About

Flexible Retirement Planner uses Monte Carlo simulation to model retirement outcomes and report a probability of success. It runs 10,000 simulated paths through both savings accumulation and spending phases. Users can choose Stable, Flexible, or Conservative spending policies, run sensitivity analysis to see which inputs have the most impact, and manage multiple what-if scenarios in the standalone version. The planner supports income and savings growth projections, withdrawal planning, detailed tax modeling, and Social Security modeling. Its standalone application runs offline, with downloads for Windows and for Mac/Linux; the Windows version does not require Java. Personal use is 0.00 USD per free for individuals using it non-commercially, 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. The license agreement cautions that the website may not always be available, secure, or private, and does not guarantee uninterrupted or error-free use.
