Frequently asked questions
Fuel only: road-trip totals, monthly commute costs, splitting a trip with friends, and comparing two vehicles on the same distance. It does not include tolls, parking, depreciation, insurance, or maintenance — those are ownership costs, not fuel costs, and they stay out on purpose so the fuel number can be checked against a pump receipt.
From you. This calculator has no live gas prices — you enter the price you pay at your station, and every example value on the page is labelled as an example. If your trip crosses states with very different prices, run it once per state price and add the two totals.
Charging cost only: monthly cost from your state's average residential electricity rate (EIA, August 2026), blended across your home and fast-charging mix, plus a per-mile comparison against gas. It does not include the charger, installation, or any buying advice — and if your plan's rate differs from the state average, you can enter your own rate.
Price per gallon divided by miles per gallon. At $3.50 a gallon and 25 mpg, that is $0.14 per mile. It is the most useful single number for comparing vehicles or prices, because it scales to any distance without redoing the whole trip.
