How it works
Add monthly rounded interest, pay fixed minimums, then allocate all remaining budget to the smallest remaining balance (snowball) or highest rate (avalanche). Freed minimums stay in the fixed budget.

Common questions
Why can snowball and avalanche results differ?
Snowball prioritizes the smallest remaining balance after minimum payments; avalanche prioritizes the highest interest rate. The same fixed monthly budget is reused until all modeled balances are paid.
