Our company rents musical instruments to school children. There are two types of rentals - beginning rental instruments, and advancing rental instruments. There are two types of beginning rentals - we call them Starter Packs and Intro Offers. The data in the sample of our table below should help us break these down.
Table name - 'Rental Accounts - scrental'
| Contract Date | 1st Pmt Due Date | Down Payment |
| 8/12/2013 | 10/12/2013 | 17.12 |
| 9/1/2016 | 10/1/2016 | 0 |
| 7/2/2014 | 9/2/2014 | 17.16 |
| 8/29/2015 | 9/29/2015 | 0 |
| 12/2/2013 | 1/2/2014 | 178.04 |
If there is no down payment, it is a Beginner Rental - Starter Pack. Above, there are 2.
If there is a down payment with a 2 month interval between the Contract Date and 1st Pmt Due Date, it is a Beginner Rental - Intro Offer. Above, there are 2.
If there is a down payment and a 1 month interval between the Contract Date and 1st Pmt Due Date, it is an Advancing Rental. Above, there is 1.
What formula(s) should I use to make this happen? I want to be able to ask these questions:
- How many rentals are Beginner Rentals and how many are Advancing rentals?
- Of the Beginning Rentals, how many are Starter Packs and how many are Intro Offers?
Thanks for your help!
