Determining what percentage of salary should be saved for retirement is one of the most consequential financial decisions you will ever make. According to Fidelity Investments' 2024 retirement guidelines, a significant share of workers remain uncertain about whether their current savings rate will sustain them through retirement.
The problem is straightforward: save too little and you risk outliving your money; save too aggressively and you may sacrifice today's quality of life unnecessarily. This guide cuts through the conflicting advice to give you a clear, evidence-based framework for setting your personal savings rate.
You will learn what the major financial institutions recommend, how to adjust for your age and income, what to do if you start late, and how to check whether you are actually on track.
Why the Standard 15% Rule Exists
The most widely cited answer comes from Fidelity Investments, which recommends saving 15% of your pre-tax income for retirement each year, including any employer match.
Fidelity arrived at this figure by modeling a worker who starts saving at age 25, retires at 67, and aims to replace roughly 45% of pre-retirement income from personal savings, with Social Security covering the remainder.
The 15% benchmark assumes you invest in a diversified portfolio that earns an average annual return in line with historical equity and bond market performance. It also assumes you maintain that savings rate consistently for four decades.
The math works because of compound growth: a worker earning $60,000 who saves 15% annually and earns a 7% average return would accumulate a substantial nest egg by age 67, based on standard compound interest calculations available through any retirement calculator.
When considering what percentage of salary should be saved for retirement, the 15% rule serves as a reliable foundation because it balances current needs with future security.
However, the 15% figure is a starting point, not a universal law. Your personal number depends on when you start, how much you already have saved, and what kind of retirement lifestyle you want.
How to apply this: Run your current salary through a retirement calculator like Fidelity's Retirement Score and compare your projected savings against your current lifestyle expenses.
How Your Age Changes the Percentage You Need
Your age is the single biggest variable in determining what percentage of salary should be saved for retirement. The reason is simple: time in the market matters more than the amount you contribute in any single year.
A worker who starts saving at 25 can typically reach a secure retirement by saving 10% to 12% of salary. That same worker, if they wait until 35 to begin, may need to save 18% to 20%. Starting at 45 pushes the required rate to 30% or more, depending on income and expected Social Security benefits.
The Center for Retirement Research at Boston College publishes data showing that late starters face a steep climb. Their analysis indicates that delaying savings by just ten years can require nearly double the savings rate to reach the same retirement income target. This is not a linear relationship — the curve gets steeper the later you start.
A practical way to think about it: your target savings rate is roughly your age minus 15, expressed as a percentage. A 30-year-old aims for 15%, a 40-year-old for 25%, and so on. This rule of thumb, sometimes called the "age-based savings formula," provides a rough calibration that accounts for lost compounding time.
If you are wondering what percentage of salary should be saved for retirement at your specific age, this formula offers a starting point for the calculation.
How to apply this: Calculate your current age minus 15, then compare that number to your actual savings rate. If your actual rate is lower, increase your 401(k) contribution by 1% to 2% today and set a reminder to revisit in six months.
What Percentage of Salary Should Be Saved for Retirement When Income Varies
Income level changes the calculus significantly. What percentage of salary should be saved for retirement depends not only on how much you earn but on how much of that income you actually spend.
Higher earners generally need to save a larger percentage because Social Security replaces a smaller share of their pre-retirement income. A worker earning $40,000 per year may see Social Security replace roughly 40% of their income. A worker earning $150,000 might see Social Security replace only 20% or less, according to the Social Security Administration's benefit formula.
That means higher earners must cover a larger gap through personal savings.
Consider a two-income household earning $200,000 annually. If Social Security replaces only a small portion of that, the couple may need to save 20% or more to maintain their lifestyle. Meanwhile, a single earner making $45,000 with modest expenses might retire comfortably on a 10% savings rate plus Social Security.
The key metric is not your gross income but your replacement rate — the percentage of pre-retirement income you will need each year in retirement. Most planners estimate you need 70% to 80% of pre-retirement income, but frugal savers may need less, while those with expensive hobbies or travel plans may need more.
Asking what percentage of salary should be saved for retirement without accounting for income level and replacement rate produces misleading answers.
How to apply this: Use the Social Security Quick Calculator to estimate your future benefit, subtract that from your target retirement income, and divide the remainder by your current salary to find your personal required savings percentage.
The Employer Match Changes Everything
If your employer offers a 401(k) match, failing to capture the full match is equivalent to leaving part of your salary on the table. The match directly reduces the percentage you need to save from your own paycheck.
A typical match structure is 50% of your contribution up to 6% of salary, meaning if you contribute 6%, your employer adds 3%. That brings your total retirement savings to 9% of salary while you only contributed 6% from your own pay. The IRS sets annual limits on total 401(k) contributions, and the match counts toward those limits.
When calculating what percentage of salary should be saved for retirement, always include the employer match in your total. If your goal is 15% and your employer contributes 5%, your personal contribution only needs to be 10%. Many workers overlook this and either over-save unnecessarily or, more commonly, under-save because they never run the numbers.
Understanding what percentage of salary should be saved for retirement requires looking at both your contribution and your employer's contribution as one combined figure.
The IRS states that employer matching contributions are not taxable income to you in the year they are made, and they grow tax-deferred until withdrawal. This makes the match one of the highest-value forms of compensation available to any worker.
