Thrift Savings Plan"Am I behind?" is one of the most common questions federal employees ask about their TSP. Averages can give you a rough yardstick — but they are also a little misleading, and they matter far less than the trajectory you are on.
Averages rise steeply with age and tenure, but they are skewed by high savers, so the typical balance is lower than the average. What actually decides your outcome is your contribution rate, your allocation, and time — not how you compare to a headline number.
What the published data actually shows
The Federal Retirement Thrift Investment Board publishes plan-wide participation and balance statistics every month in its Participant Activity Report, but it does not publish a public age-banded table of TSP balances. The by-age figures that circulate online are third-party estimates rather than published data, so none appear here — the current plan-wide averages are in the FRTIB Participant Activity Report at frtib.gov.
Two things are worth knowing about any average you do find. Averages are pulled upward by a minority of very large accounts, so the typical balance sits well below the average. And for federal employees, years of service is usually a better reference point than age — someone who joined the government at 40 will not resemble a same-age colleague who joined at 22.
Plan-wide figures, not age-specific. Balances vary widely by salary, tenure, contribution rate, and market timing.
Why the average is not the whole story
Averages are pulled upward by a minority of very high savers, so most people sit below the average. A more honest question than "am I average?" is "given what I have now, where am I heading?" That you can actually answer.
Project your own number
Your ending balance is driven by three things you largely control: how much you contribute, how you are allocated, and how long you stay invested. Set your balance and life stage below to see a projection — and how a disciplined mix compares:
Falling behind? The fastest levers
- Capture the full match. Contributing enough to receive every dollar of agency match is widely described as the highest-return step available within the plan.
- Fix the allocation. Sitting too heavily in the G fund for decades is the quiet reason many balances lag. See allocation by age.
- Give it time. Compounding does the heavy lifting in the final decade — which is exactly why bailing out at the wrong moment is so costly.

The part that actually matters: discipline
A sound allocation only helps if you hold it through the uncomfortable moments and adjust it for the right reasons. That is the idea behind the TSP Edge strategy — a rules-based monthly update that tells you when a change is warranted, so your TSP follows evidence instead of emotion. Most months, it says do nothing, which is usually the hardest and most correct answer.
