How to Calculate Lot Size for EURUSD: Position Sizing and Pip Value
BY TIOmarkets
|March 22, 2026Calculating your lot size before entering a EURUSD trade is a foundational risk management step. The lot size you choose determines your pip value, your margin requirement, and how much you stand to gain or lose on each pip move.
This guide covers the EURUSD contract size at TIOmarkets, how to calculate pip value in USD, how margin is worked out, and how to apply a position sizing formula to find the right lot size for any defined risk amount.
EURUSD Contract Size
At TIOmarkets, one standard lot of EURUSD represents EUR 100,000 of the base currency. The minimum trade size is 0.01 lots, which equals EUR 1,000. Positions can be sized in increments of 0.01 lots between those two points, allowing precise control over your exposure at any account size.
The three most common lot sizes are the standard lot at 1.0 (EUR 100,000), the mini lot at 0.1 (EUR 10,000), and the micro lot at 0.01 (EUR 1,000). Most retail traders use mini or micro lots to keep pip values and margin requirements proportionate to their account balance.
EURUSD Pip Value
EURUSD is quoted with USD as the quote currency. This means the pip value is denominated directly in USD, without any additional conversion step for traders holding USD-denominated accounts.
A pip on EURUSD is the fourth decimal place of the exchange rate, equal to 0.0001. For a standard lot, the pip value is 0.0001 multiplied by 100,000, which equals USD 10. For a mini lot, the pip value is USD 1. For a micro lot, it is USD 0.10.
These figures apply to accounts held in USD. If your account is denominated in a different base currency, the USD pip value will be converted into your account base currency at the prevailing exchange rate at the time of the trade.
Because USD is the quote currency, the pip value in USD does not change as EURUSD moves. A pip on a standard lot is always worth USD 10 whether EURUSD is trading at 1.0500 or 1.1500. This makes EURUSD one of the most straightforward pairs for pip value calculations, and position sizing formulas produce consistent results without needing rate adjustments.
Margin Requirement for EURUSD
TIOmarkets applies a 1% margin requirement to EURUSD. To open a position, you need at least 1% of the total notional value of the trade available as margin in your account. Margin requirements are subject to change depending on market conditions and applicable regulatory requirements.
The notional value of a EURUSD position is calculated in USD. For a standard lot, the notional value is EUR 100,000 converted to USD at the current exchange rate. If EURUSD is trading at 1.1000, the notional value is USD 110,000 and the required margin is USD 1,100. If EURUSD is at 1.1500, the notional value is USD 115,000 and the required margin is USD 1,150. The margin requirement in USD shifts as the exchange rate moves.
For a mini lot at 1.1000, the required margin is USD 110. For a micro lot at the same rate, it is USD 11.
If you are using the unlimited leverage feature on the Standard account with MT5, margin scaling applies based on your account equity. The 1% margin tier applies at equity levels of USD 5,000 to USD 19,999. Different tiers apply above and below that range. The unlimited leverage feature is available on the Standard account only and is not available on Raw or VIP Black accounts.
Position Sizing for EURUSD
Position sizing connects your lot size to a specific risk amount per trade. The standard approach is to define the maximum dollar loss you are willing to accept if your stop is triggered, then work backward from your stop distance to arrive at the correct lot size.
The formula is: lot size = (account balance x risk percentage) / (stop loss in pips x pip value per lot).
A worked example for a USD account: suppose you have a USD 10,000 account and you are willing to risk 1% per trade, which is USD 100. You plan to place a stop loss 25 pips from your entry on EURUSD. The pip value for a standard lot is USD 10.
Dividing USD 100 by 25 pips gives USD 4.00 risk per pip. Dividing USD 4.00 by USD 10 (the pip value per standard lot) gives 0.40 lots. You would trade 0.40 lots to keep your maximum loss on this trade at USD 100.
Because the pip value in USD is fixed for EURUSD, this calculation remains consistent regardless of where the exchange rate is at the time you place the trade. You do not need to recalculate for rate changes when using a USD account, which makes EURUSD one of the simplest pairs for applying a repeatable position sizing process.
Using TIOmarkets Calculators for EURUSD
TIOmarkets provides three online calculators to help you work out EURUSD trade parameters without manual arithmetic.
The pip value calculator lets you enter your account currency, the currency pair, and the number of lots. It returns the pip value expressed in your account base currency, including any conversion from USD if your account is not USD-denominated.
The margin calculator lets you enter the currency pair, your account currency, your leverage, and your lot size. It returns the exact margin required to open the position at the current rate.
The profit calculator lets you enter a currency pair, trade direction, entry price, exit price, and lot size. It returns the estimated profit or loss in your account currency, useful for planning reward-to-risk ratios before placing a trade.
