Crypto Position Size Calculator

Free toolSame maths as CoinGPT's Review & Execute

Work out how big a position to take from the two numbers that matter: how much you're willing to lose, and where your stop is. Leverage comes last. This calculator uses the same rules as CoinGPT's Review & Execute screen.

Amount at risk-
Stop distance-
Position size-
Gain at target-
Leverage-
Margin held-
Est. liquidation-

Liquidation is an estimate for isolated margin with a 0.6% allowance for maintenance margin and fees. Exchanges use tiered rates. Fees and slippage are not included in the loss and gain figures.

Skip the maths on every trade. In the CoinGPT app, the Trade Agent drafts the entry, stop and target, and Review & Execute sizes it from your risk and sends it to your exchange with the stop and target attached.

How the calculator works

  1. Amount at risk = balance × risk %. At $1,000 and 1%, that's $10.
  2. Position size = amount at risk ÷ stop distance. $10 ÷ 0.49% is about $2,050, or 0.027 BTC at 75,890.
  3. Recommended leverage is the lowest of 1x, 2x, 3x, 5x, 10x, 15x, 20x, 25x, 50x and 100x where the margin is at most a quarter of your balance and the estimated liquidation sits at least twice as far from entry as your stop. These are the same rules CoinGPT uses.
  4. If liquidation would sit at or before your stop, the leverage is blocked: the exchange would close you out before your stop ever gets a chance.

The reasoning behind 1 to 2% risk, with a worked example, is in how much to risk per crypto trade. Choosing the stop itself is in where to put your stop loss.

Questions

Divide the amount you are willing to lose by the distance from entry to stop. With a $1,000 account at 1% risk ($10) and a stop 0.49% away, the position is about $2,050.
Not at the stop. With the same position size and stop, the loss at the stop is the same at any leverage. Leverage changes the margin held and moves the liquidation price closer to entry.
If liquidation sits at or before your stop, the exchange closes the trade before the stop can, and you lose the margin. This calculator, like CoinGPT, wants liquidation at least twice as far from entry as the stop.
It is an estimate for isolated margin with a 0.6% allowance for maintenance margin and fees. Exchanges use tiered rates, so check your exchange's own figure before trading.

For education only, not financial advice. Trading involves substantial risk of loss. In a fast market price can move past a stop.
