# How to Calculate the Sum by Week in Excel

We can now use a formula based on the excel SUMIFS function to sum by week. This article provides a clear guide on how you can use the function to sum by week. Figure 1: How to sum by week

## General syntax of the formula

`=SUMIFS(value, date, “>=”&A1, date, “<”&A1+7)`

Where;

Value- refers to what you want to sum

Date- refers to the dates of the week for which you want to sum

## Understanding the formula

The SUMIFS function plays a critical role when it comes to summing values by week.

In our example above, we have found the sum of the payments by week.

To do this, all we need to do is specify the formula and it will help us sum by week

## How the formula works

• We can use the SUMIFS function to sum ranges based on multiple criteria
• In our case here, we want the SUMIFS function to sum amounts based on two criteria which are;
1. dates that are equal or greater than date in column D.
2. dates that are equal to or less than those in column D plus 7 days
• After we have found the sum for the first column, we need to copy down the formula to the other cells to get the sums for the other entries.

## Example Figure 2: Example of how to sum by week

In this example, we want to find the sum of all the payments. To do this, proceed as follows;

Step 1: fill the table with the data

Step 2: Indicate where you want the results to appear, in our case, the results should appear in column G.

Step 3: In cell G6, put the formula; `=SUMIFS(D5:D11,C5:C11,">="&F6,C5:C11,"<"&F6+7)`

Step 4: Press Enter to get the sum based on that week

Step 5: Copy down the formula to the other cells and get the sum based on their respective weeks

Solution examples I am trying to utilize a complicated sumif or sumifs formula that can pull a total amount from a date and a drop down box from another tab.
Solved by E. B. in 15 mins I have a spreadsheet that totals invoices. A bunch of cells at the bottom of the spreadsheet calculates totals based on which department the invoice is charged to. I'd like to add a function where it also considers the date (so if it's an invoice in January, it goes to a January total, February, etc.). But I can't figure out how to write it properly...
Solved by K. J. in 27 mins If I want to write a formula that states" "If this name shows up K24, and this word shows up in J24 pull this number from M24" I can creat that formula - however I need to drag this down so it pulls from row 24 - 60 - is there way to do this?
Solved by F. D. in 40 mins amending a formula so that there is another criteria and if it does not meet this criteria then we stick with the original criteria
Solved by A. B. in 40 mins So im trying to use a sumif formula, but i need it to not look for a range for one specific criteria but instead look for what one specific field says. Example Below =sum(sumifs(QuantityMC,TeamsMC,A6,TypeMC,B2)) The above formula works as on the specific MC sheet an entire column is dedicated for "TypeMC". I want to be able to delete this column and have "TypeMC" to be a single field as it will be the same for every item on that sheet but may differ on a different sheet.
