Fuel Savings Calculator
Find out how much you save by driving less — weekly, monthly and yearly.
What is a fuel savings calculator?
A fuel savings calculator estimates how much money you save by reducing your driving distance. Whether you are switching to remote work, carpooling, moving closer to your office, or considering an electric vehicle, this tool quantifies the financial impact. Even small reductions in daily driving can add up to significant annual savings.
The calculator works by converting your distance savings into fuel volume using your vehicle's consumption rate, then multiplying by the fuel price. It supports both conventional fuel vehicles (petrol/diesel measured in liters or gallons) and electric vehicles (measured in kWh).
How fuel savings are calculated
The formula is straightforward: distance saved multiplied by fuel consumption rate, multiplied by fuel price. For example, saving 20 km per week in a car that uses 0.6 liters per 10 km at $1.80 per liter: 20 km multiplied by 0.06 L/km = 1.2 liters, times $1.80 = $2.16 saved per week, or about $112 per year.
How to use this tool
Enter the distance you save (per day or per week), your vehicle's fuel consumption rate, and the current fuel price. For electric vehicles, select the EV option to switch to kWh-based calculations. The calculator shows weekly, monthly, and annual savings.
Electric vehicle calculations
For EVs, the consumption rate is measured in kWh per 10 km — typically 1.5 to 2.5 kWh for modern electric cars. Enter your electricity rate per kWh instead of a fuel price. EVs are generally 3–4 times more energy-efficient than petrol cars, which is one reason why switching to an EV can dramatically reduce transportation costs even if the purchase price is higher.
Ways to reduce fuel costs
Beyond driving less, you can reduce fuel consumption by maintaining proper tire pressure (under-inflated tires increase consumption by 3–5%), removing unnecessary weight from your vehicle, avoiding aggressive acceleration and braking, using cruise control on highways, and combining multiple errands into one trip to reduce cold starts.
Frequently asked questions
How much does the average person spend on fuel per year?
This varies enormously by country, driving distance, and vehicle efficiency. In the United States, the average household spends approximately $2,000–3,000 per year on gasoline. In Europe, where fuel prices are higher but distances are shorter, annual fuel costs are comparable. EV owners typically spend 50–70% less on energy than petrol car owners.
Is it worth switching to an electric vehicle for fuel savings alone?
It depends on your driving distance and local electricity prices. If you drive over 15,000 km per year, the fuel savings often offset the higher purchase price within 5–7 years. High-mileage drivers (over 30,000 km/year) can save enough on fuel to make the EV cheaper overall within 3–4 years. Use the calculator to model your specific situation.
