### Applications of the compound interest formula

Applications of the compound interest formula Quite often, three of the variables used in the compound interest formula are known and the fourth needs to be found. Finding P Finding i (interest rate per period) Aunt Freda leaves Thelma a legacy some deposit stock that was invested for ten years at 11% p.a. compounded quarterly.

### Compound Interest

The rate at which compound interest accrues depends on the frequency of compounding, such that the higher the number of compounding periods, the greater the compound interest. Thus, the amount of compound interest accrued on \$100 compounded at 10% annually will be lower than that on \$100 compounded at 5% semi-annually over the same time period.

### SESSION 4: INTEREST

i = interest rate being used for the payment interval. n = the number of compound periods over the term of the loan/investment. Note: When interest is compounded more than once a year (annually) you first have to calculate i and n in the following way: Where interest is calculated bi-annually i = rate ÷ 2 and n = no of years x 2

Compound Interest Formula. First we need to derive the Compound Interest Formula, which is (1) FV = PV(1 + i)N, where FV is the future value, PV is the present value, i is the interest rate per compounding period, and N is the number of compounding periods. We are using the terminology in the TI83 and TI84 manuals.
