How Forex Margin Is Calculated
For a conventional EUR/USD trade in a USD account.
| Required margin | Position value in USD ÷ Leverage factor |
|---|---|
| Position value in USD | EUR units traded × EUR/USD price |
Contract sizes and margin settings can differ; some CFDs use fixed margin percentages. Margin is collateral, not the maximum potential loss or the total notional position value.
Worked example: Required margin
A 0.10-lot EUR/USD position at 1.11176, using 1:100 leverage in a USD account.
Required equity
$111.180.10 lot · 1:100 leverage
- Position size
- 0.10 × 100,000 = 10,000 EUR
- Position value
- 10,000 × 1.11176 = $11,117.60
- Opening margin
- $11,117.60 ÷ 100 = $111.18 (rounded)
The unrounded margin is $111.176. This is the estimated equity required, not the maximum potential loss. The exchange rate is an illustrative input, not a guaranteed execution price.
How the Optional 50% Bonus Calculation Works
With the optional bonus setting enabled, the same $111.18 equity requirement is split between balance and credit.
Eligibility, caps and terms may apply. These figures do not establish that credit is available, usable for every instrument or withdrawable as cash. Check the current account conditions.
- Balance required
- $74.12
- Credit available
- $37.06
Illustrative split only: $74.12 + $37.06 = $111.18. This does not confirm entitlement to a bonus.
Choose the right margin tool
Required margin estimates collateral for a new position; free margin is equity not allocated to used margin. A margin call compares current equity with used margin and a warning threshold.
Frequently Asked Questions
How is forex margin calculated?
For a simplified forex position, convert its notional value into the account currency and divide by the leverage factor. Instrument-specific margin rates and account rules can change the actual requirement.
How much margin is needed for one EUR/USD lot at 1:100?
At a hypothetical EUR/USD price of 1.1000, one conventional 100,000-EUR lot has a notional value of $110,000. At 1:100 leverage, the simplified margin requirement is $1,100, before any additional instrument-specific conditions.
Is required margin the same as free margin?
No. Required margin is collateral estimated for a position; free margin is the account equity remaining after used margin. This calculator estimates the requirement for a proposed trade, not your account's total free margin.
Does the 50% deposit bonus apply to every FXGlory account?
No. Bonus availability and terms may depend on the account and applicable promotion. The checkbox models a possible credit split; it does not confirm entitlement to a bonus.
