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 the yield based on the time relationships between cash flows. (LO3)

Why?because interest can be earned on the money
The connecting piece or link between present (today) and future is the interest or discount rate
Basic Idea: Money has different values at different points in time.

Capital Budgeting Decision and Cost of Capital
• Capital budgeting decision is about
comparing current outlays with future benefits:
• Cost of capital is the discount rate used in this comparison process.

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 in the real world.
• A nominal annual interest rate assumes annual compounding.
• It must be adjusted to reflect the more frequent than annual compounding.
• Effective Annual Interest Rate = (1 + i/m)m – 1 where i = nominal annual interest rate m = number of compounding periods per year

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.

Summary and Conclusions
• The financial manager uses the time value of money approach to value cash flows that occur at different points in time.
• A dollar invested today at compound interest will grow to a larger value in future. That future value, discounted at compound interest, is equated to a present value today.
• Cash values may be single amounts, or a series of equal amounts (annuity).
• Five variables are involved in a time value of money problem. The fifth variable can be determined if given the other four.
