Margin Calculator
Work out the exact margin your broker needs to open any trade. Across forex, crypto, stocks, commodities and indices. Pulls the live price for your symbol, factors in account-currency conversion and your chosen leverage, then shows margin call distance so you know how much room the position has before it gets liquidated.
Why brokers ask for margin and what they really lock
Type a symbol to autofill the live price, choose your leverage, plug in trade size and account balance. Hit Calculate. The tool returns six panels of margin and risk insight, in this order.
1. Calculation Results
The top of the results panel surfaces the four numbers that matter on every open: Margin Required is the dollar amount your broker locks up to hold the position. Notional Value is the full size of the trade in your account currency (i.e. what you’re actually controlling). Margin % of Balance shows what fraction of your account is committed to this single trade. Sustainable accounts stay under 30%. Live Price is the price the calculator used to size the math, refreshed every minute. The calculator handles JPY pip math (0.01 vs 0.0001), cross-currency conversion when the quote currency doesn’t match your account currency, and broker-specific leverage caps automatically.
Calculation Results
live regime
Volatility is within normal range. Standard position sizing applies. You have 724 pips of headroom before the broker calls margin.
2. Volatility Intelligence
Margin is only half the picture. The other half is how much the price typically moves in a day relative to the room you have. CleaRank Pro unlocks the Volatility Intelligence card: 14-day ATR (real average true range, refreshed every few minutes), a volatility regime badge (Quiet / Normal / Elevated), the expected daily dollar impact at your current size, the distance in pips to a margin call, and a risk-adjusted size suggestion that caps the position at 2% account risk per ATR. The free embed shows you the panel as a preview so you can see what’s locked. Once unlocked, every recalc updates the volatility math in real time.
3. Margin Usage gauge
A horizontal bar coloured Safe (green, under 20% of your equity), Moderate (amber, 20–50%) and High (red, 50%+). Most blow-ups happen quietly because traders never look at this. A single 70% margin trade plus one normal pullback puts the account a few hundred pips from a margin call. The gauge updates every time you change leverage or trade size, so you can see exactly which combination of inputs pushes you out of safe territory before you open the position.
36.2% · Safe
MODERATE 20–50%
HIGH > 50%
5 scenarios
Liquidation triggers at a −8% move. Hard stop somewhere between −5% and −7% keeps the account alive.
4. Margin Call Stress Test
CleaRank Pro runs your live trade through five adverse-move scenarios (-1%, -3%, -5%, -8%, -12%) and shows what each one does to your margin level. The status column flags Safe → Watch → Danger → Margin Call → Stop Out so you can see exactly which size of move triggers the broker’s auto-liquidation. Most retail brokers liquidate at 50% margin level. A number nobody tracks until it’s too late. Run any setup through the stress test before opening, and you’ll know in advance whether a normal day’s move can survive the position.
5. Compare & Portfolio modes
The free Calculator mode handles one trade at a time. CleaRank Pro unlocks two extra modes you’ll use daily once you have it. Compare stacks two scenarios side-by-side. E.g. 1:30 vs 1:100 leverage on the same EUR/USD trade, and shows the margin delta, notional delta, and which scenario is safer. Portfolio aggregates up to 10 open positions and tells you the total margin tied up, the blended margin level, and which single position is the largest concentration risk. Both modes save to Strategy Profiles so you can reload them in two clicks.

AI Risk Analysis · Verdict: Healthy
$3,617 margin on a $10K account is 36% utilisation. Sustainable but tighter than the 30% desk threshold. A normal 50-pip EUR/USD pullback costs $500, leaving margin level above 700%.
1:30 is the ESMA cap for retail forex. Appropriate for this size. Going to 1:50+ frees margin but raises call risk.
A 3% adverse move (~325 pips) drops you to 221% margin level. Still safe. 5% move hits Danger zone.
6. AI Risk Analysis: verdict in plain English
CleaRank Financial AI reads your full margin setup. Instrument, leverage, size, balance, current volatility, and returns a verdict (Healthy / Tight / Over-Leveraged) with the reasoning written the way a desk head would talk over your shoulder. It flags whether your leverage fits the asset class, models how much drawdown the position survives before hitting Danger, and gives a pro tip pulled from how prop traders structure similar exposure. Particularly useful when the calculator says “margin: only $3,617” and your inner gambler whispers “go bigger”. The AI says, in writing, what the math says about that idea.
Margin caps by asset class: 1:30 forex, 1:50 US stocks, 1:100 crypto
ESMA-capped retail forex, 1:100 crypto perps, US stocks on Reg-T, or a prop-firm challenge that forbids margin calls outright. The margin math is the same idea but the leverage, asset class, and stress thresholds all differ. Pick the workflow that matches yours.
ESMA-capped retail
1:30 forex / 1:20 indices / 1:2 crypto. The EU/UK caps that decide how much margin every retail trade actually needs. The calculator applies them automatically.
