Before diving into the practical aspects of calculating percentages in Google Sheets, it’s essential to have a solid understanding of what percentages are.

For a simple percentage calculation, you can use the formula: (Part / Total) * 100. This formula helps in finding what percentage one number is of another.

Calculating Percent Change

When you need to calculate the percentage change between two numbers, you can use the formula: ((New Value - Old Value) / Old Value) * 100. This is particularly useful for analyzing data trends over time.
