The Accelerated Debt Payoff Calculator is a free, embeddable calculator from CalcFunnel. See how adding an extra amount each month shortens your payoff and slashes the interest you pay.
You enter 4 inputs: balance, interest rate (APR %), current monthly payment and extra monthly payment.
It returns time saved, accelerated payoff, interest saved, interest (Accelerated) and interest (Base payment).
Built for credit counselors and consolidation lenders. Embedding it on your own website needs the Pro plan (from $150/month, with a 14-day free trial), which unlocks the Credit & Debt category.
The first figure — time saved — is the headline result.
Inputs
Each field below comes straight from the calculator, with the same help text visitors see when they hover the info icon.
