Leverage and margin: how much of the trade is yours
What you learn in 3 minutesThis lesson shows what leverage and margin cost you in naira, using EUR/USD at 1.0850 as the example. You will see how the same position needs very different amounts of your own money at different leverage settings. You will also learn why margin is not a fee, but money locked while the trade is open.
Margin on one standard lot at two leverage levels
| Step | Amount | Note |
|---|---|---|
| Position size | 1 standard lot EUR/USD | One standard lot is 100,000 units of the base currency, EUR. |
| Exchange rate used | 1.0850 | This is the EUR/USD price in the example. |
| Position value in USD | $108,500 | 100,000 units multiplied by 1.0850. |
| Position value in naira | ₦162,750,000 | Converted at an assumed rate of ₦1,500 per US dollar. Your broker's rate will differ. |
| Margin required at 1:30 | ₦5,425,000 | ₦162,750,000 divided by 30. |
| Margin required at 1:500 | ₦325,500 | ₦162,750,000 divided by 500. |
The broker may round the margin figure, add a small buffer, or quote the margin in US dollars and convert at its own rate. Margin requirements can also change before weekends and news events.
The mistake people make here
The common mistake is to treat high leverage as free extra money and open a position far larger than the account can support. Leverage does not change the size of a loss or a gain on a position; it only changes how much of your own money is locked as margin. If the trade moves against you, the loss is calculated on the full position value, not on the margin. A safer approach is to decide the largest loss you are willing to take in naira first, then choose a position size that keeps that loss small relative to your balance.Check yourself
At EUR/USD 1.0850 and a conversion rate of ₦1,500 per dollar, what is the margin in naira for one standard lot at 1:100?
Position value is 100,000 × 1.0850 = $108,500. In naira that is $108,500 × ₦1,500 = ₦162,750,000. Margin at 1:100 is ₦162,750,000 ÷ 100 = ₦1,627,500.
One pip on one standard lot of EUR/USD is 10 units of the quote currency. At the same conversion rate, what is one pip worth in naira?
One pip is 10 US dollars. Converted at ₦1,500 per dollar, 10 × ₦1,500 = ₦15,000. This value changes when the exchange rate changes.
