Need help with a formula

Hi. I want to enter a formula that will return the average rent of all units leased within the last 3 months from latest lease and another that will return the average rent of all leases before those 3 monthsper unit type. Any advice? Thanks

There's probably more than 1 way to do it but here's my first thoughts:

- Use a Max function on the dates of the leased units and this will find the last leased unit

- In another cell you can use ="whatever cell you used for the max" - date(0,3,0) to get 3 months prior

-then you can do an averageifs function and have the criteria be greater than or equal to the lower end of that range and less than or equal to the upper end of that range and have the averaged range be the rent

From Chat GPT:

"Assuming that the data is stored in columns "A" through "C" with "A" being the date of lease, "B" being the unit number, and "C" being the rent amount, the formula to calculate the average rent of all units leased in the last three months would be:

=AVERAGEIFS(C:C,A:A,">" & MAX(A:A) - 90,A:A,"=" & MAX(A:A))

This formula uses the AVERAGEIFS function to calculate the average of all rent amounts (column C) where the date of lease (column A) is greater than the maximum date of lease minus 90 days, and the date of lease is less than or equal to the maximum date of lease."

 

Generally, yes. For the average rent of all units in the last 90 days, I'd use the =AVERAGEIF function to average the rent column if the date column is less than today's date minus 90 days. For the average rent for last 90 days for each unit type, I'd use the =AVERAGEIFS function to do the exact same as previously mentioned, but set up a table to include a separate logical function to determine if the the unit type from the raw data is equal to the table just set up.
