Detailed explanation2: With compound interest, the interest per period is based on the principal balance plus any outstanding interest already accrued. Interest compounds over time. When calculating compound interest, the number of compounding periods makes a significant difference.
Detailed explanation3: Compound interest applies the interest rate to both the principal balance and accrued interest. In other words, it charges interest on interest.
