How to Easily Sum Every N Cells in Google Sheets

Have you ever needed to sum a specific number of cells in Google Sheets? Whether it’s summing columns to the right or rows to the bottom, there’s an efficient way to do it. In this article, I’ll show you two key formulas that will make summing in Google Sheets a breeze.

Summing Every N Cells to the Right

Let’s start by summing every N cells to the right in Google Sheets. This technique requires the use of the SUM function combined with OFFSET and COLUMN. Here’s how it works:

1. Select the range of cells you want to sum.
2. In the formula bar, enter the following formula: =SUM(OFFSET($B$3, 0, (COLUMN() - COLUMN($B$3)) * N, 1, N)).
3. Replace N with the number of cells you want to sum.

For example, if you want to sum every 3 cells to the right, you would use the formula =SUM(OFFSET($B$3, 0, (COLUMN() - COLUMN($B$3)) * 3, 1, 3)).

Simply drag the formula to the right to sum the desired cells. The formula will automatically adjust the range based on the number of cells you specified.

Usage Note: If you insert this formula in any column other than B, make sure to change the cell reference within the formula COLUMN($B$3) to the corresponding column letter.

Summing Every N Cells to the Bottom

Now, let’s move on to summing every N cells to the bottom in Google Sheets. This method involves using the SUM function along with OFFSET and ROW. Follow these steps:

1. Select the range of cells you want to sum.
2. In the formula bar, enter the following formula: =SUM(OFFSET($D$2, (ROW() - ROW($D$2)) * N, 0, N, 1)).
3. Replace N with the number of cells you want to sum.

For instance, if you want to sum every 3 cells to the bottom, you would use the formula =SUM(OFFSET($D$2, (ROW() - ROW($D$2)) * 3, 0, 3, 1)).

Drag the formula down to sum the desired cells. The formula will adjust the range based on the number of cells specified.

Usage Note: If you insert this formula in any other row than H, modify the formula to (ROW() - ROW($D$5)) * N.

And there you have it – a simple way to sum every N cells to the right or bottom in Google Sheets. These formulas will save you time and effort when working with large sets of data.
