Debt Payoff Calculator

Debt Payoff Calculator plans payoff across multiple debts using the avalanche method, extra payments, and a fixed or shrinking monthly budget.

Your debts

Uses the debt avalanche method (highest interest rate first) for the most cost-efficient payoff order.

Extra payments

Payment strategy

Keep total monthly payment fixed after a debt is paid off?

When a debt is paid off, that payment amount is applied to the remaining highest-interest debts. Your total monthly outlay stays the same.

Worked examples

Concrete numbers and cases you can check against the tool above.

Two cards, avalanche extra $100

Card A $4,000 at 22% APR, Card B $2,000 at 13%. Avalanche puts every extra dollar on A (higher APR) while you pay B’s minimum. An extra $100/month typically cuts months and hundreds of dollars of interest vs minimums-only. Snowball (smallest balance first) can feel better but usually costs more interest.

When to use Debt Payoff Calculator

Multiple debts compete for the same monthly dollars. Modeling avalanche payoff with extra payments clarifies timelines and interest savings.

Common use cases

  • Prioritize high-APR cards while paying minimums elsewhere.
  • Test what an extra $100/month does to freedom day.
  • Plan a shrinking budget if income is temporary.
  • Visualize payoff order before consolidating loans.

Inputs and outputs
