Calculation Breakdown
Formula: Simple Interest (SI) = (P × R × T) / 100
Where P = Principal, R = Rate (% per year), T = Time in years.
Formula: Total Amount (A) = P × (1 + R/n)(n×T)
Compound Interest: CI = A − P
Where P = Principal, R = Rate (in decimal), n = Compounding periods per year, T = Time in years.
