Crypto Options Calculator — Bitcoin Options P&L Tool

Start by selecting the Option Type (Call or Put) and your Position (Long if you bought the option, Short if you wrote/sold it). Then enter the key parameters:

• Strike Price — the price at which you have the right to buy (call) or sell (put) the underlying asset
• Current Underlying Price — the live spot price of BTC or the relevant crypto asset
• Premium per Unit — the price you paid (long) or received (short) for the option, denominated in the quote currency (USD)
• Contract Size — how many units of the underlying asset one contract represents (e.g., 0.1 BTC on Deribit)
• Number of Contracts — how many contracts you hold

The calculator shows your current P&L based on intrinsic value, your moneyness status (ITM/ATM/OTM), the break-even price at expiry, and the maximum possible profit and loss for your position structure. Note that this calculator uses intrinsic value only and does not model time value (theta decay) or implied volatility.

The core of any options P&L calculation is the intrinsic value — what the option is worth if exercised today:

• Call Intrinsic Value = max(0, Current Price − Strike Price)
• Put Intrinsic Value = max(0, Strike Price − Current Price)

Long Call

• P&L = (Intrinsic Value − Premium) × Contract Size × Contracts
• Break-even = Strike Price + Premium
• Max Loss = Total Premium Paid | Max Profit = Unlimited

Long Put

• P&L = (Intrinsic Value − Premium) × Contract Size × Contracts
• Break-even = Strike Price − Premium
• Max Loss = Total Premium Paid | Max Profit = (Strike − Premium) × Contract Size × Contracts

Short Call

• P&L = (Premium − max(0, Current Price − Strike)) × Contract Size × Contracts
• Break-even = Strike Price + Premium
• Max Profit = Total Premium Received | Max Loss = Unlimited

Short Put

• P&L = (Premium − max(0, Strike − Current Price)) × Contract Size × Contracts
• Break-even = Strike Price − Premium
• Max Profit = Total Premium Received | Max Loss = (Strike − Premium) × Contract Size × Contracts

Moneyness is determined by the relationship between the current price and the strike: a call is In-the-Money (ITM) when the current price exceeds the strike; a put is ITM when the current price is below the strike. Within ±0.5% of the strike price, the option is considered At-the-Money (ATM).

Example 1 — Long Call (Bullish BTC Trade)

• Option: Long BTC Call | Strike: $70,000
• Current BTC price: $75,000 | Premium: $2,000
• Contract size: 0.1 BTC | 1 contract
• Intrinsic value: $75,000 − $70,000 = $5,000
• P&L: ($5,000 − $2,000) × 0.1 = +$300
• Break-even: $70,000 + $2,000 = $72,000
• Max loss: $2,000 × 0.1 = $200 (if BTC ≤ $70,000 at expiry)

The trader risked $200 (the premium) to gain $300 when BTC rose $5,000 above the strike. This is the core appeal of options: defined risk with asymmetric upside. If BTC had stayed below $70,000, the entire $200 premium would be lost — but nothing more.

Example 2 — Long Put (Bearish / Hedge Trade)

• Option: Long BTC Put | Strike: $70,000
• Current BTC price: $55,000 | Premium: $2,000
• Contract size: 0.1 BTC | 1 contract
• Intrinsic value: $70,000 − $55,000 = $15,000
• P&L: ($15,000 − $2,000) × 0.1 = +$1,300
• Break-even: $70,000 − $2,000 = $68,000

Long puts are popular as portfolio hedges. A BTC holder who buys a put at $70,000 is protected if BTC falls below $68,000 (the break-even). The put effectively acts as insurance — the premium ($200 total) is the cost of protection against a BTC crash.

Example 3 — Short Put (Income Strategy)

• Option: Short BTC Put | Strike: $60,000
• Current BTC price: $65,000 | Premium: $1,500
• Contract size: 0.1 BTC | 2 contracts
• Max profit: $1,500 × 0.1 × 2 = $300 (premium collected)
• Max loss: ($60,000 − $1,500) × 0.1 × 2 = $11,700
• Break-even: $60,000 − $1,500 = $58,500

Short puts are used to generate income or acquire BTC at a discount. If BTC stays above $60,000, the seller keeps the full $300 premium. If BTC crashes to $40,000, the maximum loss is $11,700 — similar to buying BTC outright but at a lower effective cost due to the premium received.
