Modern Retirement Identities: The FIRE Framework
Modern Retirement Identities: The FIRE Framework FIRE (Financial Independence, Retire Early) is built on the “4% Rule” and “25x annual expenses” framework from the US Trinity Study — essentially the same corpus-multiplier math used in traditional retirement planning (Topic 1), applied at an earlier age. This guide explains the major FIRE variants (LeanFIRE, FatFIRE, BaristaFIRE, CoastFIRE), and — importantly — why Indian FIRE aspirants need to adjust the original framework: higher general and healthcare inflation, the absence of an equivalent social safety net, and much longer retirement horizons all argue for a more conservative withdrawal rate (3–3.5% rather than 4%) and a larger explicit healthcare corpus. We also cover the “barbell” portfolio approach suited to early retirees, and the honest risks — sequence-of-returns risk, longevity risk, and the psychological transition covered in Topic 11.
