I'm trying to make a Google sheet for my savings account where my goal is to reach X money before X date and I have several fields for each month and a field to every month where I have the amount of money saved in that month.
So I would like to have a function, where I could see how many months is back to my goal day, and that should decrease numbers of months back, when I'm typing in how many money saved that month.
Could anybody help me with a function for that?
