Sum by week in Excel

by

This tutorial shows how to Sum by week in Excel using the example below;

Formula

=SUMIFS(value,date,">="&A1,date,"<"&A1+7)

Explanation

To sum by week, you can use a formula based on the SUMIFS function. In the example shown, the formula in F4 is:

=SUMIFS(amount,date,">="&E4,date,"<"&E4+7)

This formula uses the named ranges “amount” (C4:C21) and “date” (B4:B21).

How this formula works

The SUMIFS function can sum ranges based on multiple criteria.

In this problem, we configure SUMIFS to sum amounts by week using two criteria: (1) dates greater than or equal to the date in column E, (2) dates less than the date in column E plus 7 days:

=SUMIFS(amount,date,">="&E4,date,"<"&E4+7)

When this formula is copied down, SUMIFS generates a sum for each week.

The dates in column E are Mondays. The first date is hard-coded, and the rest of the Mondays are calculated with a simple formula:

=E4+7
