Before Buying Binance Crypto Options, Calculate How Much the Price Must Move to Break Even

Binance

26 October 2026

When you buy a Binance crypto option, the break-even price is not the strike price itself. It is the strike price plus the premium you actually paid, plus a little more to cover fees. Binance's official PnL calculator formula is straightforward: for a call option, possible profit = predicted price − strike price − premium; for a put option, possible profit = strike price − predicted price − premium. Set profit to zero, and the price you solve for is the break-even price. But the calculator page also includes a key note: for simplicity, fees are not included. So the break-even price the calculator gives you is a bit optimistic. In reality, the price needs to move slightly further for you to actually break even.

The premium is the obvious cost; fees are the hidden one

Binance crypto options (European style, settled in USDT) have two types of fees. Trading fees are charged after opening or closing a position. The rate is 0.024% of the underlying spot index price, capped at 10% of the option value per contract. Exercise fees are only charged if you hold to expiration and exercise the option. The rate is 0.015% of the settlement price, also capped at 10%.

Neither of these fees is included in the PnL calculator formula. If you buy an option and hold it until expiration and exercise it, both the trading fee and the exercise fee will eat into your profit. If you close the position before expiration, no exercise fee is charged, but the closing trade itself incurs another trading fee.

For example, if the BTC index price is 60,000 USDT and the contract unit is 1, the trading fee for one contract is 60,000 × 0.024% = 14.4 USDT. If the settlement price is also around 60,000 at exercise, the exercise fee is about 9 USDT. Together, that's more than 20 USDT in costs. This means the break-even price needs to be slightly above "strike price + premium." Exactly how much higher depends on the index price when you trade and the settlement price. Calculate it yourself using the formula above for the most accurate result.

Use the calculator for screening, but don't treat it as net profit

Binance App and website both have a PnL calculator in the options trading interface. On the App, go to Futures → Options → select a contract → calculator icon in the top right corner. On the website, find it in the tools icon at the top right of the options trading page. If you can't find the calculator icon, check whether you are in Easy Trade mode. You need to switch to Classic Trade mode to use it.

Enter your predicted price at expiration, and the calculator will show the "possible profit" and "maximum loss" for each strike price. This feature is useful for quick screening: if your target price shows a positive profit for certain strike prices, your range narrows. But seeing a positive profit does not mean the trade will make money, because fees have not been deducted yet.

A more reliable approach: take the lowest profit figure you see in the calculator, then manually subtract the trading fee (roughly index price × 0.024% × number of contracts). If you plan to hold to expiration and exercise, also subtract the exercise fee. If the result is still positive, then the trade is worth considering. Also, the calculator assumes you trade at the ask price. If your actual fill price is worse, the premium is higher, and the break-even line moves up accordingly.

Number of contracts affects total PnL, not the break-even price

The contract unit for BTC options is 1, with a minimum order of 0.01 contracts. Whether you buy 0.1 contracts or 1 contract, the premium and fees scale proportionally. But the break-even price calculation logic stays the same: strike price + premium and fees per unit of the underlying. The number of contracts only determines how much you gain or lose in total. It does not change how far the price must move for you to break even.

Confirm three numbers before placing an order

First, the strike price. It is directly shown in the contract name, such as the 50000 in BTC-260327-50000-C. Second, the actual premium you paid. Use the order record after execution, not the ask price shown on the order book. Third, the trading fee. Find the fee entry in your transaction history after the trade and confirm the amount. Add the premium and trading fee together, divide by the amount of underlying corresponding to your contract quantity, and you get the actual cost per unit of the underlying. Add that to the strike price for calls, or subtract it from the strike price for puts.

If your view is "BTC will reach 52,000 at expiration" and your calculated break-even price is 51,200, the trade has some room, but not much. If the break-even price is already close to or above 52,000, buying that option means you are betting on a more extreme move than your base case. The premium is a prepaid, non-refundable cost. Calculate the break-even price clearly before placing an order. It is much better than checking your PnL after the trade and feeling uneasy.
