From lots to gross P/L
Direction × (Exit − Entry)
× Lots × Units per lot
Direction is +1 for Buy and −1 for Sell. The result is in the quote currency. Multiply it by the exit conversion rate to express gross P/L in your account currency.

Model assumptions ↗How to calculate forex profit and loss
Start with the price movement in the pair’s quote currency, convert it at the scenario exit, then subtract the costs you entered.
From gross to net
Gross P/L − (Commission per lot
× Lots) − Fixed fees
Commission covers opening and closing together. Fixed position fees apply once. Costs increase a loss as well as reduce a profit. Spread already reflected in execution prices is not added again.
Two conversion contexts
When your account matches the quote currency, no conversion is needed. When it matches the base currency, the entry factor is 1 ÷ Entry and the exit factor is 1 ÷ Exit. For a third currency, enter both rates or explicitly assume an unchanged manual rate.
A price that covers your costs
For a constant exit factor k, model breakeven is Entry + Direction × Costs ÷ (Units × k). For a base-currency account it is Entry ÷ (1 − Direction × Costs ÷ Units). The first permitted tick at or beyond that price must also cover costs. A positive price may not exist.
How pip value is calculated
A pip measures price distance. Its monetary value depends on volume and the reference conversion rate.
Volume determines the value
Pip value at entry = Lots × Units per lot × Pip size × Entry conversion rate. For these pairs, a pip is 0.01 when the quote currency is JPY and 0.0001 otherwise. The smaller quoted tick is one tenth of a pip.
The entry value is a reference estimate. If the exit conversion rate differs, multiplying the whole move by the entry pip value will not reproduce the exact P/L.
Standard lot example
| Lots | Base-currency units |
|---|---|
| 1.00 | 100,000 |
| 0.10 | 10,000 |
| 0.01 | 1,000 |
Check your broker’s contract size and volume grid. This calculator rejects a non-permitted lot size rather than changing your volume.
How forex margin is estimated
Margin is an estimate of collateral for the entered volume. It is not the amount you can lose.
Leverage estimate
Estimated margin = Units ÷ Leverage × Entry price × Entry conversion rate. At 1:100, 20,000 EUR at EUR/USD 1.10000 requires an estimated $220 for a USD account.
Entered margin per lot
If you know the required margin for one lot in your account currency, enter it directly. Margin = Lots × Entered margin per lot. No additional leverage division or currency conversion is applied.
Keep P/L separate
Changing leverage does not change P/L or pip value for the same volume and prices. Actual requirements can depend on broker rules, tiers, existing positions and available funds, which this tool does not assess.
Forex calculation examples
Illustrative prices and contract terms, not live quotes or a broker offer.
EUR/USD with round-trip costs
Buy 0.20 lots with 100,000 units per lot, enter at 1.10000 and exit at 1.10500. A 50-pip move produces $100 gross in a USD account. At $7 commission per lot, costs are $1.40 and net profit is $98.60. Entry pip value is $2; estimated margin at 1:100 is $220.
Model and executable breakeven are both 1.10007. These values use zero fixed fees.
USD/JPY in a USD account
Buy 0.20 lots at 150.000 and exit at 151.000. Gross profit is 20,000 JPY, or about $132.45 using 1 ÷ 151 at exit. Entry pip value is about $1.33 using 1 ÷ 150. Estimated margin at 1:100 is $200.
Different entry and exit rates
For EUR/GBP in a USD account, 0.20 lots from 0.86000 to 0.86500 produces 100 GBP. At an exit factor of 1.30 USD per GBP that is $130 gross; an entry factor of 1.25 gives $2.50 entry pip value and $215 margin at 1:100.
Assumptions and limitations
One linear forex trade
The model covers 28 currency pairs with editable generic contracts. It does not include swaps, tiered margin, margin call, liquidation, hedging or portfolio exposure.
Your execution assumptions
Use planned fill prices: Ask entry and Bid exit for Buy, Bid entry and Ask exit for Sell. Include any spread or slippage assumption in those prices. Additional spread is not charged automatically.
Rates and specified costs
Third-currency rates are manual inputs. Linking them assumes an unchanged rate; a base-currency account instead always converts at the corresponding entry or exit price. Only entered round-trip commission and fixed fees are deducted.
Scenario estimates
Educational calculations, not investment advice. Results use your entered prices, costs and conversion rates. Margin is an estimate, not a loss limit or a guarantee that a trade can be opened. Live execution, swaps and portfolio exposure are not modeled.

Frequently asked questions
What does this forex calculator calculate?
It estimates gross and net P/L, pip value at entry, margin and breakeven for one entered forex trade. You choose the volume and assumptions.
How do I calculate forex profit or loss?
Multiply the entry-to-exit price change by base-currency units and +1 for Buy or −1 for Sell. Convert the quote-currency result at the scenario exit rate and subtract entered costs.
What is the difference between gross and net profit?
Gross P/L measures the price outcome after currency conversion. Net P/L deducts your full round-trip commission per lot multiplied by lots, plus fixed fees once for the position.
How is pip value calculated?
Multiply pip size by the position in base-currency units and the entry conversion factor. Pip size is 0.01 for JPY quote pairs and 0.0001 for other supported pairs.
Why does account currency change the result?
The pair produces P/L in its quote currency. Your account may require conversion. Pip value and leverage margin use entry conversion; P/L uses exit conversion.
Does leverage change my profit or loss?
For the same volume and execution prices, leverage changes the estimated margin, not the price P/L or pip value.
Is margin the most I can lose?
No. Margin is collateral, not a loss limit. Losses and actual collateral requirements can differ from this scenario. Available funds and liquidation are not modeled.
Are spread, commissions and swaps included?
Spread is reflected in the execution prices you enter. The calculator deducts entered round-trip commission and fixed fees. It does not add spread again or calculate swap automatically.
Can I use different conversion rates at entry and exit?
For a third account currency, turn off Use same conversion rate at exit and enter both rates. For a base-currency account, 1 divided by the corresponding entry or exit price is used automatically.
Why is the breakeven price different from entry?
Trading costs must be recovered. The model also accounts for conversion that depends on the exit price. The theoretical breakeven can differ from the first permitted price tick that covers costs.
How do I choose a lot size from my risk?
Use the Position Size Calculator to size volume from capital, a risk budget and stop loss. This forex calculator uses the volume you enter.
Are these live quotes and broker-specific margins?
No. Prices and rates are entered manually and the contract profiles are generic and editable. Check your broker’s specifications and requirements.
Are my inputs stored or shared?
Calculations run in your browser without sending inputs to a backend or saving them in local storage. Share explicitly creates a link containing your inputs and settings; anyone receiving it can read them.
