Accelerated Debt Payoff Calculator
Consolidating your debt is only half of the battle. You still need a plan to get your debt paid in full. This calculator can show you how to accelerate your debt payoff.
How the accelerated debt payoff calculator works
It amortizes your total balance at your current payment and again with an extra amount added, then compares the two. Because the extra goes straight to principal, it removes the future interest that principal would have generated.
Worked example: with total debt balance of $18,000, average interest rate (apr) of 18.00% and current monthly payment of $450, the accelerated debt payoff calculator shows interest you would save of $4,260.
- Current payoff
- 5.2 yrs
- Accelerated payoff

- Interest (current)

- Interest (accelerated)

The formula
Each month: interest = balance × APR ÷ 12; principal = payment + extra − interest. Interest saved = total interest at the current payment − total interest with the extra.

Questions about the accelerated debt payoff calculator
How much does an extra payment accelerate payoff?
Substantially on high-rate debt. Because the extra reduces principal directly, it avoids all the future interest on that amount — the calculator shows the months and dollars saved.
Where should I find the extra money?
Trimming discretionary spending or directing a raise, tax refund or bonus to debt are common sources. Even a small, consistent extra payment compounds into a big saving.
Is paying off debt better than saving?
When your debt rate is higher than what you could safely earn saving or investing, paying it down is the guaranteed, higher return — which is usually true for credit-card debt.
Is the Accelerated Debt Payoff Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
