Excel is the most widely used tool for dealing with massive datasets. We can perform myriads of tasks of multiple dimensions in Excel. In this article, I will show you how to perform actual 360 Interest calculation in Excel. This is one of the methods to calculate interest rates with a given loan amount and interest rate.

## Introduction to 360 Interest Calculation System

Actual/360, also known as the 365/360 rule, is the most frequently used method by banks to calculate interest accrual. In this method, you need to divide the annual interest rate by 360 to get the daily interest rate. Then you multiply the daily interest rate by the number of days in the month. Thus you will get the interest rate for that month. After that, upon multiplying the loan amount by the monthly interest rate, you can calculate the interest amount.

The actual/360 method is used by most banks because it helps to standardize daily interest rates across the year. Another advantage of  360-day calculations over 365-day calculations is that the daily interest rate is slightly higher.

## 2 Steps to Perform Actual 360 Interest Calculation in Excel

The actual 360 Interest calculation is very simple to do in Excel. I have divided the entire process into 2 easy steps. Let’s see them one by one.

### Step 1: Write Down Required Information

The first step is to write down the information. In our example, the loan amount is \$50000, the annual interest rate is 5% and the number of days in the month is 31. ### Step 2: Calculate Interest Amount in Actual/360 Method

The next step is the calculation of the interest amount. We are going to calculate the interest monthly. To calculate,

• Go to C7 and write down the following formula
`=C4*C5/360*31` Formula Explanation:

• The Annual Interest Rate is 5%.
• I have divided 5% by 360 to get the daily interest rate of 014%.
• Then, I multiplied 014% by 31 and got the monthly interest rate of 0.43%.
• Finally, I multiplied \$50,000 by 43% to get the monthly interest.
• Then, press ENTER to get the output. ## Things to Remember

• The actual/360 method helps standardize daily interest rates across the year.
