Convert standard lots into units, notional exposure, estimated pip value, margin requirement, and stop-based price risk.
STEP-BY-STEP
How to use this tool
- Enter the standard-lot quantity you are evaluating.
- Confirm the exact units per standard lot in the broker’s symbol specification.
- Enter the current pair price and the account-currency pip value for one standard lot.
- Add the planned stop distance in pips.
- Enter the leverage ratio applied to that symbol and account.
- Review units, notional exposure, pip value, stop risk, and margin together.
- Verify every value in the broker or simulation-platform order preview before placing an order.
WORKED EXAMPLE
See the calculation in context
At 1.00 standard lot, a 100,000-unit contract, EUR/USD at 1.1000, and 50:1 leverage, the notional exposure is $110,000 and estimated margin is $2,200. At $10 per pip, a 25-pip stop estimates $250 of price risk before costs.
Calculation method
Position units = standard lots × units per standard lot. Notional exposure = units × current price. Pip exposure = standard lots × pip value per standard lot. Estimated margin = notional exposure ÷ leverage.
AVOID THESE ERRORS
Common mistakes
- Assuming one standard lot is always 100,000 units
- Assuming pip value is always $10
- Confusing notional exposure with the amount at risk
- Using account leverage when the symbol has a lower leverage cap
- Ignoring conversion, spread, commission, slippage, and swaps
- Using margin as a substitute for a stop-based risk plan
FREQUENTLY ASKED
Questions and answers
What is a standard lot?
In many forex products it represents 100,000 base-currency units, but the broker’s contract specification controls.
Is notional exposure the same as risk?
No. Stop distance, pip value, execution, and costs determine planned price risk; notional exposure describes the position’s market value.
Why can required margin differ?
Brokers can apply symbol-specific leverage, tiers, currency conversion, and additional margin rules.
