Answer:
Step-by-step explanation:
ollowing is the formula for calculating compound interest when time period is specified in years and interest rate in % per annum.
A = P(1+r/n)nt
CI = A-P
Where,
CI = Compounded interest
A = Final amount
P = Principal
t = Time period in years
n = Number of compounding periods per year
r = Interest rate
Calculation Examples
You can solve for any variable by rearranging the compound interest formula as illustrated in the following examples:-
1. What is the compound interest of 75000 at 7.9% per annum compounded semi-annually in 3 years?
Ans. A = P(1+r/n)nt = 75000(1 + (7.9 / 100) / 2)6 = 94625.51
Interest = 94625.51 - 75000 = 19625.51
