Crypto break-even price: include fees and holding costs

A worked linear-contract example shows why average entry, remaining-position break-even and whole-campaign recovery prices can disagree.

An ivory balance beam with small cost weights and a lime spacer illustrates the adjustment needed to reach break-even.

A crypto break-even price is the exit price that makes gross price P&L exactly cover entry fees, estimated exit fees and other included costs. Calculate it in the trade's settlement currency from actual fills; a displayed entry price alone does not establish that threshold. Spot inventory, fee currency and partial exits can change the equation.

Start by naming what must break even: one remaining position, the complete sequence of entries and exits, or the account after all activity. Those are different accounting boundaries. The realized-versus-unrealized PnL ledger helps separate already booked cash flows from the valuation still open. The worksheet below solves a full close of a linear crypto contract, then extends it to a partial-exit campaign. All prices, fees and funding amounts are hypothetical.

Separate the entry price from the recovery price

An average entry price describes executions. A net break-even price also accounts for costs. For example, Bybit's USDT-contract P&L documentation distinguishes unrealized price P&L from closed P&L that includes trading and funding fees. That is the documented scope of those contracts, not a universal definition for every exchange display.

A calculator can also omit exactly the costs you are trying to recover. Bybit's calculator instructions explicitly exclude trading and funding fees from its calculations. Read the input definitions before treating a target-price output as a net result.

Use the weighted average of actual entry fills, with quantity expressed in the underlying units appropriate to the linear contract. Keep entry commission separate. Record funding as a signed amount: paid funding increases cost; received funding reduces it. The funding settlement ledger explains how to reconstruct that component without assuming a constant rate.

Solve for the exit fee instead of adding percentages

For a full close with no earlier partial exits, define:

InputMeaningUnit
qPosition quantity, positive for either directionUnderlying units
EAverage entry fill priceSettlement currency per unit
AActual entry commissionSettlement currency
HNet holding costs included in this calculationSettlement currency
fExpected proportional exit commission rateDecimal
PAverage exit fill price being solved forSettlement currency per unit

Assume linear price P&L, unchanged quantity, commission charged in the settlement currency and exit commission of q × P × f. A fee rate of 0.05% is 0.0005, not 0.05.

For a long:

Net P&L = q × (P − E) − A − H − q × P × f

Setting the result to zero gives:

Long break-even = (q × E + A + H) / [q × (1 − f)]

For a short, gross price P&L changes sign:

Short break-even = (q × E − A − H) / [q × (1 + f)]

The exit fee depends on the exit notional. Simply adding entry and exit percentages to the entry price is an approximation. These equations solve that dependence exactly under the stated model. Fixed charges can enter H; tiered fees or multiple exit fee rates require the corresponding piecewise calculation.

A long and short with identical starting inputs

Assume a position of 0.2 units at 30,000 USDT, with entry commission of 3 USDT, net funding paid of 4 USDT, and an estimated exit fee of 0.05%. Ignore borrowing, conversion charges and other account activity.

CalculationLongShort
Entry notional6,000 USDT6,000 USDT
Entry commission plus net funding7 USDT7 USDT
Break-even expression6,007 / 0.19995,993 / 0.2001
Break-even exit price, approximately30,050.025029,950.0250

At the long's unrounded threshold, gross price profit is about 10.0050 USDT. The exit commission is about 3.0050 USDT. Subtracting that commission, the 3-USDT entry fee and 4-USDT funding leaves zero apart from decimal rounding.

The long needs an upward move; the short needs a downward move. Their price distances are slightly asymmetric because the closing notional changes in opposite directions. No leverage input is needed for this price-P&L equation at fixed quantity. Leverage and margin still matter to whether the position can survive until any proposed exit.

If another 2 USDT of funding is paid before the long closes, its threshold rises to about 30,060.0300. That is a revised cost record, not evidence that the market will return there. A break-even price is an accounting threshold, not an exit recommendation.

Partial exits change the question

Continue the hypothetical long. Suppose half the position, 0.1 units, closes at 31,000. Its gross realized price profit is 100 USDT. The partial exit fee is 0.1 × 31,000 × 0.0005 = 1.55 USDT.

Charge all original entry commission and the 4-USDT funding cost to the campaign ledger now. The net amount carried forward is:

100 − 1.55 − 3 − 4 = 91.45 USDT

For the remaining 0.1 units, assuming no further holding costs, the complete campaign result at final price P becomes:

91.45 + 0.1 × (P − 30,000) − 0.1 × P × 0.0005

Its zero is about 29,100.0500. The earlier realized profit permits the campaign to finish near zero even if the remainder closes below entry. It does not make the remaining position risk-free. A further decline can consume that realized profit and more.

An exchange may allocate entry and funding costs proportionally across partial closes, producing a different displayed figure for the remaining leg. Define the boundary before comparing displays. Use the partial-fill management guide to reconcile what actually closed; a submitted exit is insufficient evidence.

Spot fees can reduce the quantity you can sell

Do not copy the linear-contract equation into a spot purchase without checking inventory. If a purchase fee removes some received base asset, the sellable quantity is smaller than the gross filled quantity. If commission is paid in another token, that token also carries an economic cost.

Binance's spot commission reference documents commission calculations using the received asset and a separate discount asset under applicable settings and balances. Its numerical examples are fictional. They are evidence of calculation mechanics, not a fee quote for your account.

For an unleveraged spot holding, a useful cash-ledger expression is:

Break-even sale price = total included acquisition cost / [actual sellable quantity × (1 − exit fee rate)]

This assumes the sale fee comes from quote proceeds, all included costs have been valued in that quote currency, and the whole sellable quantity exits. Avoid charging an entry fee twice by both reducing inventory and adding the same fee to cash outlay. The DCA take-profit cost example works through spot cash flows and target bases in more detail.

Turn the threshold into a usable check

Before using a calculated price, record the instrument, direction, quantity, settlement asset, entry fills, fee assets, accumulated costs and expected exit rate. Mark every future cost as an estimate. Recalculate after additions, partial closes, fee changes or funding settlements.

Then check executable prices and permitted price increments. A long's theoretical recovery sale may require rounding upward; a short's recovery buy may require rounding downward. Fees can also round at the fill level. Recompute the net result after rounding rather than relying on the displayed decimal.

Use actual average fills when reviewing a closed trade. Those fills already contain execution price effects; subtracting a second generic slippage allowance would double-count those effects. Before execution, however, a chart price may differ from available bids or asks. The spread guide explains that distinction. A resting limit can remain unfilled, while a market close can cross several prices.

This worksheet excludes inverse-contract payoffs, liquidation charges, taxes and changes in the settlement asset's purchasing power. It also cannot promise a fill at break-even. Keep the calculation beside the risk plan so that waiting to recover costs does not silently replace the original reason for exiting. When several positions remain open, the portfolio correlation worksheet tests their combined shock loss; separate break-even prices do not establish a tolerable account-level loss.
