When it comes to data analysis and manipulation, Google Sheets is an incredibly powerful tool that offers a wide range of features and functions to help you get the most out of your data. One of the most useful and versatile functions in Google Sheets is the cumulative sum, also known as the running total or cumulative total. This function allows you to calculate the total of a series of numbers, adding each new value to the previous total to create a running total. In this blog post, we’ll explore how to do a cumulative sum in Google Sheets, including the different methods and formulas you can use to achieve this.
Why Use a Cumulative Sum in Google Sheets?
A cumulative sum is a powerful tool that can be used in a wide range of applications, from financial analysis to inventory management. By calculating the running total of a series of numbers, you can gain valuable insights into trends and patterns in your data, and make more informed decisions as a result. For example, if you’re tracking sales figures over time, a cumulative sum can help you identify trends and patterns in your sales data, such as seasonal fluctuations or changes in customer behavior.
In addition to its practical applications, the cumulative sum is also a useful tool for data visualization. By using a cumulative sum to calculate the running total of a series of numbers, you can create charts and graphs that show the accumulation of values over time, providing a clear and intuitive visual representation of your data.
Method 1: Using the SUMIF Function
One way to calculate a cumulative sum in Google Sheets is to use the SUMIF function. The SUMIF function allows you to sum a range of cells based on a specific condition, and can be used to calculate a cumulative sum by summing a range of cells and then adding the result to the previous total.
To use the SUMIF function to calculate a cumulative sum, follow these steps:
- Enter the formula =SUMIF(A:A, A1, B:B) in the cell where you want to display the cumulative sum.
- Replace A:A with the range of cells that contains the data you want to sum.
- Replace A1 with the cell that contains the condition you want to apply to the data.
- Replace B:B with the range of cells that contains the data you want to sum.
For example, if you want to calculate the cumulative sum of a series of sales figures, you could enter the formula =SUMIF(A:A, A1, B:B) in the cell where you want to display the cumulative sum, replacing A:A with the range of cells that contains the sales figures, A1 with the cell that contains the condition (e.g. “Sales > 100”), and B:B with the range of cells that contains the sales figures.
Method 2: Using the SUMIFS Function
Another way to calculate a cumulative sum in Google Sheets is to use the SUMIFS function. The SUMIFS function allows you to sum a range of cells based on multiple conditions, and can be used to calculate a cumulative sum by summing a range of cells and then adding the result to the previous total.

To use the SUMIFS function to calculate a cumulative sum, follow these steps:
- Enter the formula =SUMIFS(B:B, A:A, A1, C:C, D1) in the cell where you want to display the cumulative sum.
- Replace B:B with the range of cells that contains the data you want to sum.
- Replace A:A with the range of cells that contains the data you want to apply the condition to.
- Replace A1 with the cell that contains the first condition you want to apply.
- Replace C:C with the range of cells that contains the data you want to apply the second condition to.
- Replace D1 with the cell that contains the second condition you want to apply.
For example, if you want to calculate the cumulative sum of a series of sales figures based on multiple conditions (e.g. sales > 100 and region = “North”), you could enter the formula =SUMIFS(B:B, A:A, A1, C:C, D1) in the cell where you want to display the cumulative sum, replacing B:B with the range of cells that contains the sales figures, A:A with the range of cells that contains the data you want to apply the condition to, A1 with the cell that contains the first condition (e.g. “Sales > 100”), C:C with the range of cells that contains the data you want to apply the second condition to, and D1 with the cell that contains the second condition (e.g. “North”).
Method 3: Using the ArrayFormula
A third way to calculate a cumulative sum in Google Sheets is to use the ArrayFormula function. The ArrayFormula function allows you to apply a formula to an entire range of cells, and can be used to calculate a cumulative sum by summing a range of cells and then adding the result to the previous total.
To use the ArrayFormula function to calculate a cumulative sum, follow these steps:
- Enter the formula =ArrayFormula(SUM(B:B)) in the cell where you want to display the cumulative sum.
- Replace B:B with the range of cells that contains the data you want to sum.
For example, if you want to calculate the cumulative sum of a series of sales figures, you could enter the formula =ArrayFormula(SUM(B:B)) in the cell where you want to display the cumulative sum, replacing B:B with the range of cells that contains the sales figures.
Method 4: Using a Script
A fourth way to calculate a cumulative sum in Google Sheets is to use a script. The script can be used to calculate the cumulative sum of a series of numbers, and can be triggered by a button or a formula. (See Also: How to Search Keywords in Google Sheets? Master Your Data)
To use a script to calculate a cumulative sum, follow these steps:
- Open the script editor by clicking on the “Tools” menu and selecting “Script editor.”
- Enter the following script in the editor:
“`
function calculateCumulativeSum() {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getRange(“B:B”);
var values = range.getValues();
var cumulativeSum = 0;
for (var i = 0; i < values.length; i++) { cumulativeSum += values[i][0]; } sheet.getRange("A1").setValue(cumulativeSum); } ``` - Save the script by clicking on the “File” menu and selecting “Save.”
- Trigger the script by clicking on the “Run” button or by using a formula to trigger the script.
For example, if you want to calculate the cumulative sum of a series of sales figures, you could enter the formula =calculateCumulativeSum() in the cell where you want to display the cumulative sum, replacing “B:B” with the range of cells that contains the sales figures.
