Detailed explanation-3: -Compound interest, can be calculated using the formula FV = P*(1+R/N)^(N*T), where FV is the future value of the loan or investment, P is the initial principal amount, R is the annual interest rate, N represents the number of times interest is compounded per year, and T represents time in years.

Detailed explanation-4: -Simply divide your APY by 12 (for each month of the year) to find the percent interest your account earns per month. For example: A 12% APY would give you a 1% monthly interest rate (12 divided by 12 is 1). A 1% APY would give you a 0.083% monthly interest rate (1 divided by 12 is 0.083).
