Formula
Use NPV = Σ Cₜ/(1+r)^t, including the cash flow at time zero. Cₜ is cash flow at period t and r is the discount rate per period as a fraction. Cash flows use equal time intervals.

Scope and limitations
Educational estimate using your assumptions; no live rates, tax rules or investment recommendations. Returns can be negative and are not guaranteed.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
