What MRA+10 means in planning
MRA+10 is a FERS path for employees who have reached minimum retirement age and have at least 10 years of service, but do not meet a longer-service unreduced immediate retirement path.
This calculator page is for the moment when you want to test dates. For a broader explanation of immediate versus postponed MRA+10, use the related MRA+10 retirement guide.
What the calculator can and cannot settle
The calculator can show an educational estimate for supported V1 MRA+10 scenarios. It can also flag unsupported cases rather than guessing.
It does not replace HR review of your service history, benefit continuation, deposits, redeposits, survivor elections, or official application timing.
What to compare after the first MRA+10 estimate
For many MRA+10 questions, the most useful next step is not another article. It is comparing the same facts with a different annuity start date so the reduction and timing questions become visible.
Use the result page to write down which questions are about income timing and which are about benefits, paperwork, or official records. Keeping those categories separate prevents one estimate from looking more certain than it really is.
How this differs from deferred retirement
MRA+10 postponed and deferred retirement can both involve a later annuity start, but they are not interchangeable labels.
If you are unsure which path fits, compare this page with the postponed versus deferred guide before treating an estimate as a decision.
Example: MRA+10 timing question
A FERS employee born in 1968 with 17 years of service may be looking at MRA+10 rather than regular immediate retirement if they do not have enough service for an unreduced immediate path.
The practical question is whether the annuity starts right away or is postponed. That timing choice can affect the estimate and what benefit-continuation questions the employee should bring to HR.
MRA+10 immediate versus postponed planning
| Question | Immediate MRA+10 | Postponed MRA+10 |
|---|---|---|
| When the annuity starts | The annuity starts soon after separation if the application path supports it. | The annuity start is delayed to a later date selected by the retiree. |
| Why people compare it | Starting sooner can help cash flow but may involve an age reduction before age 62. | Waiting can change the reduction picture but creates a gap to plan around. |
| What to verify | Eligibility, reduction, FEHB, FEGLI, and application timing. | Postponed start date, benefit-continuation rules, and required paperwork. |
Common questions
What is MRA+10 under FERS?
MRA+10 is a FERS planning path for employees who have reached minimum retirement age and have at least 10 years of service but do not meet a longer-service unreduced immediate retirement path.
Why compare immediate and postponed MRA+10?
Starting an MRA+10 annuity right away can create cash flow sooner, but a postponed start may change the age-reduction question. Benefit-continuation and paperwork timing still need separate official review.
Can the MRA+10 calculator decide my FEHB or FEGLI eligibility?
No. The calculator can organize the retirement-date estimate, but FEHB, FEGLI, survivor, refund, and official application questions should be confirmed with OPM materials and your agency benefits office.
