Banker's discount calculates the discount deducted when a bill or note is purchased before maturity.
Banker’s Discount refers to the amount calculated by a bank when purchasing a bill of exchange before its maturity. It represents the interest deducted in advance by the bank for providing immediate cash against the future payment of the bill.
This is a reduction given by a seller to a buyer on the listed price of goods or services, often used to promote business relationships.
Offered to buyers for early payment, this encourages prompt settlement of invoices.
Specific to the banking industry, it is the discount calculated when banks purchase bills of exchange before their maturity.
The formula to calculate the banker’s discount is:
Where:
Suppose a bill of exchange has a face value of $10,000, a discount rate of 5% per annum, and is due to mature in 90 days.
Using the formula:
The banker’s discount would be $123.30.
