What is a crypto margin calculator?

A crypto margin calculator helps you estimate how much collateral you need to open a leveraged position, and what your potential PnL and return on equity (ROE) look like based on your entry and exit prices. It supports both long and short scenarios and lets you quickly run what-if analyses before you commit capital.

What are the technicals?

  • Notional value: entry price × quantity (contract size or asset amount).
  • Required margin: notional ÷ leverage (ignores fees; exchange rules may vary slightly).
  • Maintenance margin: minimum equity required to keep the position open; varies by exchange and tier.
  • PnL: (exit price − entry price) × quantity for longs; reversed sign for shorts.
  • ROE: PnL ÷ initial margin × 100%.
  • Liquidation risk: depends on maintenance margin, fees, and funding; calculator provides directional guidance only.

How do you calculate margin requirement in crypto?

Formula: Required margin = (Entry price × Quantity) ÷ Leverage.

Example: Long 0.5 BTC at $60,000 with 10× leverage → Required margin = (60,000 × 0.5) ÷ 10 = $3,000.

Notes: Exchanges may add buffers, tiered maintenance margins, funding fees, and maker/taker fees. Cross vs. isolated margin changes how risk is shared across positions.

Biggest benefits of using this calculator

  • Plan trades faster with instant what‑if scenarios.
  • Avoid underfunding by estimating margin needs before opening positions.
  • Understand risk and ROE clearly for both long and short strategies.
  • Compare different leverage levels to balance risk and capital efficiency.
  • Reduce manual mistakes when crunching numbers under pressure.

FAQ

What inputs do I need for the margin calculator?▼
Entry price, exit price (optional for PnL/ROE), quantity (or size), leverage, and long/short side. Fees are not included in the simplified margin formula.
Does the calculator include fees or funding?▼
No. Results approximate initial margin using notional ÷ leverage. Actual requirements vary by exchange, fee schedule, funding, and maintenance tiers.
Cross vs. isolated margin—what changes?▼
Cross shares risk and equity across positions; isolated confines risk to the position. Our estimate applies to initial margin; liquidation risk depends on maintenance rules.
How accurate is liquidation guidance here?▼
It’s directional only. Liquidation depends on maintenance margin, fees, funding, insurance funds, and real-time price moves specific to each venue.
Can this be used for spot margin?▼
Yes, the same principles apply when borrowing to increase spot exposure, but funding rates and borrowing terms will affect real costs and risks.
