About This Calculator

This calculator is inspired by principles popularized by the FIRE (Financial Independence, Retire Early) movement. Notable contributors to these ideas include Mr. Money Mustache, among others. The core concepts, such as the importance of savings rate and the 4% rule, are widely discussed in personal finance literature.

Key concepts used in this calculator:

The 4% rule (25x annual expenses for retirement) is based on the Trinity Study (1998) by Cooley, Hubbard, and Walz.
The focus on savings rate as a key factor in achieving financial independence is a common theme in FIRE literature.

While inspired by these ideas, this calculator is our own implementation and should not be considered an official tool of any specific FIRE advocate or website.
