This appendix contains two tables providing present and future value calculations for interest rates between 1-30% per year over periods of 1-20 years. Table 1 gives the present value (PV) of receiving $1 in the future, calculated as 1/(1+r)^t. Table 2 gives the future value (FV) of $1 today, calculated as (1+r)^t. For example, at a 10% interest rate, the PV of receiving $1 five years from now is $0.621, and the FV of $1 today five years from now is $1.611. The tables allow users to look up compound interest calculations for various time periods and rates.
