Detailed Summary

When you buy an option on Bybit, paying the premium is only part of the cost, and a positive number next to your open position does not mean you have locked in a profit. This guide breaks down what a buyer actually pays and how P&L looks across three position states: still open, closed early and held to expiration.

Key Takeaways:

  • The premium and the trading fee are separate costs, and both reduce your net result.

  • Open P&L is an unrealized estimate based on the mark price, not a guaranteed exit amount.

  • Closing early and holding to expiration produce different final P&L calculations and fee treatment.

What does an options buyer pay on Bybit?

A buyer's upfront cost has two parts: the premium and the opening trading fee.

  • Premium = price per unit × quantity. This is the price you pay the seller for the contract. It is also your maximum possible loss on the option itself, before fees.

  • Opening trading fee is charged separately when the order executes. The fee depends on whether the order is a maker or taker order, the current index price and the option price.

Bybit Options are settled in Tether (USDT), so the premium and P&L in this guide are expressed in USDT. This guide covers the buyer's side only.

Open, closed early or expired: How P&L changes

Your position can end in one of three ways. Each calculates P&L differently.

  • Still open: Unrealized P&L uses the mark price versus your average entry price. It changes continuously, excludes fees and is not a guaranteed exit amount. The mark price may differ from the price you could actually execute at.

  • Closed early: You sell the option before expiration. The executed exit price determines the result, and both the opening and closing trading fees are deducted.

  • Held to expiration: The contract settles automatically. If the option finishes in the money, the buyer receives the intrinsic value (settlement price minus strike for a call, or strike minus settlement price for a put). The premium, opening fee and any applicable delivery fee are subtracted. If the option finishes out of the money, intrinsic value is zero and the buyer loses the premium plus fees.

One buyer example across three states

Consider this hypothetical Bitcoin (BTC) call:

  • Strike: $52,000

  • Premium: $1,000 per BTC

  • Quantity: 0.1 BTC

  • Total premium paid: $100

  • Index price at entry: $50,000

  • Opening fee (non-VIP taker): $1.50

Below are three alternative outcomes for the same position, not a sequence.

Still open — mark price reaches $1,200 per BTC

Unrealized P&L = ($1,200 − $1,000) × 0.1 = $20. This excludes fees and may change with the next price tick.

Closed early — exit price $1,200 per BTC, index $52,000

Gain on the trade = ($1,200 − $1,000) × 0.1 = $20. Closing fee (non-VIP taker) = $1.56. Net P&L = $20 − $1.50 − $1.56 = $16.94.

Held to expiration (non-daily contract) — settlement price $55,000

Intrinsic value = ($55,000 − $52,000) × 0.1 = $300. Delivery fee = $0.825. Net P&L = $300 − $100 premium − $1.50 opening fee − $0.825 delivery fee = about $197.68. Daily options do not incur a delivery fee.

What should you check before acting?

  • Mark price ≠ exit price. The unrealized P&L you see uses the mark price. The price you actually receive when closing may differ, especially if the bid-ask spread is wide.

  • Fees vary. Trading fee rates depend on maker or taker order type and VIP tier. Delivery fee rates vary by underlying asset. Check the current fee schedule rather than relying on one set of numbers.

  • Risk reminder. A buyer can lose the entire premium plus fees if the option expires out of the money.

Understanding costs and P&L before you trade

A buyer's cost is the premium plus the opening fee. From there, P&L depends on whether you hold, close early or let the contract expire, each with its own fee treatment. Checking the mark price, the bid-ask spread and the applicable fees before acting helps you set realistic expectations.
