RATE function

Microsoft Excel’s RATE function is a financial formula that helps you calculate the interest rate for an investment or loan based on periodic payments and a constant principal amount. In simple terms, it tells you the interest rate you would need to earn or pay to achieve a specific financial goal.

RATE(nper, pmt, pv, [fv], [type], [guess])

How to Use

The RATE function in Excel is commonly used in financial planning and investment analysis. Here’s how you can use it:

Example 1: Calculate the interest rate for a loan with the following details:

In this example, the loan has 5 payment periods, each with a payment of \$200, a present value of \$1,000 (the loan amount), and no future value. The function will return the interest rate necessary to repay this loan.

Example 2: Determine the interest rate required to save a specific amount of money for retirement:

In this case, the person wants to save \$1,000,000 for retirement in 25 years by making no periodic payments. They currently have \$50,000 saved. The function calculates the interest rate they need to achieve this goal.

Example 3: Calculate the interest rate for an investment with periodic deposits:

This example involves making 10 annual investments of \$500 each with a future value of \$10,000. The type is set to 1 (payments at the beginning of each period), and a guess interest rate of 7% is used.
