How to Build a $1 Million 401(k)
A $1 million 401(k) is a milestone, not a universal retirement finish line. Its usefulness depends on spending, retirement age, taxes and other income.
Change the inputs and compare scenarios with the related RetirementMetric calculator.
Open the calculatorTranslate balance into cash flow
A simple 3% to 4% illustration on $1 million is $30,000 to $40,000 of first-year portfolio withdrawals before taxes. Use a range rather than treating any percentage as guaranteed.
Know what is taxable
Traditional 401(k) withdrawals are generally taxable, while qualified Roth withdrawals are treated differently. The account label therefore affects how much of the headline balance is spendable.
Keep saving after the milestone
Crossing $1 million does not eliminate sequence risk, inflation or longevity risk. Continue evaluating contributions and allocation against the actual retirement plan.
How to use this number responsibly
Use the result as a planning range rather than a forecast. Re-run the calculation when your balance, contribution rate, debt, retirement date, tax situation or spending target changes. For investment projections, compare multiple return assumptions because future market returns are unknown.
What this calculator does not know
RetirementMetric does not know your complete tax situation, benefits, investment holdings, insurance needs or household expenses. The tools are educational estimates, not individualized investment, tax or legal advice.
