To use the trading calculator below, choose a market, leverage and trade size, then calculate P&L over a selected period.
Note: the Capital.com CFD trading calculator doesn’t include spreads, overnight funding or other applicable charges. These costs can reduce profits or increase losses. It also doesn’t calculate the equity-to-margin ratio, which you would need to monitor if you decide to trade CFDs.

A larger quantity increases the deal size, which means the same price move can result in a larger hypothetical profit or loss, depending on its direction.
Maximum leverage varies by market and can differ by country or region.
The opening and closing dates must both fall within the previous 30 days.
The calculator shows three results: deal size, margin required and P&L.
View P&L for the selected period without working through the formulas manually. Trading charges are not included.
See how different trade size settings can affect P&L. Adjust leverage to see how it changes the required margin.

A CFD calculator uses historical prices and your chosen market, trade size, leverage, direction and dates to calculate hypothetical P&L and margin. The Capital.com calculator uses market data from the previous 30 days.
A CFD calculator can help illustrate how trade size, leverage and direction affect hypothetical P&L and margin using historical prices. It’s a demonstration tool and doesn’t indicate how a future trade will perform.
Yes. The calculator can show results for long and short positions using the same historical prices. For a long position, a higher closing price results in a profit and a lower closing price results in a loss. For a short position, a lower closing price results in a profit and a higher closing price results in a loss.
The Capital.com CFD calculator applies its formulas to your inputs and historical market data. The result is hypothetical and excludes spreads, overnight funding and other applicable charges, so it may differ from the result of a live trade. Past performance is not a reliable indicator of future results.
CFD P&L depends on the difference between the opening and closing price and the traded quantity.
For a long position:
P&L = (closing price − opening price) × traded quantity
For a short position:
P&L = (opening price − closing price) × traded quantity
This is before spreads, overnight funding and other applicable charges.
Margin is the amount required to open a leveraged position. The calculator works it out by dividing the deal size by the leverage ratio. For example, a $1,000 deal size at 5:1 leverage requires $200 in margin. The calculator does not show the equity-to-margin ratio, which needs to be monitored separately while positions are open.
Leverage changes the margin required for a given trade size, but not its P&L. P&L is calculated on the full deal size. For example, increasing the leverage on the same hypothetical position reduces the margin required, while the calculated P&L remains unchanged.
The Capital.com CFD calculator includes a selection of forex pairs, indices, commodities, shares and ETFs. Examples include EUR/USD, the US 500, gold and Apple shares.
