USA Retirement Date Calculators

Retirement date calculators for US workers: Social Security, FERS, military, USPS and teacher plans — each built on the official rules, dates only, no benefit amounts.

Which USA calculator should you use?

  • Private-sector worker? Social Security is your baseline — almost everyone has a full retirement age here.
  • Federal employee? FERS — or USPS if you're postal.
  • Service member? Military for the 20-year and reserve dates.
  • Teacher? Teacher — your state plan's pattern, your date.

Under more than one system? Run each calculator — many Americans have two or three different retirement dates.

Frequently asked questions

Do these cover benefit amounts?

No — deliberately. Every calculator here gives dates only: when you're eligible, when pensions start, how the milestones compare. Amounts depend on earnings, contributions and scheme formulas — check the scheme itself.

I'm under two systems. Which date counts?

Both — each system pays from its own date. Run each relevant calculator and plan around both milestones.

Are the rules up to date?

Each tool cites its official source and verification date. If the law changes, the rule data is updated — check the source links for the latest.
