Lump-sum value model

Present value = future value ÷ (1 + r/n)nt. Future mode multiplies instead. This route handles one lump sum; Compound Interest owns contribution projections and Annuity owns payment streams.

Interpretation boundary

The result uses only the entered nominal rate, compounding frequency, and time. It does not model taxes, inflation, risk, fees, market values, or investment suitability.
