Profit & loss calculator

Gross P&L is pure price arithmetic: (exit − entry) × quantity, with the sign reversed for shorts. Everything else is cost, and it accrues whether or not the trade works out.

Commission is charged either as a flat fee per order or as a percentage of turnover, often with a minimum and a cap. Both sides count: entry and exit are two orders. **The spread** is the gap between bid and ask; it is charged once in full, because you buy at the ask and sell at the bid — it is never itemised, it hides inside the execution price.

Currency conversion hits every position not denominated in your account currency. The markup applies on both legs: once buying, once selling. At 0.25 % per conversion that is 0.5 % of turnover before the price has moved at all.

Financing starts as soon as the position is held overnight with borrowed money — CFDs, forex, and margin loans. It accrues on the full position value, not on your equity share, and it runs on calendar days, weekends included. That is why leveraged positions age badly: the price does not merely have to move, it has to move fast enough.

Return on capital committed is the more honest figure than absolute profit. Leverage shrinks the capital committed, not the risk: the same EUR 200 loss is a footnote against EUR 10,000 of capital and a fifth of the stake against EUR 1,000. The break-even price below shows how far the market has to travel before the position has covered its own costs.
