Using EOMONTH Function with Practical Example & Scenarios
This function has practical benefits in various department like HR Payroll, Loan Dues, Financial Reports, Deadline Calculations, etc. To understand this function in a better way, let us discuss several practical scenarios with examples.
Example 1: Calculating Salary Payment Date
In this scenario, an employee gave his resignation and the month end will be his last date of working, and the salary will be calculated based on that. Instead of checking up the calendar manually, we can automate it using the EOMONTH Function in the Excel.
- The Employee’s notice period starts from March 01, 2025. Hence, to calculate the last day of the month, we can use the following EOMONTH Function.
=EOMONTH("01-Mar-2025", 0)- The output will be 31st March 2025, as it is the last day of the current month.
Example 2: Bank Calculating Loan Dues
A Cooperative Bank is issuing a 14 month for a farmer. The loan start on March 10, 2025. Now, the Bank has to calculate the last day of the month after 14 months. They can simply use the EOMONTH Function in the Excel.
=EOMONTH("10-Mar-2025", 14)- The output will be 31st May 2026. So, May 31st, 2026 is the last day of the month from 14 months from the specified date. The loan gets completed.
Example 3: A GPU Company trying to find the last day of the previous Quarter
A GPU Production company wants to review sales data at the end of every quarter. Considering today as March 17, 2025, the company wants to check the last day of the previous quarter that is Q4 of 2024.
- Instead of using the date, let’s use TODAY Function, as today is March 17, 2025.
=EOMONTH(TODAY(), -3)Note: The Negative sign in the Month Argument informs excel to calculate the previous value (backward value).
- The output will be 31-December-2024. This will be the last day of the previous quarter Q4.
Example 4: Finding the Last Friday of a Month (Advanced Usage)
You can easily find the last friday of the given input month using EOMONTH and WEEKDAY function. To do this you might need to use the below formula.
=EOMONTH(B4,0) - MOD(WEEKDAY(EOMONTH(B4,0)),7) - 1| Input Date | Last Friday | Formula Used to Calculate Last Friday from given date |
|---|---|---|
| 15-Jan-2023 | 27-Jan-2023 | =EOMONTH(B4,0) – MOD(WEEKDAY(EOMONTH(B4,0)),7) – 1 |
| 20-Feb-2023 | 24-Feb-2023 | =EOMONTH(B5,0) – MOD(WEEKDAY(EOMONTH(B5,0)),7) – 1 |
| 25-Mar-2023 | 31-Mar-2023 | =EOMONTH(B6,0) – MOD(WEEKDAY(EOMONTH(B6,0)),7) – 1 |
