What Could Your TSP Become?

Your Thrift Savings Plan is one of the most powerful retirement tools in America — rock-bottom fees, an agency match that's literally free money, and decades of compound growth working for you. Plug in your numbers and see what steady contributions could become by the time you retire. It's an estimate to help you plan, not a promise of future returns.

Rough numbers are fine — you can adjust and re-run as many times as you like.

Your Projection

Projected TSP Balance at Age

Assumes annual compounding, contributions added each year, and your salary growing steadily.

• Try increasing your contribution by just 1% each year — you'll barely feel it in your paycheck, but your future self will.
• Don't try to time the market with interfund transfers. Missing just a handful of the market's best days can cost you years of growth.
• Review your fund mix as you get closer to retirement — the right allocation at 40 usually isn't the right one at 60.

These figures are estimates for education only, not investment advice. Actual returns vary, and past performance doesn't guarantee future results.
