How to sum numbers until a certain value is reached in adjacent cell in Excel?
To sum a range of data in Excel is very easy for you, but have you known how to sum all data until a certain value is reached in adjacent cell? For example, there is a range of data, Row 1 includes years, Row 2 includes data values, and you want to sum all values in Row 2 until the corresponding cell in Row 1 is reached 2014 as shown as below screenshot.
Here I introduce a formula for you to quickly sum numbers until a value reached in adjacent cell.
Select a blank cell which will place the result, B4 for instance, and enter this formula =SUMIF($B$1:$Q$2,"<= 2014",$B$2:$Q$2) and press Enter key to show the summing result. See screenshot:
In the formula, B1:Q2 is the data range, and 2014 is the value you want to reach, you can change them as you need.
