In this video, we'll look at how to calculate and highlight expiration dates.
Let's say your company has started a membership program of some kind and your boss just sent you a set of data. She's given you a list of 1000 people that have renewed a membership in the last year or so, and she's looking for several things.
First, she wants you to calculate an expiration date one year in the future, on the last day of the same month the membership was renewed.
Second, she wants to see how many days remain before expiration.
Third, she wants to see a status of "Expired" for any memberships already expired, and "Expiring soon" for any memberships expiring in the next 30 days.
Finally, she said it would be nice to see expired members highlighted in pink, and those expiring soon highlighted in yellow.
Also - can she have it before her lunch meeting at noon?
First, let's convert this data to a proper Excel Table. This will make formulas much easier to enter, since Excel will automatically copy them down, as we go.
Now let's calculate the expiration dates. These are supposed to be at the end of the same month one year later, but let's just use a simple hack first, to get in the ballpark. As you've seen in earlier videos, dates are just serial numbers, so we can just enter a formula that adds 365 days to the Renewed date.
This is a good start. We can finish roughing out the solution and come back to fix this later.
When you're solving a more complex problem in Excel it's a good idea to validate the overall approach, then come back to the details at the end. You don't want to get stuck on a small thing right at the start, especially if the approach may change.
Now that we have an expiration date, we can now calculate days left. This needs update automatically in the future, so we'll use the TODAY function, which always returns todays date.
The formula is simply E5 minus TODAY(). When I hit return, we get days remaining before expiration. Negative numbers indicate a membership already expired.
For status, we'll use a simple nested IF formula. If days left is less than zero, the membership is expired. Otherwise, if days left is less than 30, the status should be "Expiring soon". Otherwise, the status is nothing.
The Excel TODAY function returns the current date, updated continuously when a worksheet is changed or opened. The TODAY function takes no arguments. You can format the value returned by TODAY using any standard date format. If you need current...
The IF function runs a logical test and returns one value for a TRUE result, and another for a FALSE result. For example, to "pass" scores above 70: =IF(A1>70,"Pass","Fail"). More than one condition can be tested by nesting IF functions. The IF...
The Excel EOMONTH function returns the last day of the month, n months in the past or future. You can use EDATE to calculate expiration dates, due dates, and other dates that need to land on the last day of a month. Use a positive value for...
