What is the formula for calculating compound interest?
The mathematical formula for calculating compound interest, A=P(1+r/n)^nt, uses four simple numbers to allow you to see how much money plus interest you’ll have after the number of time periods, or compound periods. ‘A’ represents the accrued amount of your principal plus interest, which is the total.
How do you calculate compound interest years?
A = P(1 + r/n)nt
- A = Accrued amount (principal + interest)
- P = Principal amount.
- r = Annual nominal interest rate as a decimal.
- R = Annual nominal interest rate as a percent.
- r = R/100.
- n = number of compounding periods per unit of time.
- t = time in decimal years; e.g., 6 months is calculated as 0.5 years.

- Note: The above formula: A = CI + P will give us total amount.
- Questions 1:Find the amount if Rs 20000 is invested at 10% p.a. for 3 years.
- Solution: Using the formula:A= P [1+ R/100]n
- Question 2: Find the CI, if Rs 1000 was invested for 1.5 years at 20% p.a. compounded half yearly.
