Debt Payoff Planner

See how entered current payments affect your monthly room, then compare three payoff paths using the same debts.

Your debts

Entered current minimum payments drive the DTI estimate. Add as many debts as you need.

Debt 1

Debt-to-income ratio

Check inputs

Uses entered current minimum debt payments divided by gross monthly income.

Money left from gross income

Check inputs

Before taxes and deductions; after living expenses, entered current minimums, and your extra payment.

Payoff comparison

Each entered monthly payment remains fixed for these estimates until that debt is paid; actual creditor minimums can change. Snowball prioritizes the lowest balance. Avalanche prioritizes the highest APR. Both redirect freed-up payments to the next debt.

Keeps each entered monthly payment fixed until that debt is paid; freed-up payments are not redirected.
