Simple vs. Compound Interest

Understanding how interest works is fundamental to managing your finances, whether you're saving money or taking out a loan.

Simple Interest

Simple interest is calculated only on the principal amount of a loan or deposit.

Formula: I = P × r × t

Compound Interest

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

Formula: A = P(1 + r/n)^(nt)
