Gross PnL
The position quantity multiplied by the favorable or unfavorable price move. It excludes fees and funding.
Estimate gross and net profit or loss, or reverse-calculate the exit price needed for a target net PnL or ROE, including fees and funding.
Positive funding is modeled as paid by longs and received by shorts. Enter a negative rate when shorts pay longs.
Fee presets are editable reference rates. Your VIP tier, rebates, token discounts, and contract can change the actual fee.
PnL measures how much a position gains or loses between its entry and exit prices. A useful result separates the market move from trading costs, because gross PnL can look positive while fees and funding make the trade less profitable—or negative.
The position quantity multiplied by the favorable or unfavorable price move. It excludes fees and funding.
Gross PnL after entry fees, exit fees, and funding. You can also enter a target net PnL and solve the required exit price.
Net PnL divided by margin used. Leverage changes the margin and therefore ROE, but it does not change gross PnL for a fixed notional.
Calcoring models USDT-margined linear perpetuals. Position quantity is derived from the input mode you select: margin multiplied by leverage, a direct position notional, or the asset quantity itself.
Long gross PnL = Quantity × (Exit price − Entry price)Short gross PnL = Quantity × (Entry price − Exit price)Net PnL = Gross PnL − Entry fee − Exit fee + Funding PnLTarget exit = (Target net PnL − Net PnL at a $0 exit) ÷ [Quantity × (Direction − Exit fee rate)]Maker and taker rates can differ at entry and exit. Funding is a periodic transfer between long and short traders, not an exchange trading fee. Calcoring keeps each component visible so you can change the assumptions instead of accepting one blended cost.
With $1,000 margin and 5x leverage, the opening notional is $5,000 and the BTC quantity is about 0.076923. The favorable $2,500 move creates about $192.31 in gross PnL. Using a 0.02% maker entry, 0.05% taker exit, and one 0.01% funding payment produces roughly $188.21 in net PnL. In target mode, entering $188.21 returns approximately the same $67,500 exit price.
Yes. Choose Target net PnL or Target ROE. The calculator converts the target ROE into a dollar result from margin, then solves the long or short exit price after entry fee, exit fee, and funding.
Leverage lets the same margin control a larger notional. It increases profit and loss relative to margin, but it does not change PnL when the position notional is already fixed.
A chart usually shows only price movement. Entry fees, exit fees, funding, slippage, and partial fills can reduce the amount that reaches your account.
Terminology varies by platform. On this page, price return uses position notional while ROE uses the margin committed to the position.
Yes. When the funding direction favors your side, the payment is credited. The calculator accepts positive or negative funding rates to model both cases.
It is an estimate based on the fee and funding inputs shown. Changing funding, slippage, rebates, or exchange rounding can move the actual break-even price.
