Leverage Calculator — Position Size & Liquidation
Size a leveraged position safely. Enter your entry, leverage, and account size — see required margin, max position, and liquidation price before you click buy.
How to calculate leveraged position size and liquidation price
- Enter account size. Plug in your trading account balance (USD or stablecoin).
- Set leverage. Pick 2× / 5× / 10× / up to 100× depending on the exchange. Higher leverage means tighter liquidation.
- Enter entry price and direction. Set the entry price and choose Long or Short. The tool computes max position size at your leverage.
- Read the risk. See required margin, liquidation price (how far the market can move before forced close), and PnL at +/-5% / 10% moves.
Frequently Asked Questions
- Is my data stored?
- No. Calculations run entirely in your browser.
- How is liquidation price calculated?
- Liquidation = entry × (1 ± 1/leverage) minus maintenance margin. Real exchange formulas differ slightly — always check exchange docs for production trading.
- Does it account for funding rates?
- No. This tool computes entry-to-liquidation math. Funding rate impact requires separate per-exchange modeling.
- Should I use high leverage?
- High leverage = tight liquidation = high blowup risk. Most pros size positions at 2–5× even when offered 100×.
- Does it work for crypto and forex?
- Yes. The math is identical; only contract specs (lot sizes, tick values) differ — use the unit-converter tab.
- What is maintenance margin?
- The minimum equity that must stay in your position before liquidation triggers. Typically 0.5–1% on crypto perpetual contracts.
