In simple interest, interest is calculated solely on the original principal sum. Accumulated interest is never added to the principal to generate subsequent returns.
Simple interest produces a fixed, linear monetary return every year: SI = (P × R × T) / 100. Because the earning base never changes, total interest accrued is directly proportional to elapsed time.
