You'll often see a table circulating online that says you should have 1x your salary saved by 30, 3x by 40, 6x by 50, and 10x by retirement. Those numbers come from Fidelity's retirement savings guidelines, and while they're useful anchors, they're not commandments. A lot of people see them and immediately feel behind, or dismiss them entirely as unrealistic.

Neither reaction is particularly useful. What's more useful: understanding where those benchmarks come from, what they assume, and how to think about your own situation when the generic chart doesn't quite fit.

Why benchmarks exist and what they assume

Retirement savings benchmarks are built around one core question: how much do you need at retirement to fund roughly the same lifestyle you have now, without running out of money?

Fidelity's widely-cited guidelines assume you'll replace about 45% of your pre-retirement income from your own savings, with Social Security covering the remaining portion. They also assume you retire at 67, invest in a diversified portfolio, and withdraw at a rate that sustains you through a roughly 30-year retirement.

Change those assumptions and the benchmarks change too. If you plan to retire at 60, you need more. If you'll have a pension, you need less. If you expect to significantly downsize, you may need less. If you're going to work part-time in retirement, that helps too.

The benchmarks are directional tools, not precise targets for every person. Think of them as a speedometer that tells you whether you're moving fast enough toward a destination, while acknowledging that not everyone is going to the same destination.

The benchmarks by age

Here are the commonly cited savings multiples, based on annual salary:

By age 30: 1x salary. If you earn $60,000, the target is roughly $60,000 in retirement savings. Many people aren't close to this at 30, especially with student loans, early career salaries, or late starts investing. That's a real problem worth addressing, but it's not a reason to give up.

By age 35: 2x salary. At $60,000 annual income, roughly $120,000 in retirement accounts.

By age 40: 3x salary. About $180,000 at $60,000 income.

By age 45: 4x salary. Roughly $240,000.

By age 50: 6x salary. Roughly $360,000. This is the point where the compounding curve starts to steepen. Years of growth on a larger balance begin to do meaningful work.

By age 55: 7x salary. The gap between 50 and 55 reflects five more years of contributions and growth.

By age 60: 8x salary.

By age 67 (traditional retirement age): 10x salary. At $60,000 annual income, that's roughly $600,000 in retirement savings.

These numbers are specifically for 401(k)s and other retirement accounts combined, including IRAs, 403(b)s, and other tax-advantaged accounts. If you have a pension that will pay meaningful monthly income in retirement, your personal savings target can be lower.

How the math actually gets there

Going from 1x salary at 30 to 10x at 67 requires both consistent contributions and investment growth. Neither alone gets you there.

The IRS contribution limit for 401(k) plans in 2025 is $23,500 per year, with a catch-up contribution of an additional $7,500 for workers 50 and older. Most people don't contribute the maximum, and that's fine. The question is whether your contribution rate, combined with any employer match, is putting you on a path toward your target.

A rough rule of thumb: saving at least 15% of your gross income toward retirement (including any employer match) is often cited as a reasonable target for someone starting at a typical age. The right number for you depends on when you started, what you already have, and when you want to retire.

Employer matching is essentially free money. If your employer matches 50% of contributions up to 6% of your salary, contributing at least 6% captures the full match. Not contributing enough to capture the full match is one of the most common missed opportunities in personal finance.

What to do if you're significantly behind

Many people in their 40s and 50s find themselves well below these benchmarks. A late start or years of low contributions doesn't mean retirement is off the table. It means the math requires more aggressive action.

Options worth considering:

Increase your contribution rate. Even moving from 6% to 10% of income makes a meaningful difference over a decade or more. If you got a raise, route part of it to retirement before it becomes part of your spending baseline.

Use catch-up contributions. Once you're 50, the IRS allows higher annual contributions. For 2025, the catch-up is $7,500 on top of the standard $23,500 limit. Using this fully can add real money in the years before retirement.

Delay retirement by a few years. Working until 70 instead of 67 means three more years of contributions, three more years of growth, and three more years before you start drawing down savings. It also means a higher Social Security benefit if you delay claiming. Each year you delay Social Security past full retirement age increases your benefit by approximately 8%, according to the Social Security Administration.

Review your asset allocation. At any age, money sitting in a 401(k) that's too conservatively invested may not be growing enough to close the gap. This is a conversation worth having with a fee-only financial advisor. The right allocation depends on your situation.

Address other financial drags first. High-interest debt reduces your net worth and makes it harder to save. If you're carrying significant credit card debt or other high-rate debt, addressing that may need to happen alongside retirement savings, not after. See our framework for getting started with investing even when you're paying off debt.

The question of Roth vs. traditional

401(k) plans typically come in traditional (pre-tax contributions, taxes paid in retirement) and Roth (after-tax contributions, tax-free in retirement) versions. Which is better depends on whether you expect your tax rate to be higher now or in retirement. Nobody knows that with certainty.

A general principle: if you're early in your career and in a lower tax bracket now, Roth contributions are often advantageous. If you're in peak earning years and a higher bracket, traditional contributions reduce your current tax bill. Many financial planners suggest having both to give you flexibility in retirement. For a deeper comparison, see our article on Roth IRA vs. traditional IRA; the same logic applies to 401(k) accounts.

What Social Security adds to the picture

The benchmarks above don't assume you're living only on your 401(k). Social Security is meant to cover a portion of retirement income for most workers. The Social Security Administration provides an estimate of your projected benefit in your online "my Social Security" account. Knowing this number makes your personal savings target more specific.

Social Security's full retirement age is currently 67 for people born in 1960 or later. Claiming early at 62 permanently reduces your benefit. Delaying past full retirement age increases it, up to age 70. For most people, Social Security claiming strategy has a larger dollar impact than many investment decisions, so it's worth understanding before you're close to claiming.

Your next step

If you're ahead of these benchmarks, the main task is staying the course. Don't let lifestyle inflation eat your savings rate as income grows. If you're behind, the first step is understanding how far behind and running the numbers on what closing the gap actually requires, whether that's contribution rate changes, timeline adjustments, or both.

A fee-only financial advisor (one who doesn't earn commissions on products they recommend) can run retirement projections specific to your accounts, income, and timeline. If you're not ready to pay for advice, most 401(k) plan providers offer free projection tools that at least give you a realistic picture of where you're heading.
