Crypto Futures Fee & Break-Even Calculator

Start with the average entry price and the full position value at that price. A 0.1 BTC position entered at $100,000 has $10,000 of exposure. Whether its margin is $1,000 or $2,000 does not change its commission base. Leverage is therefore not a separate input here: multiplying the same position by leverage again would overstate the costs.

Select Planned entry when the entry price is a reference quote and combined slippage should cover entry plus exit. Select Already opened when you enter your actual average fill; the slippage field then covers only the remaining exit. Changing this selector clears the old allowance so that an entry impact already embedded in your fill is not charged twice.

Set the opening and closing rates independently. You might enter with a maker fill and leave with a market order, or close some quantity through a stop that receives taker treatment. The calculator does not assume that choosing a limit order guarantees a maker fill. Use the rate recorded for an executed opening and the plausible rate for the planned closing.

The main result is an exit price, not a recommended take-profit. It answers a narrower question: where does this fixed quantity cover the entered expenses? Profit beyond that threshold still depends on the fill you receive. The price tick field rounds a long exit upward or a short exit downward so rounding does not leave a small modeled loss.

Take a hypothetical BTC long with a $100,000 entry, $10,000 position value, 0.055% commission on each side, a combined 6 bps execution allowance and $3 of net funding paid. These are example inputs, not a quote for every exchange account. Quantity is 0.1 BTC.

Opening commission is $5.50. The slippage allowance is $6 and carry adds $3. Before closing commission, the trade must recover $14.50. Estimating the closing fee at entry adds another $5.50, giving a convenient $20 starting estimate. But the closing position value is slightly higher when the long exits profitably, so its percentage commission rises too.

Solving both together produces an exit of about $100,200.11. The closing commission becomes approximately $5.511, and gross price profit covers the full $20.011 cost. A $0.10 price tick moves the first covering limit price to $100,200.20. The small difference matters when reconciling arithmetic; it is not a promise that execution will be precise to the last cent.

The waterfall separates opening commission, closing commission, execution allowance, net carry and other costs. Look at the largest contribution before optimizing the smallest. Saving $1 on a maker entry is not an improvement if waiting for that fill leads to an extra $8 of adverse execution or missed quantity.

A commission discount affects only the trading-fee bars. It does not shrink funding automatically. Conversely, a shorter hold can reduce carry without changing either commission rate. Try those alternatives independently and save separate scenarios; otherwise several simultaneous changes can conceal which assumption produced the improvement.

The closing-fee bar uses the solved exit value, while the unchanged-price cost in the numerical results values both legs at entry. Their totals can differ slightly for the reason demonstrated above. If a proposed scenario has no feasible positive exit, the tool withholds the waterfall rather than drawing a misleading commission amount.

A negative opening or closing rate represents a commission rebate. Negative carry represents funding received. Enter each with its sign; do not subtract it from the fee rate or convert a dollar receipt into a percentage without changing the units.

For example, keep the $10,000 position, the two 0.055% commissions and 6 bps execution allowance, but replace the $3 funding payment with a $25 receipt. At an unchanged price, total modeled cost is now −$8. A long can finish slightly below its entry and still be flat after that receipt; the exact solved exit is about $99,919.96. The tool now displays this price instead of hiding it behind a generic “costs covered” message.

That result is useful for reconciling an already received payment. It is much weaker as a prediction of future income. A funding rate can change, and an assumed maker rebate may not apply to a taker exit. Keep earned credits distinct from hoped-for credits when deciding which scenario to rely on.

Quantity equals entry position value divided by entry price. For a long, gross trading profit is quantity multiplied by the difference between exit and entry. For a short, reverse that price difference. Closing commission is quantity multiplied by exit price and the closing fee rate.

Let E be entry price, N be entry position value, c be opening commission plus the slippage allowance plus net carry plus other costs, and f be the closing fee expressed as a decimal. The long exit is E × (1 + c/N) ÷ (1 − f). The short exit is E × (1 − c/N) ÷ (1 + f). Enter 0.055 in the percentage field; the calculation converts it to 0.00055 internally.

The short formula can become infeasible if costs consume more than the position could gain as price approaches zero. A zero or negative theoretical price is not an executable target. Decimal arithmetic avoids ordinary binary rounding drift, but it cannot correct an unsuitable contract model or an assumed future rate.

This is a linear, fixed-quantity model with costs expressed in a common dollar unit. USDT and USDC are treated at their entered dollar value. It does not model an inverse contract’s coin-denominated profit, collateral depegging, multiple partial exits or a changing quantity after scale-ins.

The optional fee loader supplies a stored regular taker baseline and its review date. It does not connect to an account. Some schedules concern a particular channel or product: an API baseline, institutional tier or promotion is not automatically the retail rate. Manual entry is the appropriate route when those details differ.

The funding calculator can transfer a signed cash amount, position value and direction into this page. Its dated transfer still needs a matching entry price and commissions. A slippage estimate from an order book should be entered as a budget, with the snapshot’s age in mind; visible depth is not a guaranteed fill. These handoffs make assumptions inspectable without turning an estimate into an execution instruction.
