FAQ
How much do I need to retire?
General rule: 25x your desired annual income (4% withdrawal rule). Need $60,000/year? Save $1.5 million. Don't forget Social Security (~$25k/year average) and pensions may supplement your savings.
What is the 4% rule?
Withdraw 4% of your portfolio in year 1 of retirement, adjust for inflation each year. Historical data shows this lasts 30+ years with 95% success rate. Conservative investors use 3.5%, aggressive 5%.
How much should I save per month for retirement?
General guideline: 15% of gross income including employer match. Start with at least enough to get full employer match, increase 1% per year. Earlier you start, less you need to save (compound interest!).
