How Much Money Do You Need to Retire Comfortably?

A 58-year-old woman emailed a financial advisor last year with a question that haunts millions of people: “I have $340,000 saved. Can I retire at 65?” The honest answer was complicated — and that’s exactly the problem with retirement planning. Everyone wants a single number, but the right number depends on a dozen different variables that are unique to your life.

The quick rule of thumb most advisors use is 25 times your annual expenses. Spend $50,000 a year? You need $1.25 million. Spend $80,000? You need $2 million. But honestly, that rule tells you almost nothing without knowing your Social Security benefits, whether you’ll have a mortgage, your health situation, and where you plan to live. Save too little and you run out of money at 82. Save too much and you spent your healthiest years grinding at a desk when you could’ve been living.

I’m going to break down the real numbers — what people actually spend in retirement, what Social Security covers, and how to figure out your personal target. When you’re ready to see where you stand, our Retirement Calculator gives you a personalized projection based on your actual situation.

The 4% Rule: Still the Best Starting Point

William Bengen, a financial advisor, published a study in 1994 that changed retirement planning forever. He analyzed every 30-year period in U.S. market history going back to 1926 and found that retirees could withdraw 4% of their portfolio in year one, adjust for inflation each year after that, and not run out of money in 96% of scenarios. The Trinity Study later confirmed it.

Here’s what 4% looks like in real dollars:

$40,000/year spending: Need $1,000,000 saved
$50,000/year spending: Need $1,250,000
$60,000/year spending: Need $1,500,000
$80,000/year spending: Need $2,000,000
$100,000/year spending: Need $2,500,000

The 4% rule assumes a 50-60% stocks / 40-50% bonds portfolio. It survived the Great Depression, the 2008 crash, the dot-com bubble, and the 2020 COVID meltdown. In most historical periods, the portfolio didn’t just survive — it actually grew, meaning retirees ended up wealthier than when they started.

Two important caveats though. First: the rule was designed for 30-year retirements. If you’re planning to retire at 45 and live to 95, that’s 50 years, and you’d be safer at a 3.0% to 3.5% withdrawal rate. Second: the brutal inflation of 2022-2024 (peaking at 8%) reminded everyone that this rule isn’t bulletproof. It works, but it’s a starting point, not a guarantee.

What Retirees Actually Spend (Real Data)

You can’t calculate your retirement number without knowing what you’ll spend. Most people guess wrong — usually high on some categories and dangerously low on healthcare. Here’s what the Bureau of Labor Statistics Consumer Expenditure Survey shows for households headed by someone 65+:

Average annual spending: $57,818 ($4,818/month). Here’s where it goes:

Housing — $18,872/year (32.6%): The biggest line item by far. This includes mortgage or rent, property taxes, utilities, and maintenance. If you own your home outright by retirement, this drops dramatically, which is why paying off the mortgage before you retire is such a powerful move.
Transportation — $8,338/year (14.4%): Car payments, insurance, gas, repairs. Drops a lot if you go down to one car or live somewhere with decent public transit.
Healthcare — $7,540/year (13.0%): And this is the number that keeps climbing. Fidelity’s 2024 estimate says a 65-year-old couple retiring today should expect to spend roughly $315,000 on healthcare throughout retirement. That number shocks people every time.
Food — $7,166/year (12.4%): Groceries and restaurants combined.
Entertainment and travel — $3,458/year (6.0%): Usually highest in the first decade of retirement when you’re healthy and active, then tapers off.
Insurance and pensions — $3,038/year (5.3%)
Everything else — $9,406/year (16.3%): Clothing, gifts, personal care, miscellaneous.

A common rule of thumb: plan for 70-80% of your pre-retirement income. Making $100,000 now? Budget $70,000-$80,000/year in retirement. You’ll no longer pay payroll taxes, commuting costs, or retirement contributions, but healthcare and leisure spending tend to fill that gap.

