avalanche

Avalanche (highest APR first) mathematically costs the least, because it stops the most expensive interest first. Snowball (smallest balance first) usually costs slightly more but delivers the first cleared account sooner, and that early win is what many people find easiest to sustain long enough to finish the whole plan.

The results show the interest bill under both strategies on your own balances, so you can see how big the trade-off really is. On many debt stacks the gap is modest, which means the decision is often about motivation as much as money - and seeing the actual number lets you make that call honestly.

Finding the extra money

The plan only works with a payment above the minimums, because minimum-only payments barely outrun the interest. Look for money already flowing out rather than new income you have to invent: a subscription you no longer use, a just-finished car payment, overtime, or a balance transfer that temporarily removes the interest drag.

Even $100 a month turns a minimum-only plan from decades into years. The page is built around that fixed extra because it is the one lever most households actually control - and because the results make the connection between a small monthly choice and a much shorter debt-free date explicit.

How the two strategies really compare

Avalanche and snowball can land on the same payoff order when rates and balances rank similarly, and then the interest gap is small or zero - which is fine, because it means the choice is motivational and both are nearly equal on money. On the three-card example below the orders diverge and the gap is about $1,033, so the difference is real but not enormous.

That is the honest size of the strategy decision: neither method is a miracle, and neither is a mistake. The page runs both on your numbers instead of assuming one side is always cheaper, so you leave with the actual dollar figure rather than a slogan.

Worked examples

Each example below was run through the calculator on this page when the site was built, so the numbers match what you see when you enter the same inputs.

Four debts, snowball order

Your debts: 4 items · Extra payment each month: $300.00 · Payoff method: Snowball — smallest balance first

Time to become debt free

3 years 4 months

Paying $300.00 above the minimums on top of $605.00 of minimums clears $24,500 of debt by Feb 2030.

Total interest: $5,489.86 · Total paid: $29,989.86 · Debt-free month: Feb 2030 · Monthly budget: $905.00

Smallest balance first: the store card disappears quickly and its payment rolls forward.

Same debts, avalanche order

Your debts: 4 items · Extra payment each month: $300.00 · Payoff method: Avalanche — highest interest rate first

Time to become debt free

3 years 4 months

Paying $300.00 above the minimums on top of $605.00 of minimums clears $24,500 of debt by Feb 2030.

Total interest: $5,489.86 · Total paid: $29,989.86 · Debt-free month: Feb 2030 · Monthly budget: $905.00

Highest rate first: the store card and card A absorb the early extra payments.

Minimum payments only

Your debts: 2 items · Extra payment each month: $0.00 · Payoff method: Avalanche — highest interest rate first

Time to become debt free

6 years 10 months

Paying $0.00 above the minimums on top of $350.00 of minimums clears $15,000 of debt by Aug 2033.

Total interest: $9,207.89 · Total paid: $24,207.89 · Debt-free month: Aug 2033 · Monthly budget: $350.00

With no extra payment the plan takes far longer and costs far more interest.

Three cards, two orders

Your debts: 3 items · Extra payment each month: $300.00 · Payoff method: Avalanche — highest interest rate first

Time to become debt free

3 years 3 months

Paying $300.00 above the minimums on top of $380.00 of minimums clears $17,000 of debt by Jan 2030.

Total interest: $5,365.25 · Total paid: $22,365.25 · Debt-free month: Jan 2030 · Monthly budget: $680.00

Avalanche on these three cards clears in 39 months and costs about $5,365 of interest; snowball gets the small card gone in a year but finishes in 43 months at about $6,398 - a $1,033 gap, which is what the strategy choice is actually worth here.

Frequently asked questions

Which method should I actually use?

If the numbers are close, choose the one you will stick with. Avalanche saves the most interest; snowball produces the fastest first win. The best plan is the one you keep paying every month until the balances are gone.

Why does the calculator ask for minimum payments?

Minimums show how much of your budget is already committed. As each debt clears, its minimum is freed up and redirected, which is why clearing a small account accelerates the whole plan.

Should I pause retirement contributions to pay off debt?

Capture any employer match first — that is an immediate return that usually beats a credit card rate. Beyond the match, compare the guaranteed interest saved against the expected investment return and your need for cash reserves.

Is a balance transfer better than a payoff plan?

A 0% balance transfer can save real money if you clear the balance before the promotional rate ends and the transfer fee is small. It changes the interest rate, not the discipline: the payoff still has to come out of your monthly budget.

How accurate are the payoff dates?

The simulation assumes fixed rates, no new spending on the accounts, no late fees, and payments made every month in full. Real statements vary slightly with statement dates and rounding, so treat the date as a target rather than a promise.

Does paying off debt improve my credit score?

Usually, because credit utilization falls — and utilization is the second-largest factor in most scoring models. Closing the accounts can hurt slightly by reducing total available credit, so keep cleared accounts open if they have no annual fee.

Assumptions and sources

  • Interest accrues monthly on each balance at one twelfth of the stated APR, and minimum payments are applied before the extra payment, matching issuer billing order.
  • Snowball and avalanche follow the standard personal-finance definitions: smallest balance first and highest interest rate first.
  • This is an estimate tool, not debt, financial or credit advice. The payoff date is an estimate under fixed rates and no new spending; your issuer’s billing can shift it.
