Question details

The user needs to combine employee and pay-code columns to calculate the total overtime for each unique combination.

Product
Excel
Device & OS
not provided
Scenario
Summarizing employee payroll data to find the total overtime hours per employee and pay-code.
Observed behavior
The goal is to generate a consolidated list showing total overtime grouped by specific employee and pay-code combinations.
Before you start

Ensure your data has clear headers for the employee, pay-code, and overtime columns, and verify that the overtime values are formatted as numbers rather than text.

Solution 1Recommended

Use the GROUPBY Function to Summarize Data

The GROUPBY function is a quick, single-formula method to group data by multiple columns and aggregate totals instantly.

This modern dynamic array function simplifies the process by replacing complex formulas. Note that it is only available in the latest Microsoft 365 updates.

1
Enter the GROUPBY formula

Select a blank cell where you want the summary array to appear and type the formula =GROUPBY(A2:B25, C2:C25, SUM).

2
Adjust cell references

Change A2:B25 to match the actual range of your employee and pay-code columns, and C2:C25 to match your overtime column.

3
Press Enter to calculate

Press Enter to instantly generate a spilled array displaying unique combinations and their calculated total overtime values.

Version Compatibility: The GROUPBY function requires a newer version of Excel. If it results in a #NAME? error, use the PivotTable or SUMIFS solutions below.

Frequently Asked Questions

Why is my SUMIFS formula returning zero?

Your SUMIFS formula might return zero if the criteria ranges do not perfectly match the unique values. Check for leading or trailing spaces in your employee names or pay-codes, and ensure your overtime column contains numerical data.

Can I automatically sort the UNIQUE combinations?

Yes, you can wrap the UNIQUE function inside a SORT function, like =SORT(UNIQUE(A2:B100)), to automatically organize the extracted employee and pay-code combinations in ascending alphabetical order.

How do I dynamically update totals when new overtime data is added?

To ensure your formulas and PivotTables update automatically when new rows are added, convert your original dataset into an Excel Table by pressing Ctrl+T before applying formulas or inserting your PivotTable.

What should I do if the GROUPBY function is not available?

If your version of Excel does not support the GROUPBY function, you can use the PivotTable method or the combination of the UNIQUE and SUMIFS functions, which are widely supported in older Excel releases, to achieve the exact same result.
