“How much do I actually need to retire?” is the question I hear more than any other, and the honest answer frustrates people: it depends. But that does not mean you are flying blind. There are solid benchmarks you can use to find a number that fits your life, and 2026 is a good year to run them — before another year of inflation reshapes the math.
Start With the Benchmarks
The most cited guideline comes from Fidelity, which suggests saving roughly 10 times your final salary by age 67. According to Fidelity’s research, hitting that target should replace a meaningful share of your pre-retirement income when combined with Social Security. The milestones along the way give you checkpoints to measure against:
- 1x your salary saved by age 30
- 3x by 40
- 6x by 50
- 8x by 60
- 10x by age 67
To get there, Fidelity recommends saving about 15% of your income each year, including any employer match. If you are behind those markers, do not panic — they are guideposts, not verdicts, and there are concrete ways to catch up that we will get to below.
The Multiply-by-25 Method
Benchmarks tied to salary are handy, but the most personalized approach starts with your spending, not your paycheck. Here is the cleanest way to estimate your number:
- Figure out your expected annual expenses in retirement.
- Subtract your guaranteed annual income, such as Social Security and any pension.
- Multiply the remaining gap by 25.
That multiplier reflects a conservative 4% withdrawal rate. If you expect to spend $60,000 a year and Social Security covers $30,000, you need to fund a $30,000 gap — which means a nest egg of roughly $750,000. This method is powerful because it ties your target directly to the life you actually plan to live rather than a generic salary multiple.
Why Your Number Is Personal
Benchmarks are averages, and you are not average. Several factors swing the target dramatically:
- Lifestyle: Someone who plans to travel constantly needs far more than someone happy gardening at home.
- Claiming age: Delaying Social Security raises your guaranteed income and shrinks the gap you must self-fund.
- Housing: Entering retirement with a paid-off home versus a mortgage or rent changes everything.
- Health and longevity: A longer life or higher medical costs require a bigger cushion.
This is also why a single scary headline number — “you need $2 million to retire” — is mostly useless. Your number could be much higher or much lower depending on these levers.
Don’t Forget Healthcare and Taxes
Two costs routinely blow up otherwise careful estimates. Healthcare is the first: a 65-year-old can expect to spend well over $150,000 on medical expenses across retirement, and that figure excludes most long-term care. Taxes are the second. Money in a traditional 401(k) or IRA is taxed on withdrawal, so $1 million in a pre-tax account is not $1 million of spending power. Building both into your estimate keeps you from a nasty surprise later.
The Power of Starting Now
“Someone’s sitting in the shade today because someone planted a tree a long time ago.”
Warren Buffett’s line, collected among his best-known sayings by Nasdaq, is really about compounding. The earlier you plant, the bigger the shade. A dollar invested in your thirties has decades to grow, while a dollar invested in your sixties has only a few years. That is why starting imperfectly now beats waiting for the perfect plan later.
The Mistakes That Throw Off Your Estimate
Even careful people miscalculate their retirement number, almost always in the same predictable ways. The most common is underestimating how long retirement will last. With many 65-year-olds living into their late 80s and beyond, planning for a 20-year retirement when you may need 30 leaves a dangerous gap. It is safer to plan for a long life and be pleasantly wrong than to run out of money at 85. Another frequent error is forgetting that spending is not flat across retirement — many retirees spend more in their active early years, less in the middle, then more again late in life as healthcare costs rise. People also routinely forget to account for inflation eroding their purchasing power over decades.
Stress-Test Your Number Before You Rely on It
Once you have an estimate, pressure-test it against the scenarios most likely to derail it. Ask yourself how the plan holds up if any of these happen:
- You live to 95 instead of 85.
- Inflation runs hotter than expected for several years.
- A market downturn hits in your first few years of retirement.
- You face a major medical event or need long-term care.
- You retire earlier than planned due to health or a layoff.
If your number survives those stresses with room to spare, you can retire with real confidence. If it cracks under one or two of them, you have found exactly what to shore up while you still have time.
Closing the Gap Before You Retire
If the math looks intimidating, you have more levers than you think:
- Max out tax-advantaged accounts and capture every dollar of employer match — that match is an instant 50% or 100% return.
- Use catch-up contributions if you are 50 or older to stash thousands more each year.
- Delay retirement by even two or three years to boost savings, shorten the drawdown period, and increase Social Security.
- Trim fixed costs now so your target number shrinks along with your spending.
Track Your Progress, Not Just Your Target
Setting a number is only the start; checking your progress against it keeps you on course. Review your retirement accounts at least once a year and compare your balance to the milestones for your age. If you are ahead, you may have the freedom to retire earlier or spend a little more along the way. If you are behind, an annual review catches the shortfall while you still have years to close it through higher contributions or a slightly later retirement date. The people who reach retirement comfortably are rarely the ones who guessed well — they are the ones who measured regularly and adjusted. Treat your retirement number as a living target you revisit each year, not a one-time calculation you file away and forget.
The Bottom Line
Do not let the lack of a single perfect number stop you from planning. Use the salary benchmarks as a guide, calculate your personal target from your real spending using the multiply-by-25 method, and adjust for healthcare and taxes. Then think in terms of a range rather than one precise figure, aim for the high end, and keep flexible levers you can pull. The goal is not to hit an arbitrary number to the dollar; it is to build a plan resilient enough to absorb whatever the next few decades throw at it.
