I invest in VOO and QQQM every month. I chose a 70/30 split: more VOO for broad U.S. exposure, some QQQM because I wanted a more aggressive side.
Then I looked at my projected retirement income. It covered only about half of my monthly goal.
That was not a surprise. I had to use money from a previous 401(k), so I already knew there was a hole. Still, seeing “about 50%” made the question harder to avoid: What can I do besides buy more VOO and QQQM?
People search how much money do I need to retire? My version is less abstract. I know my goal, and the retirement calculators say I’m not saving enough to reach it. What I do not yet have is a complete plan for the missing half.
Quick glossary
- Retirement income
- Money available to live on after leaving full-time work. It may come from Social Security, pensions, withdrawals, part-time work, or other sources.
- 401(k)
- A workplace retirement account with tax advantages.
- IRA
- An individual retirement account, separate from a workplace plan.
- Asset allocation
- How investments are divided among stocks, bonds, cash, and other assets.
- Social Security estimate
- A personalized projection based on the earnings recorded in your Social Security account. It is an estimate, not a guarantee.
First, I need to make sure the 50% means what I think it means
A calculator can produce a clean percentage from messy assumptions.
Is my monthly goal before tax or after tax? Does it include health insurance and out-of-pocket medical costs? Is inflation handled consistently? Did I include Social Security estimates for both spouses? Am I comparing today’s dollars with future dollars?
Until those inputs match, “50% funded” may be directionally useful without being precise.
This is my approximate planning result—not a promise of future income or a universal retirement target.
My first step is therefore not buying another share. It is writing one page with the same units on both sides:
- the monthly income I want in retirement;
- expected Social Security and any other reliable income;
- a cautious estimate of portfolio withdrawals;
- taxes, healthcare, and large irregular costs;
- the monthly gap and the annual gap.
More QQQM is not automatically the answer
When a goal is far away, it is tempting to think the missing half requires more risk. That would be a convenient answer. It may also be the wrong one.
VOO and QQQM are both stock funds, and many large technology companies appear in both. QQQM can make the portfolio more concentrated in growth-oriented companies; it does not create a separate retirement-income source.
Investor.gov explains that asset allocation should reflect both time horizon and risk tolerance. As retirement gets closer, the question changes from “How fast can this grow?” to “How much volatility can this plan survive when withdrawals begin?”
I am not planning to abandon VOO or QQQM. I am separating two decisions I had blended together: what I invest in, and how I close my retirement income gap.
The missing half has more than one lever
Six places to look—not six instant answers
Retirement Income Gap Check
Wondering whether you have enough to retire? This small check puts the monthly goal and expected income in the same units. It is a starting point, not a forecast.
Enter a monthly goal and the income sources you want to test.

Private by design: the values stay on this page and are not saved or sent. This check does not model taxes, inflation, healthcare, investment growth, or whether withdrawals are sustainable. Manual fallback: add the income sources, subtract them from the goal, and multiply a positive monthly gap by 12.
JavaScript is off. Add your monthly income sources, subtract the total from your goal, and multiply any positive gap by 12.
Contribute more—but check the account before the ticker
For 2026, the basic employee contribution limit for many 401(k), 403(b), and governmental 457 plans is $24,500. The general age-50-plus catch-up is $8,000, and plans may allow a higher catch-up for ages 60 through 63. IRA limits are separate. Eligibility, tax treatment, and plan rules matter.
The useful question is not simply “Can I buy more VOO?” It is “Do I have unused tax-advantaged space, an employer match, or a contribution increase I can sustain?”
Recheck the retirement date and Social Security timing
The Social Security Administration lets people review personalized estimates at different claiming ages. Delaying benefits can increase the monthly amount, but working longer or claiming later is not free: health, caregiving, employment, and life expectancy all matter.
I need to compare several dates, not build the plan around one optimistic date.
Test the income goal against real spending
“What’s your enough number?” sounds philosophical until it becomes a monthly bill.
I do not want to lower the goal just to make a calculator turn green. But I can separate needs, flexible spending, and occasional large expenses. I can also test whether the target resembles the life we actually live.
Consider income that does not come from selling investments
Part-time or consulting work could reduce early withdrawals. So could a pension, rental income, or another reliable source—if it truly exists and the costs are counted.
I should not enter imaginary income to make the plan work. But a realistic bridge for the first few retirement years may matter more than squeezing extra return from the same two ETFs.
Review diversification and withdrawal risk
A portfolio can look successful during accumulation and still be fragile when withdrawals begin. A bad market early in retirement can hurt more when money is coming out.
That is a reason to review asset allocation, cash needs, and withdrawal assumptions—not a reason to make a sudden trade after reading one article.
What I am doing next
- Download our current Social Security estimates.
- Rebuild the monthly goal in today’s dollars and state whether it is before or after tax.
- List every retirement account and its tax treatment, without treating all balances as interchangeable.
- Compare more than one retirement date and more than one spending level.
- Check contribution limits, employer match, and catch-up rules that actually apply to us.
- Review whether 70/30 VOO and QQQM still fits the time horizon and risk we can tolerate.
- Consider whether a fee-only fiduciary planner is worth paying for a second set of eyes.
The missing half is not one ETF ticker. It is a set of choices I have not yet turned into a plan.
If you have faced the same gap, what changed the picture most: saving more, working longer, adjusting the monthly goal, changing Social Security timing, or adding another source of retirement income?
