Frequently Asked Questions
How much do I need to save for retirement?
A common guideline is 10-15% of your gross income. The 4% rule suggests you need 25× your desired annual retirement spending. For $60,000/year in retirement, you'd need about $1.5 million.
What is the 4% rule?
The 4% rule states you can withdraw 4% of your retirement portfolio in the first year, then adjust for inflation each year, with a very high probability (95%+) of not running out of money over a 30-year retirement. Based on the Trinity Study.
What is FIRE (Financial Independence, Retire Early)?
FIRE is a movement focused on extreme savings and investment (typically 50-70% of income) to achieve financial independence decades before traditional retirement age. FIRE number = Annual Expenses × 25.
