What to know before sizing EURUSD
EUR/USD is quoted as dollars per euro, so the quote currency is the dollar. For a USD account that makes it the simplest pair to size: a pip (0.0001) is worth $10 per standard lot whatever the price, and $1 per 0.1 lot. The calculator above is pre-set to that case.
The pair trades almost around the clock from Monday to Friday and is deepest when London and New York overlap. Rate decisions from the ECB and the Federal Reserve, and US jobs and inflation data, are the usual sources of sudden moves. A stop that looks safe in a quiet Asian session can be one data release away from being hit, so look at how far the pair travelled around past releases before you choose the pips in your stop.
Watch for
- Some brokers show a fifth decimal. That digit is a pipette, a tenth of a pip: in 1.08507 the pip digit is 0 and the pipette is 7.
- If your account is in euros, the pip value is no longer fixed. It becomes $10 divided by the price (about €9.22 at 1.0850), because the dollars have to be converted back.
- The spread is part of the cost. A 1.0 pip spread on one standard lot costs $10 the moment you enter, which matters most when your stop is only 10 to 15 pips.
EURUSD contract specifications (example)
| Instrument | Euro / US dollar (EURUSD) |
|---|---|
| Contract size (example) | 100,000 EUR per standard lot (0.01 lot = 1,000 EUR) |
| Value of 1 pip per 1 lot | $10.00 at the example price |
| Minimum size and step (example) | 0.01 lot at most retail brokers, in steps of 0.01 |
| Example price used | 1.0850 |
| Currency handling | Quote currency is USD, so no conversion is needed for a USD account. |
Example specification. Brokers differ: confirm the contract size, minimum size and step in your platform's contract specification before you size a real trade.
Worked examples for EURUSD
Every number below is computed with the same formulas as the calculator, at the example prices shown, for a USD account.
Value of one pip at different sizes
At the example price of 1.0850, the money value of one pip on EURUSD for a USD account:
Sizing a trade on EURUSD from your risk
Account $10,000, risk 1% ($100), stop 20 pips. Each pip is worth $10.00 per lot, so the exact size is 100 ÷ (20 × $10.00) = 0.5 lots. Rounded down to a tradable size that is 0.50, and the real risk is $100.
A small account: micro lots do the work
A $500 account risking 1% has $5 to lose. With a 20 pip stop and $10.00 per pip per lot, the exact size is 0.025 lots. Brokers usually allow steps of 0.01 lot, so it rounds down to 0.02 lot, and the real risk is $4.00, never above the limit. A 0.1 lot trade would risk $20.00, more than the whole budget.
The math behind the numbers
size = (balance × risk %) ÷ (stop in pips × value of 1 pip per lot)
round down to a multiple of 0.01
position value = size × contract × price (converted to USD)Same formulas as the pip value and position size calculators (EURUSD numbers above are examples at the price shown). Rounding down keeps real risk at or below your limit.
To run your own numbers for another currency or contract, use the lot size calculator, the pip value calculator or the position size calculator.

How much to risk per trade is a separate question, covered in how much to risk per trade, and the step-by-step is in how to calculate position size.
EURUSD questions
Does the pip value of EUR/USD change when the price moves?
Not for a USD account. The pip is paid in dollars, so one standard lot is $10 per pip at 1.05, 1.08 or 1.15. It does change in your own currency if your account is in euros, pounds or anything else, because the dollars must be converted.
What is a lot of EUR/USD?
A standard lot is 100,000 euros, a mini lot 10,000 and a micro lot 1,000 (0.01 lot). Check the minimum size and the step your broker allows in its contract specification.
How many pips should my EUR/USD stop be?
There is no universal number. Put the stop where your trade idea is wrong, measure that distance in pips, and let the position size follow from your risk. A common mistake is shrinking the stop to fit a bigger lot size.
How much is one pip worth on EURUSD?
For a USD account, one pip on 1 lot is about $10.00 at the example price of 1.0850, and $1.00 on 0.1 lot. Brokers differ, so confirm the contract size before you rely on it.
What size should I trade on EURUSD with $10,000?
It depends on your risk and stop, not on the account alone. With 1% risk and a 20 pip stop the example size is 0.50 lots, which risks $100. Change the stop and the size changes with it. This is arithmetic, not advice.
