Couple of things...When you say you want to calculate yearly expiration date, how do you want to calculate it? From what date? See if this helps.

Lets say you have a beginning date in cell A1. In cell B1, you can calculate the expiration date as 1 year from beginning date by formatting the cell as a date and using the formula:
=EDATE(A1,12)

In cell C1, you can calculate days left by formatting the date as a number with 0 decimal places and using the formula:
=B1-Now()

In cell D1, you can get a warning message by using the formula:
=IF(C1>=0,"OK","Warning - Time to Renew")

Hope that helps you get started.
