Strategy Comparison
Avalanche targets the highest-APR debt first — you pay the least total interest. Snowball targets the lowest balance first — faster early wins that build momentum and motivation.
Debt Payoff Calculator (Avalanche & Snowball) simulates avalanche (highest APR first) and snowball (lowest balance first) debt elimination strategies across up to 5 debts and shows months to debt-free, total interest, and savings vs. minimum payments only.
Enter up to 5 debts — credit cards, student loans, personal loans — and compare the avalanche method (highest APR first, saves the most interest) vs. the snowball method (smallest balance first, fastest early wins) to find your fastest debt-free date.

See your debt-free date, total interest, and payoff order for each method
Each month: interest accrues on all remaining balances; minimum payments are applied; extra payment goes to the target debt (highest APR for avalanche, lowest balance for snowball). Simulation runs until all balances reach zero or 600 months. Interest saved = total interest under min-only scenario minus total interest under the chosen strategy.
Avalanche saves the most total interest by targeting the highest-rate debt first. Snowball pays off smaller balances first for psychological momentum. If motivation is a challenge, snowball may help you stick to the plan; if you're disciplined, avalanche is mathematically optimal.
On $20,000 of combined debt at 18% APR, an extra $100/month could save several thousand dollars in interest and reduce your payoff by 2+ years. Use this calculator to find your exact savings.
If your debt APR is above 7–8%, paying it off first usually beats investing on a risk-adjusted basis. Below 5–6%, investing in a diversified portfolio may yield higher expected returns. Always match employer 401k contributions before paying extra debt.
Pay minimums on all debts, then apply every extra dollar to the debt with the highest interest rate. Once it's paid off, roll that payment to the next highest rate. This minimizes total interest paid.
