Formula for Calculating Months to Pay Off Debt
The formula for loan payoff time is derived from the loan amortization equation: N=lnโก(PMTPMTโ(rรP))lnโก(1+r)N = \frac{\ln \left(\frac{PMT}{PMT – (r \times P)}\right)}{\ln(1 + r)}N=ln(1+r)ln(PMTโ(rรP)PMTโ)โ
Where:
- NNN = Number of payments (months)
- PPP = Loan principal (outstanding balance)
- PMTPMTPMT = Monthly payment
- rrr = Monthly interest rate (annual rate รท 12)
This equation calculates the exact number of months required to pay off debt at a fixed payment amount.
