1. Adjust the sliders to compute the net present value of an investment or service over its full lifetime.

2. Save or share your custom scenario:

Upfront costs/revenues are assumed to occur immediately (they are not time-discounted). End of life costs/revenues are assumed to occur immediately at the asset's end of life (they are time-discounted by the total life span). All time periods in between assume that cash flows at the end of the period.

The calculator uses full numerical precision internally, but it rounds all displayed values for clarity and to reflect the many uncertainties in predicting the future.

Interest rates shown are always annual rates.
