Excel/Conditional formattin formula



Im trying to creat a spreadsheet that reminds me when my clients insurance policy will expire. For example, effective date is 3/29/14, and it will expire in 1 year. What formula can I use?

Thanks in advance,



I will assume you have a cell that indicates the expiration date of the policy.
For my example I will assume the cell is D7.
Using the conditional formatting/new rules/use a formula to determine which cells to format/ put in the following formula =-NOW()+D7-30<30.  Then select the format you want. then click ok.

If todays date is within 30 days of the expiration date the formula will result in TRUE.  And if the result is true the conditional formatting will format the cell to whatever format you have chosen,

Obviously you can change the formula to 45 days 60 days etc. etc.

Hope this helps
