What is a Safe Retirement Income?

A safe retirement income often follows the 4% rule: withdraw 4% of your retirement savings in year one and adjust for inflation annually. For a $1M portfolio, that equals about $40,000 per year. Success rates of 90–95% over 30 years depend on your asset mix, time horizon, and spending flexibility. Use this calculator to test scenarios and add Social Security.
