What is the Debt Payoff Calculator?
Paying off several debts at once — credit cards, a car loan, a personal loan — raises an obvious question: which one should extra money go toward first? Add each debt's balance, interest rate and minimum payment, plus any extra amount you can put toward debt each month, and this calculator builds a full payoff schedule using two popular strategies.
The debt snowball pays off the smallest balance first for quick psychological wins, while the debt avalanche pays off the highest interest rate first to minimise total interest paid. The calculator shows the payoff order, months to debt-free and total interest paid for each method side by side, so you can choose the approach that fits how you stay motivated.

Questions people ask
What is the difference between snowball and avalanche?
Snowball pays the smallest balance first for quick wins; avalanche pays the highest interest rate first to save the most money overall.
Which method is better?
Avalanche minimises total interest paid; snowball can be more motivating because debts disappear faster — either works if you stick to it.
Does adding extra payments really make a big difference?
Yes, even a modest extra amount each month can cut months or years off a payoff timeline and save significant interest.
Should I pay off debt or invest first?
It depends on the interest rate versus expected investment return; high-interest debt (like most credit cards) is usually paid off first.
Is my financial data stored?
No, it is calculated locally in your browser and never uploaded.
