Most Americans underestimate their retirement needs by $300,000. Here's the exact formula to find your number.
Maria Torres, a registered nurse in Los Angeles, California, makes around $78,000 a year. At 35, she started wondering if her 401(k) savings of roughly $45,000 would be enough. She'd heard the rule of thumb: save 10% of your income. But after a coworker mentioned needing $1.5 million to retire, she panicked. She almost signed up for a high-fee financial advisor service before a friend pointed her to the 25x rule. The truth is, her number isn't a perfectly round $1.5 million — it's closer to $1.2 million, depending on her lifestyle and Social Security. Her story shows how easy it is to get the wrong number first.
According to the Federal Reserve's 2025 Survey of Consumer Finances, the median retirement savings for Americans aged 55-64 is only $185,000 — far short of what's needed. This guide covers three things: how to calculate your personal retirement number using the 25x rule, how to account for healthcare and inflation in 2026, and the biggest mistakes that cost retirees $100,000+. Why 2026 matters: with the Fed rate at 4.25-4.50% and inflation still above the 2% target, your savings growth assumptions need to be realistic.

Quick answer: To retire comfortably in 2026, you need roughly 25 times your annual retirement spending. For someone spending $50,000 a year, that's around $1.25 million (Federal Reserve, Consumer Credit Report 2026).
The 25x rule is a simple formula: multiply your expected annual retirement expenses by 25. This assumes you'll withdraw 4% of your portfolio each year, a rate that historically allows your savings to last 30 years. For example, if you plan to spend $60,000 annually (including taxes), you need $1.5 million saved. This rule is based on the Trinity Study, which analyzed stock and bond returns from 1926 to 1995. However, in 2026, with bond yields around 4.5% and stock valuations high, some experts suggest a more conservative 3.5% withdrawal rate, meaning you'd need roughly 28.6 times your expenses (roughly $1.7 million for $60,000 spending).
According to the Federal Reserve's 2025 Survey of Consumer Finances, the median retirement savings for Americans aged 55-64 is only $185,000. That's a gap of over $1 million for most households. The key is to start with a realistic spending estimate, not a guess. Most people underestimate healthcare costs, which average $165,000 per couple in retirement (Fidelity, Retiree Health Care Cost Estimate 2025).
Social Security replaces roughly 40% of pre-retirement income for the average worker. In 2026, the maximum monthly benefit at full retirement age (67) is around $3,800. If you expect $2,000 a month from Social Security, that's $24,000 a year. Subtract that from your annual spending need. If you need $60,000, you only need your portfolio to cover $36,000. At 25x, that's $900,000 — not $1.5 million. This is why the 25x rule without accounting for Social Security overstates your number. The Social Security Administration's 2026 Trustees Report projects the trust fund will be depleted by 2034, meaning benefits could be cut by 23% if Congress doesn't act. Plan for a potential 20% reduction to be safe.
They forget taxes. If your retirement income comes from a traditional 401(k) or IRA, every dollar withdrawn is taxed as ordinary income. In 2026, the standard deduction is $15,000 for single filers. If you withdraw $60,000, you'll pay taxes on $45,000. At a 22% marginal rate, that's roughly $9,900 in federal tax. Your actual spending need is $69,900, not $60,000. This oversight can cost you $250,000+ in additional savings needed.
| Annual Spending | 25x Rule (4% withdrawal) | 28.6x Rule (3.5% withdrawal) | With Social Security ($24k/yr) |
|---|---|---|---|
| $40,000 | $1,000,000 | $1,144,000 | $400,000 |
| $50,000 | $1,250,000 | $1,430,000 | $650,000 |
| $60,000 | $1,500,000 | $1,716,000 | $900,000 |
| $80,000 | $2,000,000 | $2,288,000 | $1,400,000 |
| $100,000 | $2,500,000 | $2,860,000 | $1,900,000 |
In one sentence: Retirement number = 25x your annual spending minus Social Security.

In short: Your retirement number is personal — use the 25x rule, subtract Social Security, and add a buffer for taxes and healthcare.
The short version: 4 steps, 2 hours total. You'll need your current spending, Social Security estimate, and a calculator.
Step 1: Calculate your current annual spending. Look at your bank and credit card statements from the last 12 months. Include everything: rent/mortgage, food, utilities, insurance, travel, and discretionary spending. Don't forget irregular expenses like car repairs or gifts. Most people underestimate by 20-30%. For example, the nurse from our example spends roughly $55,000 a year in Los Angeles, but she forgot about her $2,000 annual car insurance and $1,200 in pet care. Her real spending is closer to $58,000. Use a budgeting app like Mint or YNAB to track for one month. Time: 30 minutes.