Social Security: It Covers More Than You Think

Social Security gets dismissed a lot — “it won’t be there when I retire” is practically a meme at this point. But it’s still paying out, and for most retirees, it covers a significant chunk of expenses. Here are the actual 2025 numbers:

Average benefit: $1,976/month ($23,712/year)
Maximum at age 62 (early): $2,831/month ($33,972/year)
Maximum at age 67 (full retirement age): $3,822/month ($45,864/year)
Maximum at age 70 (delayed): $4,873/month ($58,476/year)

Here’s what nobody tells you about Social Security: every year you delay past your full retirement age (66-67 for most people), your benefit grows by 8%. That’s a guaranteed, inflation-adjusted 8% annual return. You can’t get that anywhere else on the planet. Delaying from 62 to 70 increases your benefit by roughly 77%.

For a couple both receiving average benefits, Social Security provides about $47,424/year. If your target spending is $60,000, you only need to cover a $12,576 gap from savings — which means you need $314,400 using the 4% rule, not $1,500,000. Social Security dramatically shrinks the number you actually need in your portfolio. Knowing your expected benefit is one of the most important steps in retirement planning.

Retirement Savings Benchmarks by Age

Fidelity Investments publishes the most widely cited age-based savings milestones. Here’s where you should be at each age, based on your salary:

Age 30: 1x salary. Earning $55,000? Have $55,000 saved.
Age 35: 2x salary. Earning $65,000? Target $130,000.
Age 40: 3x salary. Earning $75,000? Target $225,000.
Age 45: 4x salary. Earning $85,000? Target $340,000.
Age 50: 6x salary. Earning $90,000? Target $540,000.
Age 55: 7x salary. Earning $95,000? Target $665,000.
Age 60: 8x salary. Earning $100,000? Target $800,000.
Age 67: 10x salary. Earning $100,000? Target $1,000,000.

If you’re behind — and the median American aged 55-64 has only $185,000 saved according to the Federal Reserve, so plenty of people are — don’t spiral. The most important factor isn’t where you are right now. It’s what you do from here. Someone who starts aggressively saving at 45 can still build a solid retirement by maxing out their 401(k) at $23,500/year ($31,000 if you’re 50+ with catch-up contributions) and investing in low-cost index funds.

Closing the Gap: What Actually Works

If there’s a gap between where you are and where you need to be, these are the highest-impact moves:

Max Out Tax-Advantaged Accounts

In 2025, you can put $23,500 into a 401(k) and $7,000 into an IRA ($8,000 if you’re 50+). If your employer matches 401(k) contributions — and according to Vanguard’s How America Saves report, the average match is 4.7% of salary — take every penny of that match. On a $75,000 salary, that’s $3,525/year in free money your employer literally hands you. Not maxing the match is the financial equivalent of finding a $100 bill on the ground and walking past it.

Don’t Be Too Conservative Too Early

A common rule: subtract your age from 110 to get your stock allocation. At 35, that’s 75% stocks, 25% bonds. At 55, it’s 55/45. Stocks have returned 10% annually versus 5% for bonds historically. Being too conservative in your 30s and 40s has an enormous cost.

Real numbers: $500/month invested at age 30 in an S&P 500 index fund averaging 10% reaches roughly $1,130,000 by 65. That same $500/month in bonds at 5% gets you only $570,000. Same contribution, half the result — just because of asset allocation.

Kill the Mortgage Before You Retire

A $1,500/month mortgage payment in retirement requires an extra $450,000 in savings using the 4% rule. That’s a staggering amount of additional money you need just to make housing payments. Entering retirement with a paid-off house is one of the single most powerful things you can do for your financial security.

Think About Downsizing

Once the kids are gone, do you really need 3,000 square feet? Selling and moving to something smaller can unlock $100,000-$300,000 in home equity while cutting property taxes, utilities, and maintenance. Read our piece on renting vs buying in 2025 to see whether downsizing to a rental might make sense for your situation.

