FIRE Scenarios & Projections

Data sources & methodology: FIRE number = annual expenses ÷ withdrawal rate. Years to FIRE computed by projecting portfolio growth at stated real return until it exceeds the FIRE number. State Pension reduces the FIRE number by capitalizing that annual income. Based on the Trinity Study (Bengen 1994) and subsequent research. Past market returns do not guarantee future results.
