Trading leverage: definition, calculation and risks in 2026

What is leverage in trading?

Leverage (or financial leverage) is a mechanism offered by brokers that allows a trader to control a position whose value far exceeds their available capital. In simple terms, leverage multiplies a trader's investment capacity by "lending" them additional funds.

The principle is based on the concept of margin. When a trader opens a leveraged position, they only deposit a fraction of the total position value. This fraction is called the margin. The rest is provided by the broker.

For example, if a broker offers 1:100 leverage, the trader only needs to deposit 1% of the position value. With $1,000 in capital, they can open a position worth $100,000. If the market moves 1% in their favour, the gain is $1,000, representing a 100% return on capital. But if the market moves 1% against them, they lose $1,000, which is their entire capital.

Leverage is a double-edged sword. It does not create wealth. It simply amplifies market movements relative to the trader's capital. This is why risk management is absolutely essential when using leverage.

Leverage ratios explained

Here are the most common leverage ratios in forex and CFD trading, along with the required margin for each:

1:30 leverage. This is the maximum allowed in Europe for retail traders on major forex pairs. It offers a good balance between opportunity and protection but limits the possibilities for experienced traders with smaller accounts.

1:100 leverage. Popular with international brokers. It allows effective trading with modest capital. With $500, you control $50,000, creating meaningful movements even on small price fluctuations.

1:500 leverage. The highest among regulated brokers. Offered notably by RaiseFX (FSCA regulated, licence #50506, based in Johannesburg, South Africa). This leverage level is intended for experienced traders who master risk management. It provides maximum flexibility in position sizing.

How to calculate leverage and margin

Understanding leverage and margin calculations is fundamental for every trader. Here are the formulas and concrete examples.

The difference is significant. With 1:500 leverage, the margin required to open a standard lot is only $200, compared to $1,000 with 1:100 leverage. This leaves more free margin to absorb market fluctuations and reduces the risk of a margin call.

However, higher leverage does not mean you should use all available capacity. Experienced traders rarely use more than 5-10% of their maximum leverage. The advantage of high leverage is flexibility, not an incentive to over-expose your capital.

Advantages and risks of leverage

Advantages of leverage:

• Accessibility. Leverage allows trading with a reduced initial capital. A trader with $500 can access significant positions in the forex market.
• Potential returns. Gains are amplified proportionally to the leverage used. A 0.5% market move with 1:100 leverage generates a 50% return on capital.
• Flexibility. High leverage provides more free margin, allowing position diversification or absorption of temporary drawdowns.
• Capital efficiency. With less margin tied up per position, the trader can manage their overall capital more efficiently.

Risks of leverage:

• Amplified losses. Leverage amplifies losses exactly like gains. With 1:500 leverage, a 0.2% adverse movement is enough to lose the entire margin.
• Margin call. If losses reduce capital below the required margin level, the broker may automatically close the trader's positions.
• Over-exposure. The temptation to use all available leverage can lead to positions disproportionate to risk tolerance.
• Psychological stress. Oversized positions relative to capital create emotional pressure that impairs rational decision-making.

Leverage regulation by country

Leverage is regulated differently across jurisdictions. Here is a comparison of leverage limits for retail traders.

Europe, the UK, and Australia have applied strict restrictions since 2018-2021, with maximum leverage of 1:30 on major forex pairs. These restrictions aim to protect beginner traders from excessive losses.

South Africa, through the FSCA, allows higher leverage while maintaining a solid regulatory framework. This is why brokers like RaiseFX (FSCA licence #50506, based in Johannesburg) can offer 1:500 leverage in a regulated and secure environment, unlike offshore brokers that offer high leverage without any regulatory protection.

For professional traders in Europe (MiFID "professional client" status), leverage restrictions are lifted. However, obtaining this status requires meeting at least two of three criteria: professional experience in the financial sector, an investment portfolio exceeding EUR 500,000, or significant trading volume over the past 12 months.
