Excel Percentage Calculations

The above Excel Percentage spreadsheet calculates two different types of percentage. These are:

Percentage Change

Example:

Month 1 sales: $1,000
Month 2 sales: $1,200
Percentage change from Month 1 to Month 2 = +20%

I.e. Sales have increased by 20% in Month 2, compared to Month 1.

Percentage as a Proportion

Example:

Sales of Widgets: $300
Total Sales: $1,000
Sales of Widgets as a proportion of Total Sales = 30%

I.e. Sales of Widgets accounted for 30% of the Total Sales.

For details on the formulas used to calculate these two percentages, see the Calculating Percentages in Excel page.
