Short Stock Profit Calculator

The short stock profit calculator is a powerful tool that helps traders evaluate the profitability of short trades. By entering key trade data such as entry price, exit price, commissions, number of shares, days held, and the stock borrow rate, the calculator determines your net profit or loss, taking into account all associated costs.

The Short Stock Profit Calculator

Step-by-Step Explanation of The Short Stock Profit Calculator

Entry Price and Exit Price: The calculator starts by calculating the gross profit or loss from the trade. Since this is a short position, profit is generated when the stock price drops between the entry and exit.

Gross Profit/Loss Formula:

$$\text{Gross Profit/Loss} = (\text{Entry Price} – \text{Exit Price}) \times \text{Number of Shares}$$

This initial calculation shows how much was earned or lost based on the price change of the stock while the short position was held.

Commissions on Entry and Exit: The calculator deducts entry and exit commissions, which are fees charged by the broker to execute the trades. These are entered as percentages of the stock prices during both the entry and exit of the trade.

Total Commission Formula:

$$\text{Total Commission} = (\text{Entry Price} \times \text{Commission on Entry} \times \text{Number of Shares}) + (\text{Exit Price} \times \text{Commission on Exit} \times \text{Number of Shares})$$

Stock Borrow Rate: For short selling, there is an additional cost – the borrow rate – which is charged as an annual percentage for borrowing shares. The calculator factors in the stock borrow rate for the number of days the short position was held.

Borrow Cost Formula:

$$\text{Borrow Cost} = (\text{Entry Price} \times \text{Borrow Rate} \times \text{Number of Shares} \times \frac{\text{Days Held}}{365})$$

Net Profit/Loss: Finally, the short stock profit calculator subtracts the total commissions and the borrow cost from the gross profit to give the net profit or loss.

Net Profit/Loss Formula:

$$\text{Net Profit/Loss} = \text{Gross Profit/Loss} – \text{Total Commission} – \text{Borrow Cost}$$

Example of How The Short Stock Profit Calculator Works

Let’s say you shorted 100 shares of a stock at $50 per share, exited the trade at $45, held the position for 10 days, paid 0.5% commission on both entry and exit, and had a borrow rate of 2%. The short stock profit calculator would compute the gross profit first, subtract the commission fees, and factor in the borrow cost to give you the net profit or loss.

Importance of the Short Stock Profit Calculator

Using a short stock profit calculator is essential for short sellers to understand their true profits after accounting for commissions and borrowing costs. This ensures that traders don’t overlook hidden costs that can significantly affect profitability. Additionally, by incorporating the number of days held and the borrow rate, the calculator provides a more realistic view of the total cost of a short trade.
