Leverage multiplies both gains and losses against a small margin deposit; the higher the leverage, the smaller the move needed to wipe that margin out.

How to use the Leverage Calculator
Using the leverage calculator takes only a few seconds:
- Enter your figures in the leverage calculator above — the fields are filled with an example you can replace.

- Change any input to compare scenarios before you commit to the trade.
Leverage formula & example
The leverage formula is: Leverage = position size ÷ margin (e.g. $10,000 ÷ $1,000 = 10:1).
A $20,000.00 position at 5:1 needs $20,000.00 ÷ 5 = $4,000.00 margin. A 20.0% adverse move wipes that margin out.
When to use the Leverage Calculator
Reach for the leverage calculator whenever you’re planning a trade and need to know your leverage in advance. Running the number first keeps your decisions consistent and stops a single trade from doing outsized damage to your account. Traders who make this a habit — checking before every entry — are the ones who protect their capital over the long run.
Why use a leverage calculator?
Doing leverage by hand is slow and error-prone — a misplaced decimal or a forgotten fee can turn a winning plan into a losing one. The leverage calculator removes that risk: it applies the correct formula every time, updates the moment you change an input, and lets you test several scenarios in seconds.
That speed matters in live markets. When a setup appears you can size it, check the reward against the risk, and act before the opportunity passes — without second-guessing your arithmetic.
