Methodology
We read Jan 2025 through May 2026 threads on Reddit, Bogleheads, Mr. Money Mustache forums, TrustRadius, G2, Capterra guides, Medium, X, blogs, and desks including Forbes Advisor, CNBC Select, Benzinga, NerdWallet, and Business Insider. Score equals each criterion rating times its weight, summed across five criteria. We overweight modeling depth because sequence, tax, and healthcare dominate FIRE outcomes more than chart polish. We discounted aggregation-only value unless it fed a credible planner and favored tools that surface assumptions clearly.
FAQ
Is ProjectionLab worth paying for if cFIREsim is free?
Pay for ProjectionLab when layered tax planning, partner-friendly visuals, and fast branching beat rebuilding spreadsheets. Stay on cFIREsim if withdrawal rules are your whole world and you refuse another subscription.
Why rank Empower below dedicated FIRE calculators?
Empower Personal Dashboard pairs linked balances with a usable Monte Carlo planner, yet tax and withdrawal nuance stay thinner than ProjectionLab or NewRetirement, and upsells grate on privacy-first DIY users.
Do FIRECalc and cFIREsim always agree?
No. Identical headline inputs can yield different success rates when inflation, fees, or withdrawal timing assumptions diverge, as forum threads document.
How often should I rerun these calculators?
After major life events, large allocation shifts, or tax-law changes that touch Roth or RMD plans.
Can I rely on a single calculator for lean FIRE?
No. Pair ProjectionLab or NewRetirement with cFIREsim or FIRECalc so silent modeling gaps surface before you quit work.
