Most federal retirement examples focus on higher GS levels.
But many employees spend a large portion of their career at GS-9 or similar pay grades.
So what does retirement actually look like at that level?
The Scenario
Assumptions:
- GS-9 Step 5 equivalent
- High-3 salary: $70,000
- Years of service: 30
- Retirement age: 57 (MRA)
- TSP balance: $250,000
- No military buyback
- No VA disability (baseline example)
FERS Pension
Formula:
High-3 × Years × Multiplier
$70,000 × 30 × 1% = $21,000/year
Monthly:
$1,750/month
FERS Supplement (Age 57–62)
Estimated Social Security at 62: $1,600/month
30 ÷ 40 = 0.75
0.75 × $1,600 = $1,200/month
TSP Income
Using a 4% withdrawal rate:
$250,000 × 4% = $10,000/year
Monthly:
$833/month
Total Income (Age 57–62)
- FERS: $1,750
- Supplement: $1,200
- TSP: $833
Total:
$3,783/month
At Age 62 (Supplement Ends)
- FERS: $1,750
- Social Security: $1,600
- TSP: $833
Total:
$4,183/month
What This Means
A GS-9 retirement:
- Is still stable
- Relies more heavily on Social Security
- Has less flexibility than higher GS levels
What If You Add VA Disability?
Example:
- VA: $1,200/month
New totals:
Age 57–62:
$4,983/month
Age 62+:
$5,383/month
This shows how impactful VA income can be.
What If TSP Is Lower?
If TSP = $150,000:
- Monthly income drops to ~$500
New total (57–62):
~$3,450/month
This is where planning becomes critical.
Key Challenges at GS-9
- Lower pension base
- Smaller TSP contributions over time
- Greater reliance on Social Security
- Less margin for error
5 Common Mistakes
- Assuming pension alone is enough
- Not contributing enough to TSP early
- Ignoring Social Security strategy
- Retiring too early without planning
- Not accounting for healthcare costs
Key Takeaway
A GS-9 retirement is absolutely achievable, but:
- It requires more careful planning
- Every income source matters more
- Small decisions have bigger impacts