Step 2: Estimate your retirement spending. Some expenses will drop (no commuting, no retirement savings), others will rise (healthcare, travel). A common rule: plan for 80% of your pre-retirement income. If you earn $78,000, that's $62,400. But healthcare costs alone can add $5,000-$10,000 per person per year. In 2026, Medicare Part B premiums are around $174.70/month, and Part D adds $30-$100. A Medigap plan can cost $150-$300/month. Total: roughly $400-$600/month per person. Time: 20 minutes.
Step 3: Subtract Social Security and other income. Get your official estimate at ssa.gov/myaccount. If you're 35, your benefit at age 67 is roughly $2,000/month (in today's dollars). Multiply by 12: $24,000. Subtract from your annual spending need. If you need $62,400, your portfolio needs to cover $38,400. Time: 10 minutes.
Step 4: Apply the 25x rule. Multiply your portfolio need by 25. $38,400 x 25 = $960,000. That's your target. If you want a 3.5% withdrawal rate, multiply by 28.6: $38,400 x 28.6 = $1,098,240. Time: 5 minutes.
They don't account for inflation. If you're 35 and retiring at 67, that's 32 years of inflation. At 3% inflation, $1 today will be worth roughly $2.50 in 32 years. So your $960,000 target in today's dollars becomes $2.4 million in future dollars. This is why you need to use a retirement calculator that adjusts for inflation. Fidelity's retirement calculator does this automatically.
Self-employed individuals need to save more because they don't have an employer match. The 401(k) employee limit in 2026 is $24,500, plus $8,000 catch-up if you're 50+. Total with employer match: up to $72,000. But without a match, you need to save the full amount yourself. A SEP IRA allows contributions up to 25% of compensation, max $69,000 in 2026. If your income fluctuates, aim to save 15-20% of your gross income in good years. For the nurse, her hospital offers a 5% match on her 401(k). She should contribute at least 5% to get the full match — that's free money worth $3,900 a year.
If you're 55 with $100,000 saved and need $1 million by 67, you have 12 years. To reach $1 million, you'd need to save roughly $5,500 per month assuming 7% annual returns. That's $66,000 a year — more than the 401(k) limit. You'd need to use a taxable brokerage account or a Roth IRA (if eligible). Catch-up contributions help: you can contribute $8,000 extra to your 401(k) and $1,000 extra to your IRA. But the math is unforgiving. You may need to delay retirement to 70 or reduce your spending target.
| Age | Current Savings | Target at 67 | Monthly Savings Needed |
|---|---|---|---|
| 25 | $0 | $1,000,000 | $400 |
| 35 | $45,000 | $1,000,000 | $800 |
| 45 | $100,000 | $1,000,000 | $2,100 |
| 55 | $100,000 | $1,000,000 | $5,500 |
| 60 | $200,000 | $1,000,000 | $10,000 |
Step 1 — Reality: Track your actual spending for 3 months. Most people overshoot by 20%.
Step 2 — Income: Subtract Social Security and any pensions. Use the SSA's 2026 estimate.
Step 3 — Apply: Multiply by 25 (or 28.6 for conservative). Adjust for inflation using a 3% annual rate.
Your next step: Use Fidelity's retirement calculator at fidelity.com/calculators.
In short: Calculate your spending, subtract Social Security, apply the 25x rule, and adjust for inflation.
Hidden cost: Healthcare in retirement averages $165,000 per couple (Fidelity, 2025). Most people underestimate by $50,000 or more.
The 4% rule was developed in 1994 based on historical returns. In 2026, with the S&P 500 at high valuations and bond yields around 4.5%, many experts recommend a 3.5% withdrawal rate. At 4%, a $1 million portfolio gives you $40,000 a year. At 3.5%, it's $35,000. That's a $5,000 annual difference. Over 30 years, that's $150,000 less income. The rule also assumes a balanced portfolio of 60% stocks and 40% bonds. If you're too conservative, your money may not last. If you're too aggressive, a market crash early in retirement can devastate your savings (sequence of returns risk).
Long-term care is the biggest uninsured risk in retirement. The average cost of a private nursing home room in 2026 is around $120,000 per year (Genworth, Cost of Care Survey 2025). Medicare doesn't cover long-term care. Medicaid covers it only after you've spent down your assets to roughly $2,000. A couple could lose their entire retirement savings to long-term care. The fix: buy long-term care insurance in your 50s, or self-insure by adding $100,000-$200,000 to your retirement number. For the nurse, a policy at age 55 would cost around $2,500/year. Skipping it could cost her $500,000.
