All you have to do is factor in your current assets, your future savings rate, how much those assets will grow in value based on your investment decisions, over your uncertain life expectancy, and how much they will be devalued by inflation.

But there is a sophisticated computer you're modeling process that is designed to deal with all these variables. It is called Monte Carlo modeling.

Despite the name, Monte Carlo modeling has nothing to do with gambling. It's simply the statistical science of modeling multiple alternatives to come up with a likely range of probable results. Monte Carlo was a code name for a technique employed during the Manhattan Project to create the atomic bomb. Now it is being used to describe this simulation process, which has been made easier, faster, and more accessible by today's computers.
