Your true leverage — and the move that wipes equity.

What is the Effective Leverage Calculator?

The Effective Leverage Calculator is a risk tool that reveals your true leverage: how large your total open exposure is relative to your account equity, not the nominal leverage your broker offers. It answers 'how leveraged am I really right now, and what size of adverse move would wipe my equity?'

How to use it

  1. Enter Total open exposure ($) as the combined notional value of everything you have open.
  2. Enter Account equity ($) as your current account balance backing those positions.
  3. The calculator divides exposure by equity to give Effective leverage, and shows Equity as % of exposure as the flip side of that ratio.
  4. Read Adverse move that wipes equity as the theoretical percentage move against you that would reduce equity to zero, remembering it is an idealised figure.

How it's calculated

Effective leverage = total open exposure / account equity. Equity as a percentage of exposure = equity / exposure x 100, which is the inverse of the leverage figure. The adverse move that wipes equity = 1 / effective leverage (as a percentage) e.g. 11x effective leverage implies roughly a 9% adverse move to zero equity, ignoring frictions.

Frequently asked

What is effective leverage in trading?

Effective leverage is your total open exposure divided by your account equity. It reflects how leveraged you actually are across all open positions, which can differ sharply from your broker's headline leverage.

How does this leverage calculator find the move that wipes my account?

It takes the inverse of your effective leverage: at 10x effective leverage, a roughly 10% adverse move against your exposure equals your entire equity. It is a theoretical illustration of how thin your buffer is.

Is lower effective leverage always better?

Lower leverage means a larger adverse move is needed to wipe equity, giving more buffer, but this calculator does not judge what level is right for you or whether a strategy is sound.

Keep in mind: The wipe-out figure ignores margin calls, spreads and gaps: real accounts get stopped out before equity reaches zero, so treat it as an illustration of how thin your buffer is, not a literal survival threshold.
