How required margin is worked out
- Position size is the base currency amount you control — lot size multiplied by number of lots.
- That amount is converted into your account currency at the current exchange rate.
- Leverage sets how much of that value your broker requires you to put up as margin.
Margin isn't a fee — it's collateral your broker holds
Avoid margin calls
Know your used margin upfront so a string of open trades doesn't quietly eat your free margin.
Compare leverage levels
See exactly how much less margin the same trade needs at 1:200 versus 1:50 before you decide.
Plan multiple positions
Check the margin for each pair you're considering so you can size a whole portfolio of trades sensibly.
Margin calculator — common questions
What's the difference between margin and leverage?+
Leverage is the ratio your broker offers (e.g. 1:100). Margin is the actual amount of money — in your account currency — that gets set aside to open a position at that leverage.
What happens if I don't have enough free margin?+
Your broker's platform won't let the trade open, or if your existing trades move against you enough to breach the margin requirement, you may face a margin call or automatic position closeout — check your broker's specific policy.
Does higher leverage mean lower risk?+
No — leverage changes how much margin a trade requires, not the size of the trade itself. Your pip value and total risk exposure stay identical regardless of leverage.
Is this the exact margin my broker will charge?+
This calculator uses indicative reference rates for learning purposes. Always check your broker's platform for the precise margin requirement before opening a live position.
