Futures Calculator
Size contracts from a risk budget, or solve the stop distance a fixed size can afford. Read dollars first: margin is only a door fee.

Questions this tool usually raises
- How is futures P&L calculated?
- From points moved, not ticks. Each contract has a point value, so P&L is the price move in points times the point value times the number of contracts. Ticks (tick size × point value = tick value) are shown for convenience, but the dollar math runs off points so it stays exact.
- What is the “Solve for” toggle?
- It picks which field the calculator works out for you. Solve for contracts takes your stop and solves the largest whole number of contracts whose stop-out loss stays within your risk budget (account size × risk %), rounding down so actual risk lands at or just under your %. Solve for stop takes your contracts and risk and works backward to the stop distance that fits the budget, then sets the target from your risk:reward. The solved field is locked so the math always balances.
- What is a good account-risk percentage per trade?
- Most professional traders risk a small, fixed slice per trade, commonly around 1–2% of the account. The Account risk tile shows where your current size lands; keeping it small is what lets you survive an inevitable losing streak.
- Why does it say “wrong side of entry”?
- For a long, the stop must sit below entry and the target above it; for a short, the reverse. When you type or step a stop or target, the calculator clamps it to the nearest valid level (one tick past entry), so you mostly see this hint only mid-edit. In Solve for stop the stop and target are derived, so they can never land on the wrong side.
- What is the difference between margin and risk?
- Margin is the deposit your broker requires to hold the position, and it can be a tiny fraction of the notional value. Risk is what you actually lose if the stop is hit. Margin tells you what you can trade; risk % tells you what you should. Always size by risk, not by how many contracts margin allows.
- Does the risk:reward preset change my stop?
- No. The 1:1, 1:2 and 1:3 chips keep your stop where it is and set the target that many times the stop distance away from entry. Move your stop first, then pick the reward multiple.
