Compare the Avalanche and Snowball methods across all your debts at once. See exactly when you'll be debt-free and how much interest each strategy costs.
Each month the simulation runs this loop for every debt until all balances reach zero:
Avalanche orders targets by highest APR; Snowball orders by smallest balance. The rollover of freed-up minimums is what compounds your progress.
With a $6,000 credit card at 22.9%, a $14,000 car loan at 7.5%, and a $22,000 student loan at 5.5% on an $800/month budget, Avalanche (credit card first) typically clears all three a little sooner and saves several hundred to a few thousand dollars in interest versus Snowball — while Snowball clears the credit card just as fast since it is also the smallest balance.
Calculate your monthly mortgage payment, total interest, and full amortization schedule — plus the often-ignored real cost of the loan after inflation erodes your fixed payment.
Calculate how your savings grow with compound interest — choose daily, monthly, quarterly, or annual compounding, add regular deposits, and see the real inflation-adjusted value.

Which strategy wins for you?
Both strategies cost almost the same here, so pick Snowball for the motivation of clearing Credit Card first.
