How to use this tool
- Enter a balance, annual interest rate and minimum payment for each debt.
- Set the extra amount you can pay each month.
- Compare minimums, snowball and avalanche, then switch payoff orders and compare extra payments.
How we calculate it
Adds one month of interest, pays each required minimum, then directs remaining money to the selected priority. Avalanche targets the highest interest rate; snowball targets the smallest current balance. As debts are repaid, the same total budget continues toward remaining debts.
Minimums only pays each original minimum without rolling unused payments into other debts. Rates and minimum payments stay fixed. A real card’s minimum may fall as its balance falls. No new charges, fees or promotional rates are modeled. A payoff estimate is unavailable when payments cannot cover interest or exceed a 50-year calculation period.
