Automotive
A vehicle costs more than its purchase price. The automotive calculators split ownership into the questions people actually ask: what a lease or loan costs each month, how much fuel the car burns, how quickly it loses value, and how its power compares with another model.
Used together, they let you compare two cars or two financing offers on running cost instead of sticker price alone.

Which automotive calculator do you need?
Estimate monthly lease payments and understand which part of the payment comes from the car's value and which from financing.
Project resale value and total depreciation across the years you plan to keep the car.
Budget fuel for a specific trip or for a year of driving, including the fuel price you pay.
Convert between efficiency figures, or work out fuel consumption and cost per distance.
Compare engine output between horsepower and kilowatts.
Lease, loan or keep
A lease payment is driven by the capitalized cost, the residual value and the finance charge, so two cars with the same sticker price can lease very differently. Depreciation is usually the largest single ownership cost, and it is also what makes a lease payment smaller or larger.
Compare options over the same holding period: purchase price minus resale value, plus financing, fuel, insurance and maintenance. The monthly payment alone hides the total.
Reading fuel and power figures
Fuel consumption depends on the driving mix, load and conditions, so published efficiency figures are comparisons rather than promises. Cost per distance is often more useful than litres or gallons per 100 units, because it folds in the price you actually pay.
Power and torque are different quantities: horsepower describes the rate of doing work, while torque describes rotational force. Converting between hp and kW is a straightforward unit change and says nothing about the car's behaviour.
What the numbers exclude
- Dealer fees, taxes, insurance, maintenance and incentives are not included unless you enter them.
- Depreciation depends on model, mileage, condition and market — a projection is not a valuation.
- Fuel-cost figures use the price you enter, not live pump prices, and assume the consumption you specify.
