Does this calculate a liquidation price?

No. Liquidation rules vary by exchange, contract and margin mode. The stop loss should be evaluated separately from liquidation risk.

Crypto Position Size Calculator

Q: How is crypto position size calculated?

The risk budget is divided by the loss per unit between the entry and stop prices, including the entered round-trip cost estimate.

Q: Does leverage increase the recommended position size?

No. This calculator sizes the position from the cash amount you are willing to lose. Leverage only changes the estimated margin required.

Choose how much of your account you can risk, then calculate a position size from your entry and stop—not from emotion or maximum leverage.

Leverage warning: leverage reduces estimated margin, not the planned loss at your stop. It can introduce liquidation and funding risk that this calculator does not model.

How to use the position size calculator

STEP 1

Set your risk budget

Enter your account balance and the maximum percentage you are prepared to lose if the stop executes.

STEP 2

Define the invalidation

Enter the planned entry and stop-loss prices. A wider stop produces a smaller position.

STEP 3

Review total exposure

Check quantity, notional value and margin before considering liquidity, liquidation and exchange rules.

Core formula

Position quantity = cash risk budget ÷ (stop distance per unit + estimated round-trip cost per unit).

This helps keep the chosen account risk consistent when prices and stop distances change.

Important limitations

• A stop order may fill worse than its trigger price.
• Funding, borrowing and taxes are not included.
• Liquidation rules differ by venue and margin mode.
• Results are educational, not financial advice.

Frequently asked questions

How is crypto position size calculated?

The calculator divides your chosen cash-risk budget by the expected loss per unit between entry and stop, including your cost estimate.

Does leverage increase the recommended position size?

No. The recommendation is based on risk. Leverage only changes the estimated margin required to open that notional position.

Does this calculate liquidation price?

No. Liquidation depends on the exchange, contract, maintenance margin and margin mode. Confirm those details directly with the venue.
