If you are asking how much to save for retirement, the honest answer is that it depends—but not as much as you might fear, and usually more than many people are saving. Your target is a function of your spending, guaranteed income, time horizon, taxes, and health-care costs. Rather than chase a single magic number, use a few evidence-based benchmarks, then calculate a personal target you can update each year.
Start With Your Replacement Rate, Not a Random Number
Most retirement plans aim to replace 70% to 80% of pre-retirement income, according to common financial-planning guidelines. Social Security replaces about 40% of income for an average worker, but the percentage falls for higher earners because benefits are progressive. A household earning $150,000 may need to replace a larger share from savings than one earning $60,000.
Ask two questions:
- What do you actually spend now, excluding retirement savings? Your current budget is a better starting point than a generic percentage.
- What will change in retirement? Commuting, work clothes, and mortgage payments may disappear; travel, health care, and hobbies may rise.
The Benchmark Rules of Thumb
Fidelity's widely cited guideline suggests saving 15% of pre-tax income each year, including any employer match, starting in your early 20s. It also publishes age-based savings multiples—assuming you retire at 67:
- 1x your salary by 30
- 2x by 35
- 3x by 40
- 4x by 45
- 6x by 50
- 7x by 55
- 8x by 60
- 10x by 67
These multiples are checkpoints, not guarantees. They assume steady salary growth, a diversified portfolio, and a retirement around 67. If you plan to retire at 55, travel extensively, or support family members, aim higher. If you have a traditional pension or plan to work part-time, your required savings may be lower.
Calculate Your Own Number in Four Steps
- Estimate annual spending. Use your current after-tax spending, then adjust for retirement changes. If you spend $80,000 now and expect $70,000 in retirement, start there.
- Subtract guaranteed income. Add Social Security, pensions, and annuities. If Social Security provides $30,000 and a pension provides $10,000, your portfolio must cover $30,000.
- Multiply the gap by 25. The classic 4% rule suggests a portfolio of 25 times your first-year withdrawal. A $30,000 gap implies a $750,000 portfolio. If the gap is $50,000, the target is $1.25 million.
- Adjust for taxes, health care, and longevity. Account for federal and state taxes on withdrawals and for Medicare premiums plus out-of-pocket costs. Fidelity estimates that a 65-year-old couple retiring in 2024 may need $165,000 after tax for health-care expenses. Add a buffer for long-term care, which can cost $100,000 or more per year for a private room.
Where to Save and How Much to Contribute
Use tax-advantaged accounts first, especially if your employer matches contributions.
- 401(k), 403(b), and most 457 plans: The employee contribution limit is $23,500 in 2025, with a $7,500 catch-up for those 50 and older.
- Traditional and Roth IRAs: The limit is $7,000 in 2025, plus a $1,000 catch-up at 50.
- HSAs: If you have a high-deductible health plan, an HSA offers a triple tax advantage and can supplement retirement health costs.
- Taxable brokerage accounts: Useful after tax-advantaged accounts are maxed.
If you cannot save 15% today, increase your contribution by 1 to 2 percentage points with each raise. Automate contributions so they happen before you can spend the money.
Why the 4% Rule Is a Starting Point, Not Gospel
The 4% rule comes from William Bengen's 1994 research and the Trinity study, which tested inflation-adjusted withdrawals over 30-year periods. It assumes a balanced portfolio and a 30-year retirement. Today, many planners suggest a range of 3.5% to 4.5%, depending on fees, asset allocation, and flexibility.
- Retiring early means a longer horizon and usually a lower withdrawal rate.
- High investment fees can reduce safe spending by 0.5% or more.
- A market decline early in retirement can increase sequence-of-returns risk.
- Dynamic spending—cutting back after bad markets—can raise the sustainable rate.
Common Mistakes and Smart Adjustments
- Underestimating health care and long-term care. Medicare does not cover most long-term care.
- Ignoring inflation. A 3% inflation rate can cut purchasing power by about 25% over 10 years.
- Claiming Social Security too early. Waiting from 62 to 70 can increase benefits substantially, though it is not right for everyone.
- Forgetting taxes. Traditional 401(k) and IRA withdrawals are taxed as ordinary income.
- Not revisiting the plan. Recalculate every year or after a major life event.
Bottom Line
How much to save for retirement is not one number for everyone. A reasonable target is 15% of income including an employer match, with age-based checkpoints such as 3x salary by 40 and 10x by 67. For a personalized figure, estimate retirement spending, subtract Social Security and pensions, multiply the gap by 25, and add buffers for taxes and health care. Save consistently, invest with low costs, and review your plan annually. Small, automatic increases now can close a large gap later.
