Plan Sustainable Retirement Income
The safe withdrawal rate (SWR) determines how much you can withdraw from your portfolio each year without depleting your savings. Our calculator analyzes multiple withdrawal strategies—conservative, standard, and variable—to help you plan retirement income that lasts.
What is Safe Withdrawal Rate?
Safe Withdrawal Rate (SWR) is the percentage of your portfolio you can withdraw annually with high confidence your money will last throughout retirement. The famous '4% rule' from the Trinity Study found that 4% withdrawals historically sustained portfolios for 30+ years, though modern research suggests flexibility improves outcomes.

The 4% rule remains a useful guideline but isn't guaranteed. It's based on historical US market returns and 30-year retirements. For longer retirements, consider 3-3.5%. For shorter periods, 4.5-5% may be appropriate.
