Educational valuation under entered assumptions. Positive NPV is not a guarantee or a personal investment recommendation.

Signed operating cash flows

Sum each signed amount multiplied by its discount factor at the selected valuation date. Regular schedules use period endpoints; dated schedules use actual calendar days divided by 365. Use a discount rate consistent with the cash-flow period, currency, inflation treatment and risk assumptions. There is no universal suitable rate.

Terminal value

Terminal value = reference × (1 + growth) ÷ (discount − growth). Growth and reference use the same rate period as the discount rate. For dated cash they are annual. The model assumes the next receipt one such period after the terminal boundary. Discount must exceed growth. Growing terminal value can dominate NPV. The growth and discount spread is an assumption, not a verified long-term outcome.

Returns and recovery

PI divides PV of all gross positive cash flows by PV of all gross negative cash flows. Separate terminal cash remains separate; PI is undefined without payments. IRR candidates make a fixed signed ledger approximately zero within the searched rate domain. Multiple, absent or sensitive roots prevent a single-rate decision. PI uses every gross receipt and payment, including separately entered terminal cash. Recovery is reported only for a conventional net investment pattern, after all cash at the same time. It may be unavailable for mixed or financing cash flows.

Project Comparison

Project B uses A's valuation date, timing, frequency and row dates. Its discount rate must match A before comparing NPV. Enter B's separate terminal amount at A's terminal endpoint. IRR is not the ranking rule. Finite amounts are limited to 1 trillion per gross row, 126 operating rows and 200 years. Overflow is unavailable. Equality uses 64 machine epsilons times gross PV; tiny differences inside numerical uncertainty are break-even.
