Add every debt below — balance, interest rate, and minimum payment — plus anything extra you can put toward it each month. Pick snowball or avalanche and estimate a payoff order, projected debt-free date, and interest total from those inputs. Everything stays on this device: no account, no login, nothing sent anywhere.
At these payment amounts, this could take an unusually long time (or your minimum payments may not fully cover the interest). Double-check your numbers, or consider increasing your extra monthly payment.
Debt snowball targets your smallest balance first, no matter the interest rate — the appeal is momentum: paying off a full debt early feels like real progress and tends to keep people going. Debt avalanche targets your highest interest rate first, which is the mathematically cheaper path since it minimizes total interest paid over time. Neither is "wrong" — the best method is the one you'll actually stick with.
Debt snowball pays off your smallest balance first, regardless of interest rate, which tends to build momentum through quick wins. Debt avalanche pays off your highest interest rate first, which saves the most money in total interest. Avalanche is mathematically cheaper; snowball is often easier to stick with.
The calculator simulates your debts month by month: each debt accrues interest, minimum payments are applied, and any extra payment (plus the minimum payments freed up from debts you've already paid off) goes toward whichever debt is next in priority order for your chosen method. This is an estimate based on the numbers you enter and doesn't account for rate changes, new charges, or missed payments.
