Time Value of Money Formulas Future Value

How much is the present value worth in the future? FV=PresentValue(l+i)N where: FV is the value to be determined i is the interest rate and n is the number of time periods

Present Value

How much will a future value be worth in today's dollars? Present Value+FV/( I +i)n where: FV is the promised return on investment i is the interest rate and n is the number of time periods

Net Present Value

Finds the present value for each year the project has a return:

1. Each time period's promised return is calculated into present value.

2. Sum all of the time period's present value.

3. Sutract the project's original investment from the sum.

4. An NPV greater than one is good, less than one is bad.

Figure B-1 PMPs and CAPMs should know these formulas for their exams.