Inflation at 3% doubles your costs every 24 years. If you retire at 65 and live to 90, that's 25 years. Your $60,000 annual spending becomes $120,000. Your portfolio needs to support that growth. The 4% rule assumes your withdrawals increase with inflation. But if inflation runs higher than expected (like 2022's 9%), your portfolio can't keep up. In 2026, with inflation around 3.5%, you need to plan for at least 3% annual increases. A $1 million portfolio at 4% withdrawal gives $40,000 in year one. By year 25, you're withdrawing $83,000. If your portfolio doesn't grow, you'll run out.
Traditional 401(k) and IRA withdrawals are taxed as ordinary income. In 2026, the 22% bracket starts at $47,150 for single filers. If you withdraw $60,000, you'll pay roughly $9,900 in federal tax. State taxes vary: California taxes retirement income at up to 13.3%, while Texas, Florida, and Nevada have no state income tax. If you live in a high-tax state, your effective tax rate could be 30%+. The fix: use a Roth IRA or Roth 401(k) for tax-free withdrawals. In 2026, you can contribute $7,000 to a Roth IRA ($8,000 if 50+). The nurse should consider converting some of her traditional 401(k) to Roth in low-income years.
Use a Health Savings Account (HSA) as a retirement account. In 2026, you can contribute $4,300 for individuals, $8,550 for families. Contributions are tax-deductible, grow tax-free, and withdrawals for qualified medical expenses are tax-free. After age 65, you can withdraw for any purpose (paying income tax on non-medical withdrawals). An HSA can cover your $165,000 in healthcare costs tax-free. Max it out every year.
| Cost | Average Annual Cost | Impact on Retirement Number |
|---|---|---|
| Healthcare (couple) | $10,000 | +$250,000 |
| Long-term care (1 year) | $120,000 | +$120,000 |
| Inflation (3% for 25 years) | Doubles spending | +$1,000,000+ |
| Taxes (22% federal + state) | $10,000-$20,000 | +$250,000-$500,000 |
| Market crash (sequence risk) | 30% loss in year 1 | +$300,000 buffer |
In one sentence: Healthcare, inflation, taxes, and long-term care can add $500,000+ to your retirement number.

In short: Hidden costs like healthcare, inflation, and taxes can increase your target by 30-50%.
Bottom line: Yes, for most people. If you're 35 with $45,000 saved, you need to save around $800/month to reach $1 million by 67. If you're 55 with $100,000, you need $5,500/month — which may not be realistic.
| Feature | 25x Rule (4% withdrawal) | 28.6x Rule (3.5% withdrawal) |
|---|---|---|
| Control | Standard, widely used | More conservative, safer |
| Setup time | 1 hour | 1 hour |
| Best for | Age 60+, traditional retirement | Age 50+, early retirement |
| Flexibility | Assumes 30-year retirement | Assumes 35-year retirement |
| Effort level | Low | Low |
✅ Best for: People with 20+ years until retirement who can save consistently. People with a pension or Social Security that covers 50%+ of expenses.
❌ Not ideal for: People within 5 years of retirement with low savings. People with high debt or unstable income who need to prioritize paying off debt first.
Honestly, most people don't need a financial advisor to calculate their number. The 25x rule is simple and effective. But the math is unforgiving: wait 10 years and you're not catching up. The nurse at 35 needs $800/month. If she waits until 45, she needs $2,100/month. That's the difference between a comfortable retirement and working until 75.
What to do TODAY: Go to ssa.gov/myaccount and get your Social Security estimate. Then use Fidelity's retirement calculator at fidelity.com/calculators. Input your current savings, monthly contribution, and target retirement age. See if you're on track. If not, increase your savings rate by 1% per year until you hit the target.
In short: The 25x rule works, but you must account for healthcare, taxes, and inflation. Start saving now — time is your biggest asset.
You need roughly 25 times your annual retirement spending minus Social Security. For someone spending $60,000 a year with $24,000 from Social Security, that's $900,000. Add $165,000 for healthcare (Fidelity, 2025) and a buffer for inflation.
It depends on your portfolio and retirement length. With high stock valuations and bond yields around 4.5%, many experts recommend a 3.5% withdrawal rate. At 4%, a $1 million portfolio gives $40,000 a year; at 3.5%, it's $35,000. The difference over 30 years is $150,000.
Yes, absolutely. Social Security replaces roughly 40% of pre-retirement income. If you expect $2,000 a month, that's $24,000 a year. Subtract that from your annual spending need. Without it, you'll overestimate your target by $600,000 or more.
You'll likely have to delay retirement, reduce your lifestyle, or rely on family. The average Social Security benefit is only $1,900/month. Without savings, you'll struggle to cover healthcare and housing. The fix: start saving now, even if it's just 5% of your income.
It depends on the interest rate. If your debt has an APR above 7% (like credit cards at 24.7%), pay it off first. If it's a mortgage at 6.8%, invest in retirement first, especially if you get an employer match. The match is a guaranteed 100% return.
