NPV vs. IRR — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 21, 2023
NPV (Net Present Value) quantifies the present value of future cash flows, whereas IRR (Internal Rate of Return) identifies the discount rate making NPV zero.

Key Differences
NPV stands for Net Present Value and is a metric used in capital budgeting to assess the profitability of an investment. It calculates the present value of all expected future cash flows, discounted back to the present day. IRR, or Internal Rate of Return, is another crucial metric in capital budgeting. It represents the discount rate at which the NPV of a project or investment equals zero.
In essence, NPV provides a dollar value representation of the profit or loss an investment might generate, considering the time value of money. A positive NPV suggests that an investment should be profitable, while a negative NPV indicates the opposite. IRR, however, is expressed as a percentage and denotes the annual return on investment where the project breaks even in NPV terms.
When comparing multiple projects or investments, NPV can tell you which one is expected to add the most value in absolute dollar terms. On the other hand, IRR can tell you which project offers the highest percentage return on investment. Thus, while NPV focuses on absolute value, IRR emphasizes relative returns.
It's crucial to consider both NPV and IRR in decision-making, as they provide complementary perspectives. While NPV offers a clear monetary picture of potential gains or losses, IRR provides a percentage representation of the profitability, helping gauge the efficiency of the investment.
In some cases, NPV and IRR might give conflicting signals, especially when comparing mutually exclusive projects. A higher NPV might suggest one project is more valuable, while a higher IRR might favor another. In such cases, a deeper analysis considering both metrics and other factors becomes essential.

Compare with Definitions
NPV
The present worth of cash inflows minus the present worth of cash outflows.
If an investment has a positive NPV, it's expected to be profitable.
IRR
The annualized rate of earnings on an investment.
Companies compare IRR to their hurdle rate to decide on investments.
NPV
A tool to evaluate the profitability of an investment, considering the time value of money.
NPV calculations help businesses determine if a project is worth pursuing.
IRR
A metric that shows the percentage return where an investment neither gains nor loses value.
If the IRR of a project is 15%, it equates to an expected 15% return on investment.
NPV
A financial metric that calculates the net benefit of an investment in present value terms.
A negative NPV suggests that the project might not recover its costs.
IRR
A measure of the average annual return of an investment over its life.
Investors seek projects with IRR exceeding their required rate of return.
NPV
The discounted sum of future cash flows minus initial investment.
Companies use NPV to assess the net value of potential projects.
IRR
The break-even rate of return on a project or investment.
A project with an IRR of 10% means it's expected to generate a 10% return annually.
NPV
A measure of how much value an investment or project adds.
High NPV projects are typically favored by corporations.
IRR
The discount rate at which a project's NPV equals zero.
An IRR higher than the cost of capital indicates a potentially profitable investment.
Common Curiosities
How is IRR defined?
IRR, or Internal Rate of Return, is the discount rate at which a project's NPV is zero.
What does NPV stand for?
NPV stands for Net Present Value, representing the present value of future cash flows.
How does NPV account for the time value of money?
NPV discounts future cash flows back to present value, considering the time value of money.
Can a project have a positive NPV and negative IRR?
No, a positive NPV implies an IRR greater than the discount rate.
Why might NPV and IRR give conflicting signals for a project?
NPV and IRR might differ due to varying cash flow patterns, project lifespans, or capital constraints.
How do companies typically use NPV in decision-making?
Companies use NPV to evaluate if the projected returns of a project exceed its costs.
Why is NPV considered a superior metric by many analysts?
NPV provides a direct monetary measure of value addition, making it clear and actionable.
Why is considering NPV crucial in long-term projects?
NPV accounts for the time value of money, making it essential for accurately assessing long-term project value.
Which is better: a higher NPV or IRR?
Both metrics are valuable; NPV indicates absolute profitability, while IRR shows return efficiency.
Can IRR be used to compare projects of different sizes?
While IRR provides a percentage return, it doesn't account for scale. Pairing with NPV can give a fuller picture.
Is a project with an IRR higher than the discount rate always acceptable?
Generally, yes. If IRR is greater than the discount rate, the project has a positive NPV.
How does a change in the discount rate affect NPV?
As the discount rate increases, NPV typically decreases, and vice versa.
What happens when a project's IRR equals its cost of capital?
When IRR equals the cost of capital, the project's NPV is zero, suggesting a break-even point.
How do IRR and NPV relate to each other?
IRR is the discount rate at which a project's NPV equals zero. Both are vital in investment appraisal.
Is it possible for a project to have multiple IRR values?
Yes, projects with alternating cash flow signs can have multiple IRR values.
