Is OnTrajectory good for FIRE?
Decent but not FIRE-optimized. It handles early retirement but doesn't specialize in FIRE-specific strategies (Roth ladder, 72(t) SEPP, Coast FIRE). EnoughMoney's strategy guides and calculators are more FIRE-focused.
Can OnTrajectory compare cities?
No. Cost of living is a single per-period expense input. EnoughMoney has 307 cities with detailed cost breakdowns.
