I am trying to convert an excel spread sheet I have kept for over 15 years of investments into google sheet, but I am getting a formula error on all purchases I have made that are less than 1 year old.
An example of a formula I am using is =RATE(G9/12,0,-1*F9,J9,0)
The numeric values of this formula would be =RATE(5.57/12,0,-6854,5672,0)
This should be showing me the APR based on the change so far this year, but instead I am getting the error "Function rate parameter 1 value is 0. It should be greater than 0."
Once my purchase is one year or more old, the formula works fine. How can I include the apr of a recent purchase?
