Retirement Planning 101: How Much Should You Save?

Save about 15% a year and hit key milestones so your nest egg, not Social Security alone, funds the lifestyle you want.

Written by

December 23, 2025

Most Americans will need their retirement savings to last 20-30 years, yet many don't know how much to save.

While 79% of Americans oppose Social Security benefit cuts, according to a Pew Research Center survey, the program's trust fund is projected to run short by 2033, and benefits replace only about 40% of pre-retirement income.

The question isn't whether you should save for retirement—it's how much you need to build the financial security for your golden years.

Key Insights

  • Financial experts recommend saving 15% of your gross income annually.
  • Aim to have 1x your salary saved by age 30, 3x by age 40, and 10x by age 67 to maintain your current lifestyle.
  • Social Security typically replaces only 40% of pre-retirement income, making personal savings essential for the other 60%.

Why Your Retirement Savings Matter More Than Ever

  • Increased life expectancy: Americans are living longer, with average life expectancy now reaching into the 80s. This means your retirement savings need to last potentially 20-30 years or more after you stop working.

  • Inflation impact: What costs $100 today will likely cost significantly more in 20-30 years. Historical inflation rates mean your purchasing power decreases over time, making it essential to save enough to maintain your standard of living.

  • Social Security limitations: Social Security benefits replace only about 40% of pre-retirement income for average earners. With the average retired worker receiving $1,999.97 per month in 2025 according to the Social Security Administration, and the program's trust fund projected to be depleted by 2033, personal savings are more critical than ever for maintaining your lifestyle.

  • Healthcare costs: Medical expenses typically increase with age, and Medicare doesn't cover all healthcare costs. Long-term care, prescription drugs, and supplemental insurance can create substantial expenses in retirement.

How Much Should You Save for Retirement?

The 15% Rule

Financial experts generally recommend saving at least 15% of your gross income for retirement. This includes both your contributions and any employer matching funds. If your employer matches 3% and you contribute 12%, you've hit the 15% target.

Age-Based Milestones

According to 2025 research from Empower, widely-used retirement benchmarks include:

Age Group

These benchmarks assume you want to maintain your current lifestyle in retirement and plan to retire around age 65-67. The encouraging news is that many Americans are meeting or exceeding these targets, particularly younger savers who are building strong early momentum with balances well above the recommended benchmarks.

Your Retirement Account Options

  • 401(k) plans: These employer-sponsored plans allow you to contribute pre-tax dollars, reducing your current taxable income. For 2025, you can contribute up to $23,500 annually, with an additional $7,500 catch-up contribution if you're 50 or older.

  • Traditional IRAs: Individual Retirement Accounts let you contribute up to $7,000 annually in 2025 ($8,000 if you're 50+). Contributions may be tax-deductible depending on your income and whether you have a workplace retirement plan.

  • Roth IRAs: These accounts use after-tax dollars, but qualified withdrawals in retirement are tax-free. The contribution limits are the same as traditional IRAs, but income limits apply for eligibility.

  • Employer matching: This is essentially free money. If your employer matches 3% of your salary when you contribute 3%, you're immediately earning a 100% return on that portion of your investment. Always contribute enough to get the full employer match.

The Power of Compound Interest in Retirement Savings

Compound interest is your most powerful ally in retirement planning. When your investments earn returns, those returns also start earning returns, creating exponential growth over time.

  • Starting early makes a difference: Someone who starts saving $200 monthly at age 25 and earns an average 7% annual return will have approximately $525,000 by age 65. Someone who starts the same $200 monthly contribution at age 35 will have only about $245,000 by age 65.

  • Time vs. amount: Starting early with smaller amounts often beats starting later with larger contributions. The extra 10 years of compound growth in the example above is worth more than $280,000—far more than the additional $24,000 in total contributions.

  • Dollar-cost averaging benefits: Regular monthly contributions help smooth out market volatility. You buy more shares when prices are low and fewer when prices are high, potentially improving your long-term returns.

Adjusting Your Retirement Savings Strategy

  • Lifestyle considerations: If you plan to travel extensively, move to a high-cost area, or maintain expensive hobbies in retirement, you may need to save more than the standard benchmarks suggest. Consider your retirement dreams when setting your savings targets.

  • Retirement timing: Planning to retire early requires more aggressive saving, while working past traditional retirement age gives you more time to save and less time needing to draw from your accounts.

  • Healthcare planning: Consider whether you'll have employer-sponsored healthcare in retirement or need to purchase individual coverage. Healthcare costs can significantly impact your retirement budget.

  • Debt considerations: Entering retirement debt-free makes your savings go further. Prioritize paying off high-interest debt while also contributing to retirement accounts, especially if you get an employer match.

Real-Life Retirement Savings Comparison

Let's compare two scenarios to illustrate the impact of starting early:

Starting at Age 25

Starting at Age 35

Monthly contribution

Value at age 65

~$906,000

~$680,000

Difference

$226,000 more

$226,000 less

Despite contributing $250 more per month and having a higher salary, the person who started at 35 ends up with over $200,000 less at retirement due to losing 10 years of compound growth.

Common Retirement Planning Pitfalls to Avoid

  • Over-relying on Social Security: The average Social Security benefit is approximately $2,000 per month—likely insufficient to maintain your current lifestyle, especially with the trust fund facing depletion by 2033.

  • Not increasing contributions with raises: Put at least half of any salary increase toward retirement savings to reach higher contribution rates painlessly.

  • Cashing out retirement accounts: Always roll over your 401(k) when changing jobs to avoid penalties and maintain tax-advantaged growth.

  • Ignoring fees: A 1% difference in annual fees can cost tens of thousands over your career.

  • Not diversifying investments: Spread retirement savings across different asset classes rather than concentrating in company stock or single investments.

Your Action Plan for Retirement Success

  • Start immediately: Even if you can only contribute $25 per month initially, starting creates the habit and begins the compound growth process. You can increase contributions as your income grows.

  • Maximize employer matching: This is the easiest way to boost your retirement savings. Contribute at least enough to get the full employer match before focusing on other financial goals.

  • Automate your contributions: Set up automatic transfers so retirement savings happen before you can spend the money elsewhere. Treat it like any other essential bill.

  • Review and adjust annually: Check your progress against the age-based benchmarks each year. If you're behind, consider increasing your contribution rate or adjusting your retirement timeline.

  • Take advantage of catch-up contributions: Once you reach age 50, you can contribute additional amounts to both 401(k)s and IRAs. Use these higher limits to accelerate your savings if you're behind your targets.

Bottom Line: How Much Should You Save for Retirement?

Retirement planning is about developing consistent saving habits, understanding your options, and making adjustments as your life and income change.

The most important step is starting, regardless of your age or current financial situation. Every dollar you save today becomes multiple dollars in retirement thanks to compound growth. Your future self will thank you for taking action now, and with each passing year, you'll feel more confident about your financial security in retirement.

Frequently Asked Questions

1. What should I do with my 401(k) if I change jobs?

Never cash it out, or you will face taxes and penalties. Instead, roll it over into an IRA or your new employer's plan. This keeps your money tax-advantaged and growing.

2. Should I pay off debt or save for retirement first?

Ideally, do both. Contribute enough to get your employer's full match (free money), then focus on high-interest debt (credit cards). Once that is gone, increase your retirement contributions.

3. What is the main difference between a Traditional and Roth IRA?

It comes down to when you pay taxes. With a Traditional IRA, you get a tax break now, but pay taxes when you withdraw. With a Roth IRA, you pay taxes now, but withdrawals in retirement are tax-free.
