#### Formula
Compound Accrued Amount: A = P × (1 + r/n)n×t
Where: • P = Base penalty / fine amount ($) • r = Annual penalty interest rate (decimal) • n = Compounding frequency per year (e.g., 365 = daily) • t = Time in years = Days Overdue ÷ 365
Interest Charge = A − P
Subtotal = A + Surcharge
Reduction Amount = (Interest Charge + Surcharge) × (Reduction% ÷ 100)
Total Due = Subtotal − Reduction Amount
Simple Interest (Reference): I = P × (r ÷ 365) × Days
