CFD Margin and Leverage Basics All Traders Should Know

Topic Summary

CFD margin and leverage are core concepts for trading Contracts for Difference (CFDs).

Margin is the amount of capital required to open a position, while leverage allows traders to control a larger position size than their account balance alone would allow.

These tools increase market exposure and can amplify both profits and losses.

Different asset classes, such as forex, shares, indices, commodities, and cryptocurrencies, have unique margin requirements based on volatility and regulation.

Traders must also consider initial and maintenance margin levels, effective versus maximum leverage, and the risk of margin calls.

Understanding how margin and leverage work is essential for managing risk, sizing positions effectively, and building a long-term trading strategy.

New traders can use demo accounts to practise these skills in a risk-free environment.

Key points:

• Margin is a deposit used to open and maintain CFD positions
• Leverage increases exposure beyond the account balance
• Margin requirements vary by asset class and regulatory region
• Mismanaging leverage can lead to margin calls or forced liquidations
• Tools like margin calculators help traders plan trade sizes accurately
• Practising on a demo account helps build confidence with margin and leverage

CFD margin is the money you need in your account to open a trade.

It acts as a deposit, giving you access to a much larger position than your balance alone would allow.

The leverage you choose determines how far that margin stretches.

A ratio like 30:1 means every $1 in margin gives you $30 in market exposure.

This can increase profits when trades move your way. It can also magnify losses when they don’t. Different assets have different rules.

Forex, shares, commodities, indices, and cryptocurrencies all carry unique margin requirements, shaped by volatility and regulation.

If you understand these mechanics, you can size your positions more effectively, reduce the risk of margin calls, and trade with greater control on platforms like PU Prime.

How Do Margin and Leverage Work? 

When you trade CFDs, margin is the money you set aside to open a position.

It is not a fee.

Think of it as a deposit that secures the trade while the rest of the position is borrowed from the broker.

There are two levels you need to know.

The first is initial margin, which gets you into the trade.

The second is the maintenance margin, which is the amount you must keep in your account to stop that trade from being closed.

If your balance drops under the maintenance level, you will face a margin call.

The numbers are easy to work out.

Take the size of your trade and divide it by the leverage offered.

That gives you the margin required.

Say you open a $100,000 position in EUR/USD with 30:1 leverage. Divide 100,000 by 30 and you get $3,333.

If the leverage were 20:1, you would need $5,000.

Leverage is expressed as a ratio, such as 10:1 or 100:1.

A ratio of 10:1 means every $1 in your account controls $10 in the market. At 100:1, that same $1 controls $100. This is what makes CFDs appealing.

It is also what makes them risky.

A small market move in your favor can look big in your account.

The same applies when it goes against you.

If your balance falls too far, the broker issues a margin call.

You may need to top up your account or close trades.

If you do not, the broker can close them for you.

That protects both sides from deeper losses.

To avoid this, keep a margin buffer and use leverage carefully.

Margin Requirements and Leverage by Asset Class

Margin rules are not uniform.

They shift depending on what you trade, how volatile that market is, and the regulations in place.

A trader in forex does not face the exact requirements as a trader in shares or cryptocurrencies, and the numbers make that clear.

• Forex. In forex, major currency pairs such as EUR/USD or USD/JPY usually carry a leverage cap of 30:1 for retail traders under ESMA rules. That works out to $3,333 margin for a $100,000 trade.
  
  Minor pairs tend to be limited to 20:1, meaning you would need $5,000 to open the same trade size. Professional clients can access higher ratios, but that comes with a higher bar for classification.
  
• Share CFDs. Share CFDs are tighter. For retail clients under ESMA and ASIC rules, all share CFDs are capped at 5:1.
  
  That means a $10,000 position requires $2,000 margin. Some offshore or unregulated brokers may offer higher ratios, such as 10:1 or 20:1, but those levels do not apply under major regulators.
  
• Commodities. Commodities are split into two groups. Gold is capped at 20:1, the same as major indices. That makes a $10,000 gold trade require $500 margin.
  
  Other commodities, including oil, are capped at 10:1, which means a $10,000 trade would need $1,000 margin.
  
• Indices. Indices land in the middle. Major benchmarks like the S&P 500 or the FTSE 100 are capped at 20:1, which means $500 margin for $10,000 exposure.
  
  Because indices are baskets of stocks, they tend to move less violently than single equities but more than forex majors.
  
