How Does the EV vs. ICE True Cost & Battery Depreciation Calculator Work?
When comparing electric vehicles (EV) and internal combustion engine (ICE) cars, basic calculations often fall short because they assume a one-size-fits-all model. To make a reliable choice, you need a tool that can translate local pricing and distance units dynamically. Our EV vs. ICE True Cost & Battery Depreciation Calculator is built specifically to bridge this gap, serving both European and American drivers.
This calculator features active unit selection, letting you switch distance variables from Kilometers (km) to Miles (mi) in real time. It also supports fuel consumption conversions between metric metrics (Liters per 100 km or km/L) and imperial standards (Miles per Gallon (US) or MPG (UK)). Additionally, the engine translates charging efficiency (kWh/100 km vs. Miles/kWh) to match your local charging standards.
Automotive acquisitions represent highly significant long-term capital investments. This calculator uses standardized mathematical models to simulate average battery degradation, charging efficiencies, and depreciation curves. However, real-world highway range, local electricity utility surcharges, actual fuel prices, and insurance premiums are subject to regional changes. By utilizing this program, you agree that you are solely responsible and liable for confirming these calculations with certified regional engineers, dealership quotes, and local utility billing policies before entering into any purchase or lease contract.
The Math / Formula Behind It
To perform an accurate side-by-side total cost of ownership (TCO) comparison, the calculator converts all metrics to standard base units internally before processing.
1. Direct Fuel and Energy Unit Standardizations
The internal engine standardizes fuel volume and distance variables. If you select MPG (US) for fuel consumption and per Gallon (US) for pricing, the program applies standard conversions to establish a uniform fuel usage cost:
Similarly, for electric charging metrics, the system scales input units to output true energy requirements per kilometer:
2. Modeling Battery Degradation and Resale Value
The program also factors in battery degradation, which directly affects the vehicle’s resale value over time. It models an average capacity loss of 10% for every 120,000 kilometers driven:
If the vehicle’s mileage is high enough that the estimated battery health drops below 85% by your target trade-in year, the system applies a sliding-scale penalty to the EV’s residual projection, keeping your analysis realistic.
Frequently Asked Questions (FAQs)
Why do EV and ICE depreciation curves differ so much?
Gas-powered vehicles depreciate on a relatively predictable curve driven by age, mileage, and wear on mechanical parts. EV depreciation, on the other hand, is heavily influenced by rapid battery technology developments and concerns over battery pack replacement costs. This is why our tool models a residual value penalty if the battery pack’s capacity drops significantly during your ownership term.
How does home charging affect the overall payback period?
Home charging is often significantly cheaper than public fast charging. Because of this, your charging ratio—the proportion of charging done at home versus public stations—plays a major role in your total cost of ownership. Maximizing cheap overnight home charging dramatically shortens your EV’s payback period compared to an ICE vehicle.
Is the battery health calculation accurate?
The battery degradation formula uses average real-world telemetry data (approximately 10% capacity loss per 120,000 km, or 75,000 miles). While actual degradation can vary depending on local temperatures, high fast-charging usage, and battery chemistry (e.g., LFP vs. NMC), this baseline provides a reliable, conservative estimate for long-term planning.
