What this calculator does
Compound a series of dated-by-period cash flows to a common future period.
How it works
The calculator evaluates FV at N = Σ CFₜ(1+i)^(N−t). Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
Input query strings and outputs
