Quick answer
From your date of birth and the age you plan to retire at, the calculator finds your retirement date: born 14 May 1990, retiring at 67, that is Monday 14 May 2057. It also shows the time left, 11,146 days as of 7 November 2026, and the official pension ages to enter.
How it works
Tell the calculator two things: your date of birth and the retirement age you plan to retire at. It adds that age to your birth date to find your retirement date. Statutory retirement ages differ by country.
The United States uses a graduated scale, so its full retirement age depends on the year you were born. The United Kingdom applies its state pension age in steps linked to exact birth dates. Most other countries use one flat statutory age. Check the official age that applies to you, then enter that age here.
You get two things back: your exact retirement date, and how much time stands between today and that date, in years, months and days. If that date has already passed, the tool tells you that you are already past retirement age. The retirement age must be a whole number from 40 to 100.
Worked example: born 14 May 1990, retiring at 67
Someone born on 14 May 1990 who plans to retire at 67 reaches that age on Monday 14 May 2057. As of 7 November 2026, that is 30 years, 6 months and 7 days away, or 11,146 days, 1,592 weeks and 2 days.
The United States full retirement age for someone born in 1990 is 67, so the statutory date and the planned date are the same here.
The United Kingdom State Pension age for the same birth date is 68, because it applies to people born after 5 April 1978, so a UK reader would enter 68 and get 14 May 2058 instead.
Retirement ages by country
The table below lists the statutory retirement age behind the full public pension in each country. Use it to pick the age to enter in the calculator.
| Country | Statutory retirement age | What it covers |
|---|---|---|
| United States | 66 to 67, graduated by birth year | Full retirement age for Social Security |
| United Kingdom | 66, rising to 67 and 68 | State pension age, phased in by birth date |
| Canada | 65 | Old Age Security and Canada Pension Plan |
| Australia | 67 | Age Pension; superannuation access rules differ |
| Germany | 67 | Statutory pension age |
| France | 64 | Legal minimum retirement age |
| Japan | 65 | National pension age |
These are statutory ages, and your own situation can shift the details. Early retirement options, contribution records, and special schemes all change what you actually receive and when you can claim it.
Enter the age that applies to you, and the calculator works out your retirement date from it. Your pension provider fills in the rest.
Why retirement ages differ
Every country sets its pension age from its own mix of life expectancy, birth rates, and budget pressure. Longer lives and fewer workers per retiree push the age upward, which is why so many countries moved from 65 to 67 in recent decades.
France sits lower at 64 after years of political debate, while the United Kingdom and the United States phase their increases in gradually to protect people close to retirement.

Claim at 62 vs 67 vs 70: Cumulative Lifetime Benefits
Cumulative lifetime benefits and the crossover ages in one table. Born 1960, Primary Insurance Amount $2,000 (COLA ignored for clarity):
| Claim age | Monthly benefit | Total by 80 | Total by 85 | Total by 90 |
|---|---|---|---|---|
| 62 | $1,400 | $302,400 | $386,400 | $470,400 |
| 67 | $2,000 | $312,000 | $432,000 | $552,000 |
| 70 | $2,480 | $297,600 | $446,400 | $595,200 |
Break-even: the age-70 claimer overtakes the age-62 claimer at about 80.4. The $134,400 head start closes at $1,080 per month. The age-67 claimer overtakes the age-62 claimer earlier, at about 78.7: at 67 the early claimer has already received $84,000, and the gap closes at $600 a month.
Worked Example: Born 1965 (FRA = 67), PIA $2,000
Claim at 62: 60 months early. First 36 months cost 5/9 of 1% each (20%), remaining 24 cost 5/12 of 1% each (10%). Total 30% cut: $1,400/month for life. Claim at 67: $2,000.
Delay to 70: 36 months x 2/3 of 1% = 24% boost: $2,480/month. Born 1957: FRA = 66 and 6 months. Born January 1, 1960: treated as December 1959, FRA 66 and 10 months.
Can you afford to retire at that age?
The calculator finds the date; it does not check whether your savings can fund it.
The rule of thumb most planners use is the 25x rule: the nest egg you need is 25 times the annual income your savings must produce, which is the 4% rule stated the other way round. Social Security lowers the target, because it covers part of your spending.
| Spending a year | Nest egg (25x) | Social Security a month | Portfolio must fund | Portfolio target (25x) |
|---|---|---|---|---|
| $40,000 | $1,000,000 | $1,500 | $22,000 a year | $550,000 |
| $50,000 | $1,250,000 | $1,500 | $32,000 a year | $800,000 |
| $60,000 | $1,500,000 | $2,000 | $36,000 a year | $900,000 |
| $80,000 | $2,000,000 | $2,000 | $56,000 a year | $1,400,000 |
Take the $50,000-a-year row: the target is $800,000 after Social Security. A 35-year-old with $60,000 saved, adding $1,000 a month at 7% a year, reaches $800,000 in about 20 years and 7 months, at about age 55 and 7 months.
Saving $1,500 a month instead reaches the same target in about 17 years and 3 months, at about age 52 and 2 months, roughly 3.5 years earlier. These figures assume a steady 7% return with monthly compounding and ignore inflation, taxes and fees, so treat them as a planning illustration, not a forecast.
