Crypto Position Size Calculator – Size Every Trade by Risk and Stop-Loss
Position Size Calculator
Use this free crypto position size calculator to work out how much to put into each trade based on your risk rules.
Quick answer
To use this crypto position size calculator, enter your account balance, the percentage you are willing to risk on the trade (1% or 2% is common), your entry price and your stop-loss price, then press Calculate Position Size. Position size = (balance × risk %) ÷ stop-loss distance. For example, a $10,000 account risking 1% with entry $50,000 and stop $48,000 (4% away) gives a $2,500 position, or 0.05 BTC.
Most trading losses that wreck accounts come from positions that were simply too big. Professional traders decide how much they can lose on a trade first, then size the position to match the stop-loss. This free crypto position size calculator does that maths for you, for spot or futures trades on any coin.
I added a line under the results that tells you when a tight stop-loss makes the position bigger than your balance, and roughly how much leverage that would require, so you are not surprised when you try to place the order.

How to Use the Crypto Position Size Calculator
Step 1: Enter your balance and risk per trade
Type your total trading account balance and the percentage you will risk on this trade, or click 1%, 2% or 5%. Many traders never risk more than 1% to 2% of their account on one trade.
Step 2: Add entry and stop-loss prices
Enter the price you plan to buy or short at and the price where your stop-loss will close the trade. For a long the stop is below the entry; for a short it is above. Press Calculate Position Size.
Step 3: Read the position size, risk amount and stop distance
The result shows the recommended position size in USD and in tokens, the maximum amount at risk and the stop-loss distance in percent. A note underneath shows what share of your balance the position uses or how much leverage it would need.
The Position Size Formula
- Amount at risk = account balance × risk %.
- Stop-loss distance = |entry − stop| ÷ entry.
- Position size (USD) = amount at risk ÷ stop-loss distance.
- Position size (tokens) = position size in USD ÷ entry price.
Crypto Position Size Calculator Tips
- Place your stop-loss where the trade idea is proven wrong, then let the calculator set the size.
- A tighter stop means a bigger position for the same risk, which can require leverage.
- Include trading fees and possible slippage when choosing your risk percent.
- Keep total risk across all open trades within a limit you are comfortable with.
- Write the planned size down before entering so emotions do not change it.
Why Risk Management Matters
If you risk 1% per trade, ten losing trades in a row cost about 10% of your account, which is recoverable. Risking 10% per trade could wipe out most of the account in the same streak. Consistent position sizing keeps you in the game long enough for a good strategy to work. This calculator supports that discipline but is not financial advice.
Frequently Asked Questions
Is this crypto position size calculator free?
Yes. It is free with no sign-up and no exchange account needed.
How much should I risk per trade?
Many traders risk 1% to 2% of their account per trade. The right level depends on your strategy and tolerance for losses.
Does it work for short trades?
Yes. Enter a stop-loss above the entry price for a short; the calculator uses the distance either way.
Why is my position bigger than my balance?
A very tight stop-loss means a small price move equals your full risk, so the position must be large. The calculator shows the leverage that would require.
Does it include fees?
No. Trading fees and slippage add a little to the real loss if the stop is hit, so allow for them in your risk percent.
Is this financial advice?
No. It is a risk management calculator for education and planning only.
