Your trade

Enter entry and exit prices. Quantity is optional — you can calculate the result per unit first.

Trade direction

Entry price

Exit price

Asset quantity (optional)

Leave empty for P&L per 1 unit. Results use the same quote currency as your prices (e.g. USD).

Fees, slippage & leverageOptional

All costs start at zero. Change them to match your actual maker/taker fees and expected adverse execution.

Entry fee (%)

Exit fee (%)

Entry slippage (%)

Exit slippage (%)

Leverage (illustrative)

Margin estimate = modeled entry notional ÷ selected leverage. Exchange rules and liquidation are excluded.

A linear, single-entry, single-exit calculation. The value of short trades is modeled mathematically, not as ordinary spot ownership. COIN-M inverse contracts require a different formula. No live market price, funding, interest, taxes or liquidation modeled.

TRADE OUTCOME READY FOR INPUT

Net P&L per unit—After modeled entry and exit costs. Without a quantity, values are per 1 asset unit.

Gross P&L per unit—Before trading fees; after the assumed execution slippage.

Total fees per unit—

Net return on entry notional—Net P&L ÷ modeled entry notional.

Break-even quoted exit—Exit price required for zero net P&L at the selected costs.

Trading P&L linear model v1 · All amounts are in the entered quote currency. Leverage only changes indicative margin. Single entry/exit, no futures funding, loan interest, taxes, liquidation or inverse COIN-M settlement. Educational tool, not investment advice.

HOW TO READ YOUR RESULTS

Gross gain is not take-home profit.

Say you buy 2 units at $100 and sell them at $110. Your gross P&L is $20. If you pay 0.1% on entry ($0.20) and 0.2% on exit ($0.44), your net P&L is $19.36. Trading costs reduce the result even when the price moves in your favor.

Linear net P&L = (exit fill − entry fill) × quantity − entry fee − exit fee (long)
For a short: reverse the price difference.

Break-even quoted exit is the exit price needed to cover both fees and modeled slippage. It is not necessarily equal to your purchase price.

The net return on entry notional is a trade return measured against its full entry value. A second percentage, return on indicative margin, applies only if you choose leverage. A bigger percentage on margin does not imply a safer trade.
