What is a Debt Payoff Calculator?

A Debt Payoff calculator demonstrates the mathematical power of extra monthly payments. It calculates the exact amount of money and time saved when you contribute more than the minimum required monthly payment.

  2. Debt Snowball: Target low-balance debts first to build momentum.
  3. Automate Extra Payments: Set up automatic recurring extra transfers right after payday.

  2. Input the annual interest rate on your debt.
  3. Enter your required minimum monthly payment.
  4. Add an optional extra monthly payment amount.
  5. See how many months and thousands of dollars in interest you save.

Worked examples

$15,000 debt at 15% APR: $350 min payment + $150 extra payment

Making a $350 min payment takes 56 months and costs $6,094 in interest. Adding $150 extra payment ($500 total) cuts payoff to 36 months, saving 20 months and $2,278 in interest.

$30,000 debt at 12% APR with $200 extra monthly payment

Adding $200 extra per month to a $30,000 loan saves over $5,400 in interest and eliminates debt years earlier.

Frequently asked questions

What is the Debt Snowball vs Debt Avalanche method?

Debt Snowball pays off smallest balances first for psychological wins. Debt Avalanche pays off highest interest rate debts first to mathematically minimize interest paid.

How do extra monthly payments affect debt payoff?

Extra payments go 100% directly towards reducing principal balance, bypassing interest charges and shortening payoff duration exponentially.
