# Net Present Value (NPV) Rule: Definition, Use, and Example.

What Is the Net Present Value Rule?

The net present value (NPV) rule is a financial decision-making tool that businesses use to evaluate investment opportunities. The NPV rule states that businesses should only invest in projects with positive NPVs; that is, projects whose present value is greater than their initial investment.

To calculate NPV, businesses discount the expected future cash flows of an investment project by the project's required rate of return. If the NPV is positive, the project is typically considered to be a good investment; if the NPV is negative, the project is typically considered to be a bad investment.

Example of How the Net Present Value Rule Works

To illustrate how the NPV rule works, let's consider the following example.

A company is considering investing in a new manufacturing plant. The plant is expected to cost \$100 million to build and will have an expected life of 10 years. The company expects the plant will generate annual cash flows of \$30 million for the first five years, \$40 million for the next three years, and \$50 million for the final two years.

The company's required rate of return is 10%. To calculate the NPV of this investment, we discount the expected future cash flows by the required rate of return to get the present value of those cash flows.

Year 1: \$30 million / (1 + 0.10)^1 = \$27.3 million
Year 2: \$30 million / (1 + 0.10)^2 = \$24.9 million
Year 3: \$30 million / (1 + 0.10)^3 = \$22.6 million
Year 4: \$30 million / (1 + 0.10)^4 = \$20.5 million
Year 5: \$30 million / (1 + 0.10)^5 = \$18.6 million
Year 6: \$40 million /

##### What is the formula of net value?

The formula for net value is: Net Value = Price - Expenses.

This formula can be used to calculate the net value of anything, from a business to a piece of property. To calculate the net value of a business, simply subtract the total expenses from the total revenue. To calculate the net value of a piece of property, subtract the total of all mortgage payments, insurance, taxes, and repairs from the purchase price.

##### What is future value example?

The future value (FV) of a present value (PV) investment is the value that the investment will have at some point in the future. The future value is determined by the interest rate and the length of time that the investment is held.

For example, let's say that you have \$1,000 to invest. You could put it into a savings account that pays 2% interest per year. In this case, the future value of your investment would be \$1,020 after one year, \$1,040 after two years, and so on.

Alternatively, you could invest the \$1,000 in a stock that pays no dividends and is expected to increase in value at a rate of 10% per year. In this case, the future value of your investment would be \$2,000 after one year, \$3,000 after two years, and so on. What is simple interest example? Simple interest is a quick and easy way to calculate the interest charge on a loan. Essentially, simple interest is calculated by multiplying the loan's interest rate by the number of days that have elapsed since the loan was taken out. For example, if you took out a loan for \$100 at an interest rate of 10% and it has been 30 days since you took out the loan, your simple interest charge would be \$10.

### What is an example of present value?

The present value of an asset is the value of that asset in today's dollars. For example, if you have a \$100,000 bond that pays 5% interest and matures in 10 years, the present value of that bond is \$100,000/(1+0.05)^10 = \$67,737. This is the amount of money you would need to invest today in order to have \$100,000 in 10 years. Why is it called NPV? The Net Present Value (NPV) is the present value of all future cash flows generated by an investment, minus the initial investment amount. The NPV is used to determine whether an investment is worth undertaking, as it represents the expected return on investment.

The name "NPV" comes from the fact that, in order to calculate the NPV, the initial investment amount is subtracted from the present value of all future cash flows. This results in a "net" present value, which is either positive (indicating that the investment is expected to be profitable) or negative (indicating that the investment is not expected to be profitable).
