Retire at 62 vs 70: What 1,000 Simulated Futures Say

Claim Social Security at 70 instead of 62 and your monthly check can be about 77% bigger for the rest of your life. That one number drives most of the retire at 62 vs 70 debate, and it matters for you because it's permanent. It's the floor your other savings sit on for the next 25 to 30 years or more.

A bigger check doesn't decide it, though. The question underneath is simpler: will your money last? That's a question about odds, not averages, and it's the one most "62 vs 70" articles skip.

The short answer

• Claiming at 70 gets you the biggest guaranteed, inflation-adjusted income. It protects you best if you live a long time.
• Claiming at 62 gets you money sooner, while you're younger and possibly healthier. The trade is a permanently smaller check.
• Retiring and claiming are separate decisions. You can stop working at 62 and still wait until 70 to claim. For many people that's the option worth testing.

What's right for you depends on your savings, spending, health and household. A rule of thumb can't settle it. Your own numbers can.

Retire at 62 vs 70: the Social Security numbers

If your full retirement age is 67, claiming at 62 cuts your benefit by about 30%. Each year you wait past 67 adds 8%, up to age 70, so the three years from 67 to 70 add 24% in total (FedWeek; Kiplinger). That's how you get from roughly 70% of your full benefit to roughly 124%, and 124 divided by 70 is where "77% more" comes from (NerdWallet).

Sources: averages from Nasdaq, citing SSA data; maximums from The Motley Fool. Check your own figures against your SSA statement.

A quick caveat on the averages. They describe different groups of people who claimed at different ages, not one person choosing between two options. Your own statement is the number that counts.

How the reduction actually works

The cut for claiming early isn't one flat penalty. It's charged by the month:

• 5/9 of 1% per month for the first 36 months before full retirement age
• 5/12 of 1% per month for each month earlier than that
• 2/3 of 1% per month in delayed retirement credits after full retirement age, which works out to 8% a year

Each month you wait moves the number. You don't have to choose 62 or 70. Any month in between is an option.

Why break-even age is the wrong question

Most top-ranking pages give you a break-even age, the point where the larger checks from waiting finally add up to more than the smaller checks you'd have collected starting at 62. For 62 vs 70, that's usually put at around 80 to 81 (FinanceBuzz).

It's tidy. It's also a bet on when you'll die.

Break-even math asks: "Which option pays me more in total?" What a retiree actually needs to know is: "Which option makes it less likely I run out of money?" Those two questions can have different answers.

Running out of money at 88 is far worse than leaving some unused benefit on the table at 75. Break-even math scores both outcomes the same way. It also usually ignores taxes, inflation and investment returns, and it says nothing about what happens to your savings in the meantime.

Longevity is no edge case, either. According to the Social Security Administration's Retirement Information for Medicare Beneficiaries (2026), about 1 in 3 65-year-olds may live to 90 or beyond. If that's you, every year past break-even makes the larger check more valuable.

Retiring and claiming are two different decisions

This is the scenario most comparison pages leave out: retire at 62, claim at 70.

You stop working, live on your savings for eight years, then switch on a check that's about 77% larger for life. You're using your portfolio to buy a bigger guaranteed income.

It has real costs:

• Eight years of full withdrawals. From 62 to 70, savings pay for everything. That's 96 months of spending with no Social Security to soften it.
• A smaller portfolio at 70. You reach 70 with less invested, but much less pressure on it from then on.
• Health insurance until 65. If you stop working at 62, you'll need your own coverage until Medicare begins at 65 (Fox Business).

Whether that trade works depends on how much you have and how markets behave during those first years. A single average-return projection can't tell you that. A simulation can.

What changes when you run it through 1,000 futures

A Monte Carlo simulation, in plain terms, plays your retirement forward many times with different market paths: good decades, bad decades, crashes early, crashes late. Then it counts how often your money lasts. You get a success rate, not a single forecast.

Here's what that approach catches that break-even math misses.

Eight more years of withdrawals

Morningstar's The State of Retirement Income 2025 (December 2025) puts the safe starting withdrawal rate at 3.9%, meaning the rate at which money is still there in 90% of simulated outcomes over a 30-year retirement.

Look at the horizon. Retire at 62, plan to 95, and that's 33 years. Retire at 70, and it's 25. Retiring earlier makes the stretch your money has to cover longer than the one that 3.9% figure was tested against. Earlier retirement isn't ruled out. It just means you have less room for error.

