USD trade values supported
LC Issue Commission
Formula: tenor days = expiry date minus issue date. Charge factor = 1 full quarter when tenor is 1 to 90 days; after that, 1 + (tenor days - 90) / 90. Commission in USD = LC value x rate % x charge factor. Commission in BDT = USD commission x conversion rate.
LC Amendment Commission
Calculation logic: Existing LC value is charged only for the extension period beyond the first 90 days. Increased value is charged full first-quarter commission if the amendment date falls within the first 90 days, plus second-quarter per-day commission from day 91 to new expiry. If no second-quarter rate is entered, the first-quarter rate is used.
Margin rule: If LC is processed against 100% or above margin, commission must not exceed 0.25%.
Maturity Date Calculator
Calculation logic: First calculate base date + tenor days + buffer days. If the result falls on Friday, Saturday or a Bangladesh Bank holiday, international banking practice is to move the payment/maturity date to the next banking business day. Keep extra holidays updated when Bangladesh Bank announces changes.
UPAS Financing Cost
Formula: annual finance rate = SOFR rate + margin. Finance cost = USD amount x annual finance rate % x tenor days / day-count basis. Margin should not exceed 3%.
Export Bill Discounting
Formula: annual discount rate = SOFR rate + margin. Discount charge = bill amount x annual discount rate % x discount days / day-count basis. Net proceeds = bill amount - discount charge. Margin should not exceed 3%.
Overdue or Forced-Loan Interest
Formula: effective overdue rate = base annual rate + penal interest. Interest = principal x effective overdue rate % x overdue days / day-count basis. Penal interest ceiling is 0.50%.
Loan EMI and Amortization
Formula: EMI = P x r x (1 + r)^n / ((1 + r)^n - 1). Here P = loan amount, r = monthly rate, n = tenor in months.
