Working out percentage increase in Google Sheets is an essential skill for anyone who uses spreadsheets to track data, analyze trends, and make informed decisions. Whether you’re a student, a business owner, or a financial analyst, being able to calculate percentage increase is crucial for understanding changes in data over time. In this comprehensive guide, we’ll walk you through the step-by-step process of working out percentage increase in Google Sheets, covering the basics, formulas, and advanced techniques.
Understanding Percentage Increase
A percentage increase is a measure of the change in value of a quantity over a given period of time. It’s calculated by dividing the difference between the new and old values by the old value, and then multiplying by 100. For example, if a product’s price increases from $10 to $12, the percentage increase is (2/10) x 100 = 20%. This means the price has increased by 20%.
Percentage increase is an important concept in finance, economics, and many other fields. It helps us understand the impact of changes in data on our business, investments, or personal finances. By calculating percentage increase, we can identify trends, make informed decisions, and optimize our strategies.
Basic Formula for Percentage Increase
The basic formula for percentage increase is:
| Formula | Description |
|---|---|
| =(New Value – Old Value) / Old Value | This formula calculates the difference between the new and old values, and then divides it by the old value. |
| =(New Value – Old Value) / Old Value x 100 | This formula multiplies the result by 100 to convert it to a percentage. |
For example, if the old value is $10 and the new value is $12, the percentage increase is:
=(12 – 10) / 10 = 0.2
=(12 – 10) / 10 x 100 = 20%
Using Google Sheets to Calculate Percentage Increase
Google Sheets makes it easy to calculate percentage increase using formulas and functions. Here are the steps:
- Enter the old and new values in two adjacent cells.
- Enter the formula =(New Value – Old Value) / Old Value in a new cell.
- Press Enter to calculate the result.
- Enter the formula =(New Value – Old Value) / Old Value x 100 in a new cell to convert the result to a percentage.
- Press Enter to calculate the result.
For example, if the old value is in cell A1 and the new value is in cell A2, the formula to calculate the percentage increase would be:
=((A2 – A1) / A1) x 100 (See Also: How to Remove Borders in Google Sheets? Simplify Your Data)
Advanced Techniques for Calculating Percentage Increase
Google Sheets offers several advanced techniques for calculating percentage increase, including:
Using the Percentage Increase Function
The PERCENTAGE function in Google Sheets calculates the percentage increase between two values. The syntax is:
=PERCENTAGE(old_value, new_value)
For example, if the old value is $10 and the new value is $12, the percentage increase is:
=PERCENTAGE(10, 12) = 20%
Using the Percentage Change Function
The PERCENT_CHANGE function in Google Sheets calculates the percentage change between two values. The syntax is:
=PERCENT_CHANGE(old_value, new_value)
For example, if the old value is $10 and the new value is $12, the percentage change is: (See Also: How to Change Data Labels in Google Sheets? Easy Steps)
=PERCENT_CHANGE(10, 12) = 20%
Using Array Formulas
Array formulas in Google Sheets allow you to calculate percentage increase for multiple values at once. The syntax is:
=ArrayFormula((New Value – Old Value) / Old Value x 100)
For example, if the old values are in column A and the new values are in column B, the array formula to calculate the percentage increase would be:
=ArrayFormula((B1:B10 – A1:A10) / A1:A10 x 100)
Common Mistakes to Avoid
When calculating percentage increase in Google Sheets, it’s essential to avoid common mistakes, including:
- Forgetting to divide by the old value.
- Forgetting to multiply by 100 to convert the result to a percentage.
- Using the wrong formula or function.
- Not considering the order of operations.
Best Practices for Calculating Percentage Increase
To ensure accurate results when calculating percentage increase in Google Sheets, follow these best practices:
- Use the correct formula or function.

FAQs
How do I calculate percentage increase for multiple values in Google Sheets?
You can use array formulas to calculate percentage increase for multiple values in Google Sheets. The syntax is =ArrayFormula((New Value – Old Value) / Old Value x 100). For example, if the old values are in column A and the new values are in column B, the array formula to calculate the percentage increase would be =ArrayFormula((B1:B10 – A1:A10) / A1:A10 x 100).
What is the difference between percentage increase and percentage change?
Percentage increase and percentage change are both measures of change in value, but they are calculated differently. Percentage increase is calculated by dividing the difference between the new and old values by the old value, while percentage change is calculated by dividing the difference between the new and old values by the average of the old and new values.
How do I round results to the nearest whole number or decimal place in Google Sheets?
You can use the ROUND function in Google Sheets to round results to the nearest whole number or decimal place. The syntax is =ROUND(result, number of decimal places). For example, if you want to round a result to two decimal places, the formula would be =ROUND(result, 2).
Can I use Google Sheets to calculate percentage increase for dates?
Yes, you can use Google Sheets to calculate percentage increase for dates. You can use the DATE function to calculate the difference between two dates, and then use the formula =(New Date – Old Date) / Old Date x 100 to calculate the percentage increase.
How do I calculate percentage increase for a range of values in Google Sheets?
You can use the PERCENTAGE function in Google Sheets to calculate percentage increase for a range of values. The syntax is =PERCENTAGE(old_value, new_value). For example, if the old values are in column A and the new values are in column B, the formula to calculate the percentage increase would be =PERCENTAGE(A1:A10, B1:B10).
