F/P : Compound amount factor. Find F given P.
P/F : Present worth factor. Find P given F.
These kinds of tables for looking up compound interest for various factors are very commonly used in engineering economics.
Some definitions:​
i
= effective interest rate per unit period (normally one year)​
n
= number of interest periods​
P
= a present sum of money​
F
= a future sum of money equivalent to
P
but
n
interest periods from the present at interest rate
i
​​
A
= an end-of-period cash receipt or disbursement in a uniform series continuing for
n
periods with the entire series equivalent to
P
or
F
at interest rate
i
​​
G
= uniform period-by-period increase or decrease in cash receipts or disbursement; the arithmetic gradient
