About FIRE HealthCalc

FIRE HealthCalc is a free tool designed to help individuals navigate the ambiguity of US healthcare cost planning in FIRE. Unlike many other expenses, healthcare costs can change significantly as one ages and there are complex interactions between ACA rules, tax planning and income that guide subsidies. This calculator helps you:

  • Model healthcare costs for your household across different income scenarios
  • Optimize withdrawal strategies to fund required income without blowing up ACA subsidies
  • Get your liftetime healthcare expenses FI number

The tool uses 2026 ACA marketplace rules, Medicare cost structures, and federal poverty level (FPL) guidelines to estimate healthcare costs. It models how different withdrawal strategies from pre-tax, taxable, and tax-free accounts affect your MAGI and, consequently, your eligibility for subsidies and surcharges.
