Why this result matters

What this calculator helps you answer

A debt planning tool that compares payoff strategies across multiple balances and monthly overpayments. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.

This debt payoff calculator helps people organize multiple debts into a clearer repayment plan. It estimates payoff time, total interest, and how strategy choice affects the path, making it useful for credit card balances, personal loans, medical bills, and other stacked debts.

Formula and method

How the calculation works

The calculator adds monthly interest to each debt, applies each minimum payment, then directs any extra monthly payment using either the avalanche method (highest APR first) or the snowball method (smallest balance first). That process repeats until every debt is cleared or the budget is too low to make progress.

Example

Example multi-debt payoff plan

If you are balancing a credit card, personal loan, and medical bill at the same time, this calculator helps show how much faster the stack can disappear when you add a fixed extra payment each month.

FAQ

Common questions about this calculator.

Short answers to the questions people often ask before or after using the tool.

Question

What is the debt avalanche method?

Debt avalanche targets the highest-interest debt first while keeping minimum payments on the rest. It usually reduces total interest more efficiently.

Question

What is the debt snowball method?

Debt snowball targets the smallest balance first while maintaining minimums on the rest. It often creates faster early wins, which can help motivation.

Question

Why compare payoff strategies?

The best plan is not always the one with the mathematically lowest interest. Some people stay more consistent with visible early wins, while others prefer minimizing cost.
