# FINANCE Program

A menu driven program for financial calculations. The user selects the item
to find, and the program asks for the information necessary to compute the
answer.

- Simple Interest - Can find the interest, the principal, the rate, or the
time.
- Compound Interest - Can find the amount, the principal, the periodic rate,
the number of periods, or the effective rate.
- Future Value - Can find the future value, the payment, the number of periods,
or the periodic rate
- Present Value - Can find the present value, the payment, the number of
periods, or the periodic rate

All rates with the exception of simple interest problems are periodic (not
nominal) rates and the time is given in periods (not years).

## Formulas

Simple Interest: I=PRT and A=P(1+rt)

Compound Interest: A=P(1+i)^{n}

Future Value: FV = PMT * ( (1+i)^{n} - 1) / i

Present Value: PV = PMT * ( 1- (1+i)^{-n} ) / i
