How to Show a Month Over Month Number in a Report

How to Show a Month Over Month Number in a Report

Hello!

I am building a very specific report that requires me to show a calculated monthly number over the course of a contract term. 

Example: Contract term is 36 months @ $100 p/month. I need to show, on the report, that $100 each month until the end of the term.

Additionally, the payments I need to show that the payments don't start until 3 months after the contract sign date. 

I have tried several different variants of formulas with no success. I do have the delayed formula partially built: 

add_month("Closing Date",3)

But that only gets me a date, it doesn't add the monthly number to the delayed date. 


Any help would be greatly and forever appreciated!!

Thank you!!
