Interest Calculator

Interest Calculator performs a number of interest related calculations. It calculates the present worth, future value, required interest rate and investment period of an investment, whether it is a single deposit, a number of equal deposits (Uniform Series), or a number of varying deposits (Arithmetic Gradient and Geometric Gradient series).
Each of these calculations can be performed based on simple interest, compound interest, or continuous compounding.
Also included are calculations for perpetuity determination and to calculate the effective annual interest rate.
This comes with a context sensitive help system which explains each calculation and provides comprehensive examples.
This is an excellent tool for students, individual investors or anyone involved in business or finance
