safewithdrawal.com helps you estimate both when you can safely retire, and how much money you can expect to have after a given number of years. You can easily compare multiple scenarios, which can be useful to quantify how small changes today can translate into big changes in your future retirement prospects. The name "safewithdrawal" comes from the term "Safe Withdrawal Rate", which is defined as the percentage of your assets you can safely withdraw each year in retirement without running out of money. One of the most influential works in this area was the 1998 Trinity study, which is the origin of "The 4% Rule". Research in this area has continued to evolve, and safewithdrawal.com allows you to model any assumed safe withdrawal rate, 4% of otherwise.