How to apply this: Log into your 401(k) portal today and verify you are contributing at least enough to capture the full employer match. If you are not, increase your contribution to the match threshold immediately.
Common Retirement Savings Benchmarks Compared
Different financial institutions and researchers publish varying recommendations. Here is a comparison of the most commonly cited benchmarks:
| Source | Recommended Savings Rate | Key Assumption | Action to Take |
|---|---|---|---|
| Fidelity Investments | 15% of pre-tax income | Start at 25, retire at 67 | Check your current rate against 15% |
| Center for Retirement Research | 10% to 15% | Varies by start age | Adjust upward if starting after 35 |
| Vanguard | 12% to 15% | Includes employer match | Include match in your calculation |
| T. Rowe Price | 15% to 20% | More conservative outlook | Aim for upper end if possible |
| AARP | 10% to 15% | Based on member surveys | Use as minimum, not target |
The variation exists because each organization models different market return assumptions, life expectancies, and spending patterns. The consensus range is 10% to 20%, with 15% as the midpoint that works for most people who start early and save consistently.
A common scenario involves a 30-year-old worker earning $70,000 who currently saves 8% including the employer match. Under Fidelity's model, this worker would fall short by roughly $300,000 at retirement. Increasing contributions by just 3% of salary — about $175 per month — could close most of that gap over 35 years.
This example illustrates why knowing what percentage of salary should be saved for retirement and then acting on that knowledge matters more than following any single institution's rule perfectly.
How to apply this: Pick the benchmark that matches your risk tolerance, then set up an automatic annual increase of 1% in your 401(k) contribution until you reach it.
Frequently Asked Questions About what percentage of salary should be saved for retirement
What if I have a pension?
If you have a defined-benefit pension, what percentage of salary should be saved for retirement changes substantially. A pension that replaces 30% of your income reduces your personal savings requirement by that same amount. Calculate your expected pension benefit, subtract it from your target retirement income, and base your savings percentage on the remaining gap.
Teachers, government workers, and union members often fall into this category and can save less aggressively, though it is wise to save something as a hedge against pension changes.
What percentage should a 50-year-old save if they have nothing saved?
A 50-year-old with no retirement savings needs to save 35% to 40% of salary to retire at a reasonable age, according to modeling from the Center for Retirement Research. This assumes aggressive investing and a willingness to work until 70.
The IRS allows catch-up contributions — an extra $7,500 annually in a 401(k) for those 50 and older, and an extra $1,000 in an IRA. This is a difficult savings rate to sustain, which is why starting early matters so much.
According to the Center for Retirement Research, someone starting from zero at age 50 may need to save 35% to 40% of salary. That daunting figure shows how much what percentage of salary should be saved for retirement rises when savings begin late.
Earning $15,000 to $20,000 annually in part-time work can trim your required savings rate by 3% to 5%. Even a modest income shift changes what percentage of salary should be saved for retirement, so factor it in early.
Does what percentage of salary should be saved for retirement change if I plan to work part-time in retirement?
Yes. If you plan to earn even $15,000 to $20,000 per year in part-time work during your first retirement years, you can reduce your required savings percentage by 3% to 5%. This strategy, sometimes called "phased retirement," extends the life of your portfolio because you withdraw less during the critical early years.
The trade-off is that part-time work may not be physically possible for everyone, so treat it as a contingency plan rather than a primary strategy.
Yes, what percentage of salary should be saved for retirement changes when you plan to work part-time in retirement.
Earning $15,000 to $20,000 annually from part-time work can reduce what percentage of salary should be saved for retirement by 3% to 5%.
Should I count my Roth IRA contributions toward my retirement savings percentage?
Yes, all retirement-specific savings count, including Roth IRA contributions, traditional IRA contributions, 401(k) deferrals, and employer matches. What percentage of salary should be saved for retirement is a total savings question, not a per-account question. If you contribute 10% to a 401(k) and 5% to a Roth IRA, your total rate is 15%.
The tax treatment differs by account, but the savings rate calculation treats them equally.
What if my salary fluctuates year to year?
For variable-income earners — freelancers, commission-based salespeople, and small business owners — a percentage-based rule is hard to apply. Instead, base your target on your average income over three years. In high-income years, save 20% to 25%; in lean years, save 10% to 12%. The goal is to hit an average of 15% across the full cycle.
Self-employed workers can use a SEP IRA or Solo 401(k), which allow contributions of up to 25% of net earnings, providing flexibility to save more in good years. If you are self-employed and asking what percentage of salary should be saved for retirement, the answer depends on averaging your variable income across multiple years.
Conclusion
Figuring out what percentage of salary should be saved for retirement does not have to be overwhelming. The evidence points to a clear, actionable framework:
- Start with the 15% benchmark established by Fidelity, including employer matches
- Adjust upward by 1% to 2% for every decade you delay starting to save
- Factor in your income level, since Social Security replaces less for higher earners
- Treat the employer match as non-negotiable free money and capture all of it
Your next step is simple: log into your retirement account today, check your current contribution rate, and increase it by 1% if you are below your target. One percentage point may not sound like much, but over 30 years it can mean tens of thousands of dollars in additional retirement income.
The best time to adjust your savings rate was yesterday. The second-best time is now.
