Margin level & stop-out calculator.
Margin level is equity divided by used margin, times 100 — the percentage your broker uses to decide when to force-close positions. Enter your numbers to see your level and how far your equity is from the stop-out.
Thresholds and formulas vary by broker and instrument, and a margin call usually fires at a higher level first — check your broker’s terms.
Estimate only. Margin level = equity ÷ used margin × 100. Your broker's terms are the only authority.
The formula
Margin level % = (equity ÷ used margin) × 100. Stop-out equity = used margin × stop-out %. Room = current equity − stop-out equity.
Worked example
Equity $2,200 and used margin $2,000 give a 110% margin level. At a 50% stop-out, positions start closing once equity hits $1,000 — a $1,200 drop away.

Frequently asked
How is margin level calculated?+
Margin level % = (equity ÷ used margin) × 100. It falls when equity drops (losing trades) or when used margin rises (more or larger positions). Exact thresholds vary by broker.
What's the difference between a margin call and a stop-out?+
A margin call is a higher warning level where you usually can't open new positions and are expected to act; the stop-out is a lower level where the broker itself starts closing your positions.
What happens at the stop-out level?+
At or below the stop-out level the broker force-closes positions — typically the largest losing one first — until the account is back above the line. On crypto exchanges the equivalent is a liquidation against maintenance margin.
