Figuring out what's the best age to retire is one of the most consequential financial decisions you'll ever make. According to Gallup's 2024 Economy and Personal Finance survey, the average retirement age reported by retirees in the United States was 62, yet many financial planners argue that number is shifting.
The problem is that "best" depends heavily on your health, savings, lifestyle goals, and where you live. There is no universal magic number.
This article breaks down five key facts you need to understand: how Social Security timing works, the role of Medicare eligibility, the impact of early versus delayed retirement, common mistakes to avoid, and how to calculate your personal target age.
Understanding the Core Retirement Ages That Matter
The question of what's the best age to retire often starts with three government-defined ages. In the United States, age 62 is when you can first claim Social Security retirement benefits. Age 65 is when Medicare eligibility typically begins. And somewhere between 66 and 67 is your "full retirement age" (FRA), depending on your birth year.
The Social Security Administration (SSA) sets these thresholds, and they anchor most retirement planning conversations. Claiming at 62 permanently reduces your monthly benefit by roughly 25% to 30% compared to waiting until your FRA. Delaying past your FRA increases benefits by about 8% per year up to age 70.
A common scenario: someone born in 1962 reaches their FRA at 67. If they claim at 62, their benefit might drop from $2,000 to $1,400 monthly. That's a difference of $7,200 per year for life. How to apply this: find your own FRA using the Social Security Administration's retirement age calculator before making any claiming decision.
Understanding these thresholds is essential when weighing what's the best age to retire for your specific situation.
How Health and Life Expectancy Shape Your Ideal Retirement Age
Your health status matters more than any calendar number when determining what's the best age to retire. The Centers for Disease Control and Prevention (CDC) reports that average life expectancy in the U.S. was approximately 78.4 years as of 2023. That means a 62-year-old retiree could need 16-plus years of income.
If you have a family history of longevity and are in good health, delaying retirement to 67 or 70 can substantially increase your lifetime Social Security income. Conversely, if health challenges run in your family, claiming earlier may make sense even with reduced benefits.
Consider one retiree's situation: a 60-year-old with controlled hypertension and two living parents in their 90s. Waiting until 70 maximizes guaranteed lifetime income and protects against outliving savings. Meanwhile, someone with a chronic condition limiting life expectancy might reasonably claim at 62.
How to apply this: review your family health history and get a preventive physical exam to better estimate your longevity horizon. This health data often reveals what's the best age to retire for you personally.
The Financial Impact of Early vs. Delayed Retirement
The financial gap between retiring at 62 and retiring at 70 is dramatic, and understanding it is central to knowing what's the best age to retire. Each year you delay, three things happen: you avoid withdrawing from your portfolio, you continue contributing to retirement accounts, and your Social Security benefit grows.
According to data from Fidelity Investments, a worker who delays retirement from 62 to 70 can increase their monthly Social Security benefit by approximately 76% in nominal terms. That's the cumulative effect of delayed retirement credits. Additionally, working longer shrinks the number of years your savings must cover.
When projecting these numbers, many people realize that what's the best age to retire depends heavily on their portfolio size.
| Retirement Age | Social Security Impact | Portfolio Impact | Action to Take |
|---|---|---|---|
| 62 | Benefit reduced ~30% from FRA | Savings must last 25+ years | Only choose if health or cash flow demands it |
| 65 | Benefit reduced ~13% from FRA | Medicare coverage begins | Consider if employer health insurance ends |
| 67 (FRA for many) | Full benefit, no reduction | Balanced withdrawal period | Strong default for average health and savings |
| 70 | Benefit increased ~24% above FRA | Shortest withdrawal period | Ideal if longevity runs in your family |
How to apply this: run a side-by-side projection of claiming at 62 versus 70 using Fidelity's Retirement Score tool to see the lifetime difference. Crunching these numbers often clarifies what's the best age to retire given your financial reality.
Common Mistakes People Make When Choosing a Retirement Age
Even well-informed people stumble when deciding what's the best age to retire. One frequent mistake is claiming Social Security early out of fear that benefits will run out, without understanding the SSA's actual funding status. Another is retiring before securing a plan for health insurance coverage between 62 and 65.
A third error is underestimating inflation. The Bureau of Labor Statistics reports that consumer prices rose substantially between 2021 and 2023, eroding purchasing power for fixed-income retirees. Retiring at 62 with a static pension may feel comfortable initially but becomes tight a decade later.
One case involved a couple who retired at 62 with $800,000 in savings. They withdrew 4% annually ($32,000) plus Social Security, but medical costs before Medicare and unexpected home repairs forced them to take part-time work at 66. Delaying to 65 would have cut their pre-Medicare coverage gap to zero.
How to apply this: before committing to an age, map out health insurance options and run a worst-case inflation scenario of 4% annually. Avoiding these pitfalls requires honestly asking what's the best age to retire rather than defaulting to the earliest possible date.
Tools and Resources to Calculate Your Personal Best Retirement Age
You don't have to guess. Several reputable tools can help you pinpoint what's the best age to retire based on your actual numbers. The AARP Social Security Calculator estimates your monthly benefit at different claiming ages using your earnings record.
For broader retirement readiness, Vanguard's Retirement Income Calculator projects whether your savings will last across various retirement ages and spending levels. Both tools are free and require only basic inputs.
The Consumer Financial Protection Bureau (CFPB) also offers a "Planning for Retirement" resource hub that includes worksheets for estimating expenses. As the CFPB states on its official site, "Your retirement age affects how long your savings need to last and how much you can safely withdraw each year."
How to apply this: spend 30 minutes this week entering your data into one of these calculators, then compare the recommended claiming age against your current plan. Running the numbers through multiple tools will give you confidence about what's the best age to retire for your circumstances.
Frequently Asked Questions About what's the best age to retire
What if I want to retire before 62?
Retiring before 62 means you cannot claim Social Security at all, so you'll need entirely self-funded income from savings, investments, or a pension. This is what's the best age to retire for those with substantial net worth, often $2 million or more.
You'll also need private health insurance, which can cost $1,000 to $2,000 monthly per person before Medicare kicks in.
Does my spouse's age affect my best retirement age?
Yes, especially for married couples. If one spouse earned significantly more, delaying the higher earner's claim to 70 maximizes the survivor benefit the lower earner receives after the higher earner dies. This strategy often shifts what's the best age to retire for the primary earner upward by three to five years compared to a single person's optimal age.
Can I change my mind after claiming Social Security early?
You have a 12-month window to withdraw your Social Security application and repay all benefits received, effectively resetting your claiming age. This is a rare but valuable option when someone realizes they claimed too early and wants to reconsider what's the best age to retire.
After 12 months, you cannot undo the decision, though you can suspend benefits at FRA to earn delayed credits.
How does working part-time affect my retirement age choice?
Earning income before your FRA triggers the Social Security earnings test, which withholds $1 in benefits for every $2 you earn above the annual limit. For 2025, that limit is around $23,400. This often pushes the practical answer to what's the best age to retire to your FRA, when the earnings test disappears entirely.
Is there a best age to retire for people with pensions?
Pension recipients often have more flexibility because their pension provides baseline income independent of Social Security. For them, what's the best age to retire may hinge on pension vesting rules and early retirement factors, which reduce monthly payouts for each year before the plan's normal retirement age, commonly 65. Review your specific plan document to see the reduction percentages.
