Final answer:
To calculate days overdue in Excel, use the formula =IF(F6>30, B3-E6, "0") in cell G6 and fill down to G7:G15. The formula checks if the invoice age is over 30 days and calculates the difference between the current date and due date, otherwise displays 0.
Step-by-step explanation:
In cell G6, to calculate the number of days an invoice is overdue in Microsoft Excel, you can use an IF function combined with absolute cell referencing. Write the following formula in cell G6:
=IF(F6>30, B3-E6, "0")
This formula checks if the age of the invoice in cell F6 is greater than 30 days. If it is, it calculates the difference between the current date in cell B3 and the due date in cell E6. Otherwise, it displays 0, indicating that the invoice is not overdue. Make sure to use an absolute reference for cell B3 (e.g., $B$3) to keep this cell constant when using the Fill Handle. After entering the formula in G6, drag the cell's corner down to fill the cells G7:G15 with this formula without altering the reference to cell B3.
