"How much money do I need to retire?" is one of the most important financial questions you'll ever ask — and one of the most personal. The answer depends on your lifestyle, your expenses, your health, your other income sources, and how long you expect to live in retirement. But there are proven frameworks that can help you arrive at a realistic, achievable number.
💡 The quick answer: Multiply your expected annual retirement expenses by 25. That's your retirement target using the widely accepted 4% rule. Want $50,000/year? You need $1,250,000. Want $80,000/year? You need $2,000,000.
Step 1: Estimate Your Annual Retirement Expenses
The foundation of retirement planning is understanding how much money you'll actually spend each year in retirement. Most financial planners use the 70–80% rule as a starting point: you'll need about 70–80% of your pre-retirement income to maintain a similar lifestyle, since you'll no longer be commuting, saving for retirement, or paying payroll taxes.
However, this is a rough estimate. A more accurate approach is to build a detailed retirement budget. Consider:
- Housing — mortgage or rent, property taxes, insurance, maintenance
- Healthcare — this often increases significantly in retirement; Medicare premiums plus out-of-pocket costs average $6,000–$10,000+ per person annually
- Food and daily living
- Travel and leisure — many retirees spend more in early retirement when they're healthy and active
- Transportation
- Taxes — 401(k) withdrawals are taxed as ordinary income; plan accordingly
Once you have an annual expense estimate, that becomes your primary input for calculating your retirement number.
Step 2: Apply the 4% Rule
The 4% rule is the most widely used guideline in retirement planning. It states that if you withdraw 4% of your portfolio in your first year of retirement, then adjust that amount for inflation each subsequent year, your portfolio has a very high probability of lasting 30 years.
The rule was developed by financial advisor William Bengen in 1994, based on historical market data going back to 1926. He found that a 4% initial withdrawal rate from a diversified portfolio of stocks and bonds had never failed over any 30-year period in history.
| Annual Expenses | Retirement Target (25×) | Monthly Portfolio Income |
|---|---|---|
| $30,000/year | $750,000 | $2,500/month |
| $40,000/year | $1,000,000 | $3,333/month |
| $50,000/year | $1,250,000 | $4,167/month |
| $60,000/year | $1,500,000 | $5,000/month |
| $80,000/year | $2,000,000 | $6,667/month |
| $100,000/year | $2,500,000 | $8,333/month |
Remember: this is portfolio income only. Social Security, pensions, rental income, or part-time work would reduce how much you need from your portfolio.
Is the 4% Rule Still Valid?
Some financial researchers argue that given today's lower bond yields and higher valuations, a more conservative 3–3.5% withdrawal rate is safer, especially for early retirees who may need their money to last 40+ years. Others argue that the 4% rule remains valid for standard 30-year retirements when invested in a diversified portfolio.

Step 3: Account for Social Security and Other Income
Your retirement portfolio doesn't need to cover 100% of your expenses. Social Security, pensions, rental income, annuities, or part-time work all reduce the amount you need to withdraw from your portfolio.
The average Social Security benefit in 2026 is approximately $1,900/month ($22,800/year). For a married couple where both worked, combined benefits might be $3,500–$4,500/month. This significantly reduces the portfolio withdrawal needed.
💡 Example: You want $60,000/year in retirement. Social Security provides $24,000/year. You only need $36,000/year from your portfolio — requiring $900,000 (at 4% withdrawal), not $1,500,000.
Retirement Savings Benchmarks by Age
Fidelity Investments publishes widely cited benchmarks for how much you should have saved by each age, expressed as a multiple of your annual salary:
| Age | Savings Target | Example (at $60,000 salary) |
|---|---|---|
| 30 | 1× salary | $60,000 |
| 35 | 2× salary | $120,000 |
| 40 | 3× salary | $180,000 |
| 45 | 4× salary | $240,000 |
| 50 | 6× salary | $360,000 |
| 55 | 7× salary | $420,000 |
| 60 | 8× salary | $480,000 |
| 67 | 10× salary | $600,000 |
These benchmarks assume you want to maintain roughly your current lifestyle in retirement and will receive Social Security benefits. They're guidelines, not absolutes — your personal situation may require more or less.
What If You're Behind on Retirement Savings?
If you're behind on these benchmarks, don't panic — but do take action. Here are strategies that can make a significant difference:
Increase Your Savings Rate
Even a 2–3% increase in your savings rate can dramatically change your retirement outcome. If you're currently saving 6% of your income, increasing to 10% adds roughly 40% more to your annual retirement contributions. Small increases, sustained over decades, have enormous effects.
Take Advantage of Catch-Up Contributions
If you're 50 or older, the IRS allows extra "catch-up" contributions to retirement accounts. In 2026, you can contribute an extra $7,500 to your 401(k) (for a total of $30,500) and an extra $1,000 to an IRA (for a total of $8,000). These limits increase with inflation.
Delay Retirement
Working just 2–3 extra years can significantly improve your retirement security — you add more to your portfolio, reduce the number of years it needs to last, and increase your Social Security benefit (which grows approximately 8% per year for each year you delay claiming between age 62 and 70).
Reduce Planned Retirement Expenses
Downsizing your home, moving to a lower cost-of-living area, or planning a more modest retirement lifestyle reduces the portfolio size you need. Some retirees also choose to work part-time in early retirement — even $1,000–$2,000/month in part-time income dramatically reduces portfolio withdrawal pressure.
Healthcare: The Retirement Wild Card
Healthcare is consistently the most underestimated retirement expense. A 65-year-old couple retiring today can expect to spend approximately $315,000 on healthcare over their retirement, according to Fidelity's annual estimate. This doesn't include long-term care.
Medicare begins at age 65, but it doesn't cover everything — you'll pay premiums, deductibles, and out-of-pocket costs. Those who retire before 65 need to fund health insurance entirely on their own, which can cost $500–$1,500+/month depending on age and location.
Consider building a dedicated healthcare buffer into your retirement plan — an additional $200,000–$400,000 specifically earmarked for medical expenses.
The Impact of Inflation on Retirement
Inflation is retirement's long-term threat. At just 3% annual inflation, your purchasing power halves in approximately 24 years. A retiree at 65 who plans to live to 90 faces 25 years of inflation eroding their fixed income.
This is why most financial advisors recommend maintaining a significant allocation to stocks even in retirement. Stocks have historically provided the best inflation protection of any major asset class. A common recommendation is to keep your age in bonds and the rest in stocks — so a 65-year-old might hold 35–40% stocks and 60–65% bonds.

Final Thoughts
There's no single "right" retirement number — it depends entirely on the life you want to live and the income sources available to you. But the framework is universal: estimate your expenses, account for guaranteed income, apply the 4% rule, and start saving as early as possible in tax-advantaged accounts invested in low-cost index funds.
The most important thing is to start. Even if you're behind, every dollar saved today is worth more than a dollar saved tomorrow — thanks to compound interest. Run the numbers, make a plan, and take the first step.
