Debt Payoff Formula

n = –log(1 – P×r/PMT) ÷ log(1 + r)
n = Months to pay off debt
P = Current balance
r = Monthly interest rate (annual rate ÷ 12)
PMT = Monthly payment amount

ℹ️ Total interest = (PMT × n) – P. Your payment must exceed the monthly interest charge.

Frequently Asked Questions

💡

Pro Tips

1

Pay off the highest interest rate debt first (avalanche method) to minimise total interest paid mathematically. But the snowball method (lowest balance first) works better psychologically for many people.

2

If your payment doesn't exceed the monthly interest charge, your balance grows forever. Run this calculator first to ensure your payment is sufficient before committing.

3

Balance transfer cards with 0% introductory APR can save hundreds if you can pay off the balance within the promotional period — but read the fine print on fees and reversion rates.

4

An extra $100/month toward a $10,000 credit card at 19.9% APR reduces payoff time from 10+ years to under 5 years and saves over $6,000 in interest.
