Forex Leverage Calculator
Leverage, margin and position value are locked together by one simple relationship. Enter any two and this calculator instantly solves for the third — so you know exactly how much margin a trade ties up before you place it.
To calculate leverage, choose what you want to find (leverage, required margin, or position value) and enter the other two known values — the result is calculated instantly. For example, a $100,000 position on 1:100 leverage requires $1,000 of margin.

How to use Leverage Calculator
- 1Choose what to find: leverage, margin, or position value.
- 2Enter the two values you already know.
- 3See the result instantly, expressed as a 1:N leverage ratio.
- 4Adjust any input to compare how different leverage levels change the margin required.
How the leverage formula works
Leverage, margin and position value are connected by one equation: positionValue = margin × leverage. Rearrange it to solve for whatever you don't know: leverage = positionValue ÷ margin, or required margin = positionValue ÷ leverage.
A worked example: to open a $100,000 position (one standard lot of EUR/USD) at 1:100 leverage, you need $100,000 ÷ 100 = $1,000 of margin. At 1:30 that same trade needs $3,333; at 1:500 it needs only $200. The position — and therefore the profit and loss per pip — is identical in all three cases; only the margin locked up changes.
What leverage actually does to your risk
Leverage does not change how much you win or lose per pip — that is set by your position size, which you can check with the Position Size Calculator and the Pip Calculator. What leverage changes is how much of your own cash is tied up as margin, and therefore how much room your account has before a margin call.
Higher leverage means a smaller margin cushion. If a $1,000 margin position moves against you, a much smaller adverse move will trigger your broker's stop-out level than it would on a larger, lower-leverage margin. This is why traders 'blow accounts' with high leverage — not because leverage itself is dangerous, but because it tempts oversized positions relative to the account. Use the Margin Calculator to see the exact margin a specific pair and lot size requires.
Typical leverage limits by region
Regulated brokers cap retail leverage to protect traders. In the US (NFA/CFTC) retail forex is limited to about 1:50 on major pairs and 1:20 on minors. In the EU and UK (ESMA/FCA) the cap is 1:30 on majors, dropping to 1:20, 1:10 or 1:5 on more volatile instruments. Australia (ASIC) matches the 1:30 major-pair cap. Offshore and professional accounts may offer 1:100, 1:500 or higher.
Whatever your broker allows, the margin maths is the same everywhere — this calculator works for any ratio from 1:1 to 1:1000 so you can plan around your own broker's limit.
Frequently Asked Questions
What's a typical leverage ratio?
Retail forex leverage commonly ranges from 1:30 (EU/UK regulated brokers) and 1:50 (US) up to 1:500 or higher on some offshore brokers. Higher leverage means less margin is required to open the same position, but it leaves a smaller cushion before a margin call.
How much margin do I need for 1:100 leverage?
Required margin = position value ÷ leverage. On 1:100 leverage, a $100,000 position (one standard lot) requires $1,000 of margin; a $10,000 position requires $100. Lower the leverage and the margin requirement rises proportionally.
Does higher leverage increase my profit per pip?
No. Profit and loss per pip depend only on your position size (lot size), not your leverage. Leverage only changes how much margin the position ties up. Two traders holding the same one-lot position earn the same per pip whether they use 1:30 or 1:500 — the higher-leverage trader simply commits less margin.
What is a margin call and how does leverage affect it?
A margin call (and the broker's stop-out) happens when your account equity falls too close to the margin backing your open positions. Higher leverage ties up less margin per trade, which tempts larger positions and leaves a thinner buffer — so a smaller adverse move can trigger a stop-out. Sizing positions by risk, not by maximum leverage, is what keeps accounts alive.
