Advanced FIRE Calculator

The Advanced FIRE Calculator is designed for users who need a deeper retirement drawdown model instead of a single accumulation estimate. It focuses on sequencing across account types, tax-aware withdrawal behavior, and long-horizon sustainability under changing assumptions. This page is best used after you have a baseline FIRE timeline, because the advanced model is strongest when you are comparing two or three explicit strategy variants rather than exploring from scratch. Evaluate how account order, withdrawal rates, and inflation assumptions change projected durability. The practical objective is to identify where your plan is robust, where it is fragile, and which adjustments improve the probability of a stable retirement income path without overfitting to one market scenario. Stress-test tax-aware withdrawal sequencing, inflation assumptions, and longevity risk with detailed retirement drawdown modeling. Review assumptions before acting and compare more than one scenario to reduce planning risk.
