How the Debt Avalanche Calculator Works
The debt avalanche pays your debts highest interest rate first. You make every minimum payment, then send all spare money to the debt with the highest APR — the one costing you the most — until it’s gone, then move to the next-highest rate. This calculator keeps your total monthly payment constant and simulates the payoff month by month.
Mathematically the avalanche is the cheapest strategy: attacking the highest rate first removes the most expensive interest soonest, so you pay less overall and often finish a little sooner than the snowball. The trade-off is motivation — if your highest-rate debt is also large, it can take a while to see the first win.
minimums on all → extra to the highest APR → roll freed payments onward
Frequently Asked Questions
What is the debt avalanche method?
You pay minimums on all debts and put every extra dollar toward the highest-APR debt first. When it’s cleared, that money rolls to the next-highest rate, minimising total interest.
Why is the avalanche the cheapest method?
Because interest cost is driven by rate. Eliminating the highest-rate balance first stops the most expensive interest soonest, so you pay less than any other order.
How much more does the snowball cost than the avalanche?
Usually a little — it depends on the spread between your rates and balances. Enter your debts in both calculators to see the exact difference for your situation.
