‘Quick Internal Rate of Return’ offers a fast and easy way to compute the IRR of a stream of annual amounts usually starting with an investment treated as a negative amount. The unique data entry GUI employing sliders and buttons improves upon the more typical keypad pad mechanism.

However, there is a keypad data entry option that allows for numbers greater than +1000 and less than -1000, including number with two decimal place accuracy.

Internal rate of return can be computed over 1 to 12 years for the quick slider input option and over 1 to 20 years for the extended keypad input option.

Although periodic amounts are shown as yearly amounts, the user may interpret these as generic periodic amounts. For example, each amount could be considered a quarterly amount and the IRR computed would be interpreted as the return based on that frequency as well.
