Key Events

Formula for Banker’s Discount

The formula to calculate the banker’s discount is:

$$ \text{Banker's Discount (BD)} = \frac{P \times R \times T}{100} $$

Where:

  • \( P \) is the face value of the bill.
  • \( R \) is the rate of discount per annum.
  • \( T \) is the time to maturity in years.

Example Calculation

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.

$$ T = \frac{90}{365} = 0.2466 $$

Using the formula:

$$ BD = \frac{10000 \times 5 \times 0.2466}{100} = \frac{12330}{100} = \$123.30 $$

The banker’s discount would be $123.30.
