Monte Carlo Simulation

10,000 battery degradation and cost scenarios using DOE/Geotab data calibrated to your vehicle and climate.

Monte Carlo Simulation

Rather than a single point estimate, Celvari runs 10,000 simulated ownership scenarios for each vehicle comparison. Battery degradation draws from DOE/Argonne research and the Geotab 22,700-vehicle dataset, using log-normal fade curves adjusted by climate zone and DCFC charging frequency.

The simulation produces a complete cost distribution:

  • Expected (mean) cost difference -- average across all scenarios
  • Break-even year -- the median year EV total cost drops below ICE
  • 95th percentile cost -- worst-case planning number
  • Full histogram -- see the entire distribution of possible outcomes

This lets you choose based on your risk tolerance: a conservative buyer might focus on worst-case cost, while an aggressive optimizer focuses on expected savings.
