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.
For any given interest rate and compounding frequency, an equivalent rate for any different compounding frequency exists. Compound interest may be contrasted with simple interest, where interest is not added to the principal (there is no compounding). Compound interest is standard in finance and economics, and simple interest is used infrequently (although certain financial products may contain elements of simple interest).
