How the numbers are calculated
  • Fuel use comes from EPA city and highway ratings, weighted by your city/highway split (the distance-weighted harmonic mean, as EPA does).
  • Electricity use uses EPA's kWh per 100 miles, which is measured at the wall and includes charging losses. Your charging cost blends home and public rates by your home-charging share.
  • Plug-in hybrids split miles between electricity and gas using EPA's utility factor, which assumes you charge daily. Change it on the car's card if you charge more or less.
  • Maintenance uses Argonne National Laboratory's lifetime-average scheduled-maintenance cost per mile for each powertrain. Edit it on each car's card.
  • Financing: for a car you pay for monthly, the monthly payment comes from the standard loan formula using your down payment, term and APR. If you enter the payment you were quoted instead, the page works out the APR it implies. Net cost adds only the interest you actually pay while you own the car; the principal is already in the price. If you sell before the loan ends, the remaining balance is settled from the sale.
  • Net cost = purchase price after incentives + loan interest + fuel or charging + maintenance + other yearly costs − resale value.
  • Break-even is when the pricier car's lower running costs have paid back the difference in upfront price and any extra interest.
  • Not included unless you enter them: insurance, registration, taxes and fees, repairs, home charger installation and loan fees. Add them using "Other yearly costs" and "Incentives". Depreciation is covered by "Resale value".
