Automotive Calculators
Tire sizes, fuel and trip costs.
Tire Size
Compare two tire sizes (like 205/55R16 vs 225/45R17): see the overall diameter in inches, the percentage difference and how far your speedometer will read off.
CalculateAutomotiveGas Mileage
Work out your car’s gas mileage in MPG from the miles driven and gallons used, plus the cost per mile and the metric equivalents (km/L and L/100km).
CalculateAutomotiveGas Trip Cost
Estimate what a road trip will cost in gas: fuel from the distance and your car’s MPG, plus tolls, with an option for a round trip and splitting the cost between passengers.
CalculateAutomotiveCost Per Mile
Find the real cost of every mile you drive: fuel plus your fixed costs (insurance, registration, maintenance) spread over the miles you drive each year.
CalculateAutomotiveEV Range
Estimate an electric car’s range from the battery size and efficiency in miles per kWh, plus the cost of a full charge and the cost per mile at your electricity rate.
CalculateAutomotiveCar Depreciation
Estimate how much your car will be worth in the years ahead from its yearly depreciation rate. See the projected value, the total loss and the value curve year by year.
CalculateAutomotiveFreight Cost
Price a haul by the mile: fuel cost plus a per-mile rate that covers wear, fixed costs and your margin, with an option for a round trip.
CalculateAutomotiveMaintenance Schedule
Find the mileage of your car’s next service and roughly how many months away it is, based on your monthly driving average.
