What does a positive NPV mean?

A positive NPV indicates that the projected earnings (in present dollars) exceed the anticipated costs. This suggests the investment is profitable and will add value to the business or individual.

What is the 'Discount Rate'?

The discount rate represents the 'opportunity cost' of your money—the return you could earn elsewhere with similar risk, or the interest rate you pay to borrow the funds for the investment.

NPV Calculator - Net Present Value

Calculate the Net Present Value (NPV) of a series of cash flows to evaluate the profitability of a projected investment, accounting for the time value of money.

In finance, a dollar today is worth more than a dollar tomorrow. This is the 'Time Value of Money' principle. When evaluating a long-term project or investment that will pay out over several years, you cannot simply add up the future cash flows; you must 'discount' them back to their value in today's dollars. Net Present Value (NPV) is the gold standard for this calculation. Our NPV Calculator allows you to input an initial investment and a series of future returns, applying a discount rate to show you if the project will actually create value after accounting for the cost of capital.

How it Works

The tool takes each future cash flow and divides it by (1 + r)^t, where 'r' is the discount rate and 't' is the time period. It sums these 'Present Values' and subtracts the initial cost to arrive at the Net Present Value.

Calculation Formula

NPV = Σ [ CF_t / (1 + r)^t ] - Initial_Investment

Calculation Examples

1. **Project**: Invest $10,000 today. Get $4,000 for 3 years at a 10% discount rate. NPV = **-$53.34**.
