Crypto Position Size Calculator
Size every crypto trade to a fixed slice of your account instead of a guess. Set your risk, entry, and stop-loss to see exactly how many coins to buy and the margin it ties up.
The total capital you are trading with. Position size scales with this number.
The share of your account you are willing to lose if the stop-loss is hit. Most disciplined traders cap this at 1–2%.
The price at which you plan to open the position.
The price where you exit to cap the loss. The gap to your entry sets the per-coin risk.
Used only to estimate the margin this position requires. Leverage does not change your risk in dollars — your stop-loss does.
Risking $10.00 (1% of $1,000) with a $1,000 stop distance sizes you at 0.01 coins.

How position size is calculated
Pick the dollar amount you are willing to lose, then divide it by the distance between your entry and stop-loss. That gives the exact number of coins where a stopped-out trade loses exactly your chosen risk — no more, no less.
Notional value is quantity × entry price, and required margin is notional ÷ leverage. Leverage only changes the margin you must post — it never changes the dollars at risk, because your stop-loss alone defines the loss.
Risk amount on a $1,000 account
| Risk per trade | Risk amount | Trades to halve account* |
|---|---|---|
| 0.5% | $5.00 | ~139 straight losses |
| 1% | $10.00 | ~69 straight losses |
| 2% | $20.00 | ~34 straight losses |
| 5% | $50.00 | ~14 straight losses |
| 10% | $100.00 | ~7 straight losses |
Frequently Asked Questions
Decide the dollars you will risk (account balance × risk %), then divide that by the price distance between your entry and stop-loss. The result is the number of coins where being stopped out loses exactly your chosen risk.
No. Your stop-loss defines the dollars at risk, not the leverage. Leverage only reduces the margin you must post to hold the position. Higher leverage frees up margin but also brings the liquidation price closer to your entry.
Many disciplined traders cap risk at 1–2% of the account per trade so a losing streak does not wipe them out. The reference table shows how the same dollar risk translates into how many consecutive losses your account could absorb.
Notional is the full value of the position (quantity × entry price). Margin is the smaller deposit you actually post to control it, equal to notional ÷ leverage. Position sizing carries substantial risk of loss; size conservatively.
