How to Calculate Profit and Loss for Futures Contracts?
Profit and loss calculations are based on the contractās collateral. For instance, a USDā-margined contract will be denominated in USDT. Whereas, BTC Coin-margined contracts will be denominated in BTC.
Do note that unrealized Profit and Loss are calculated based on the Mark Price, while realized Profit and Loss are calculated based on the last price.
Profit and Loss calculations for Coin-margined contracts (BTCUSD)
A BTC coin-margined contract is denominated, collateralized and settled in Bitcoin, which means Bitcoin is used as the base currency. Each BTC coin-margined contract represents 100 USD and as such, USD is the counter currency. Since each contract represents a fixed quantity of USD, this means Bitcoin is used to fund the initial margin or calculate profit and loss.
Assume you purchased 100 Bitcoin-margined perpetual contracts (100 x 100 USD = $10,000) at $50,000 each. By doing this, you are essentially selling USD 10,000 and buying an equivalent value of Bitcoin (10,000/50,000 = 0.2 BTC).
Suppose Bitcoinās price rose to $55,000, and you want to secure profits from the trade. To close the position, you buy back USD 10,000 worth of contracts and simultaneously sell the equivalent of Bitcoin (10,000/55,000 = 0.1818 BTC).
In this trade, your profit will be calculated as such: Quantity of Bitcoins at Entry - Quantity of Bitcoins at Exit = 0.2 - 0.1818 = 0.0182 BTC.
In short, the profit and loss formula will be:
((1 / Futures Entry Price) - (1 / Futures Exit Price)) * Position Size
((1/50,000) - (1/55,000)) * (100 contracts x 100USD) = 0.0182 BTC
Example for short position:
Short BTCUSD 0925 Quarterly (Buy USD, Sell BTC):
((1 / Futures Entry Price) - (1 / Futures Exit Price)) * (Position Size * -1)
((1/50,000) - (1/45,500)) * (100 contracts x 100USD) = 0.0198 BTC
Profit and Loss calculations for USDā-margined contracts (BTC/USDT)
Assume you purchase (long) 10,000 USDT worth of BTC/USDT perpetual contracts at 50,000 USDT. The price increases and you exit at 55,000 USDT. Your profit will be:
((1 / Futures Entry Price) - (1 / Futures Exit Price)) * Position Size
(1 / 50,000 - 1 / 55,000) * 10,000 = 0.018182 Bitcoin
Conversion to USDT = 0.018182 * 55,000 USDT = 1,000 USDT
Assume you sold (short) 10,000 USDT worth of BTC/USDT perpetual contracts at 50,000 USDT. The price decreases and you exit at 45,000 USDT. Your profit will be:
((1 / Futures Entry Price) - (1 / Futures Exit Price)) * (Position Size * -1)
(1 / 50,000 - 1 / 45,000) * -10,000 = 0.022 Bitcoin
Conversion to USDT = 0.022 * 45,000 USDT = 1,000 USDT
How to calculate Unrealized P&L and ROE%
USDā-M Futures Contracts
Users choose Mark price as price basis:
Unrealized P&L = position size * direction of order * (mark price - entry price)
Users choose Latest price as price basis:
Unrealized P&L = position size * direction of order * (latest price - entry price)
Direction of order: 1 for long orderļ¼-1 for short order
The platform supports and adopts the latest price by default. No marked price is provided yet. The actual price shall be subject to the interface.
COIN-M Futures Contracts
Users choose Mark price as price basis:
Unrealized P&L = position_size * contract_multiplier * direction of order * (1 / entry price - 1 / mark price)
Users choose Latest price as price basis:
Unrealized P&L = position_size * contract_multiplier * direction of order * (1 / entry price - 1 / latest price)
The platform supports and adopts the latest price by default. No marked price is provided yet. The actual price shall be subject to the interface.
