The short answer
Exposure is the notional size of the position. Required margin is the amount the provider requires to support it. Leverage describes a ratio between exposure and an amount supporting that exposure. Price-loss risk depends on the size and adverse price movement, plus relevant costs.

Four quantities that answer different questions
These quantities are related but cannot be substituted for one another. A small margin requirement does not mean the position has a small cash sensitivity. A stop-loss calculation does not establish that enough free margin exists to place the order.
Broker entity, instrument, account classification and exposure tiers can change margin rules. Every rate below is illustrative, not an offer of a particular leverage limit.
Calculate an illustrative margin requirement
Assume a linear position worth USD 20,000 and a flat margin requirement of 5%. Required margin is 20,000 × 0.05 = USD 1,000. The corresponding exposure-to-required-margin ratio is 20,000 ÷ 1,000 = 20:1.
Required margin = notional exposure × margin rate
Maximum leverage implied by a flat rate = 1 ÷ margin rate
This simple model excludes tiers and conversions. If exposure and account currency differ, convert consistently using the provider's rules. For a tiered schedule, calculate each portion at its applicable rate rather than multiplying all exposure by the lowest advertised rate.
Account leverage and margin level use other denominators
Now suppose account equity is USD 5,000, this is the only position, and used margin is USD 1,000. Effective account leverage is 20,000 ÷ 5,000 = 4:1. That differs from the 20:1 leverage implied by the position's margin requirement.
| Measure | Calculation | Result |
|---|---|---|
| Free margin | Equity − used margin | 4,000 |
| Margin level | Equity ÷ used margin × 100 | 500% |
| Effective leverage | Exposure ÷ equity | 4:1 |
Providers can use different account measures or labels. Do not divide by zero used margin to manufacture a finite margin level. Equity changes with open profit/loss, and used margin may also change with price, conversion rates or provider rules.
Why margin does not cap the loss
For the simplified USD 20,000 linear exposure, a 1% adverse move corresponds to approximately USD 200 of price loss before costs. The cash sensitivity comes from the exposure, not the USD 1,000 margin requirement. Gaps and financing can add to the outcome.
Margin closeout rules are provider-specific and do not guarantee a chosen exit price. Check the current rules, including how multiple positions and hedges are handled, rather than assuming a universal margin-call percentage.
Use position sizing to model a price-loss budget, and separately check the broker's margin requirement. The stop-distance guide explains how a price assumption becomes a pip distance. Neither resource checks account eligibility or sends an order.

Lesson 4 checkpoint
Put the reading into practice
Work it through
For hypothetical USD 20,000 exposure and a 5% margin requirement, calculate required margin. List two reasons a realised loss could differ from that amount.
