10 Amazing Excel Tricks To Sum Based On Month

When working with data in Excel, particularly with financial records, sales figures, or any time-series data, being able to sum values based on specific months can save you a lot of time and increase your productivity. In this guide, we're going to explore 10 amazing tricks that will help you sum data in Excel based on the month. 💡

From basic functions to advanced techniques, you’ll learn how to manipulate your data in a way that makes reporting easy and efficient. Let’s dive in!

1. Using the SUMIFS Function

The SUMIFS function is perfect for summing values based on multiple criteria, including dates. Here's how you can use it to sum values from a specific month:

=SUMIFS(sum_range, criteria_range1, criteria1, criteria_range2, criteria2)

• sum_range: The range you want to sum.
• criteria_range1: The range that contains dates.
• criteria1: The specific month you're targeting (like ">=01/01/2023" and "<=01/31/2023").

Example:

If you have sales data from A2 to A100 and dates from B2 to B100, you could sum January 2023 sales like this:

=SUMIFS(A2:A100, B2:B100, ">=01/01/2023", B2:B100, "<=01/31/2023")

Important Note: When using dates, it's crucial to keep the format consistent. Excel understands dates based on your locale settings.

2. Creating a Month Column

Instead of repeatedly referencing date criteria, you can add a helper column to extract months from dates:

=TEXT(B2, "mmmm")  // Will display full month names
=TEXT(B2, "mmm")   // Will display abbreviated month names

Once you have a month column, you can easily use the SUMIF function:

=SUMIF(month_range, "January", sum_range)

3. Using Pivot Tables

Pivot tables are a powerful feature for summarizing data in Excel. Here’s how to summarize sales by month:

1. Select your data range and go to Insert > PivotTable.
2. Drag the date field into the Rows area.
3. Right-click on any date in the Pivot Table and select Group. Choose Months.
4. Drag your sales field into the Values area.

Important Note: Pivot tables automatically group dates, making your life a lot easier!

4. Using Array Formulas

With Excel’s array formulas, you can sum data by month using a formula like this:

=SUM((MONTH(B2:B100)=1)*(A2:A100))

This formula sums values from A2 to A100 where the corresponding month in B2 to B100 is January (1).

Important Tips:

• After typing the formula, confirm with Ctrl+Shift+Enter (CSE) instead of just Enter.
• Excel will add curly braces {} around the formula, indicating it's an array formula.

5. The EOMONTH Function

To simplify summing monthly data, the EOMONTH function can be extremely useful:

=SUMIFS(A2:A100, B2:B100, ">=" & EOMONTH(TODAY(), -1) + 1, B2:B100, "<=" & EOMONTH(TODAY(), 0))

This sums up values from the last month automatically, so you don’t have to manually enter dates.

6. SUMPRODUCT for Flexible Criteria

SUMPRODUCT can also be useful for summing based on months without requiring an array formula. Here’s how to do it:

=SUMPRODUCT((MONTH(B2:B100)=1)*(A2:A100))

This works similarly to the array formula but does not require the special entry method.

7. Grouping Dates Manually

If you prefer manual grouping, you can create a summarized table:

1. List unique months in a separate range.
2. Use the SUMIF formula to sum sales for each month by referencing that unique month list.

Example:

=SUMIF(month_column, "January", sales_column)

8. Leveraging the FILTER Function (Excel 365)

For users with Excel 365, the FILTER function provides a straightforward way to sum values based on months:

=SUM(FILTER(A2:A100, MONTH(B2:B100)=1))

This will sum all values in A2:A100 where the month in B2:B100 is January.

9. Summing Multiple Months

If you need to sum multiple months at once, you can use SUMIFS with an array:

=SUM(SUMIFS(A2:A100, B2:B100, {"January", "February"}))

This will give you the total for both January and February.

10. Creating Dynamic Month Lists

You can create a dynamic list of months for reporting by using:

=TEXT(EDATE(TODAY(), ROW(A1)-1), "mmmm")

Drag this formula down to list each month for easy referencing in your SUMIF or SUMIFS formulas.

Conclusion

In this guide, we've explored 10 amazing tricks to sum data based on the month in Excel. From leveraging functions like SUMIFS, SUMPRODUCT, and FILTER to using Pivot Tables and dynamic lists, each method is designed to make your work easier and more efficient.
