Blend gas and electric miles for true costs. Adjust prices, shares, and ownership years easily. See where money goes, then choose a better route.
Sample scenario to demonstrate expected output formatting.
| Scenario | Annual miles | EV share | Gas price | Electric price | Estimated cost / mile |
|---|---|---|---|---|---|
| Balanced commute | 12,000 | 35% | $3.60 | $0.16 | $0.53 |
| Mostly charging | 10,000 | 70% | $3.90 | $0.14 | $0.45 |
| Long trips | 18,000 | 15% | $3.40 | $0.18 | $0.58 |
Total miles: annual distance × ownership years (converted to miles internally).
Split miles: EV miles = total miles × EV share. Gas miles = total miles − EV miles.
Gas cost: gallons = gas miles ÷ MPG. Gasoline cost = gallons × gas price.
Electric cost: kWh-at-wheels = (EV miles ÷ 100) × kWh/100mi. Grid kWh = kWh-at-wheels ÷ charging efficiency. Electricity cost = grid kWh × electric price.
Vehicle cost (cash-flow): down payment + payments made − resale + remaining payoff.
Vehicle cost (simple): depreciation (purchase − resale) + interest paid during ownership.
Cost per mile: (sum of included categories) ÷ total miles.
It’s the percent of your total miles powered by electricity from the grid. If you rarely plug in, set it near zero. If you plug in daily, raise it to match your typical driving pattern.
Some energy is lost as heat during charging. Charging efficiency converts “energy used by the car” into “energy bought from the grid,” which makes electricity cost estimates more realistic.
Cash-flow net works well when you may sell before the loan ends. Depreciation + interest is simpler for quick comparisons. Try both to see how financing timing changes results.
If you want an all-in ownership cost per mile, include them. If you only want energy cost per mile, uncheck those categories. The breakdown helps you compare either view.
Use it for tires, oil changes, brakes, and small repairs. If you already know your yearly maintenance, you can keep per-mile low or zero and rely on the per-year field.
Yes. Pick kilometers as your input unit. The calculator still computes using miles internally, then shows both per-mile and per-kilometer results for easier comparisons.
If your charging cost is effectively zero, set the electric price to 0.00. You can still keep charging efficiency if you want energy-use estimates without cost.
No. They’re estimates based on your inputs. Real costs depend on driving style, weather, tire pressure, local prices, and unexpected repairs. Update inputs as conditions change.
