Crypto Position Size Calculator
Calculate the position size that risks a fixed percentage of your account.
Please note: Cryptocurrency is highly volatile and can lose value rapidly. All prices are entered manually — no live market data is used. Nothing here is investment advice.
What the Crypto Position Size Calculator does
Position size follows from the risk you accept and the distance to your stop. In crypto the wide stops demanded by volatility naturally produce smaller positions — resisting that by tightening the stop simply guarantees being stopped out by noise. This version adds leverage and margin-required, and sizes in fractional coin units rather than whole shares — for an unleveraged stock or forex position, the trading position size calculator is the simpler tool.
Formula
Risk amount = Account × Risk % ÷ 100Quantity = Risk amount ÷ |Entry − Stop|Position value = Quantity × Entry price

Worked example
A $10,000 account risking 1%, entering ETH at $2,400 with a stop at $2,250.
- Account
- 10000
- Risk
- 1
- Entry
- 2400
- Stop
- 2250
$100 ÷ $150 = 0.6667 ETH, a position worth $1,600.
Reading the result
- Position size and account risk are fixed together by design: whatever the stop distance turns out to be, the position size shrinks or grows so the amount at risk stays the entered percentage — a wide stop does not mean a riskier trade, it means a smaller one.
- "Leverage needed" is the leverage required to hold this position size, not a recommendation to use it — a low percentage risked can still show a leverage figure above 1× once the stop is wide enough.
Common mistakes
- Tightening the stop to make the position size bigger. The stop should reflect where the trade idea is actually invalidated, not be reverse-engineered from a desired position size.
- Reading "margin required" as the total cost of the trade. It is the collateral this position needs at the chosen leverage — the amount at risk if the stop is hit is the separate, smaller figure above it.
Frequently asked questions
Should I risk less in crypto than in stocks?
Many traders do, because gaps and exchange outages can push actual losses past the stop. Half a percent to one percent is a common crypto range.
