II. A Step-By-Step Guide

The basic formula for calculating a percentage in Excel is simple: divide the number you want to find the percentage of by the total value, and then multiply the result by 100. Here’s the formula in more detail:

[number you want to find the percentage of] / [total value] * 100 = [percentage]

Let’s say, for example, that you want to find what percentage of your sales for the month came from a specific product line. You have the following data:

– Total number of students: 50
– Number of students who received A grades: 15

To calculate the percentage of students who received A grades, you would use the following formula:


This gives you a result of 30%, indicating that 30% of your students received A grades on their latest exams.
