How Much to Save for Retirement — Targets by Age and Income
Retirement Savings Benchmarks by Age
These benchmarks assume you start saving around age 25, save 15% of gross income annually, invest in a diversified portfolio, and retire at 67. They’re guidelines, not exact targets — your situation may require more or less.
| Age | Savings Target (Multiple of Salary) | Example ($80K Salary) |
|---|---|---|
| 30 | 1x salary | $80,000 |
| 35 | 2x salary | $160,000 |
| 40 | 3x salary | $240,000 |
| 45 | 4x salary | $320,000 |
| 50 | 6x salary | $480,000 |
| 55 | 7x salary | $560,000 |
| 60 | 8x salary | $640,000 |
| 67 | 10-12x salary | $800,000 – $960,000 |
The 15% Rule
Saving 15% of your gross income (including any 401(k) employer match) is the most widely recommended target. This amount, invested consistently over a 40-year career, has historically produced enough to replace 70-80% of pre-retirement income through a combination of portfolio withdrawals and Social Security.
If 15% feels impossible right now, start with whatever you can — even 6% to capture your employer match — and increase by 1% each year. Going from 6% to 15% over nine years is far more achievable than jumping straight to 15%.
How Much Do You Actually Need?
The “magic number” depends on three variables: how much you plan to spend annually in retirement, how long your retirement will last, and what other income sources you’ll have (Social Security, pensions, rental income).
This formula is based on the 4% rule — the idea that you can withdraw 4% of your portfolio in year one and adjust for inflation each year with a high probability of not running out of money over 30 years.
| Desired Annual Spending | Social Security Income | Gap to Fill | Portfolio Needed (25x) |
|---|---|---|---|
| $50,000 | $24,000 | $26,000 | $650,000 |
| $70,000 | $28,000 | $42,000 | $1,050,000 |
| $100,000 | $32,000 | $68,000 | $1,700,000 |
| $150,000 | $36,000 | $114,000 | $2,850,000 |
The 4% Rule — What It Means
The 4% rule originated from the Trinity Study, which found that a retiree withdrawing 4% of their portfolio in year one (adjusting for inflation each subsequent year) had a very high probability of the portfolio lasting 30 years. With a $1 million portfolio, that means $40,000 in the first year.
The 4% rule assumes a balanced stock/bond portfolio and historical U.S. market returns. Some planners now suggest 3.5% is safer given lower expected future returns, while others argue 4.5% is fine for flexible retirees who can cut spending during downturns.

Income Replacement Ratio
Most financial planners target replacing 70-80% of your pre-retirement gross income. Why less than 100%? In retirement, you typically no longer pay payroll taxes (7.65%), aren’t saving for retirement (15%), may have lower housing costs (paid-off mortgage), and often have reduced commuting and work-related expenses.
However, some expenses increase: healthcare costs rise significantly after 65, and many retirees spend more on travel and hobbies in early retirement. Budget generously for healthcare and plan for higher spending in the first 10 years of retirement (“the go-go years”) before spending naturally declines.
Catch-Up Strategies If You’re Behind
| Strategy | How It Helps | Best For |
|---|---|---|
| Maximize Catch-Up Contributions | Extra $7,500/year in 401(k) after age 50; $1,000/year in IRA | Ages 50+ |
| Delay Retirement 2-3 Years | More saving years + fewer withdrawal years + higher Social Security | Everyone behind target |
| Delay Social Security to 70 | 8% annual increase per year delayed past full retirement age | Those with other income to bridge the gap |
| Reduce Current Spending | Every dollar saved is a dollar invested for the future | Those with room to cut |
| Generate Additional Income | Side income directed entirely to retirement savings | Those with marketable skills |
| Downsize Housing | Free up home equity for retirement savings or lower expenses | Homeowners with significant equity |
Key Takeaways
- Aim to save 15% of gross income starting in your 20s, targeting 10-12x your final salary by retirement age 67.
- Use the 25x rule: multiply the annual gap between spending and other income (Social Security, pensions) by 25 to find your target portfolio size.
- The 4% withdrawal rule provides a starting framework, but adjust based on your age, flexibility, and market conditions.
- Plan to replace 70-80% of pre-retirement income, with extra budgeted for healthcare costs after 65.
- If behind, the most impactful catch-up strategies are maximizing catch-up contributions and delaying retirement by 2-3 years.
Frequently Asked Questions
How much should I have saved for retirement by age 40?
A common benchmark is 3x your annual salary by age 40. On an $80,000 salary, that’s $240,000. This assumes you started saving around 25, contribute 15% of income, and earn average market returns. If you’re behind, increasing your savings rate and maximizing your 401(k) employer match are the fastest ways to catch up.
Is $1 million enough to retire?
It depends on your spending needs. Using the 4% rule, $1 million supports $40,000 in annual withdrawals. Combined with average Social Security benefits (~$24,000-$36,000/year), that provides $64,000-$76,000 in annual income. For many people, that’s sufficient. For higher spenders in expensive areas, it may not be enough.
What is the 4% rule for retirement?
The 4% rule says you can withdraw 4% of your portfolio in the first year of retirement, then adjust that dollar amount for inflation each year, with a high probability of the money lasting 30 years. A $1 million portfolio supports $40,000/year. It’s a starting guideline — see our withdrawal strategies guide for more sophisticated approaches.
How much should I save for retirement each month?
Target 15% of your gross income. On a $70,000 salary, that’s $875/month including any employer match. If that’s too much right now, start with enough to capture your full employer match (often 3-6% of salary) and increase by 1% each year until you reach 15%.
What if I start saving for retirement at 40?
You’ll need to save aggressively — roughly 25-30% of income to reach the same outcome as someone who started at 25 saving 15%. Maximize catch-up contributions after 50, consider delaying retirement by a few years, and delay Social Security to 70 for the maximum benefit. Starting late is much better than not starting at all.
