The Bybit Calculator serves as a valuable tool for traders, enabling users to refine their trading strategies based on accurate calculations. The calculator considers crucial factors such as Position Margin, Leverage, Average Entry/Exit Price, and Contract Quantity. Through this, traders can precisely compute Profit/Loss, Target Price, Liquidation Price, and Entry Price.
Here is a guide that outlines the correct logic for effectively harnessing the Bybit Calculator for enhanced decisionmaking in Perpetual and Futures contracts trading.
Step 1: Locate the Bybit Calculator at the top right of the Order Zone:
Step 2: Utilize the Calculator to choose from the following calculations:
Please note that trading fees and funding fees are not included in the calculations.
(1) Profit/Loss
Profit/Loss calculation involves determining the position's profit and loss, excluding fees.
You can calculate the Initial Margin, Profit/Loss, Profit/Loss (%), and ROI (Return of Investment) for your position by entering its Leverage, Contract Quantity, Entry price, and Close price.

Initial Margin: The required order cost when opening the position

Profit/Loss: Profit and loss of the position, excluding fees

Profit/Loss (%): Percentage of profit compared to the average entry price of the position

ROI: The ratio of return on assets to the initial margin used in the position. Formula: ROI = P&L / Initial Margin
For more details on the initial margin and profit and loss calculations, please refer to the following articles:
Example
Assuming Trader A buys the Perpetual Contracts with the following parameters:

Direction: Buy Long

Leverage: 10x

Quantity (Qty): 2

Entry Price: $36,000

Close Price: $40,000
Please note that the contract quantity and average entry price of the existing position can be viewed above the respective trading pair, adjacent to the quantity and entry price fields.
(2) Target Price
Determine the estimated target price to close the position by calculating the rate of return on investment (ROI %) needed, excluding fees.
Example
Assuming Trader A buys the Perpetual Contracts with the following parameters:

Direction: Buy Long

Leverage: 10x

Quantity (Qty): 1

Entry Price: $30,000

ROI (%): 29
Entering the value above, we can calculate that for the position to reach a 29% ROI, the targeted take profit/exit price should be set at around 7,280 USDT.
Please note that the contract quantity and average entry price of the existing position can be viewed above the respective trading pair, adjacent to the quantity and entry price fields.
(3) Liquidation Price
The Liquidation Price's calculation varies between the Isolated Margin mode and the Cross Margin mode. For detailed information, please refer to the content below.
Liquidation Price (Isolated Margin): Calculate the liquidation price while being in Isolated Margin mode.
Example
Assume Trader A buys the Perpetual Contracts with the following parameters:

Direction: Buy Long

Leverage: 10x

Quantity (Qty): 1000

Entry Price: $7,000
Upon entering the set of values in the calculator, the Liquidation Price is displayed as 6,335.00 USDT.
Liquidation Price (Cross Margin): Calculate the Liquidation Price while being on Cross Margin mode.
Under Cross Margin mode, the liquidation price is calculated based on the entire available margin in the account. Traders need to input their available balance in the respective coin type for the calculation.
Example
Assume Trader B buys the Perpetual Contracts with the following parameters:

Direction: Buy Long 10x

Available Balance: $100

Quantity (Qty): 1

Entry Price: $7,000
Upon entering the set of values in the calculator, the Liquidation Price is displyed as 6,942.64 USDT.

(4) Entry Price
Calculate your average entry price for multiple opening orders.
With these calculation tools, you can easily check the Average Entry Price for your positions. This capability empowers you to make more informed estimates, particularly in assessing the Profit and Loss for your positions.
Example
The current position of Trader A was opened with the following 3 orders:

Buy Long, Qty: 1, Entry Price: $7,000

Buy Long, Qty: 0.2, Entry Price: $7,500

Buy Long, Qty: 0.15, Entry Price: $6,900
Upon entering the set of values in the calculator the Average Entry Price is displayed as 7,062.90 USDT.
