What is Periodic Compound Interest?

Periodic compound interest is a method of calculating interest on a principal amount where the interest is added to the principal at regular intervals, such as monthly, quarterly, or annually. This is in contrast to simple interest, where interest is calculated only on the initial principal amount.

All Formulae Related to Periodic Compound Interest

1. Future Value (A) with periodic compound interest: A = P(1 + r/n)^(nt)Where:
• A represents the future value of the investment or loan.
• P is the principal amount (the initial amount of money).
• r is the annual interest rate (as a decimal).
• n is the number of times interest is compounded per year.
• t is the number of years the money is invested or borrowed for.
2. Compound Interest (CI) earned or paid: CI = A – PThis formula calculates the total interest earned or paid over the investment or loan term.
3. Principal (P) calculation: P = A / (1 + r/n)^(nt)You can use this formula to find the initial principal amount when you know the future value, interest rate, compounding frequency, and time.
4. Effective Annual Rate (EAR) formula: EAR = (1 + r/n)^n – 1The EAR represents the annualized interest rate, taking into account compounding over multiple periods per year. It is used to compare the true cost or return of different financial products.
