Monte Carlo simulator

Post by FBN2014 » Mon Jul 16, 2018 9:57 am

Does anyone know of a free Monte Carlo simulator where you can enter different portfolio allocations of various index funds or ETFs to see the probability of the portfolio lasting to various ages with varying withdrawal percentages?

For what you are describing, I believe this is a better source:

I like both Portfolio Visualizer (though its data only goes back to 1972 :() and FIRECalc (less flexible but much longer data series). Some like CFIRESIM as well, but I don't personally care for the interface.
