Explanation Given information: An investment with principal $ 12 , 450 is made for 10 years at 2.6 % compounded annually. Formula used: Compounding period can be defined as the duration or length of time from one interest payment to the next. If an investment made for 4 years at 6 % compounded annually (once per year) then it would have four compounding period which can be calculated by formula given below: Compounding periods = Term of investments ( years ) × m Here, m is the period per year. The interest rate per period can be calculated by dividing the annual, or nominal, rate by the number of periods per year, Interest rate per period = Nominal rate Period per year The compound amount (Future value) can be calculated by the formula given below: A = P × ( 1 + i ) n Here, P is the principal, i is the rate per period and n is the compounding period. The compound interest can be calculated by the formula given below: Compound interest = Compound amount − Principal Calculation: Consider the investment with principal $ 12 , 450 is made for 10 years at 2.6 % compounded annually and solve as shown below: Since, the variables-principal, time period (years), nominal rate and interest compounded are given; therefore, the compounding period can be calculated as below: Compounding periods ( n ) = Term of investments ( years ) × m = 10 × 1 ( In annually compounding, m = 1 ) = 10 Calculate the interest rate per period as below: Interest rate per period = Nominal rate Period per year ( m ) = 2
