In their own words
Flexible Retirement Planner
Flexible Retirement Planner models retirement outcomes with Monte Carlo simulation and reports the probability that a plan succeeds. It runs 10,000 simulated paths spanning savings accumulation and retirement spending. Users can compare Stable, Flexible, and Conservative spending policies, test different assumptions, and use sensitivity analysis to see which inputs affect results most. The standalone version lets users save inputs and maintain multiple what-if scenarios, and it works offline. The planner includes income and savings growth projections, withdrawal planning, detailed tax modeling, and Social Security modeling. Standalone downloads are provided for Windows and Mac/Linux; the Windows version does not require Java. The planner is free for individual non-commercial use, and educators and trainers may use it for educational purposes. A voluntary contribution of any amount unlocks a personal-use license key. Commercial use, including by financial planners, is not authorized or supported. Its maker, Random Walk Ventures LLC, created it in 2006.
