Hi,

I have an assignment to build a sql script for modeling purposes. The model is an amortization schedule of a car loan and has several different columns with calculations and 36 rows representing 3 years (3 X 12 months).
The challenge is to build the model in such a way that I can easily change the amortization period from 36 months into 18, 12, 24, etc. which will make the rest of the formulas on the other columns re-calculated for the new period.

Any suggestions on how can I approach this and build this model? What functions should I use?

thanks!

Have a "header" table with the basic loan information which is referenced by a "payments" table. The header has the number of payments and the payments use that value.
