What this calculator is useful for
Enter every debt you have, decide on a strategy, and see exactly when each one disappears. Avalanche minimises interest paid; snowball gives faster psychological wins.
Use it to turn several balances, rates and minimum payments into one payoff plan. The calculator is especially helpful when the emotional order of debts differs from the mathematically cheapest order.
How to read the result
Avalanche usually reduces total interest, while snowball can create faster visible wins. The right result is the plan you can actually keep paying, not only the one with the lowest theoretical cost.
What to check next
Before changing payments, keep a small cash buffer and confirm that extra payments reduce principal. Some loans have fees, fixed schedules or rules that change the payoff math.
Plain-language notes
Use this section if the finance words on the page are new to you. The calculator is meant to support a decision, not to reward perfect terminology.
-
APR/interest rate: the yearly cost of borrowing. A higher rate usually makes debt more expensive and payoff slower.
-
Principal: the original debt or mortgage balance before interest is added.
What to compare
Compare at least two scenarios before trusting the first answer. A useful result should tell you what changes if income, costs, rates, or timing move.
