Financiers and investors have developed several ways to measure the investment potential of an asset or business venture. One of the most popular measures is referred to as IRR or the internal rate of return. Every first-year finance student knows how to calculate the IRR on one of two financial calculators. While there are many different types of financial calculators, there are two that dominate the banking and financial world. They are the TI BA II financial calculator and the HP 10bII.
