Calculation notes and example
Monthly payoff simulation and strategy rules
For each account, monthly interest equals opening balance multiplied by APR divided by 12. The minimum payment is applied after interest, and extra payment reduces the selected target's principal. In single-debt mode, the page compares minimum-only with minimum plus extra. In multi-debt mode, avalanche targets the highest APR and snowball targets the smallest balance while minimums continue elsewhere. When an account closes, its minimum rolls into the extra-payment pool. A plan is flagged when available payment does not cover monthly interest.
Avalanche versus snowball example
Consider $8,000 at 22%, $5,000 at 14%, and $12,000 at 7%, each with its required minimum, plus $300 of monthly extra cash. Avalanche sends the extra to the 22% balance and normally minimizes modeled interest. Snowball sends it to the $5,000 balance and may close an account sooner. The page shows the actual difference in time and interest rather than assuming one behavioral benefit fits everyone.
Inputs that can invalidate the schedule
- Use current balances, APRs, and required minimums from statements; penalty rates, promotional expirations, and changing minimum formulas are not forecast automatically.
- Do not count an account's minimum as extra until that account is paid off, and continue every required payment while targeting another balance.
- The model assumes no new charges, fees, skipped payments, or rate changes. Rerun it after any of those events.

How to interpret the debt payoff result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this debt payoff estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

How to Use
- Enter your debt balance, APR, and minimum monthly payment to see your baseline payoff timeline.
- Add an optional extra monthly payment to see how many months and how much interest you could save.
- Review the month-by-month amortization table to understand how each payment is split between principal and interest.
- Switch to Multiple Debts mode, add each debt, and compare Avalanche vs Snowball to choose a repayment strategy.
Frequently Asked Questions
What is the Avalanche debt payoff method?
The Avalanche method puts extra money toward the debt with the highest interest rate while making minimum payments on the rest. This strategy usually saves the most money overall because it reduces the most expensive debt first.
What is the Snowball debt payoff method?
The Snowball method puts extra money toward the smallest balance first while making minimum payments on the other debts. It may cost a bit more in interest than Avalanche, but many people like the quick wins and motivation from paying off accounts faster.
Should I pay extra toward debt every month?
Usually yes, if you already have a basic emergency fund and your debts have meaningful interest rates. Even small extra payments can shorten your payoff timeline by months or years and reduce total interest substantially.
Why does my debt never get paid off with low payments?
If your payment is too close to or below the monthly interest charge, the balance shrinks very slowly or can even grow. This is called negative amortization. Increasing your monthly payment or lowering your interest rate is the fix.
