Learning Objectives
1. Explain the concept of the time value of money. (LO1)
2. Calculate present values, future values, and annuities based on the number of time periods involved and the going interest rate. (LO2)
3. Calculate yield based on the time relationships between cash flows. (LO3)

Future Value and Present Value
• Future Value (FV) is what money today will be worth at some point in the future.
• Present Value (PV) is what money at some point in the future is worth today.

Nominal and Effective Annual Interest Rates
• Interest is often compounded quarterly, monthly, or semiannually.
• Effective interest rate takes into account compounding.
• Effective Annual Interest Rate = (1 + i/m)m – 1 where i = nominal annual interest rate m = number of compounding periods
per year
LO2

Annuities
Annuity: a stream or series of equal payments to be received in the future.
• The payments are assumed to be received at the end of each period (unless stated otherwise).
• A good example of an annuity is a lease, where a fixed monthly charge is paid over a number of years.
