🛠 Behind the Scenes: How It Works
The tool uses a compound interest formula that accounts for recurring contributions and different compounding frequencies.
The general formula:
FV = P * (1 + r)^n + PMT * [((1 + r)^n - 1) / r]
Where:
- FV = Final Value
- P = Initial Principal
- r = Periodic Interest Rate
- n = Total Number of Periods
- PMT = Periodic Contribution
This ensures precise, mathematically-sound projections.
