Our automotive calculators help you plan a car purchase or lease and understand what a vehicle really costs to run. Work out what car your income supports, estimate a payment or lease, compare EV charging costs and real-world range, check trip fuel costs and your true gas mileage, and compare tire sizes — every tool free, with the formula shown.
Buying & Leasing
The car affordability calculator works backwards from your income using the 20/4/10 rule, the car payment calculator factors in down payment, trade-in, and tax, and the auto lease calculator breaks a lease into depreciation and finance charges.
Running Costs
The fuel cost calculator estimates the gas for any trip, and the gas mileage calculator shows your real MPG, L/100km, and km/L.
Tires & Fit
The tire size calculator converts sizes to overall diameter and compares two tires for fit and speedometer effect.
