Understanding Basic Percentage Formulas in Excel

is essential for anyone looking to perform calculations involving percentages in their spreadsheets. Excel provides powerful tools for calculating and analyzing data, including the ability to easily calculate percentages with just a few simple formulas.

One of the most common percentage formulas in Excel is for finding the percentage of a number. This can be done using the formula: =(part/whole)*100. In this formula, “part” represents the portion of the whole that you want to find the percentage of, and “whole” represents the total. For example, if you want to find 20% of 50, the formula would be: =(20/50)*100, which would result in 40. This formula can be easily applied to any set of data to find the percentage of one value relative to another.

Another useful percentage formula in Excel is for calculating the percentage change between two numbers. The formula for this is: ((new value – old value)/old value)*100. This formula allows you to quickly calculate the percentage increase or decrease between two values. For example, if last month’s sales were $5000 and this month’s sales are $6000, the percentage increase would be: ((6000-5000)/5000)*100, which would result in 20%. This is a valuable tool for analyzing trends and changes in data over time.