• Cryptocurrencies. Cryptocurrencies are the strictest of all. The retail cap is 2:1. A $10,000 Bitcoin position would therefore need $5,000 margin.
  
  Daily price swings of five to ten percent are common, so regulators keep the leverage tight to limit retail risk.

The theme behind all of these numbers is simple. The more volatile or less liquid the asset, the more margin you need.

Market hours also play a role. Products that close overnight or trade in narrow sessions can gap, creating risk that is managed through higher requirements.

Typical Retail Leverage by Asset

Asset Class	Typical Retail Leverage	Margin Requirement	Example
Forex (majors)	30:1	3.33%	$100,000 ÷ 30 = $3,333
Forex (minors)	20:1	5%	$100,000 ÷ 20 = $5,000
Shares (majors)	5:1	20%	$10,000 ÷ 5 = $2,000
Shares (non-majors)	20:1	5%	$10,000 ÷ 20 = $500
Commodities (majors)	10:1	10%	$10,000 ÷ 10 = $1,000
Commodities (non-majors)	20:1	5%	$10,000 ÷ 20 = $500
Indices (majors)	20:1	5%	$10,000 ÷ 20 = $500
Cryptocurrencies	2:1	50%	$10,000 ÷ 2 = $5,000

How to Use a Margin Calculator

A margin calculator shows you how much money a trade will tie up before you hit buy or sell. It gives you the number upfront, so you are not guessing.

The steps are simple. Pick your account currency. Choose the product you want to trade. Enter the size of the position. Add the leverage available on your account. Press calculate. The tool then shows the margin required.

Say you want to trade one lot of EUR/USD with 30:1 leverage. The calculator will show $3,333 margin. Change the leverage to 20:1, and the margin moves to $5,000. You can adjust the inputs as often as you like to see how the numbers change.

PU Prime’s platform includes a margin calculator so you can run these checks before you trade. It’s a quick way to confirm that your account has enough free margin and to plan position sizes with more confidence.

What Are the Best Practices for Managing CFD Leverage?

Use Leverage as Market Access, Not a Gamble

Leverage allows you to access markets without needing the full trade value in your account.

That’s the benefit. Problems begin when traders see it as a way to chase quick wins.

The more you stretch your leverage, the harder it becomes to control risk.

Keep Position Sizes Small

Position sizing is one of the simplest but most powerful controls you have.

A common rule is to keep risk on each trade within one to two per cent of your account balance.

This way, even a series of losing trades won’t wipe you out.

It is a slower approach, but it keeps you in the game.

Set Stop-Loss Orders

Stop-loss orders allow you to define the maximum you are willing to lose before you even enter a trade.

They won’t protect you completely during market gaps or extreme volatility, yet they remain one of the most effective ways to keep losses manageable.

Many experienced traders consider them essential, not optional.

Understand Effective vs. Maximum Leverage

It is easy to focus only on the maximum leverage your broker offers, but what matters more is the effective leverage you actually use.

Effective leverage measures your real exposure against your account equity.

Keeping this number under control reduces stress on your margin and gives you more room to manage trades.

Match Leverage to Your Experience

If you are new to trading, high leverage can feel attractive, but it often magnifies mistakes.

Using lower ratios while you gain confidence is safer.

More experienced traders may scale up, though usually with strict rules in place for position sizing and risk management.

Maintain a Margin Buffer

Trading with little to no buffer above your required margin is risky.

Even a small move against your position can trigger a margin call.

By holding additional funds in your account, you reduce the chance of forced liquidations and keep more control over when to close a trade.

Diversify Your Exposure

Placing all of your margin into one asset leaves you vulnerable to sudden market shocks.

Diversification spreads that risk.

Holding positions across different asset classes or markets means one sharp move does not dictate the outcome of your entire account.

Stay Disciplined

Leverage creates opportunity, but it also tests discipline.

It can encourage overtrading or emotional decisions, especially after a string of wins or losses.

The ability to stick to your rules, avoid chasing losses, and treat each trade with the same level of care is what separates sustainable trading from gambling.

How Regulation Changes Leverage in CFD Trading

Leverage is not set by brokers alone. It is defined by the rules of the regulator in each region, and those rules can look very different depending on where you trade.

In Europe, the European Securities and Markets Authority (ESMA) introduced limits to reduce retail losses.

