How to use Net Present Value Calculator

NPV is the compensated sum of CF(t)/(1+r)^t. The entered rate applies to each equally spaced period, not automatically to a year.

1–1,201 cash flows, rate greater than −100% and at most 1,000%. Extreme discounting is rejected. No project acceptance or return guarantee.
Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
Educational user-assumption arithmetic only. No live rates, tax rules, financial advice, or outcome guarantees.
