What this calculator does
This calculator helps estimate how large a crypto position could be when you decide the dollar amount you are willing to risk before opening the trade. It uses account balance, risk percentage, entry price, and stop-loss price to calculate quantity and position value.
The tool automatically interprets the setup as long when the stop-loss price is below entry, and short when the stop-loss price is above entry.
Inputs and results
Account balance is the trading capital used for the risk calculation. Risk per trade is the percentage of that balance you are willing to lose if the stop-loss is reached. Entry price is the planned trade price. Stop-loss price is the price where the trade would be closed if it moves against the setup.
Leverage changes the estimated margin required to open the position. It does not increase the selected dollar risk when position size is based on stop-loss distance. Optional trading fee estimates show how fees may add cost beyond the intended risk amount.
How the calculation works
Risk amount equals account balance multiplied by risk percentage. Stop distance is the absolute difference between entry price and stop-loss price. Crypto quantity equals risk amount divided by stop distance. Position value equals quantity multiplied by entry price.
Tighter stops produce larger calculated position sizes because each unit risks fewer dollars. Wider stops produce smaller position sizes because each unit risks more dollars before the stop is reached. If the calculated margin exceeds the account balance, the calculator shows a validation message instead of presenting an unfundable size.
Worked example
Suppose your account balance is $10,000 and you choose to risk 1% on a long setup. Your entry price is $60,000, your stop-loss is $58,500, and leverage is 5x.
The risk amount is $100. The stop distance is $1,500. Dividing $100 by $1,500 gives 0.06666667 crypto quantity. Multiplying that by $60,000 gives a position value of about $4,000. At 5x leverage, estimated margin required is about $800.
Important limitations
Real exchange results can differ because of fees, spread, slippage, funding costs, liquidation rules, minimum order sizes, rounding, and contract specifications. Stop orders are not guaranteed to execute at the exact stop price, especially during fast market movement.

Frequently asked questions
How do I calculate crypto position size?
Choose the dollar amount you are willing to risk, divide it by the distance between entry price and stop-loss price, then multiply the resulting quantity by entry price to estimate position value.
What percentage of my account should I risk per trade?
That depends on your own plan and risk tolerance. Many traders keep risk per trade small, but this calculator does not recommend a specific percentage.
Does leverage increase my risk?
Leverage reduces the margin required to open a position. If the position is sized from a fixed risk amount and stop-loss distance, leverage does not change the intended loss at the stop, although liquidation rules and execution risk still matter.
Why does a tighter stop increase position size?
A tighter stop has a smaller dollar distance from entry, so the same risk amount can cover a larger quantity before the stop is reached.
Can I use this calculator for short trades?
Yes. If the stop-loss price is above the entry price, the calculator interprets the setup as a short position.
Does this include trading fees?
You can enter an optional fee percentage. The calculator estimates round-trip fees, but actual fees, spread, slippage, funding, and exchange rounding may differ.
Why might my exchange position size differ from the calculator?
Exchanges may apply minimum order sizes, step sizes, contract specifications, fees, price increments, leverage rules, and rounding that change the final order size.
