EV Battery Degradation & State of Health Calculator (SoH & Remaining kWh)
Estimate your electric vehicle's current Battery State of Health (SoH %), remaining usable capacity in kWh, and range retention based on vehicle age, odometer mileage, DC fast-charging habits, and climate.
Battery State of Health (SoH)
Calculator Inputs
Battery State of Health (SoH)
Remaining Usable Capacity (kWh)
Total Battery Degradation (%)
Lost Capacity
Usable Remaining Capacity vs Degraded Capacity (kWh)
Engineering estimation model synthesizing Geotab and Recurrent fleet data on lithium-ion calendar and cyclic aging.

We assume no liability for decisions made based on these estimates. Always verify with the relevant official authorities or a certified professional advisor.
Calculation Methodology
Total Degradation % = Calendar Aging + Cycle Aging (based on mileage) + Fast Charging Multiplier + Climate Factor. State of Health (SoH %) = 100% - Total Degradation. Usable kWh = Original kWh * (SoH / 100).
