Calculating Compound Interest in Google Sheets

Compound interest is a powerful concept in finance that allows your money to grow exponentially over time. Whether you're planning for retirement, saving for a big purchase, or investing in the stock market, understanding how to calculate compound interest is essential. In this blog post, we'll explore how to calculate compound interest using Google Sheets, and we'll provide you with the code for the formula.

The Compound Interest Formula

The formula to calculate compound interest is:

A = P * (1 + r/n)^(n*t)


  • A is the final amount
  • P is the principal (initial amount)
  • r is the annual interest rate (expressed as a decimal)
  • n is the number of times interest is compounded per year
  • t is the number of years

Using the Google Sheets Compound Interest Formula


When you enter the above formula into cell B6 of the compound interest spreadsheet, here’s the result you should get:

If you want to find the resultant amount in 10 years, you simply need to replace the value in cell B4 with 10, as shown below:

Your result amount would then be:

Using the Compound Interest Formula in Google Sheets

To calculate compound interest in Google Sheets, you can use the POWER and FV functions. Here's the formula you can use:

=FV(r/n, n*t, 0, -P)

Let's break down the formula:

  • r/n: This calculates the interest rate per compounding period.
  • n*t: This calculates the total number of compounding periods.
  • 0: This indicates that there are no additional periodic payments.
  • -P: This is the negative value of the principal, indicating an outgoing cash flow.

Using the FV Function

Let’s use the FV formula to calculate the compound interest in the same problem:

=FV(B2,B3*B4, 0, B1)

The result we get is as follows:

Notice that we specified the Principal amount value (cell B1) as a negative number. This is because we are depositing money (or paying out) to the bank / organization.
