Continuous Compounding Interest : Continuous compound interest is the procedure of obtaining interest on top of interest in a monthly, quarterly and semiannual basis and the interest is obtained continuously.
Compounding reflects the effect of the return in the next period on the return from the previous period. For example, if an investor puts $1,000 in a 1-year certificate of deposit (CD) that pays an annual interest rate of 4%, paid quarterly, the CD would earn 1% interest per quarter on the account balance.
