Retirement Age Calculator
Find the exact date you reach any retirement age — and how long you have to wait.
The Retirement Age Calculator converts a target retirement age into the concrete calendar date — and tells you exactly how long remains until you get there. Enter your date of birth and the age you plan to retire at, and the tool returns your retirement date with its weekday, the remaining time in years, months and days, and the total days to go.
For US readers, Social Security's full retirement age is a useful anchor: it rises from 66 for people born before 1955 to 67 for anyone born in 1960 or later, and claiming earlier permanently reduces monthly benefits while delaying past FRA increases them. But retirement age is ultimately a personal financial choice — some people target 55 or 60 with their own savings, others plan to work into their 70s. The field accepts any age from 40 to 75.
The countdown makes the plan tangible: seeing thousands of days to go turns a vague someday into a number you can schedule around. The calculation runs entirely in your browser and uses precise calendar math.
US full retirement age for Social Security is 67 for people born in 1960 or later.

Frequently asked questions
What is the US full retirement age?
Full Retirement Age (FRA) for Social Security is 66 to 67 depending on birth year: 66 for those born 1943–1954, rising two months per year through 1959, and 67 for anyone born in 1960 or later. Claiming before FRA reduces monthly benefits; delaying past it (up to 70) increases them.
Can I retire earlier than full retirement age?
You can start Social Security as early as 62, but benefits are permanently reduced (about 25–30% less if you claim at 62 versus FRA). Many people who retire early do so on personal savings, pensions or part-time income rather than Social Security — the calculator works with any age you choose.
How is the retirement date calculated?
The tool adds your target age in calendar years (and any fractional months) to your birth date, the same way an age is read back from a date of birth. Retiring at 67 exactly means your retirement date is your 67th birthday.
Is this a financial planning tool?
It answers the calendar question only — when you reach an age. Whether you can afford to retire at that age depends on savings, expected returns, spending and other income. Pair it with the FIRE calculator and Savings Calculator for the financial side.
