Forex Profit and Loss Calculator (GBP)

How entry and exit set the result

Entry and exit set the pip move, and the pip move times pip value sets the money: on the worked trade above, 40 pips at £3.71 a pip is £148.41. Select the pair and direction, enter your entry and exit prices, the size in lots, and your account currency, and the result is the move in pips and its value in pounds (or dollars or euros), labelled profit or loss. Prices are hypothetical as readily as historical: enter a planned entry against a target, then against a stop, and you have both sides of the trade before taking it.

Used that way, the calculator turns a chart level into a reward-to-risk ratio in money. A target worth £148.41 against a stop risking half that is a 2:1 trade whatever the pair. Comparing money outcomes across pairs beats comparing pip counts, because pip values differ by pair and account currency.

The profit and loss formula

P/L = pip move x pip value, where the move is (exit - entry) / pip size for a buy and (entry - exit) / pip size for a sell. Pip size and the quote-to-account conversion are the pip value calculator's half of the sum, including the JPY convention and the per-pair figures; this page supplies the move and multiplies the two.

The conversion step is where GBP-account results differ from the dollar figures most calculators assume. A US$200 win is not £200; at the current rate it is £148.41. All figures on this page use the dated rates shown in the results panel.

What the result deliberately excludes

The figure is price P/L only. It excludes three costs:

• The spread crossed at entry and any per-lot commission. Both are measurable. On the worked trade above, the two together come to £2.21 at Axi, the cheapest of the 12 brokers we rank on raw accounts, which is about 1.5% of the £148.41 gross.
• Overnight financing, left out because it varies by broker, direction and day of the week (most firms charge one day at triple rate to cover weekend settlement), so any single assumed figure would be invented. Your broker's published financing schedule is the only honest input for held positions.

This page draws the exclusion line at a single trade. Our broker cost calculator draws the same line at monthly aggregate, ranking 12 of the 26 brokers we test on raw accounts and 23 on standard, and the lowest commission broker guide breaks down the per-lot charges behind it.

Where sizing is decided instead

This calculator prices a position you have already sized; choosing that size is the position size calculator's job, which works back from your risk percentage and stop distance. Our CFD trading examples run the same maths through a full long and a short trade, and our drawdown guide shows how consecutive losses compound.
