Car Calculators
Tools for the running costs of a car, starting with the fuel cost of a trip.
Fuel Cost Calculator
How much will you spend on fuel for a trip? The sum is simple: the litres are the distance divided by 100, times the consumption (l/100 km), and the cost is those litres times the price per litre. For example, 100 km in a car that does 6 l/100 km, with fuel at €1.80 per litre, costs €10.80. Enter the distance, your car’s average consumption and the current fuel price, and the calculator shows the litres needed, the total cost, the cost per kilometre and, if you share the car, the cost per person. You can count the trip one way or there and back.
Open calculator →Car Leasing Calculator (Portugal)
How much is the monthly rent on a car leasing? This calculator estimates the rent from the vehicle value, the initial down payment, the nominal annual rate (TAN), the term and the residual value (the buy-out at the end). Because leasing is a rental with an option to buy, it shows two totals: what you pay if you keep the car at the end and what you pay if you hand it back. The figures are shown without VAT.
Open calculator →Speeding Fine Calculator (Portugal)
Flashed by a radar in Portugal and wondering what it will cost? Enter your speed, the local limit, whether it happened inside or outside a locality and the vehicle type: the calculator applies the article 27.º table of the Código da Estrada and shows the fine, the offence classification, the licence points you lose and the driving ban you risk.

About car calculators
Owning and using a car has several costs: the fuel for each trip, the annual tax, financing the purchase and maintenance. These calculators help you estimate those costs from values you enter, starting with the fuel cost of a trip (distance, consumption and price). They link to the IUC and car-loan calculators so you can see the full picture. They are educational estimates that do not replace professional advice. Each calculator explains the sum it does and links to the article that goes deeper.
