Position Side
Position sizing for Bybit traders
With 100× available on Bybit, it is tempting to use high leverage and take large positions. But position size should be determined by risk tolerance, not leverage. The risk-based sizing formula:
- Max loss = accountBalance × riskPercent%
- Stop distance = |entry − stop| / entry
- Position size = maxLoss / stopDistance
This formula ensures that if your stop loss triggers, you lose exactly your planned risk percentage — regardless of what leverage you use. On Bybit, set your stop loss order immediately after opening a position to enforce the limit automatically.
Bybit fee structure
Bybit charges maker fee 0.01% and taker fee 0.06% on perpetual futures. Maximum available leverage is 100×. This calculator pre-fills these defaults so you get accurate results without needing to look up the fee schedule. If you are on a VIP tier with discounted fees, adjust the fee fields accordingly.
Maker orders (limit orders that add liquidity) cost less than taker orders (market orders that remove liquidity). On Bybit, using limit orders for both entry and exit can reduce your total fee cost significantly compared to market orders.
Frequently Asked Questions
How do I calculate position size from risk?
Position size = max loss / loss per unit. Loss per unit = |entry − stop| + fees. This ensures your worst-case loss never exceeds your limit.
What is the 1–2% rule?
Risk no more than 1–2% of your account per trade. If your account is $10,000 and you risk 1%, your max loss per trade is $100.
What are Bybit perpetual futures fees?
