How Much Do You Need to Retire? The Real Number
The 4% rule gives you a starting point — but your real number depends on your spending, timeline, and risk tolerance.
The 4% Rule Starting Point
The 4% rule says you can withdraw 4% of your portfolio in year one of retirement, adjust for inflation each year, and your money should last 30+ years. This means you need 25x your annual expenses.
If you spend $50,000/year: target $1,250,000.
If you spend $80,000/year: target $2,000,000.
What the 4% Rule Does Not Account For
- •
- •Sequence of returns risk (retiring into a bear market is dangerous)
- •Very long retirements (40+ years if you retire early)
- •Social Security income (which reduces how much your portfolio must cover)
- •Unexpected medical costs
A More Conservative Approach
Many financial planners now suggest 3–3.5% withdrawal rates for early retirees. At 3%, you need 33x your expenses.
Income Sources Matter
Social Security reduces the burden on your portfolio significantly. A couple receiving $40,000/year in Social Security needs $40,000 less annually from investments.
How to Calculate Your Number
- 1.
- 2.Estimate annual retirement spending (today's dollars, adjusted for inflation)
- 3.Subtract guaranteed income (Social Security, pension)
- 4.Multiply the remainder by 25 (4% rule) or 33 (3% rule)
