1. What is the Short Borrowing Fee?

The Short Borrowing Fee (SBF) is the cost incurred when borrowing stocks to sell short. It represents the interest charged by the lender for the borrowed securities and is calculated based on the borrow rate, stock value, and duration of the loan.

2. How Does the Calculator Work?

The calculator uses the Short Borrowing Fee formula:

\[ SBF = \frac{(BR \times SV \times D)}{365} \]

Where:

$ BR $ — Borrow Rate (%)
$ SV $ — Stock Value ($)
$ D $ — Days the stock is borrowed

Explanation: The formula calculates the daily borrowing cost by multiplying the borrow rate by the stock value, then multiplies by the number of days, and divides by 365 to annualize the calculation.

Details: Accurate calculation of short borrowing fees is crucial for short sellers to understand their total cost of borrowing, assess the profitability of short positions, and manage risk effectively.

4. Using the Calculator
