Formula
Effective leverage formula
Notional Value
Contracts × Contract Size × Price × Base→Account Rate
Effective Leverage
Notional Value ÷ Account Equity
Margin %
Account Equity ÷ Notional Value × 100
Worked Example
Given
2 S&P 500 CFD contracts · Contract size = 50 · Price = 5,000 · Account equity = $50,000
- Notional Value
- 2 × 50 × 5,000 = $500,000
- Effective Leverage
- $500,000 ÷ $50,000 = 10:1
- Margin %
- $50,000 ÷ $500,000 × 100 = 10%
Frequently Asked Questions
- What is effective leverage?
- Effective leverage is the ratio of your total position notional value to your account equity. It shows how many times your own capital is at work. A $250,000 position with $25,000 of equity = 10:1 effective leverage, meaning a 10% adverse move wipes out your full account.
- How does effective leverage differ from broker-offered leverage?
- Broker leverage is the maximum you are allowed to use (e.g. 20:1). Effective leverage is what you are actually using based on your current position size and equity. Experienced traders often deliberately use less leverage than the broker maximum — effective leverage is the number that matters for risk management.
- What is a safe effective leverage level?
- Professional guidelines suggest effective leverage of 2:1–5:1 for most traders. At 10:1, a 10% adverse move eliminates your account. At 20:1 (the EU retail maximum for indices), a 5% move does the same. Many institutional traders operate below 3:1 effective leverage even when higher leverage is available.
- What is margin percentage?
- Margin percentage is the inverse of effective leverage: it shows what fraction of your notional value is covered by your own equity. At 10:1 effective leverage, margin percentage = 10%. This is useful when comparing margin requirements across different brokers and instruments.