High-leverage swing
Offshore brokers offering 1:200 or 1:500 free up margin, but a 1% move can vaporise the account. The Stress Test shows exactly when liquidation triggers.
Multi-position portfolio
Total margin across 3–10 open positions can quietly creep past 70% of equity. The Portfolio mode totals it for you and flags concentration risk.
Crypto perp trader
100× BTC perp looks cheap on margin until the liquidation price sits 1% away from entry. The Margin Call Distance metric makes that visible upfront.
Margin call vs stop-out: the math that decides which you hit first
Most margin calculators give you a single number. “you need $3,617”, and stop there. That number alone tells you nothing about whether the trade is safe to hold. This calculator runs the full set: it autofills the live price for any symbol from your broker’s typical feed (no copy-paste), handles cross-currency conversion when your account currency doesn’t match the quote (e.g. GBP/JPY on a USD account), applies the right leverage cap automatically (ESMA 1:30 for retail forex, 1:2 for retail crypto, 1:20 for indices, broker-specific for pros), and shows margin usage as a percentage of equity so you can see at a glance whether the position fits.
It’s the same margin engine that runs inside the CleaRank trading workbench used by paying customers. Exposed here for free with no signup required. CleaRank Pro adds Volatility Intelligence (live 14-day ATR, daily impact, margin call distance), the Margin Call Stress Test (-1% to -12% scenarios with auto-liquidation flagging), and Compare + Portfolio modes for multi-position aggregate margin. Ultra adds AI Risk Analysis that reviews each setup before you click buy and tells you, in plain English, whether the leverage fits the trade.
Cross-currency margin: when USD/JPY costs different than EUR/USD
Margin is the slice of your account balance your broker locks up as collateral to let you control a much larger position. If you buy 1 standard lot of EUR/USD at 1.0850. That’s €100,000 of exposure, about $108,500 notional, and your broker offers 1:30 leverage, the margin they require is $108,500 ÷ 30 = $3,617. The other $104,883 of exposure is leveraged. The trade behaves as if you’ve borrowed it: every pip the price moves is amplified against the $3,617 you have on the table, not against the $108,500 you “control” on paper. Get margin wrong and a 50-pip pullback that should cost $500 instead nukes the position because the broker auto-closes it at a 50% margin level.
“Margin isn’t your risk. It’s your broker’s risk. Your risk is what happens to the position before margin matters. Get both wrong and the broker decides when you exit, not you.”
The margin formula, in plain English
Two numbers do the work. Your notional value is your trade size × entry price, converted to your account currency. For 1 standard lot of EUR/USD at 1.0850 from a USD account that’s $108,500. Your leverage is whatever the broker offers for that asset class. 1:30 ESMA retail forex, 1:50 in the US (Reg T), 1:100–500 offshore, 1:2 retail crypto, 1:20 indices.
Margin is notional ÷ leverage, expressed in your account currency. Cross pairs (GBP/JPY from a USD account, EUR/CHF from a GBP account) need a triangular cross-rate conversion. The calculator handles it automatically. Stocks and commodities work the same way except notional = shares × price and leverage is fixed by the broker per asset class.
Same idea across forex, crypto, stocks. The calculator handles asset-class leverage caps + cross-currency math automatically.
Worked example: 1 lot EUR/USD on a $10K account
$10,000 USD account, ESMA-regulated retail broker, you want to buy 1 standard lot of EUR/USD at 1.0850. Here’s the margin calculation in four steps. The same four the calculator runs in milliseconds.
Net effect: your broker locks $3,617 of your $10,000. 36% utilisation. To hold 1 lot of EUR/USD. If the price moves 50 pips against you, the unrealised P&L is −$500 and your remaining free margin is $6,883. If it moves 200 pips against you, free margin drops to $4,383 and you’re at a 121% margin level, into watch territory. A 285-pip move triggers margin call. Plug those numbers into the calculator above and you’ll see the same answer in 50 milliseconds.
Margin required by leverage: quick reference
How leverage scales margin on the same trade. EUR/USD 1 standard lot at 1.0850 across the common broker tiers. The relationship is linear. Every 2× more leverage halves the margin, but the margin-call distance shrinks proportionally too, which is why offshore 1:500 looks cheap right up to the point a normal day’s range liquidates you.
Most regulated brokers cap retail forex at 1:30 (ESMA, FCA, ASIC). The US Reg-T standard is 1:50. Offshore brokers freely offer 1:200+. For crypto, ESMA caps retail at 1:2. Offshore perps reach 1:100. For prop-firm accounts, the firm’s daily loss + trailing drawdown rules matter more than the headline leverage; use our Prop Firm Auditor for that side.
Higher leverage = lower margin requirement, BUT shorter distance to margin call. The trade-off matters more than the headline number.
