Percentage formulas in Google Sheets are mathematical expressions used to calculate percentages. These are ratios or fractions expressed as parts of 100 and are essential for tasks ranging from financial analysis and academic grading to data analysis and general arithmetic.

Here are some common types of percentage formulas used in Google Sheets:

This formula calculates how much a single product's sales contribute to the total sales.

**Setup in Google Sheets:**

Enter the formula =(Sales of Product/Total Sales)*100 in a cell. Replace 'Sales of Product' and 'Total Sales' with the appropriate cell references.

Press Enter to get the result.

Optionally, format the cell as a percentage. If you prefer to use Google Sheets' percentage formatting (by clicking the '%' icon), you should not multiply by 100 in the formula as Sheets automatically does this when applying the format.

This formula calculates the percentage difference between two numbers, which is useful in comparisons like analyzing changes in values over time.

**Setup in Google Sheets:**

Press Enter to obtain the new charge amount.

This formula is used to find the participation rate of a class in an event.
