Key Concepts

Compound Interest

Compound interest is the method of calculating interest whereby interest earned is added to the principal, so that from that moment on, interest is earned on the new, larger principal amount. This concept is foundational for understanding how investments or loans grow over time when interest is reinvested rather than paid out.

Annual Compounding

Annual compounding is a specific case of compound interest where the interest is added to the principal once per year. It simplifies calculations and is a common assumption in many financial problems, illustrating how even small increases in the interest rate can significantly affect the growth of an investment over multiple years.

Exponential Equations in Finance

Exponential equations are used to model the growth of investments when compounded interest is involved. In these equations, the future value is expressed as the principal multiplied by a base raised to the power of the number of compounding periods, requiring techniques such as taking nth roots or logarithms to solve for unknown variables like the interest rate.