Five margin mistakes this calculator stops you making
Every trader has made these. The expensive ones make them every week and only spot the bleed when the broker auto-closes the position.
Confusing margin with risk
Margin is what your broker locks up to let you open. Risk is what you lose if the stop hits. They’re independent. A $3,617 margin trade can risk anywhere from $50 to $5,000 depending on stop placement.
Stacking margin without checking total
Three “small” 30% positions add up to 90%. One bad day from a margin call. The Portfolio mode aggregates margin across opens so you see the total exposure, not just per-trade.
Forgetting cross-currency conversion
GBP/JPY from a USD account needs a triangular conversion. The actual margin in USD often differs by 5–15% from the “obvious” answer. The calculator handles it automatically; eyeballing it doesn’t.
Chasing higher leverage for “more buying power”
1:500 doesn’t mean you can risk more. It means a 0.2% move closes the position. Higher leverage frees margin but compresses the distance to margin call. Almost always the wrong trade.
Ignoring the margin level after entry
Most retail brokers auto-close at 50% margin level. The Stress Test shows exactly what size of adverse move triggers it, and most traders are 30–50% closer to liquidation than they think on any given trade.

Frequently asked questions
What is a margin calculator?
A margin calculator works out the exact dollar amount your broker locks up as collateral to let you open a leveraged position. For 1 standard lot of EUR/USD at 1.0850 on a 1:30 ESMA broker, that’s $108,500 notional ÷ 30 = $3,616.67. The calculator above does this and also handles cross-currency conversion (e.g. GBP/JPY from a USD account), asset-class leverage caps (1:30 retail forex, 1:2 retail crypto, 1:50 US Reg-T), and crypto/stock notional math.
How do I calculate margin requirement for a forex trade?
Margin requirement = Notional value ÷ Leverage. Notional value = Lot size × 100,000 × Entry price, converted to your account currency. So 1 standard lot of EUR/USD at 1.0850 on a USD account at 1:30 leverage: 1 × 100,000 × 1.0850 = $108,500 notional; $108,500 ÷ 30 = $3,616.67 margin. For mini lots multiply by 0.1, micro lots 0.01. Cross-pair (GBP/JPY etc) needs a triangular FX conversion to your account currency. The calculator above does it automatically.
What is a margin call and how do I avoid one?
A margin call is your broker’s warning that your account equity has fallen below the maintenance margin level. Typically 100% or 50% of required margin, depending on the broker. If you don’t deposit more funds or close positions, the broker auto-liquidates at a stop-out level (most retail brokers liquidate at 50% margin level). To avoid one: never open positions where total margin usage exceeds 30% of equity, place hard stop-losses, and run the Stress Test before entering to see exactly what adverse move triggers liquidation.
What’s the difference between margin and free equity?
Margin is the dollar amount your broker locks up to hold your open positions. Call it “used margin”. Free equity (or free margin) is what’s left of your account balance to either absorb adverse moves or open new positions. Total equity = balance + unrealised P&L; free equity = total equity − used margin. If free equity hits zero, you’re at 100% margin level and at risk of a margin call. The calculator above shows used margin and the % of equity it represents on every trade.
How does leverage affect margin requirement?
Higher leverage lowers the margin requirement proportionally, but compresses the distance to a margin call by the same factor. The same 1-lot EUR/USD trade at 1.0850 needs $3,617 margin at 1:30, $1,085 at 1:100, and just $217 at 1:500. The catch: at 1:500, a 0.2% price move (about 22 pips) wipes out the margin and triggers the stop-out. Higher leverage is rarely “more buying power”. It’s tighter risk. Always compare the leverage to the typical daily range of the instrument before choosing it.
What leverage do brokers offer for retail vs professional accounts?
Retail leverage is regulated. In the EU/UK (ESMA/FCA) retail forex caps at 1:30, indices 1:20, commodities 1:10, crypto CFDs 1:2. In Australia (ASIC) similar caps apply. The US (NFA/CFTC) caps retail spot forex at 1:50 for majors. Professional / Elective Professional clients can request higher (1:100–500) with proof of trading experience + portfolio size. Offshore brokers offer 1:200–1000 unrestricted. Popular but uninsured by the regulators retail traders rely on. The calculator handles each tier automatically. Just select the leverage your broker actually offers.
How is margin calculated for crypto perpetual futures?
Crypto perp margin works the same way as forex but the units change: instead of lots × 100,000 × price, it’s coin units × price. So 0.1 BTC at $50,000 on a 1:5 perp = $5,000 notional ÷ 5 = $1,000 margin. The wrinkle is that crypto perps use isolated vs cross-margin modes, and most exchanges add a funding-rate fee every 8 hours that erodes margin if you hold across funding windows. The calculator handles the notional math; for funding-rate impact use the Breakeven Win Rate Calculator with the swap field.
