What changes this most?
Distance and real-world efficiency matter as much as pump price. Stress-test all three.
Sensitivity check
A roughly 10% move in annual distance changes the modeled headline result by up to $158 in this setup.
This is an energy-use estimate, not a fuel-price forecast.
Use the number fields, sliders, or a quick preset. You can fully clear a field while editing.
Formula
Annual fuel litres equal annual distance × litres per 100 km ÷ 100; fuel cost multiplies litres by price per litre.
All distance, efficiency and fuel-price inputs are user-entered. Real-world efficiency varies with route, weather, load and driving style.
Editable rates, growth assumptions, prices, fees, and percentages are planning inputs unless the calculator explicitly identifies a current source.
