The 4% Rule Explained

The Safe Withdrawal Rate (commonly 4%) originates from the Trinity Study. It suggests that if you withdraw 4% of your invested portfolio in your first year of retirement and adjust for inflation thereafter, your money has a high statistical probability of lasting 30+ years without running out.

The Power of Your Savings Rate

While compound interest does the heavy lifting in the long run, your savings rate is the primary driver of how quickly you reach Financial Independence. Increasing your monthly investments directly accelerates your FIRE timeline, shaving years off your mandatory working life.
