Measure cash cost with matching periods
Vehicle cost per mile adds energy, maintenance, insurance, depreciation, financing, and other cash categories over one stated period.
Use annual miles with annual costs or monthly miles with monthly costs.
Compare EV and gas from your actual prices
EIA defaults are a reference snapshot; state selection and the latest verified observation period are shown, while a user-edited price is preserved. Charging access and efficiency can change the result.
EV vs. gas calculator reports the scenario winner and break-even rather than assuming EV is cheaper.
Keep the tax method separate
Standard vs. actual mileage compares tax arithmetic. Lease vs. buy compares contract economics.
Use current IRS guidance for eligibility, records, depreciation, lease treatment, and any loan-interest rule.
Frequently asked questions
Does standard mileage reimburse my gas?
No. It is a tax deduction representation, not a cash reimbursement.
Can I use EIA price as my actual cost?
It is a default reference; edit it to your documented price when appropriate.
Should I add depreciation to mileage?
Do not stack core vehicle methods for the same period without confirming the applicable rule.
