Free Car & Fuel Calculators
Free car, towing and EV calculators: fuel cost, MPG, trip cost, truck payload, trailer weight distribution and EV charging time & cost. No sign-up, instant results.
Fuel Cost Calculator
Work out what any vehicle costs to fuel per year, month and mile from its MPG, your annual mileage and local fuel price.
MPG Calculator
Calculate your real-world fuel economy from trip miles and gallons filled, and see how far it sits from the EPA rating.
Trip Cost Calculator
Estimate the fuel cost of a specific drive from distance, fuel economy and gas price, split per person and round trip.
Payload Calculator
Find your remaining payload capacity from GVWR and curb weight, then subtract passengers, cargo and tongue weight to see if you're over the limit.
Trailer Weight Distribution Calculator
Check whether your tongue weight sits in the safe 10-15% (conventional) or 15-25% (fifth wheel) range, and see remaining tow rating headroom.
EV Charging Calculator
Estimate EV charging time and cost from battery size, charge percentage, charger power and electricity price, plus savings vs a gas car.
Gas vs EV Cost Calculator
Compare the true cost of owning a gas car versus an EV: purchase price, incentives, fuel or electricity, maintenance, insurance and resale value over your ownership period.
