What is Net Present Value (NPV)?
Net Present Value (NPV) is a capital budgeting metric that calculates the present value of all expected future cash flows from a project, discounted at the required rate of return, minus the initial investment. A positive NPV indicates the project is expected to create value; a negative NPV indicates value destruction.
How It Works
- Forecast all incremental cash flows over the project’s life, including terminal value.
- Select a discount rate equal to the cost of capital or required return.
- Discount each cash flow to the present: CFt / (1 + r)^t.
- Sum the discounted cash flows and subtract the initial investment.
- Decision rule: accept if NPV > 0, reject if NPV < 0; rank competing projects by NPV size.
Saudi Context
PIF, SIDF, and Vision 2030 program offices use NPV alongside IRR and payback period to evaluate giga-project investments. Saudi corporates typically use a Weighted Average Cost of Capital (WACC) in the 9% to 12% range, reflecting the SAR risk-free rate plus an equity risk premium and country adjustment.
Example
A factory upgrade requires SAR 5 million upfront and generates SAR 1.6 million per year for five years. At a 10% discount rate, the present value of inflows is SAR 6.06 million. NPV = 6.06 – 5.0 = SAR 1.06 million. The positive NPV signals the project creates value and should be accepted.