The 25x rule is a rule of thumb, not a guarantee: it comes from the Trinity study’s finding that a 50/50 stock-bond portfolio survived 30-year retirements at a 4% withdrawal rate across US history.
Retirement Age Facts
Full Retirement Age
The age for 100% of the Primary Insurance Amount: 66 for 1943-1954, stepping 2 months per year for 1955-1959, 67 for 1960 and later.
The 1983 Amendments
Congress phased FRA from 65 to 67 to account for rising life expectancies.
Delayed Retirement Credits
2/3 of 1% per month past FRA (8% per year), up to age 70. No benefit to waiting past 70.
2026 COLA
2.8% Benefits grow with annual cost-of-living adjustments on top of the claiming-age math.
Retirement earnings test
Claiming early while still working triggers a separate reduction mechanism.

The official pension ages to enter
The tool does not look up the official pension ages for you: it adds the age you enter to your date of birth. Use the schedules below to pick the right age, then enter it in the calculator.
United States: the Social Security full retirement age, from 66 for people born from 1943 to 1954, rising by two months a year to 67 for people born in 1960 or later. Social Security treats a 1 January birthday as belonging to the previous year.
United Kingdom: the State Pension age, 66 for people born from 6 October 1954 to 5 April 1960, rising in monthly steps to 67 for people born from 6 March 1961, and scheduled to rise to 68 for people born after 5 April 1978, with a phased change for births in 1977 and 1978.
Pension ages are set by law and can change. Check the official State Pension age or Social Security tools before making plans.
What other retirement age calculators offer
Most retirement age calculators on the first page answer a different question from this one: they work out the age at which your savings can fund retirement. What sets them apart is what they ask for and what they show. The comparison below is against the three retirement age calculators that rank highest.
| Feature | Age-Finder | CompoundInterestCalc | ShrinkBee | CalcMyAge |
|---|---|---|---|---|
| Retirement date from a DOB and an age | Yes | Not shown | Not shown | Yes |
| Time left in years, months and days | Yes | Yes, years and months | Yes | Not shown |
| Official FRA by birth year | Yes, in the guide | Not shown | Yes | Yes |
| Claim at 62 vs 67 vs 70 | Yes, in the guide | Not shown | Yes | Not shown |
| Savings and nest egg modelling | No, in the guide | Yes | Yes | Not shown |
| Affordable retirement age from savings | No | Yes | Yes | Not shown |
| How long the money lasts | No | Yes | Yes | Not shown |
| Free, no sign-up or account | Yes | Yes | Yes | Yes |
The limits, stated plainly: the tool models no savings and no nest egg, so it cannot say whether you can afford to retire at the age you enter; it shows no claiming-age benefit amount and no affordable retirement age from savings; and it has no live ticking count to the date.
What it adds is the exact retirement date and the time left to it, with the official pension ages, the claiming-age tradeoff and the 25x rule worked through by hand in the guide.
Frequently asked questions
How is my retirement age determined?
Your retirement age is the age you enter: the age you plan to retire at, or the statutory age for your country. The calculator adds that age to your date of birth and returns the calendar date you reach it.
Countries that phase in changes by birth year or birth date, like the United States and the United Kingdom, set different ages for different birth years, so check the official schedule for your birth year before you enter your age.
What if I was born on Feb 29?
If you were born on February 29 and your retirement year is not a leap year, the calculator sets your retirement date to February 28 and shows a note explaining the adjustment. Your retirement age itself does not change. Only the calendar date shifts, because February 29 does not exist in that year.
Does the US retirement age depend on my birth year?
Yes. The United States sets full retirement age on a graduated scale. It is 66 for people born from 1943 through 1954, then rises by two months for each later birth year, reaching 67 for everyone born in 1960 or later.
Look up the step that applies to your birth year, then enter that age in the calculator.
What is the difference between this and the retirement countdown?
This tool answers the question “when do I retire” by finding your official retirement age and date. The retirement countdown answers “how long until then” with a live day-by-day count to the date you choose.
Use this calculator first to find your date, then plug that date into the countdown to watch the days tick down.
Is my date of birth stored anywhere?
No. Everything runs in your browser. Your date of birth never leaves your device, nothing is sent to a server, and nothing is saved or logged. Close the tab and the information is gone.
Does the calculator show my official pension age?
No. The calculator adds the age you enter to your date of birth; it does not look up the Social Security full retirement age or the UK State Pension age for you. The official pension ages section above gives both schedules, so you can pick the right age and enter it.
Plan around your date
Knowing your official retirement date is the starting point, not the finish line. Once you have it, you can work backward: check your pension statements, estimate the income your savings must produce, and talk with a financial adviser about closing any gap between now and then.
Rules change over time, so recheck your date every year or two, and again after any move to a new country.
This page gives general information about statutory pension ages and the claiming-age arithmetic. It is not financial advice, and it does not take your savings, earnings record, taxes or health into account. Pension ages are set by law and can change, so check the official Social Security and GOV.UK tools before making plans.
