With fees — and the break-even price they create
Everything below works without live data — the price only fills in a starting entry and exit.
Changes margin and ROI, not the profit in dollars.
Leverage does not change the profit in dollars. Once the position size is fixed, a given price move produces the same gain or loss whatever the leverage; what changes is the margin locked up to hold it, and therefore the percentage return on that margin. A 10% move on a $1,000 position is $100 at 1× and $100 at 20× — the ROI reads 10% or 200% depending on which denominator you use.
What leverage genuinely changes is how far the price can move against you before the position is closed for you. That is a liquidation question rather than a profit question, and it is not modelled here.
Put in an entry, an exit and a position size and this page returns the profit or loss, the return on the margin actually used, and the fees paid. The part most profit calculators omit is the fee itself, which is charged twice — once when the position opens and once when it closes. Leaving it out produces a figure that is always slightly too flattering and, near the entry price, flatly wrong about whether the trade made money.
Because both sides are charged, coming back to your entry price is a loss, not a wash. Break-even is entry × (1 + fee) / (1 − fee) for a long — at 0.1% per side that is about 0.2002% above entry, slightly more than double the one-way fee, because the exit fee applies to the larger exit amount rather than to your entry. That gap is trivial on a single position held for months and decisive for anyone trading several times a day.
Leverage is shown separately for the same reason. It does not change the profit in dollars: once the position size is set, a given price move pays the same amount regardless of leverage. What changes is the margin posted, and therefore the percentage return quoted on it. Treating a higher ROI from leverage as a bigger gain is the same category error as ignoring fees.
⚠️ Not investment advice. Funding payments on perpetual positions, slippage and any withdrawal costs are excluded, and a leveraged position can be liquidated before it reaches your exit price. All decisions and risks are your own.
Because the fee is charged twice — once opening the position and once closing it. Returning to your entry price therefore leaves you down by both fees. For a long, break-even is entry x (1 + fee) / (1 - fee), which at 0.1% per side is about 0.2002% above entry.
The exit fee is charged on the exit amount, which is larger than the entry amount once the price has risen to break-even. Doubling the one-way fee assumes both are charged on the same base, and they are not. The gap is small per trade and compounds quickly for anyone trading frequently.
Not in dollars. Once the position size is fixed, a given price move produces the same gain or loss at any leverage. What leverage changes is the margin locked up, and therefore the percentage return quoted on that margin. A $100 gain is $100 whether the ROI reads 10% or 200%.
It depends on the venue and order type. Binance spot is commonly 0.1% per side, while USD-M futures are nearer 0.02% for maker orders and 0.04% for taker orders. Volume tiers and fee discounts lower these, so the presets are starting points rather than your actual rate.
No. Perpetual futures charge funding at fixed intervals while the position is open, and that is a separate cost from trading fees. For a position held more than a few hours it can outweigh them, and this page does not model it.
Yes. For a short the profit comes from the price falling, and break-even sits below your entry at entry x (1 - fee) / (1 + fee) rather than above it. The direction toggle handles both cases.
