How Much Will My 401(k) Pay Me Per Month?

Quick Answer

Many retirees use the 4% rule, which suggests withdrawing 4% of your retirement savings annually.

These figures are estimates and do not include taxes or Social Security benefits.

How To Estimate Monthly Income From Your 401(k)

Use this simple formula:

Monthly Income = (401(k) Balance × Withdrawal Rate) ÷ 12

For example, with a $500,000 balance and a 4% withdrawal rate: $500,000 × 4% = $20,000 annually, or $1,667 per month.

Factors That Affect Your Monthly Income

Retirement Age

Retiring earlier generally means your money must last longer. Someone retiring at 62 may need a lower withdrawal rate than someone retiring at 70.

Investment Returns

If your investments continue growing during retirement, you may be able to safely withdraw more over time.

Withdrawal Strategy

Common approaches include the 4% rule, fixed monthly withdrawals, Required Minimum Distributions (RMDs), and annuities.

Taxes

Traditional 401(k) withdrawals are typically taxed as ordinary income. Your actual take-home income may be lower than your estimated withdrawal amount.

Example Retirement Income Scenarios

Example 1: $300,000 401(k)

Using the 4% rule: $12,000 annually, or $1,000 per month. See our guide on how much you need for $1,000/month.

Example 2: $600,000 401(k)

Using the 4% rule: $24,000 annually, or $2,000 per month.

Example 3: $1 Million 401(k)

Using the 4% rule: $40,000 annually, or $3,333 per month.

Is the 4% Rule Still Relevant?

The 4% rule remains one of the most widely used retirement planning guidelines. However, some financial planners recommend withdrawal rates between 3% and 5% depending on market conditions, retirement length, risk tolerance, and other income sources.

Don't Forget Social Security

Many retirees combine 401(k) withdrawals with Social Security. For example, $1,667/month from your 401(k) plus $2,000/month from Social Security equals $3,667/month total retirement income.

Building a larger balance starts with capturing your full employer 401(k) match and maximizing contributions while you're working.
