What is the 4% rule? Retirement withdrawals explained
The 4% rule is a practical strategy for working out how much you can withdraw from your investment portfolio each year without running out of money over the course of your retirement. Imagine your portfolio is an apple: the rule tells you the slice you can eat each year without using it all up.
Origin and basic concept of the 4% rule
The 4% rule comes from historical market studies that analysed diversified portfolios of shares and bonds. According to this analysis, if you withdraw 4% of your initial capital in the first year and adjust that amount for inflation each year, there is a high probability that your portfolio will last at least 30 years.
- Simple example:
- Initial capital: €300,000
- Year 1 withdrawal: 4% of €300,000 = €12,000
- Inflation adjustment: if inflation was 2%, in year 2 you would withdraw €12,240.
Why 4% and not another percentage?
Historical basis
Studies such as the “Trinity Study” in the United States showed that an initial 4%, with a 60/40 portfolio (shares/bonds), held up in most 30-year scenarios since 1926.
- Everyday analogy:
Think of your portfolio as an orange tree: you pick only the ripe oranges (4%) and let the rest keep growing so there is a fresh harvest every year.
The risks of withdrawing more
- Withdrawing 5% or 6% can deplete your capital sooner than expected if markets fall.
- Withdrawing less (3%) offers more safety, but can be excessively conservative and reduce your quality of life.
How to adapt the 4% rule to your situation
- Review your life expectancy and retirement horizon.
If you are planning a longer retirement, 3.5% may be more suitable. - Diversify your portfolio.
A mix of global equities and government bonds. - Allow for unexpected expenses.
Keep an emergency fund on top of the 4%. - Review regularly.
If markets fall 20%, you may need to adjust your withdrawals.

Step-by-step practical example
Imagine you have €500,000 in your portfolio:
- Year 1: you withdraw 4% → €20,000
- 2% inflation: in year 2 you withdraw €20,400
- Market adjustment: if your portfolio drops to €490,000, you keep using the initial base for the calculation (€500,000 × 4%), not the new value, to stay on strategy.
