Military buyback can increase a federal pension substantially for some veterans.
But many employees do not understand how the increase is actually calculated.
The answer depends on:
- Your high-3 salary
- Years of military service
- Retirement age
- Pension multiplier
How Military Buyback Works
Military buyback adds qualifying military service to your FERS retirement calculation.
That additional service increases:
- Total creditable years
- Pension amount
- Sometimes retirement eligibility
The Basic FERS Formula
The standard FERS pension formula is:
High-3 Salary × Years of Service × Multiplier
Most employees use:
- 1.0%
- Or 1.1% at age 62+ with at least 20 years
Military buyback increases the “years of service” portion of the formula.
Example Without Buyback
High-3 salary:
$100,000
Years of civilian service:
25
Calculation:
$100,000 × 25 × 1%
= $25,000/year
Example With 4 Years Bought Back
Now add:
- 4 years military buyback
Total service:
29 years
New calculation:
$100,000 × 29 × 1%
= $29,000/year
Difference:
+$4,000/year for life
Why Small Differences Matter
A $4,000 annual increase may not sound massive at first.
But over:
- 20 years
- 25 years
- 30 years
The lifetime difference can become substantial.
The 1.1% Multiplier Effect
If you retire at age 62+ with at least 20 years of service, you may qualify for the 1.1% multiplier.
Example:
$100,000 × 29 × 1.1%
= $31,900/year
That increases the value of the buyback even more.
The Deposit Cost Matters
Military buyback is not free.
You generally pay a deposit based on:
- Military earnings
- Interest (if delayed)
- Service dates
That means the pension increase should always be compared against the deposit cost.
Taxes Matter Too
Additional FERS pension income is generally taxable.
This is why net retirement income matters more than gross pension numbers.
Military Retirement Tradeoffs
If you already receive active-duty military retirement pay, you may need to waive that retirement to use the same years toward FERS.
That can dramatically change the analysis.
Always compare both scenarios carefully.
Why Buyback Helps Some Veterans Retire Earlier
Additional service credit may help veterans:
- Reach retirement eligibility sooner
- Increase pension income
- Reduce TSP withdrawal pressure
- Improve retirement readiness
This can create more retirement flexibility.
5 Common Misunderstandings
- Military buyback is always free money
- Pension increases are always massive
- VA disability is reduced
- Military retirement never matters
- Buyback decisions only affect pension size
Key Takeaway
Military buyback can meaningfully increase a FERS pension by adding creditable service years.
The real value depends on:
- Pension increase
- Deposit cost
- Taxes
- Retirement timing
- Military retirement tradeoffs
