Best FIRE Planning Tools 2026: Honest Rankings by Use Case
Every major FIRE planning tool, ranked by which user each is best for. This is our roundup — EnoughMoney's opinion, but we include our own biases openly and have no affiliate relationships with any tool listed.
TL;DR
Most serious FIRE planners use 2-3 tools together. A reasonable stack: EnoughMoney for tax + city planning, ProjectionLab or Boldin for primary US modeling, FIRECalc or cFIREsim as a historical-data sanity check. Empower is useful for aggregation (not planning).
