Key Concepts

Continuous Compounding

Continuous compounding is a method of calculating interest where the frequency of compounding is increased to an infinite number of periods per year. Instead of interest being compounded at discrete intervals (such as monthly or annually), it is compounded continuously. This concept is essential for understanding how investments can grow over time when interest is added to the principal at every moment, and it is modeled using the exponential function.

Exponential Growth

Exponential growth refers to the process where the value of an investment increases at a rate proportional to its current size, leading to growth that accelerates over time. When applied to finance, exponential growth is observed in the context of continuously compounded interest, where the accumulated amount of an investment can be determined using an exponential function. This concept is fundamental for modeling how investments grow over long periods.

Time Value of Money

The time value of money is a financial principle that captures how the value of money changes over time due to the potential earning capacity of invested funds. This concept acknowledges that money available today can be invested to earn interest, thereby increasing in value over time. The time value of money is a key factor in evaluating investments and is mathematically represented through various compounding formulas, including continuous compounding.
