NPV
Net present value (NPV) is a financial metric used to evaluate whether a project or investment is expected to create value. This is achieved by comparing the value of money today to the value of expected future cash flows, considering both timing and risk.
In practical terms, NPV helps finance teams decide whether a capital investment — e.g., new equipment, technology, facilities — is worth pursuing. By discounting future cash inflows and comparing them to the initial cost, NPV shows whether an investment is expected to add to or reduce organizational value.
An NPV greater than zero is favorable, as it shows an investment is expected to make money; an NPV less than zero is unfavorable, as it shows an investment is expected to lose money.
What is NPV and why is it important?
Net present value (NPV) is a valuation technique used to estimate the value created or destroyed by a business decision, most commonly a capital investment. It measures the difference between the present value of expected future cash inflows (revenue), outflows (associated costs) including the initial investment, and opportunity costs.
Eighty-two percent of financial professionals say NPV is important to their organization’s decision-making process, according to the 2026 AFP Cost of Capital Survey. The metric accounts for the time value of money, recognizing that a dollar received today is worth more than a dollar received in the future. By translating future cash flows into today’s dollars, NPV provides a clear, dollar-based estimate of how much value an investment is expected to add to or subtract from an organization.
What is NPV used for?
NPV is primarily used for valuation and decision-making because it can help compare alternatives, prioritize projects and support capital allocation decisions. It is especially critical in capital budgeting, the process organizations use to evaluate capital investments and long-term projects, such as purchasing equipment, launching a new product line, or making strategic infrastructure investments.
Because NPV accounts for both cash inflows and outflows over the life of a project, it is particularly useful when comparing investments with different timelines, cash flow patterns or risk profiles.

NPV formula
The standard NPV formula discounts each expected cash flow to its present value (i.e., value in today’s dollars) and then subtracts the initial investment:
NPV = Cash flow (1 + i)t − initial investmentThe formula has three components that finance must consider in its analysis:
- Cash flow = Net cash flow in period t
- i = Discount rate: Used to discount future cash flows to their present value. It reflects the time value of money, investment risk and the opportunity cost of capital. It is often based on a company’s cost of capital, hurdle rate or required rate of return.
- t = Time period: Includes the idea that cash flows in the distant future are less valuable than cash flows in the near term and are subjected to the discount rate for a longer period.
The basic formula above works for projects with a fixed lifespan, e.g., a five-year equipment lease. For investments that are expected to last indefinitely, the terminal value needs to be considered.
Terminal value represents the value of all future cash flows beyond the explicit forecast period, which is usually five or 10 years. It assumes the business reaches a state where it grows at a constant, sustainable rate.
NPV calculation example
Assume a company is considering purchasing equipment for $200,000. The company’s discount rate is 10%, and the equipment is expected to generate the following net cash flows over four years.
Note that in finance, using parentheses is an industry shorthand to represent a cash outflow.
- Year 0 (Today): ($200,000)
- Year 1: $50,000
- Year 2: $60,000
- Year 3: $70,000
- Year 4: $80,000
The present value of each cash flow is calculated as follows:
- Year 0 (Today): ($200,000)
- Year 1: $50,000 ÷ 1.10 = $45,454.55
- Year 2: $60,000 ÷ 1.10² = $49,586.78
- Year 3: $70,000 ÷ 1.10³ = $52,592.04
- Year 4: $80,000 ÷ 1.10⁴ = $54,641.08
NPV (Sum of all years) = $2,274.45
Because the NPV is positive, the investment is expected to increase the company’s value.
Positive NPV vs. negative NPV
A positive NPV indicates that the present value of future cash inflows exceeds the initial investment and associated costs. In general, this suggests the investment is expected to increase organizational value.
A negative NPV means the investment’s discounted cash flows are less than its cost, indicating a net loss.
An NPV of zero suggests the investment is expected to break even on a present value basis.
What is a good NPV?
There is no universal benchmark for a “good” NPV. In general:
- Any project with an NPV greater than zero is considered financially acceptable.
- When comparing mutually exclusive projects on a purely financial basis, the option with the higher NPV is typically preferred because it will generate more money.
However, practical considerations such as strategic importance, regulatory requirements, funding constraints or ESG goals may lead organizations to pursue projects with lower or even negative NPVs.
NPV vs. IRR
NPV and internal rate of return (IRR) are closely related but provide different perspectives. NPV expresses value in dollar terms, while IRR expresses return as a percentage. In cases where the two metrics are in conflict, NPV is generally considered the more reliable indicator of value creation.

NPV FAQs
Does NPV account for risk?
Risk is reflected through the discount rate, which can be adjusted based on the investment’s risk profile.
When is NPV most effective?
NPV is most effective for evaluating cash flows over longer periods of time because the discount rate and time factors have minimal impact on periods of less than a year or two.
