Know what a contract can pay.

Enter a price, a contract count, and your total costs. See the math behind a standard $1 binary settlement.

YOUR SCENARIO

Total purchase cost$60.00

Payout if your side wins$100.00

Profit if your side wins$40.00

Loss if your side loses$60.00

Break-even probability60.00%

Assumes each winning contract settles at $1 and each losing contract at $0. This is a scenario calculation, not a forecast or a live quote. A break-even probability above 100% means these inputs cannot produce a positive winning payoff.

What the numbers mean

Total purchase cost is the price per contract multiplied by the number of contracts, plus the fees you enter. Winning payout is $1 per contract. Winning profit is that payout minus the total purchase cost. A losing contract pays $0, so the modeled loss is the total cost.

The break-even probability is total cost divided by winning payout. It is the success rate needed for this simplified binary payoff to break even across repeated comparable trades; it is not the market's true probability.

What this calculator doesn't assume

It does not fetch prices, forecast an outcome, model early exits or partial fills, or infer a platform's current fee schedule. Settlement exceptions, refunds, and any costs not entered can change the result. Read the contract and your order preview.
