How this planner works

Add your debts and choose a target payoff date. This tool estimates the monthly payment needed to finish by that target.

This version uses the Avalanche method by default, meaning extra payment goes to the highest APR first.

The model works in monthly periods, so results are based on the target month, not an exact payoff day.

1) Your debts

Add each balance, APR, and minimum payment. Debt type is for labeling and summaries.

2) Goal

The calculator only uses the target month and year for payoff planning.
Uses monthly compounding (APR/12). Estimates only.

Scenario loaded from shared link.

  • Interest accrues monthly using APR ÷ 12 (monthly compounding).
  • Minimum payments are treated as fixed dollar amounts, not percent-of-balance formulas.
  • The calculator estimates the monthly payment needed to finish on or before your target month.
  • This version uses Avalanche logic: extra payment goes to the highest-APR active debt first.
  • As debts are paid off, their minimum payments roll into remaining debts automatically.
  • No teaser APRs, penalty APR changes, late fees, or lender-specific minimum rules are modeled.
