About Safe Withdrawal Rates

The 4% rule, from the Trinity Study, suggests you can withdraw 4% of your retirement portfolio in the first year, then adjust that amount for inflation each subsequent year, with a high probability (95%) that your money will last 30 years.

Key Factors Affecting Safe Withdrawal Rates:

Portfolio Allocation: More stocks generally allow higher withdrawals but with more volatility
Retirement Duration: Longer retirements require more conservative withdrawal rates
Market Conditions: Sequence of returns risk is critical in early retirement years
Inflation: Higher inflation requires more conservative withdrawal rates
Spending Flexibility: Ability to reduce spending in down markets improves success rates

Monte Carlo Simulation: This calculator runs 1,000 random market scenarios based on historical returns to estimate the probability your portfolio will last through retirement.
