RetireStudio is a 100% free interactive wealth, tax, and retirement simulator—built as an open, zero-paywall alternative to ProjectionLab ($109/yr) and Boldin ($144/yr). Model multi-bucket assets, drag life milestones directly on your wealth curve, stress-test against 1,000 Monte Carlo market paths and historical crashes, and spin the interactive 3D Readiness Earth to compare retiring across 22 global expat hubs. Save scenarios locally or to the cloud for $0.
