Explanation: The calculator first computes the future value of your retirement savings, then applies the 4% rule to determine sustainable monthly withdrawals that should preserve your principal over a 30-year retirement period.

A: The 4% rule suggests that you can withdraw 4% of your retirement savings annually, adjusted for inflation, without running out of money for 30 years.
Q2: How accurate is this calculator?
A: This provides an estimate based on historical market returns. Actual results may vary due to market fluctuations and personal circumstances.
Q3: Should I adjust for inflation?

Q4: What if I have multiple income sources?

Q5: How often should I recalculate my retirement needs?
A: Review your retirement plan annually or whenever you experience significant life changes, market shifts, or changes in financial goals.
