Key Assumptions & Notes

4% Rule: The safe withdrawal rate assumes you withdraw 4% of your total retirement savings annually. This strategy is designed to sustain your portfolio for approximately 30 years of retirement.

Social Security: Estimates are based on the 2024 average monthly benefit of approximately $1,907 at full retirement age (67). Benefits are reduced ~6.67% per year if claimed before 67, and increased ~8% per year if delayed up to age 70.

Inflation: Results are shown in today's dollars using a 2.5% annual inflation rate. The real rate of return used is 4.39%.
