How To Calculate Percentage In Google Sheets

How to Calculate Percentage in Google Sheets

Basic Percentage Calculation

To calculate a percentage in Google Sheets, use the formula =Part/Total. This will yield the percentage of a part relative to a total.

Example: =C2/B2 calculates the percentage of received orders in a fruit delivery scenario.

Setting Cell Format to Percent

Select the cell(s) you want to format as percentages. Click on the Format menu, choose Number, and then select Percent from the dropdown options. Any value in the selected cells will now be displayed as a percentage.

Percentage Change Calculation

To calculate percentage change, use the formula =(New Value - Old Value)/Old Value.

Example: =(B-A)/A calculates the percentage increase or decrease between two values.

To calculate the percent change from row to row, use the formula =(B3-B2)/B2.

Calculating Percentages with Absolute References

Use the formula =B2/$B$8 to calculate the percentage of a total. The absolute reference $B$8 will not change when copying the formula to other cells.

Using SUMIF to Calculate Percentages

To calculate the percentage of a total when values appear in multiple rows, use the SUMIF function. The formula is =SUMIF(range, criteria, sum_range)/Total.

Example: =SUMIF(range, criteria, sum_range)/$B$8 calculates the percentage for criteria that appear more than once.

COUNTIF for Percentages

The COUNTIF function helps in calculating percentages based on criteria. Use =COUNTIF(range, criteria)/COUNTA(range) to find the percentage of cells that meet specific conditions.

Example: To calculate the percentage of students who improved their scores, use =COUNTIF(ARRAYFORMULA(C2:C32-B2:B32), ">0")/COUNT(B2:B32).

Using IFERROR to Handle Errors

To avoid #DIV/0 errors when calculating percentages with zero values, wrap your formula with the IFERROR function. Example: =IFERROR((B-A)/A, 0) to safely calculate percentage change.

Multiplying and Dividing by Percentages

To increase a number by a percentage, use =Amount*(1+%). To decrease, use =Amount*(1-%).

Example: =A2*B2 finds the amount when you have the total and the percentage.

Example: =A2/B2 finds the total when you have the amount and the percentage.

Advanced Formulas for Percentage Calculations

To calculate percentages across multiple criteria, use COUNTIFS. Example: =COUNTIFS(range1, criteria1, range2, criteria2)/COUNTA(range).

Convert values to percentages using the TO_PERCENT function: =TO_PERCENT(value).