The first few years matter most

If markets fall hard right after you retire, you're selling investments at low prices to pay the bills. Those losses compound. Retiring at 62 and drawing on savings until 70 puts more of your money at risk during exactly that early, fragile window.

Two retirees with the same average return over 30 years can end up in very different places, depending on when the bad years land. Only a test that runs many paths shows you that spread.

Planning to 95, not 85

A plan that stops at 85 quietly bets against the third of 65-year-olds who may reach 90. The plan you build with Monte Climb runs to 95 by default, and you can push it further. That's also where waiting for a bigger check tends to help most. Late in life, a larger guaranteed income takes pressure off whatever savings are left.

Health care is a line item

Fidelity's 2025 Retiree Health Care Cost Estimate (July 2025) puts health care for one 65-year-old at $172,500 over retirement. That covers Medicare premiums, deductibles and prescriptions, and it doesn't include long-term care. Retiring at 62 adds coverage costs from 62 to 65 on top of that.

Our engine charges Medicare premiums and income-based surcharges year by year instead of using one flat guess. That matters here, because the income you draw in each year can change what you pay.

What the break-even calculators leave out

A few more factors can push the answer one way or the other:

• Married couples. When one spouse dies, the survivor generally keeps the larger of the two benefits. So the higher earner's choice to delay affects two lifetimes, not one. Single-person break-even math undersells this.
• Taxes. The years between retiring and claiming can be unusually low-income. Some people use them for Roth conversions or to draw down traditional IRAs, which can lower required withdrawals later. Talk this through with a tax professional before acting on it.
• Working while claiming early. If you claim before full retirement age and keep earning, the earnings test can temporarily withhold part of your benefit. Check SSA's current limit first.
• Trust fund uncertainty. Some people claim early because they worry benefits will be cut. That's a fair thing to stress-test. Run a version of your plan with lower benefits and see whether it still holds.
• Health and your own life. Statistics describe groups. If you have reason to expect a shorter life, or you want the years from 62 to 70 for things you can't do later, that belongs in the decision too.

How to test retiring at 62 vs 70 on your own numbers

You don't need a spreadsheet to start. Three numbers:

1. Your age
2. What you've saved for retirement
3. What you spend each month

That's a first step about half of workers haven't taken. EBRI's 2025 Retirement Confidence Survey found only 52% of workers have estimated the monthly income they'll need in retirement.

Then compare versions of the plan:

• Retire at 62, claim at 62
• Retire at 62, claim at 70 (the bridge)
• Work to 67 or 70, claim at 70

Look at the success rate for each, then break each plan on purpose. Lower returns, higher health costs, a longer life. The version that holds up across the most futures is the one worth a closer look.

If you'd rather talk it through, ask William, our AI planner, something like "Can I retire at 62?" or "Am I on track?" He shows his work, so you can see why the answer comes out the way it does.

Whatever you get back is a probability, not a promise. It's also planning software, not advice. It gives you a clearer picture to take into the decision, or to a professional if you want one.

Frequently asked questions

How much more is Social Security at 70 than at 62?

If your full retirement age is 67, claiming at 62 pays about 70% of your full benefit and claiming at 70 pays about 124%. That makes the age-70 check roughly 77% larger, every month, for life.

What is the break-even age for claiming Social Security at 62 vs 70?

It's usually estimated at around 80 to 81. Break-even math only tells you which option pays more in total, though. It doesn't tell you which option makes it less likely you'll run out of money, and for most retirees that's the more important question.

Can I retire at 62 but wait until 70 to claim Social Security?

Yes. Retiring and claiming are separate decisions. Many people stop working at 62, live on savings until 70, and then claim the larger benefit. The cost is eight years of full withdrawals from your portfolio, plus paying for your own health insurance until Medicare starts at 65.

Is it better to retire at 62 or 70?

It depends on your savings, spending, health and household. Waiting gets you the biggest guaranteed income and the best protection if you live a long time. Retiring at 62 means your savings have to cover a longer stretch and you have less room for bad market years. Testing both scenarios against many simulated futures shows which one holds up better for your numbers.

What do I need to pay for health insurance if I retire at 62?

Medicare doesn't start until 65, so if you retire at 62 you'll need your own coverage for those three years. After 65, Fidelity's 2025 estimate puts health care costs for one 65-year-old at $172,500 over retirement, not counting long-term care.
