This calculator uses an MT5-style single-position model: used margin is lots × contract size / leverage in base currency, then converted to the account currency. Stop-out price is estimated from the loss room between balance and stop-out equity. Thresholds are user inputs because broker rules differ.
How it works
What this calculates
This is an educational single-position estimate of the price where equity would reach a selected stop-out threshold. It also shows the margin-call equity level. It is not a broker rulebook and it does not model multiple open positions.
The formula
used margin base = lots × contract size ÷ leverage
used margin account = used margin base × rate(base to account)
equity call = call level% × used margin account
equity stop-out = stop-out% × used margin account
max loss = balance - equity stop-out
loss pips = max loss ÷ (pip value per lot × lots)
liquidation price = entry - direction × loss pips × pip size
Worked example - EUR/USD long
Balance $7,000, 1:25 leverage, long 1 standard lot EUR/USD at 1.195, USD account, 50% stop-out. Used margin is 100,000 / 25 × 1.195 = $4,780. Stop-out equity is 50% × 4,780 = $2,390. Loss room is 7,000 - 2,390 = $4,610. At $10 per pip, that is 461 pips, so the estimated stop-out price is 1.14890.
Important limits
- Margin call, stop-out and maintenance margin are not the same thing. The threshold percentages are broker parameters, so this tool makes them editable instead of hard-coding any broker's line.
- The closed form is single-position only. It is a useful approximation when this is the only open position. Multiple positions require account-level equity, total used margin and floating P&L.
- Cross-currency conversion must be explicit. If the account currency is neither base nor quote, both base-to-account and quote-to-account rates are needed. Missing rates should stop the calculation, not silently default to 1.0.
- Account-currency margin can move with price. When conversion rates change, a static closed-form estimate can drift from the broker's real-time engine.