Major forex pairs are capped at 30:1. Non-major pairs, gold, and major indices sit at 20:1.

Other commodities are set at 10:1, while shares are capped at 5:1 and cryptocurrencies at just 2:1. ESMA also enforces automatic close-outs if your equity falls to half of the margin required.

On top of that, negative balance protection is mandatory, which means a losing trade cannot push your account below zero.

Australia follows a similar model. The Australian Securities and Investments Commission (ASIC) applied its rules in 2021, mirroring ESMA’s leverage caps for retail clients.

Traders who qualify as professionals can apply for higher ratios, but they also give up protections such as negative balance safeguards.

That difference between retail and professional status is one of the biggest divides in CFD regulation today.

Other regions take their own approach. The UK’s Financial Conduct Authority (FCA) keeps the ESMA framework in place.

In the United States, the Commodity Futures Trading Commission (CFTC) bans CFDs for retail clients altogether but allows forex with leverage capped at 50:1 for majors and 20:1 for minors.

Some Asian and Middle Eastern regulators allow higher ratios, though even there the trend is toward tighter oversight.

These changes reshaped the industry. Not long ago, retail clients in Europe could access 200:1 or even 400:1 leverage.

That era ended when regulators stepped in, aiming to give traders access to markets without exposing them to rapid wipe-outs.

Today, retail traders work within strict limits, while professionals can opt for higher risk with fewer safety nets.

The practical step for you is to confirm your broker’s license.

Every regulated broker lists its license number on its website, and you can cross-check it on the regulator’s register.

Platforms like PU Prime make these details public so clients know the rules that apply.

Trading under a regulated framework means leverage limits, margin close-outs, and client protections are in force, which reduces the chance of nasty surprises.

Common Mistakes to Avoid With Leverage and Margin

Leverage and margin are useful tools, but misusing them can lead to costly outcomes.

Avoiding these common mistakes can help you manage your risk more effectively.

Using too much leverage too early
Many beginners are drawn to high leverage for the potential returns, but this also increases the risk of large losses.

Starting with lower leverage gives you more room to learn and adjust.

Ignoring maintenance margin requirements
Opening a trade is only the first step.

Traders who focus only on the initial margin may be caught off guard by a margin call if their balance falls below the maintenance level.

Trading oversized positions
Large trades relative to your account size reduce your margin buffer and increase the chance of forced liquidation.

Keeping position sizes small helps protect your capital.

Not setting stop-loss orders
Without a stop-loss in place, losses can grow quickly during volatile market moves.

Stop-loss orders help define your risk before you even enter a trade.

Assuming all brokers offer the same terms
Margin requirements and leverage caps vary by broker and region.

Always check your broker’s regulatory framework and account type conditions before placing a trade.

CFD Margin FAQs 

What is the difference between margin and leverage?

Margin is the deposit you put aside to open a trade. Leverage is the multiplier that shows how much exposure you gain from that deposit.

How much leverage should I use as a beginner?

Start low. Using smaller ratios helps you see how leverage affects your trades without putting your account at major risk.

What happens if I get a margin call, and how can I avoid it?

A margin call means your account balance has fallen below the required level. The broker may ask you to add funds or close positions.

You can reduce the chance of this by maintaining a buffer of free margin and avoiding overleveraging.

Does higher leverage always mean higher risk?

Yes. Larger leverage increases both potential gains and potential losses. Even a small market move can have a big impact when leverage is high.

What is the difference between initial margin and maintenance margin?

Initial margin is what you need to open a trade.

Maintenance margin is the minimum balance you must keep to hold it. Drop below that level and you risk a margin call.

How do regulatory changes affect my trading?

Regulators set the maximum leverage you can use, margin close-out levels, and protections such as negative balance rules.

These limits vary by region and by client classification.

Can I lose more money than I deposit with CFDs?

If your broker provides negative balance protection, losses are capped at your account balance. Without it, you could lose more than your deposit.

What is negative balance protection, and do I have it?

Negative balance protection prevents your account from falling below zero. Many regulators require it for retail clients. You should check whether your broker provides this protection.

How do I calculate the margin required for a specific trade?

Use the formula: Margin = Trade size ÷ Leverage. For example, a $100,000 trade at 30:1 leverage requires $3,333 margin.

What trading platforms offer the best margin management tools?

Platforms like PU Prime provide calculators, account monitoring, and alerts so you can track your margin use in real time.
