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).

Worked Example:   Sum if greater than in Excel

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.

Worked Example:   Sum if less than in Excel

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
