If you’re 65 with $900,000 and no pension, the income your portfolio can provide depends on how much you withdraw and the number of years your savings need to last. Taking too large a withdrawal early in retirement could increase the risk of running short later, while spending too little may unnecessarily limit your lifestyle. Finding a sustainable monthly withdrawal rate can help balance current spending for a longer retirement.
Why a Big Savings Balance Won’t Guarantee a Long-Term Paycheck
Your retirement account statement shows how much you have saved, but not what you can spend each month. Without a pension, your retirement income likely comes from two sources: Social Security and withdrawals from your $900,000 portfolio. Those savings could be held in a traditional IRA, Roth account, taxable brokerage account or a combination of accounts, which can affect the taxes you owe on withdrawals.
Taking money from your portfolio also reduces the amount that remains invested. A withdrawal at 65 leaves fewer assets available to generate potential growth that could help fund expenses in your 70s, 80s and 90s. Your withdrawal rate is one of several factors that can affect whether $900,000 lasts long enough to support 30 years of retirement spending.
A financial advisor can help you evaluate tax considerations, investment strategy and account types when building a tax-efficient withdrawal plan.
How Monthly Withdrawals and Market Losses Impact Nest Eggs

Research from the Chicago-based financial services firm Morningstar estimates a 3.9% starting withdrawal rate for retirees seeking consistent, inflation-adjusted spending over a 30-year retirement. 1 That rate is based on forward-looking assumptions for stocks, bonds and inflation. Morningstar’s base case assumes a 90% probability of having money remaining at the end of 30 years, with portfolios holding roughly 30% to 50% in stocks. It is a planning benchmark based on those assumptions, not a guarantee.
Applying different withdrawal rates to a $900,000 portfolio shows how the 3.9% benchmark compares with lower and higher starting rates:
| Starting Withdrawal Rate | First-Year Total Income | First-Year Monthly Income |
|---|---|---|
| 3.5% | $900,000 × 3.5% = $31,500 | $31,500 ÷ 12 = $2,625 |
| 3.9% | $900,000 × 3.9% = $35,100 | $35,100 ÷ 12 = $2,925 |
| 5.0% | $900,000 × 5.0% = $45,000 | $45,000 ÷ 12 = $3,750 |
First-year withdrawals of 3.5% to 3.9% would provide approximately $2,625 to $2,925 per month before taxes, in addition to any Social Security benefits. The amount your portfolio can support over 30 years will depend on your investments, expenses, market returns and willingness to adjust spending.
A higher withdrawal rate can become more difficult to sustain when a market decline occurs early in retirement. Taking the same dollar amount after a loss means withdrawing a larger percentage of a smaller portfolio.
For example, assume the portfolio falls 20% before you take a $45,000 withdrawal:
- Starting portfolio: $900,000
- Balance after a 20% loss: $900,000 × 80% = $720,000
- $45,000 withdrawal as a share of the reduced portfolio: $45,000 ÷ $720,000 = 6.25%
- Balance after the withdrawal: $720,000 − $45,000 = $675,000
Although $45,000 was 5% of the original $900,000 balance, the rate goes up to 6.25% after the portfolio falls, leaving a $720,000 balance. Taking this withdrawal would leave only $675,000 invested for a potential market recovery.
The Levers That Could Help Stretch a Nest Egg to 30 Years
Delaying Social Security beyond full retirement age could increase your benefit by about 8% per year, until age 70. 2 For someone with a full retirement age of 67, waiting until 70 boosts the monthly benefit by roughly 24%, which can reduce how much you need to pull from your $900,000 portfolio each month.
| Claiming Age | Benefit Level | Example |
|---|---|---|
| 67 (full retirement age) | Starting amount | $2,071 (average 2026 monthly benefit) 3 |
| 68 | 8% higher | $2,237 |
| 69 | 16% higher | $2,402 |
| 70 | 24% higher | $2,568 |
Using the average 2026 monthly Social Security benefit of $2,071 as a starting point, a 24% increase would bring the monthly amount to about $2,568. That’s roughly $497 more per month, or about $5,964 more per year. Actual benefits will depend on your earnings record, full retirement age and claiming age.
Social Security is only one way to reduce pressure on your portfolio. Cutting discretionary spending, like travel or big purchases, can also help preserve savings after a down market year.awals leave more of your portfolio invested. You can increase spending again when markets recover.
A financial advisor can help you set a monthly withdrawal target based on your portfolio, Social Security income and expected retirement expenses.
