Create AccountCrypto Position Size Calculator
Size a crypto trade from your entry and stop prices, in coins and in dollars.
Your Result
The calculation runs in your browser. Rates used for currency conversion are indicative — check your broker for the exact figure.
Crypto has no standard lot, so position size is quoted in coins or in dollars. That makes the arithmetic simpler than forex — but the volatility makes the sizing matter more, because a stop that has to sit five percent away is normal rather than exceptional.
The calculator also reports the leverage needed. If the position value exceeds your balance, you are borrowing, and on an asset that can move fifteen percent in a day that is where liquidation risk comes from rather than from the stop being hit.
When to use it
- On every crypto entry, since a wide stop and a fixed risk mean the size changes constantly.
- When the stop has to sit outside a volatile range and the position must shrink to match.
- Before using leverage, to see whether the trade actually requires it.
- When moving between coins with very different prices.
The distance between entry and stop is the loss per coin, so the risk divided by that distance is the size.
Risk Amount = Balance × Risk %
Loss Per Coin = |Entry − Stop|
Position Size = Risk Amount ÷ Loss Per Coin
Leverage Needed = Position Value ÷ Balance- No contract size is involved. One unit is one coin, so the arithmetic is the same for Bitcoin at $64,000 and a token at $0.40.
- Leverage below 1 means the position fits inside the balance and no borrowing is needed.
- Percentage stops matter more than dollar stops in crypto. A $3,000 stop is tight on Bitcoin and impossible on a small-cap token.
A $10,000 account risking 1% on Bitcoin, entering at $64,000 with a stop at $61,000.
Working: $100 ÷ $3,000 = 0.03333 BTC, worth $2,133 at entry. That sits comfortably inside a $10,000 balance, so no leverage is required. Widen the stop to $55,000 and the size falls to 0.0111 BTC — the risk stays at $100 either way.
Why is my position value so much smaller than my balance?
Because crypto stops are wide in percentage terms. A 5% stop with 1% risk means the position can only be a fifth of the account. That is the arithmetic working correctly, not a mistake.
Do I need leverage for crypto?
Usually not, if you are sizing from risk. Leverage becomes necessary only when the stop is very tight or the risk per trade is high — and both of those are decisions worth re-examining.
How does liquidation differ from a stop loss?
A stop closes the trade at a price you chose. Liquidation is the exchange closing it because the margin ran out, usually at a worse price and with a fee. Sizing from risk keeps the stop well in front of the liquidation level.
Does this work for altcoins?
Yes. The calculation does not care about the price of the coin, only the distance between entry and stop. It works the same at $64,000 and at $0.004.
