Fuel Calculator

Fuel calculator 2026 online. Calculate the cost of a trip in seconds

This tool calculates the cost of a route based on the distance, average fuel consumption and fuel price. It supports five fuels: PB95, PB98, ON, ON Plus and LPG. Thanks to simple formulas, you get a result in four metrics: liters, total cost, cost per kilometer and cost per 100 km. The article contains a description of the algorithm, examples, step-by-step instructions, answers to frequently asked questions and good practices.

Why is it worth using a fuel calculator

Fuel calculator is a practical online tool that allows you to plan travel costs. Drivers often wonder how much their route to work, holiday trip or business trip will cost. Entering simple input data allows you to obtain precise information about your expenses in just a few seconds. Thanks to this, you can compare different driving scenarios, optimize fuel selection and predict the budget for the entire trip.

In the era of rising fuel prices and dynamic market conditions, the calculator becomes a tool that facilitates quick financial decision-making. Fleet drivers, private individuals and B2B entrepreneurs use it to control transport costs and plan their budget better.

What the calculator can do and who will benefit from it

The calculator takes distance in kilometers, average fuel consumption in liters per 100 km and fuel price. Calculates the total number of liters needed for the route, the total cost of the trip, the cost of one kilometer and the cost of a 100 km distance. The tool works universally for various vehicles - from small city cars, through SUVs, to delivery vehicles.

• Quick cost comparison for five types of fuel.
• Possibility to manually enter the current price per letter.
• Calculations presented in four indicators facilitate comparisons.
• Examples of ready-made calculations for typical routes.
• Simple operation based on the Livewire form.

Base fuel prices

The calculator uses predefined fuel prices. They are current at the time of implementation, but the user can change them at will. This ensures that calculations remain reliable regardless of market changes.

How we calculate - step-by-step algorithm

All calculations are based on simple mathematical formulas. The user provides data and the Livewire application calculates the result according to the component's logic.

// 1) Liters needed for the route
letters = (distance * consumption) / 100


// 2) Price used in the calculation
usedPrice = price entered by the user or base price


// 3) Total cost
cost_total = letters * usedPrice


// 4) Cost per kilometer
cost_per_km = usedPrice * (consumption / 100)


// 5) Cost of 100 km
cost_per_100 = usedPrice * consumption

Step-by-step instructions

1. Enter the distance in kilometers - e.g. 300.
2. Enter the average fuel consumption of the car - e.g. 7.5 l/100 km.
3. Select fuel type from the list.
4. Optionally, enter the price of fuel from your local station.
5. Click the Calculate button to get the r
