Simple interest is a type of interest calculated only on the initial principal amount.

• Simple interest is calculated as: I = P * r * t, where I is the interest, P is the principal amount, r is the interest rate, and t is the time period.

• It is different from compound interest, which includes interest on both the principal amount and any accumulated interest.

• Simple interest is commonly used in loans, mortgages, and saving...read more

Compound interest is interest calculated on the initial principal and also on the accumulated interest from previous periods.

• Compound interest is calculated based on the initial principal amount and the accumulated interest from previous periods.

• The formula for compound interest is A = P(1 + r/n)^(nt), where A is the amount, P is the principal, r is the annual interest rate, n is the number of times interest is compoun...read more
