Every method pays the minimum on all debts, then throws your extra cash at one target debt. They differ only in which debt is the target — and that choice changes how fast you're free and how much interest you pay.

Avalanche always pays the least total interest, but snowball is often easier to stick with and can free up cash sooner. The right answer depends on your exact balances and rates — which is why this tool runs all six methods on your real numbers.
It depends on the debt type you choose. Loans / installment debt accrue simple interest each month at APR ÷ 12. Credit cards compound daily, so their effective monthly rate is slightly higher — the calculator models this for more accurate results. Payments are applied after interest each month, and freed-up minimum payments roll into the next target debt automatically.

It's any money you can pay each month above the combined minimum payments. The bigger this number, the faster every method gets you to debt-free.
