The essentials in 30 seconds
- In EUR/USD, EUR is the base currency and USD is the quote currency.
- One pip in EUR/USD is normally USD 0.0001 per euro.
- In the standard forex convention, one standard lot is 100,000 units of the base currency.
- More leverage lowers illustrative margin for the same position; it does not change the money lost or gained per pip.
- Actual costs can include the spread, commission, financing and currency conversion.
What EUR/USD means
An illustrative EUR/USD rate of 1.1000 means one euro is worth US$1.10. EUR, the first currency, is the base currency. USD is the quote currency. The rate tells you how many dollars correspond to one euro.
If the rate rises from 1.1000 to 1.1025, the euro has strengthened against the dollar. A simplified long EUR/USD position benefits before costs; a short position reacts the other way.
A pip measures movement; a lot sets the scale
A pip in EUR/USD is usually 0.0001. A rise from 1.1000 to 1.1025 is 25 pips. Some platforms show a fifth decimal place; that smaller increment is one tenth of a pip.
A standard lot is conventionally 100,000 units of the base currency. For EUR/USD, that means EUR 100,000. A mini lot is 10,000 units and a micro lot is 1,000. Check the provider’s contract specification rather than assuming every product uses these sizes.
Pip value · 1 standard lot
EUR 100,000 × USD 0.0001 per EUR = USD 10 per pip. At the fixed illustrative rate of 1.1000, this is about EUR 9.09. For a 0.1 lot, divide both figures by ten.
Change the size and see what moves
First change only leverage: margin changes, while the pip value stays the same. Then change lot size: the money amount per pip changes too. The calculator holds the illustrative reference rate constant.
Hypothetical EUR/USD example · reference rate USD 1.1000 per EUR · EUR account · assumed long position.
- Position notional
- €100,000.00 = US$110,000.00
- Pip value
- US$10.00 ≈ €9.09
- Illustrative required margin
- €3,333.33
- Price effect before costs
- US$250.00 ≈ €227.27
- Hypothetical spread effect (1.2 pips)
- US$12.00 ≈ €10.91
Margin = notional ÷ leverage. Price effect = pips × pip value. EUR amounts use the fixed 1.1000 reference rate; actual conversion can differ. The spread is shown separately, without commissions, financing, slippage or tax. The leverage choices do not imply product eligibility.
A 25-pip move in numbers
At one standard lot, 25 pips × USD 10 per pip = USD 250 before costs. At 1.1000 dollars per euro, that is approximately EUR 227.27. A 25-pip move against the position has the same magnitude with a negative sign.
For 0.1 lot, the pip value is USD 1, so 25 pips correspond to USD 25 before costs. The change comes from position size, not the margin requirement.
Calculate margin: collateral, not purchase price
The position’s nominal value is EUR 100,000. At an assumed 30:1 leverage ratio, the simple initial-margin model gives EUR 100,000 ÷ 30 = EUR 3,333.33. At 10:1, the same position would require EUR 10,000.
This is collateral, not a fee or a cap on losses. Actual margin depends on the instrument, broker, client classification and jurisdiction. Account protections and close-out rules also depend on the applicable product and regulatory framework.
What the trade actually costs
The spread is the difference between bid and ask. If an illustrative one-standard-lot position pays an effective 1.2-pip spread, the initial price effect is 1.2 × USD 10 = USD 12, approximately EUR 10.91 at the fixed reference rate. This is an example, not a provider quote.
Depending on the product and provider, there may also be a commission, overnight financing, currency conversion, slippage or other charges. The margin remains separate from these costs. Compare the relevant product documents before using a quoted figure.
Further detail: show assumptions and context
With a position of N euros and a EUR/USD pip increment of 0.0001 dollars per euro, the pip value in USD is N × 0.0001. Converting it to an EUR account uses the relevant USD/EUR rate at the time; the fixed 1.1000 rate above is a teaching assumption.
Leverage changes required collateral for a given notional amount. It does not change the underlying pip-value formula. Real products may use different margin tiers, contract sizes, financing methods and liquidation rules.
