The factor (1+ rt)−1 in formula (3) is called a discount factor at a simple interest rate r and the process of calculating P from S is called discount-ing at a simple interest rate r, or simple discount at an interest rate r. We can display the relationship between P and S on a time diagram. P = S(1+ rt)−1.
1.6 Rate of Discount: d Definition – an effective rate of interest is taken as a percentage of the balance at the beginning of the year, while an effective rate of discount is at the end of the year. – eg. if 1 is invested and 6% interest is paid at the end of the year, then the Accumulated Value is 1.06

2.4.1 Simple Discount at an Interest Rate; 2.4.2 Simple Discount at a Discount Rate
discount rate. dt = a(t) a(t 1) a(t) a(t 1) = (1 dt)a(t) Mathematically, it is only necessary to use the interest rate, but in some cases it is more natural to use the discount rate. The discount rate d and interest rate i are related by: 1 d = v = 1 1 + i From this relationship, we can solve for d in terms of i and vice versa i = d 1 d d = i 1 + i
