Futures P&L Calculator

Long/Short + entry/exit + leverage → Net PnL / ROI / ROE

What is the Futures P&L Calculator?

The Futures PnL Calculator computes profit, return on margin and required margin from direction (long/short), entry/exit prices, leverage and collateral.

How do I use the Futures P&L Calculator?

Run the scenario before the trade: plug in both target and stop to confirm the R/R is sound (≥2:1). Note the return shown is on margin — at 10x, a 1% price move is ±10% on collateral.

What should I watch out for?

Funding and trading fees are excluded — at high leverage and frequency they can eat most of the edge, which is precisely what the Fee Comparison and Rebate Calculator quantify.

How the Futures P&L Calculator works

Calculates the gross and net profit or loss of a linear futures trade from side, entry, exit, quantity, leverage and per-side fee, and shows return on notional (ROI) and return on margin (ROE). Use it to test scenarios before you enter.

What you enter

  • Side: Long or Short
  • Entry price (USD)
  • Exit price (USD)
  • Quantity (coins)
  • Leverage (≥ 1)
  • Fee (% per side), default 0.055

What it shows

  • Net PnL after fees (USD)
  • ROI (% of notional) and ROE (% of margin)
  • Gross profit
  • Total fees (open + close)
  • Notional value
  • Initial margin

How to use it

  1. Select Long or Short.
  2. Enter the entry and exit prices (try your target, then your stop).
  3. Enter the quantity in coins.
  4. Set leverage and your account's per-side fee.
  5. Read net PnL, ROI and ROE; compare the target and stop scenarios.

Formula

Notional = entry × quantity; margin = notional / leverage; gross = (exit − entry) × quantity for a long, (entry − exit) × quantity for a short; fees = entry × quantity × fee % + exit × quantity × fee %; net = gross − fees; ROI = net / notional × 100; ROE = net / margin × 100.

Worked example

Long 0.5 BTC, entry 50,000 USD, exit 55,000 USD, 10×, 0.055% fee per side. Notional = 25,000 USD; margin = 2,500 USD. Gross = 5,000 × 0.5 = 2,500 USD. Fees = 13.75 + 15.125 = 28.875 USD. Net = 2,471.13 USD. ROI = 2,471.125 / 25,000 ≈ 9.88%; ROE = 2,471.125 / 2,500 ≈ 98.85%.

How to read the result

  • ROE scales with leverage; ROI does not.
  • Fees are charged on both sides, so they weigh more on small moves.
  • Run both the target exit and the stop exit to see planned reward and risk.

Limits and cautions

  • Funding payments are not included.
  • Slippage and spread are not modeled.
  • Leverage magnifies losses on margin just as much as gains.

Common questions

How do you calculate futures profit?

Multiply the price change by the quantity (flip the sign for shorts) and subtract fees on the entry and exit notional. Divide by margin for the return on margin.

What is the difference between ROI and ROE?

Here ROI is net PnL divided by position notional; ROE is net PnL divided by initial margin. At 10× leverage ROE is about ten times ROI.

Does leverage increase my profit?

Leverage does not change dollar PnL for a given quantity; it reduces the margin posted, so the percentage return on margin, and the loss, is magnified.
