What is a good program for handling complex financial/debt/payment equations?
I’m curious about a problem modeling complex interest payment plans, as you might have with one or several credit cards, each charging different interest rates, and sometimes with artificially complicated payment plans. I can sit down and do all the math, but I’m wondering if there isn’t a clean computer program or service to handle this problem in it’s full complexity, as you might have for a small business.
