TSP Monte Carlo Projection

Enter today's balances and see a range of simulated future outcomes, built by resampling real historical months across your held funds together — not one fund at a time. Assumes no future contributions or withdrawals.

Reading the chart: each simulation is one possible future built by resampling real historical months. The median (50th percentile) is the middle simulated outcome — half of the 2,000 simulations ended higher, half lower. The narrow band covers the middle 50% of outcomes (25th–75th percentile); the wide band covers the middle 80% (10th–90th percentile). Real results could still fall outside every band shown.

Disclaimer: This tool simulates 2,000 possible futures by resampling actual historical monthly returns since May 2003 — it is not a prediction. It does not model future contributions, withdrawals, taxes, or fees. Past performance does not guarantee future results.
