What Is the 4% Retirement Rule?
The 4% rule is a widely-used financial guideline that helps you determine how much money you need to retire comfortably. It suggests that you can withdraw 4% of your total retirement savings each year without running out of money over a 30-year retirement period.
For example:
- If your annual expenses are $50,000, according to the 4% rule, you would need:
RequiredRetirementSavings=0.04AnnualExpenses=0.0450,000=1,250,000
This means you’d need $1.25 million in retirement savings to safely withdraw $50,000 per year.
