Why net present value (NPV) matters to a first-time founder
NPV helps a founder compare money spent now with uncertain cash expected later. A positive result can support an investment, while a negative result warns that the assumed return may not justify the cost. The answer is only as reliable as the forecasts and discount rate behind it.
Examples of net present value (NPV)
A startup pays ₦100 million for equipment expected to generate ₦30 million at each year-end for four years. Discounting those receipts at 10% gives a present value of about ₦95.1 million, so NPV is roughly negative ₦4.9 million. On those assumptions, the project does not meet the chosen return.
Common misunderstanding
NPV is not a guaranteed profit forecast. It converts estimated future cash flow into today’s value and can change sharply when timing, demand, costs or the discount rate changes. A positive NPV also does not remove financing constraints, legal duties or risks that the model omits.
When to use it
Use NPV when comparing long-term projects, acquisitions or product investments with cash flows at different dates. State the discount rate, timing and scenario assumptions, then test pessimistic and optimistic cases. Ignore it for tiny reversible purchases where modelling effort would exceed the decision’s value.
