Mathematical Basis & Formula Guide
This calculation model operates directly using continuous mathematical equations:
FV = P(1+r)^t + PMT * [((1+r)^t - 1) / r].
Calculations are computed locally on your device with high-precision 64-bit IEEE floating-point arithmetic. No financial or personal parameters are transmitted to any remote analytics or storage server.
