Why Bogleheads & FIRE Planners Upgrade from cFIREsim & FIRECalc to NovaPlanner
Legacy calculators like FIRECalc, cFIREsim, and FICalc are great for testing post-retirement withdrawal rates on an already-retired portfolio. However, they struggle when you are still accumulating wealth, planning a career downshift (Coast FIRE / Barista FIRE), paying off a mortgage, or timing when your Safe Passive Income crosses your living expenses.
NovaPlanner Interactive Planner Studio combines full-lifecycle cashflow accumulation with retirement drawdown, 1,000-iteration Monte Carlo confidence cones, Guyton-Klinger guardrails, and historical market crash cohorts (1929 Great Depression, 1966 Stagflation, 2000 Dot-Com, 2008 GFC) on an interactive 60fps canvas—with 1-click stateless URL sharing (?plan=...) for Bogleheads and forum plan reviews.
