Calculation Formula
Fixed Length Mode
Calculate payment amount given principal, rate, and duration:
PMT = P × r_p / (1 - (1 + r_p)^(-N))
Where: P = Principal, r_p = Periodic Rate, N = Total Payments
Fixed Payment Mode
Calculate duration given principal, rate, and payment amount:
N = ln(PMT / (PMT - P × r_p)) / ln(1 + r_p)
Where: PMT = Payment Amount, P = Principal, r_p = Periodic Rate
