Recap: Future Values
We know that FV = PV x (1+r)t
(1+r)t is called the future value factor
How to calculate?
◦ Calculator
◦ Tables
Future value more significant over longer periods where more interest compounded.

Recap: Present Values
Present Value = the current value of future cash flows discounted at an appropriate interest rate.
1/ (1+r)t is known as discount factor.
PV= FV x Discount Factor
Present value more insignificant over longer periods. Less money needed to accumulate big interest.

Tables
Table A1- future value factor for one unit of currency compounded at rate r for t (Page 784 of the textbook)
Table A2- present value factor for one unit of currency compounded at rate r for t periods (Page
785 of the textbook)
How to read the tables: The number of time periods are listed on the left hand side and the rate on the top.
