Forex Profit Calculator
Enter your entry and exit, lot size and pip value, and this returns the pips gained, the dollar result in your account currency, and what the spread cost you on the way in.
The calculation
Pips = (exit − entry) ÷ pip size, signed by direction. P&L = pips × pip value per lot × lots. The default is a 68-pip winner on one standard lot of EUR/USD: $680 gross, $8 of spread, $672 net.
Spread is a real cost and it is charged immediately
Every forex position starts at a loss equal to the spread, because you buy at the ask and the position is marked at the bid. A 0.8-pip spread on one lot is $8 — small against a 68-pip winner, and very large against a 5-pip scalp, where it is 16% of the target.
Spreads widen. The 0.8 pips quoted on EUR/USD during London hours can be 3 pips at the Asian open and far worse in the seconds around a data release. Systems tested against typical spreads and traded at news-time spreads do not perform as tested.
Swap is the cost this calculator omits
Hold a position past the daily rollover and you pay or receive swap, based on the interest-rate differential between the two currencies. On a carry-positive pair it is income; on a carry-negative one it is a daily fee that compounds quietly. Over a multi-week hold, swap can exceed the spread by an order of magnitude. Check your broker's swap table for the pair before assuming a long hold is free.
Getting pip value right first
Everything above scales off pip value, which is $10 per standard lot only when the quote currency is your account currency. For JPY pairs and crosses, compute it on the pip value calculator and bring the number back here.
Checking the arithmetic against a contract
CME's Euro FX future is 125,000 euro with a minimum fluctuation of 0.00005, worth $6.25 per contract.[1] Any pip value your broker quotes should reconcile to the same units-times-move calculation.
The number is the easy part
Everything above is arithmetic, and anyone opening this page gets the same answer. What no calculator can settle is whether you took the trade on these terms, or are describing — afterwards — the version of it that worked out.
That is what a trade recorder is for: the trade committed before it resolves, timestamped and sealed on the spot, on a Merkle-anchored log a stranger can check without kappi's cooperation. The plan you typed here stops being a plan you remember having. $15/month, no free tier.

Frequently asked questions
How do I calculate forex profit in pips?
Subtract entry from exit, divide by the pip size (0.0001, or 0.01 on JPY pairs), and flip the sign for a short. Multiply by pip value and lot size for the money result.
Is the spread charged on entry or exit?
Effectively on entry — you buy at the ask and are marked at the bid, so the position opens down by the spread. This calculator charges it once.
What is swap or rollover?
The interest-rate differential paid or received for holding a position past the daily rollover. It is not included here and can dominate the economics of a long hold.
Why is my broker's P&L slightly different?
Usually pip value conversion at a different rate, a wider fill than the price you recorded, or swap charges on an overnight hold.
