# Net Present Value (NPV) Calculator

Please enter the parameters of cash flow into the net present value (NPV) calculator below.

## What is Net Present Value (NPV)?

Net present value (NPV) is a measure of the profitability of an investment or project, taking into account the time value of money. It is calculated by subtracting the initial cost of the investment from the present value of the expected cash flows from the investment, and then discounting those cash flows back to the present using a discount rate. The higher the NPV, the more profitable the investment is expected to be.

## How to use this Net Present Value (NPV) calculator:

1. Enter the value of interest rate (without the percentage sign)
2. Enter initial investment in absolute term
3. Enter future cash flows. If you have multiple cash flows for several years, separate each cash flow value by a comma
4. Press calculate button
5. You can see the result below the button. The result shows the values of Net Present Value (NPV), Present Value (PV) and the Profitability Index (PI).

## Steps to calculate Net Present Value (NPV)

1. Determine the expected cash flows for the investment over the period of time being considered.
2. Determine the appropriate discount rate to use for the investment. This is typically the rate of return that could be earned on a similar investment with a similar level of risk.
3. Calculate the present value of each cash flow using the formula: PV = CF / (1 + r)^t, where PV is the present value, CF is the cash flow, r is the discount rate, and t is the number of periods.
4. Sum the present values of all the cash flows to calculate the net present value (NPV).
5. If the NPV is positive, the investment is considered to be worthwhile as it is expected to generate a return greater than the discount rate. If the NPV is negative, the investment is not considered to be worthwhile as it is expected to generate a return less than the discount rate.

## Why is NPV important?

Net present value (NPV) is important because it considers the time value of money and takes into account all future cash flows, both positive and negative, to determine the overall value of the investment. This allows investors to compare different investment options and make informed decisions about where to allocate their capital. Additionally, NPV can help managers and businesses evaluate potential investments and determine whether they are worth pursuing. This can help ensure that resources are allocated efficiently and that investments are aligned with the company's strategic goals.

## What is the relationship between Net Present Value (NPV) and Internal Rate of Return (IRR)?

The NPV (net present value) and IRR (internal rate of return) are both used to evaluate the potential profitability of a project or investment. The NPV calculates the present value of all expected cash flows, discounted by the cost of capital, and compares it to the initial investment to determine the profitability of the project. The IRR calculates the rate of return at which the NPV is equal to zero, which is the rate at which the investment would generate the same amount of cash as the initial investment.

The relationship between NPV and IRR is that the NPV is used to determine the overall profitability of a project, while the IRR is used to determine the rate at which the investment would break even. A positive NPV indicates that the project is profitable, while a negative NPV indicates that it is not. The IRR can be used to compare different investment options to determine which one has the highest potential return. However, the IRR can only be used if the cash flows of the project are regular and constant, which is not always the case. In contrast, the NPV can be used for any type of cash flow, but it may be more difficult to calculate.
