Six Functions of a $1 is a suite of financial calculations commonly used in finance, economics, investment analysis, and valuation. These functions are especially useful to students learning about time value of money concepts.
Key input variables are amount, annual interest rate, and term or length of time.
The term and the frequency of compounding or discounting can be set to monthly, quarterly, or annual intervals.
Once a computation has been performed for a particular term, you can access a "periodic table" that displays the calculated results for all periods up to the term so you can see how the results will vary over time.
Changes made to the variables for each function are saved for subsequent use, thereby simplifying the task of making changes to some variables while retaining others. This helps with repetitive computations where you are examining the consequence of changing one variable at a time.
