Formula
Months to Payoff = ln(P / (P - D × r)) / ln(1 + r)
Where: P = Monthly Payment, D = Debt Amount, r = Monthly Interest Rate
How it works
Months to Payoff = ln(P / (P - D × r)) / ln(1 + r) Where: P = Monthly Payment D = Debt Amount r = Monthly Interest Rate (Annual Rate / 12 / 100) Required Payment for Target Months = D × [r(1+r)^n] / [(1+r)^n − 1] Where: D = Debt Amount r = Monthly Interest Rate n = Number of Months Example: Debt: $10,000 Interest Rate: 5.5% annual (0.458% monthly) Payment: $500/month Months to Payoff ≈ 21 months ≈ 1.75 years
