About Simulix

See your financial future before it happens

Simulix brings institutional-grade Monte Carlo simulation to individual investors. Make informed decisions with data, not guesswork.

The Problem We Solve

Single-point projections are misleading

"If I invest $10,000 at 8% for 30 years, I'll have $100,627." This is how most financial planning works. One number. One outcome. But markets don't deliver steady 8% returns year after year.

In reality, you might see +22% one year, -15% the next, then +5%. The sequence of returns matters enormously, especially when you're adding or withdrawing money along the way.

Monte Carlo simulation runs thousands of different market scenarios to show you the full range of possible outcomes — not just the average case, but the best and worst cases too.