Work Even 2-3 Extra Years

I know, not what you want to hear. But the math is compelling. Working from 65 to 68 gives you three more years of saving, three more years of investment growth, and three fewer years of withdrawals. That triple benefit can increase your retirement income by 20% to 30%. Even part-time work at $20,000/year dramatically reduces how much you’re pulling from your portfolio.

The Three Phases of Retirement Spending

Here’s something most retirement planning articles skip: your spending won’t be the same every year. Financial planners call it the “retirement spending smile” because of the shape it makes on a graph:

The “Go-Go” Years (65-75): You’re healthy, energetic, and finally free. This is when people travel, pick up hobbies, renovate the house, and generally spend the most. Budget 100-110% of your baseline during this phase.
The “Slow-Go” Years (75-85): Activity naturally decreases. Travel slows down, you eat out less, and spending drops to 75-85% of initial retirement levels. This is the valley of the smile.
The “No-Go” Years (85+): General spending keeps dropping, but healthcare costs spike hard. Assisted living runs $5,000-$12,000/month. Total spending can climb back to 90-100% of baseline or higher, driven almost entirely by medical expenses.

This matters because it means the 4% rule is actually conservative for most people. You’ll likely spend more than 4% early on and less in the middle, which historically works out fine because the portfolio has years to recover during the lower-spending phase.

Frequently Asked Questions

Can I retire with $500,000?

Yes, but it’ll be tight. The 4% rule gives you $20,000/year from a $500,000 portfolio. Add average Social Security ($23,712/year), and you’re at about $43,712 annually. That’s workable if your home is paid off and you live somewhere affordable — think Midwest, not Manhattan. In a high-cost city or with significant healthcare needs, $500,000 alone won’t cut it.

How much does the average American have saved for retirement?

According to the Federal Reserve’s Survey of Consumer Finances, the median retirement savings for ages 55-64 is about $185,000, and the average is $537,000 (pulled up by wealthy outliers). For ages 65-74, the median is $200,000 and the average is $609,000. Both numbers are well below what most people need, which is why working longer and adjusting lifestyle expectations in retirement is so common.

What is the 25x rule for retirement?

It’s the flip side of the 4% rule. Take your expected annual retirement spending, multiply by 25, and that’s your savings target. Planning to spend $60,000/year? You need $1,500,000. But here’s the key: this is the amount you need FROM SAVINGS, not total income. Social Security covers a portion of your spending, so the amount you actually need saved is typically 30-50% lower than the headline number suggests.

At what age can I retire with $1 million?

At $1 million with the 4% rule, you can withdraw $40,000/year. Add Social Security at full retirement age ($23,712/year average), and you’re at about $63,712 annually — comfortable in most parts of the country. If you’re trying to retire early at 55 before Social Security kicks in, $1 million only gives you $40,000/year (and you might want to lower that to $35,000 with a 3.5% rate for safety). It’s doable but requires discipline.

How do I catch up on retirement savings at 50?

Max out everything: $31,000/year in your 401(k) (includes the $7,500 catch-up for 50+), $8,000 in an IRA. That’s $39,000/year in tax-advantaged accounts. Invest aggressively in low-cost index funds — Vanguard’s VTSAX or Fidelity’s FZROX. Over 15 years at 10% average returns, $39,000/year grows to approximately $1,245,000. Also delay Social Security to 70 to boost your benefit by 77%. It’s not too late, but it requires real commitment starting now.

Find Your Number and Take the First Step

Retirement math doesn’t have to be paralyzing. Start with your expected annual spending, subtract what Social Security will cover, multiply the gap by 25, and you’ve got a solid target. For most people, that number lands between $500,000 and $2,000,000 depending on lifestyle, location, and whether the house is paid off.

The single most useful thing you can do right now is find out where you stand. Use our Retirement Calculator to plug in your age, savings, monthly contributions, and target retirement age. In a few minutes you’ll know if you’re on track, ahead, or behind — and exactly what adjustments to make. The earlier you know your number, the easier it is to hit it.
