Universal Multi-Mode Investment Modeling
Real-world investment planning requires flexibility: sometimes you know your final wealth goal and need to discover how much to save monthly, what initial principal is required, or what annualized rate of return is necessary to reach financial freedom. This tool solves all five key financial variables algebraically and through high-precision numerical algorithms.
Active Mode Mathematical Formula
Based on your currently selected calculation target (End Amount), the model computes:
Where:
- FV: Total accumulated future wealth balance.
- P: Initial starting deposit (Principal).
- PMT: Periodic recurring contribution per interval (monthly or annual).
- r: Nominal annual interest rate (in decimal form).
- m: Compounding frequency per year ($365$ for daily, $12$ for monthly, $4$ for quarterly, $2$ for semiannual, $1$ for annual).
- p: Deposit frequency per year ($12$ for monthly, $1$ for annual).
- t: Total investment duration in years.
- i: Effective interest rate per deposit interval: i = \left(1 + \frac{r}{m}\right)^{m/p} - 1
- timingFactor: 1 when contributing at the beginning of the period, or 0 when contributing at the end.
