What is Debt Payoff?
The snowball method pays the smallest balance first for quick wins; the avalanche pays the highest rate first to minimize interest. Both roll freed-up payments into the next debt.
How it works
We simulate month by month: interest accrues on each balance, minimums are paid, and your extra budget attacks the next debt in strategy order until everything clears.
