Civilian vs. Federal vs. Military: How the TSP Stacks Up
A side-by-side look at what each career path puts toward your retirement — the pension, the agency/employer match, and the nest egg it builds. Built for anyone weighing a military, federal civilian, or private-sector career.
Compare the three packages
Enter a few numbers. We’ll estimate each path’s pension, what the employer adds to your TSP/401(k), and the account it grows into.

“Total package value” adds the projected TSP/401(k) balance to the savings equivalent of the pension — the nest egg you’d need (at a 4% withdrawal rate) to replicate that lifelong, inflation-adjusted check. Flat salary, contributions invested annually; estimates only.
Why the gap is so large
Two things set federal and military careers apart from most private-sector jobs: a defined-benefit pension that pays for life and rises with inflation, and an agency match worth up to 5% of pay on top of your own savings. A typical private employer offers neither a pension nor as generous a match.
| Feature | Military (BRS) | Federal civilian (FERS) | Private 401(k) |
|---|
| Pension multiplier | 2.0% × years × High-3 | 1.0% (1.1% at 62+ & 20 yrs) × years × High-3 | None |
| Pension inflation (COLA) | Yes | Yes | — |
| Automatic contribution | 1% of pay | 1% of pay | Usually none |
| Match | Up to 4% more (5% total) | Up to 4% more (5% total) | Varies; often ~3% |
| Retirement account | TSP (low fees) | TSP (low fees) | 401(k) (fees vary) |
| Portability if you leave early | TSP is yours; pension needs 20 yrs | TSP is yours; pension vests at 5 yrs | 401(k) is yours; match may vest over years |
How the government match works (BRS & FERS)
Both systems add an automatic 1% of your pay to the TSP whether or not you contribute. Then they match your contributions: dollar-for-dollar on the first 3%, and 50 cents on the dollar for the next 2%. Contribute 5% and the government adds the full 5% — an instant, guaranteed return before any market growth.
Why a pension is worth more than it looks
A pension is a paycheck for life that keeps pace with inflation. To replicate, say, a $20,000/year pension from savings alone, you’d need roughly $500,000 invested (using the 4% rule) — and you’d carry the market risk yourself. That’s the “savings equivalent” the tool above shows.
Deciding between the private sector, federal service, or a career in the military? Here’s why this comparison matters to you: the government match is free money from day one, the TSP charges among the lowest fees anywhere, and the pension is a guaranteed, inflation-protected income stream most private-sector jobs simply don’t offer. Over a full career, the federal or military package can be worth hundreds of thousands of dollars more than a comparable private job — so it’s worth weighing carefully before you choose.
The honest caveats
- The military (BRS) pension generally requires 20 years of service; FERS vests in 5 years. Leave earlier and you keep your TSP but not a full pension.
- Private-sector pay can be higher up front, and a strong 401(k) match or equity can narrow the gap — adjust the inputs to model a specific offer.
- This tool is educational and simplified (flat salary, level contributions, one average return). It is not financial advice.
