How to calculate crypto futures profit
It estimates profit or loss, fees, margin, and return on the cash you posted for a leveraged perpetual or dated futures trade. You type entry, exit, quantity, side, leverage, and a round-trip fee. The headline is net dollars after fees, not the coin's percent move.
For USDT-margined contracts, gross profit is (exit − entry) × quantity for a long, and the reverse for a short. Net subtracts round-trip fees, usually a percent of the trade on the way in and out. A common perpetual taker round trip is about 0.08%. ROE is net profit divided by initial margin (trade size ÷ leverage). A $100 gain on $500 of 10× margin is 20% ROE — not a 20% move in Bitcoin. Funding is a separate cash flow paid while you hold a perpetual; subtract it if you sit through several 8-hour intervals. This page does not pull a live price, and it does not check whether liquidation hit first.
Example
Futures profit example: 10× long of 0.2 Bitcoin
Match this on the sliders: $50,000 to $55,000, 0.2 coins, 10×, about 0.08% fees.
- Gross
- $1,000
- Fees
- ~$8
- Net
- ~$992
- Margin posted
- $1,000
- ROE
- ~99%
- Coin move
- 10%
That ~99% is a return on $1,000 of margin, not on Bitcoin. Bitcoin moved 10%. Mixing those two percents is how people brag themselves into a 50× account.
| Piece | In words | This example |
|---|---|---|
| Gross | (exit − entry) × coins | $1,000 |
| Fees | Round-trip % × trade size | About $8 at 0.08% |
| Net | Gross − fees | About $992 |
| ROE | Net ÷ margin posted | ~$1,000 posted · ~99% |
Limits
What this futures calculator cannot do
- It will not subtract funding. Use the funding calculator if you hold through prints.
- It will not estimate liquidation. Check that next if leverage is more than about 3×.
- It will not pull a live price.
- It will not file tax on a close.
If you do not yet know the quantity, start on the position-size calculator so the size comes from a stop, not from leftover margin.

Gross is (exit − entry) × quantity for a long, or the reverse for a short. Net subtracts round-trip fees. A common perpetual taker round trip is about 0.08%. ROE is net divided by the margin you posted.
Return on the margin you posted. A $100 gain on $500 of 10× margin is 20% ROE — not a 20% move in Bitcoin. Do not mix that percent with a spot profit percent.
No. Funding is a separate cash flow paid while you hold a perpetual. Use the funding-rate tool and subtract it if you sit through several 8-hour prints.
No. A green PnL does not mean the trade survived. Check the liquidation calculator if leverage is more than about 3×.
Yes. Leaving them out makes a small scalp look free. Open plus close is the round trip. Maker fees are lower; taker is the conservative default.
Closing a futures trade can be a taxable event. This page is pre-tax. Talk to someone who files returns if the number is large.
No. You type the entry and the exit (or the mark you would close at). Your fills are the source of truth.
