Complete Guide to Forex Margin Calculations
What Is Forex Margin?
Forex margin is the amount of money your broker requires you to deposit as collateral to open and maintain a leveraged trading position. It is not a fee or cost — it is a good-faith deposit that is temporarily set aside while the trade is open.
Think of it as a security deposit: your broker holds a portion of your account balance as collateral, returning it when you close the trade. The remaining balance is your free margin, which you can use to open additional trades.
How to Calculate Required Margin
Formula:
Required Margin = (Trade Size × Base Currency Rate) ÷ Leverage
Where:
- Trade Size = Lot Size × Number of Lots (e.g., 100,000 for 1 Standard Lot)
- Base Currency Rate = Exchange rate of the base currency vs. USD
- Leverage = Your broker's leverage ratio (e.g., 100 for 1:100)
Key Margin Terms Explained
Required Margin
The minimum deposit your broker needs to open your trade. Calculated as a percentage of the total trade value (e.g., 1% margin = 1:100 leverage).
Free Margin
Your account balance minus the used (required) margin. This is the amount available to absorb losses or to open new trades.
Margin Level (%)
Margin Level = (Balance ÷ Used Margin) × 100. Brokers typically issue margin calls when this falls below 100% and stop-outs below 50%.
Margin Call
A notification from your broker that your margin level has fallen too low. If it drops further, trades may be automatically closed (stop-out).
Margin Requirements by Leverage
| Leverage | Margin % | Margin for 1 Standard Lot (EUR/USD ~$108,000) |
|---|---|---|
| 1:10 | 10% | $10,800 |
| 1:20 | 5% | $5,400 |
| 1:50 | 2% | $2,160 |
| 1:100 | 1% | $1,080 |
| 1:200 | 0.5% | $540 |
| 1:500 | 0.2% | $216 |

Understanding Lot Sizes
| Lot Type | Units | Pip Value (EUR/USD, USD Account) | Best For |
|---|---|---|---|
| Standard | 100,000 | $10 | Experienced traders |
| Mini | 10,000 | $1 | Intermediate traders |
| Micro | 1,000 | $0.10 | Beginner traders |
| Nano | 100 | $0.01 | Practice / very small accounts |
Margin Management Tips
Tip 1: Always keep your margin level above 200% to give yourself a comfortable buffer against adverse price moves.
Tip 2: Never risk more than 1–2% of your account balance on a single trade. Use lot sizes that keep your pip risk within this limit.
Tip 3: Higher leverage increases both potential profits and losses. Choose leverage appropriate for your strategy and risk tolerance — not just the maximum available.
Tip 4: Use stop-loss orders on every trade. Your stop-loss should be set so that the maximum loss is within your per-trade risk tolerance (e.g., 1–2% of balance).
