Key Concepts

Compound Interest

Compound interest is the process by which interest is added to the principal of an investment so that the added interest also earns interest from that point on. The compound interest formula, A = P(1 + r/n)^(nt), expresses how the initial principal P grows over time, where r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years. This concept is foundational in finance as it demonstrates the exponential growth of investments over time.

Compounding Frequency

Compounding frequency refers to the number of times interest is applied to the principal per year. Common frequencies include annually, semiannually, quarterly, monthly, or continuously. Higher compounding frequencies can lead to a larger effective annual rate because interest is being calculated and added to the principal more often, thus earning interest on interest more frequently.

Nominal vs Effective Interest Rates

The nominal interest rate is the stated annual rate before taking the effects of compounding into account, while the effective interest rate reflects the actual growth of the investment after compounding. Using the compound interest formulas allows one to convert a nominal rate compounded at a given frequency into the effective rate, which is critical when comparing investments that compound at different frequencies.
