How this works
Return is a constant assumption, not a forecast. We convert it to a real monthly rate, apply growth, then withdraw at the end of each month. Spending stays constant in today’s dollars. This omits market volatility, changing income, large one-off expenses and sequence risk. Try lower returns and higher spending as well.
The starting year comes from the current calendar year. Your age at the milestone is current age plus elapsed calendar years; birthdays within the year are not modeled. A chosen research milestone date does not predict when a treatment will exist, work or become accessible. There is no survival probability or intervention-tier recommendation.
General education, not medical or financial advice. Results depend on the supplied assumptions and do not guarantee outcomes.
