## Applying EOMONTH formula in financial modeling

EOMONTH formula in financial modeling ensures precision when calculating the closing days of months, particularly in projected cash flow. Here’s how to use it step-by-step:

1. Choose a cell and type “`=EOMONTH(`” then select the cell that contains the starting date of the model.
2. Add a comma, then enter the month(s) from the start date when the calculation should stop. For example, if you want to calculate up to the end of the 12th month, you would enter “11” to add 11 months to the start date.
3. Add a comma, then enter “-1” to make sure the formula calculates the end of the month instead of the beginning.
4. Close the formula with “`).`” The final formula should look like “`=EOMONTH(date,start, -1)`“, with “date” being the cell containing the starting date.
5. Drag the formula throughout the table to calculate the end of each month of projected cash flow.
6. Use “SUM” to tally projected cash flow for each month.

When inputting the EOMONTH formula, ensure that the start date is consistent throughout the model. This formula eliminates any confusion regarding varying month-end dates that sometimes occur in projected cash flow.

Pro Tip: Use the “EDATE” formula to calculate the end of a specific number of months after a particular date. Together, EOMONTH and EDATE can help produce a precise financial model.
