Automotive Calculators
25 calculators
Running costs and performance for a car: depreciation, lease and insurance estimates, fuel spend, brake and tyre wear, and acceleration figures. Quoted performance assumes a stock vehicle in good condition on a level surface; real numbers move with load, tyres, temperature and altitude. Cost estimates are regional averages, not a quote.
- 0-60 mph Calculator Estimate 0–60 mph time, quarter-mile elapsed time and trap speed from engine horsepower and vehicle weight.
- Brake Pad Life Calculator Estimate modeled brake pad life from an entered mileage assumption; this is not a wear inspection or replacement date.
- Car Depreciation Calculator See how much value a car loses each year and what it will be worth in the future.
- Car Insurance Scenario Calculator — Illustrative Premium Enter a base premium in USD and explore fixed assumptions for driver age, record, mileage, vehicle value and deductible. Illustrative budget, not an insurer quote.
- Car Lease Calculator Calculate a monthly lease payment from the vehicle price, residual value and money factor.
- Car Lease vs Buy Calculator Compare the total cost of leasing a car against buying it and keeping it for the same period.
- Car Loan Calculator Calculate the monthly payment, total interest and total cost of a car loan.
- Car Loan Payoff Calculator Find the remaining balance, the time left and how much extra payments would save.
- Car Payment Calculator Find the monthly car payment for a given loan amount, interest rate and term.
- Car Trade-In Value Calculator Estimate what a dealer is likely to offer for your car as a trade-in.
- Car Wrap Cost Calculator Estimate the material and labour cost of wrapping a vehicle.
- Carpooling Savings Calculator See how much each person saves by carpooling instead of driving alone.
- Compression Ratio Calculator Calculate an engine compression ratio from swept volume and clearance volume.
- Engine RPM Calculator Calculate engine rpm from road speed, gearing and tire size.
- EV Charging Cost Calculator Estimate EV charging energy and cost from battery capacity, your charging-efficiency estimate, vehicle efficiency, electricity rate and fees.
- Fuel Cost Calculator Calculate the fuel cost of a trip from the distance, your fuel economy and the price of fuel.
- Gas Mileage Calculator Calculate fuel economy in mpg and litres per 100 km from distance and fuel used.
- Gear Ratio Calculator Estimate theoretical road speed from engine RPM, gear ratio, final drive and tire diameter. Actual speed can differ because of tire rolling radius, drivetrain behavior and other conditions.
- Horsepower Calculator Calculate engine horsepower from torque and rpm, and estimate quarter-mile performance.
- Oil Change Interval Calculator Estimate remaining mileage from your vehicle’s maintenance interval and miles since the last oil change.
- Road Trip Fuel Planner Plan fuel stops and the total fuel cost for a long drive.
- Tesla Charging Cost Calculator Estimate the cost of charging a Tesla at home versus a Supercharger.
- Tire Size Calculator Compare two tire sizes and see the effect on diameter, speedometer reading and ground clearance.
- Towing Capacity Calculator Estimate trailer limits from vehicle payload and entered ratings. Compare the result with your vehicle, trailer and hitch specifications before towing.
- Wheel Offset Calculator Compare theoretical wheel positions from width and offset; confirm real vehicle clearances before fitting.

Vehicle ownership questions combine several different models. Fuel consumption is a measured rate, a payment depends on financing terms, and a tire or drivetrain calculation describes dimensions or ratios. Select the calculation that matches your question rather than comparing outputs with different meanings.
Compare running and purchase costs
Use fuel cost for a distance-and-price scenario, charging cost for electricity inputs, and the loan or lease tools for financing assumptions. Depreciation is a separate estimate and does not determine a vehicle’s sale price.
Inspect dimensions and mechanical relationships
Tire size and wheel offset describe geometry, while engine RPM and gear ratio connect rotational quantities. An estimate of acceleration or horsepower depends on a different model and should not be read as a measured test result.
Use actual ratings for vehicle decisions
Check the vehicle and component manufacturer’s specifications for fitment, maintenance and capacity. A simplified calculation cannot certify safe towing, braking, tire clearance or a mechanical modification.
