Key Concepts

Continuous Compounding

Continuous compounding is the limit of the compounding process as the number of compounding periods approaches infinity. Instead of discrete intervals, interest is accrued constantly, and the growth of the investment is modeled by an exponential function. This method provides the theoretical maximum yield for a given interest rate and time period.

Simple Interest

Simple interest is calculated solely on the original principal amount and does not consider any interest that has been previously earned. It uses a linear formula where the total interest is the product of the principal, rate, and time, making it straightforward but typically less beneficial over longer periods compared to compounded interest.

Compound Interest

Compound interest is the process by which interest is calculated on both the initial principal and the accumulated interest from previous periods. This leads to exponential growth of the investment as each period’s interest becomes part of the principal for the next, highlighting the reinvestment advantage over simple interest methods.

Compounding Frequency

Compounding frequency refers to how often interest is added to the principal during the investment period. Common frequencies include semiannual, quarterly, and daily compounding. A higher compounding frequency results in interest being calculated on the accrued interest more frequently, which generally increases the overall return compared to less frequent compounding.
