Margin trading lets you control larger positions with less capital. But leverage amplifies losses just as much as profits — making margin calculation essential for survival.
How Margin Works
When you trade on margin:
- You deposit a percentage of the position value (the margin)
- The broker lends you the rest
- You control the full position, profiting or losing on the entire amount
- You pay interest on the borrowed amount
Example
You want to buy $10,000 worth of stock with 20% margin:
- You deposit: $2,000 (20%)
- Broker lends: $8,000 (80%)
- Effective leverage: 5:1
A 10% gain yields $1,000 — a 50% return on your $2,000. But a 10% loss also costs $1,000 — a 50% loss on your margin.

Margin Level and Safety
Your margin level shows how healthy your account is:
Margin Level = (Account Equity / Used Margin) x 100%
- Above 200%: Healthy
- 100-200%: Caution zone
- Below 100%: Margin call territory
