Two ages for each birth year: the FERS MRA from OPM and the Social Security age from SSA

The FERS minimum retirement age in the table comes from OPM’s chart by year of birth, and the Social Security full retirement age comes from SSA’s table. For every year from 1966 to 1970 Social Security’s age is 67, while the FERS age rises from 56 and 4 months to 57. Enter your date of birth on the FERS minimum retirement age page to see the date your MRA falls on.

What is the FERS minimum retirement age for each birth year from 1966 to 1970?

OPM’s chart sets the minimum retirement age (MRA) by year of birth. It gives 56 and 4 months for 1966, 56 and 6 months for 1967, 56 and 8 months for 1968 and 56 and 10 months for 1969. For 1970 and after it is 57, so 1970 is the first of these years with a whole-year MRA. The table above gives each year its own row, read from the same OPM chart that the FERS minimum retirement age page uses.

Does the MRA change with the month of birth?

Not in OPM’s chart. The chart gives one age for each calendar year of birth, so everyone born in 1967 has the same MRA, 56 and 6 months, whatever the month. OPM’s page does not say how to count the MRA for a birth on the 1st of a month or on January 1, so this page does not move the age for those days. The FERS tool adds the MRA to your birth date and tells you to confirm the day with your agency.

What is the Social Security full retirement age for these years?

SSA’s table gives 67 for people born in 1960 and later, so 67 applies to every birth year from 1966 to 1970. For a birth on January 1, SSA uses the previous year’s row, which is also 67, so the age stays the same. For a birth on the 1st of any month, SSA counts the birthday as falling in the previous month, which moves the month you reach 67 one month earlier and does not change the age. The Social Security age is set by SSA and is a separate program from the FERS MRA.

Which immediate retirement ages apply to these birth years?

OPM lists four sets for an immediate FERS retirement benefit: age 62 with 5 years of service, age 60 with 20 years, your MRA with 30 years, or your MRA with 10 years. For the MRA with 10 years, OPM says the benefit is reduced 5 percent a year for each year under 62, unless you have 20 years of service and the benefit starts at 60 or later. Your MRA is the age from the table above, so for 1966 to 1970 it runs from 56 and 4 months to 57.

How do I find the date for my own birthday?

Open the FERS minimum retirement age page and enter your date of birth. It shows your MRA and the date your birth date plus that age falls on. If you also enter your service computation date, it shows the first date for each of the four immediate sets. The date of birth stays in your browser: it is not sent, saved or put in the address.

Questions about fers mra, 1966 to 1970

What is the FERS MRA for someone born in 1966?

56 and 4 months. OPM’s chart gives 56 and 2 months for 1965, so 1966 is two months later.

What is the FERS MRA for someone born in 1967?

56 and 6 months, two months more than for a 1966 birth.

What is the FERS MRA for someone born in 1968?

56 and 8 months, the age OPM’s chart gives for births in 1968.

What is the FERS MRA for someone born in 1969?

56 and 10 months, the last 2-month step in OPM’s chart before the MRA becomes 57.

What is the FERS MRA for someone born in 1970?

57. OPM’s chart gives 57 for births in 1970 and after.

Does this page show my annuity?

No. It shows ages and dates, not a dollar amount. OPM publishes calculators, including the Federal Ball Park Estimator, and your agency’s benefits office can give you an estimate.

Is the MRA the same as my Social Security age?

No. They come from two programs with two tables. OPM’s chart runs from 55 to 57 for the MRA, and Social Security’s full retirement age runs from 65 to 67.
