how much will my tsp grow after retirement

Your TSP can keep growing after retirement if it stays invested, but the amount depends on your balance, withdrawals, fund mix, fees, and market returns. A rough example from a public calculator discussion shows that $300,000$300,000$300,000 growing at 10% a year with no contributions could reach $500,000$500,000$500,000 in about 5.36 years, but real retirement growth is usually slower because you are also drawing money out.

What drives growth

  • Investment returns: Higher stock exposure can mean more growth, but also more volatility.
  • Withdrawals: Taking money out reduces how much remains invested.
  • Fees and taxes: These can lower net growth over time.
  • Inflation: Even if the balance rises, buying power may not rise as fast.

Simple way to estimate it

You can think of post-retirement TSP growth like this:

  • Start with your current balance.
  • Subtract expected yearly withdrawals.
  • Apply an assumed annual return to what remains.

For example, if your account earns 6% but you withdraw 4%, the net growth is very different from a no-withdrawal scenario. A TSP growth calculator can model this more realistically than a simple rule of thumb.

Practical range

A cautious planning range many retirees use is:

  • Conservative: 3% to 4% annual return.
  • Moderate: 5% to 6%.
  • Aggressive: 7%+ with higher market risk.

That means your TSP might grow a little, stay roughly flat, or decline over time depending on how much you withdraw. The key question is whether your withdrawal rate is lower than your long-run return after fees and inflation.

Example

If you retire with $400,000$400,000$400,000:

  • At 5% growth, it may rise to about $420,000$420,000$420,000 after one year before withdrawals.
  • If you withdraw $20,000$20,000$20,000 that year, the ending balance could be much lower.
  • Over several years, the compounding effect becomes very sensitive to withdrawal size.

Best next step

The most accurate answer comes from your own numbers: current TSP balance, expected withdrawals, and fund allocation. I can estimate your TSP growth after retirement with a simple projection if you share those numbers.
