## Even Cash Flow Calculator

This worksheet just might make calculating things like loan payments, the amount that could be borrowed, the interest rate, etc. a little easier than the HP-12C calculator, with Reverse Polish Notation, you have been holding onto for the last 30 years. Their are five inputs to the calculator: Rate Cash Flow (Payment) Number of Cash Flows Present […]
