Fuel Cost Calculator
Calculate trip fuel costs with options for round trips, split costs among passengers, and route comparisons. Supports MPG and L/100km.
About
Accurately budgeting for vehicular travel requires more than a simple multiplication of distance and price. Fuel efficiency varies by speed and terrain, and costs scale linearly with distance. This tool is designed for logistical planning, allowing users to estimate total financial outlay for single or return journeys.
It specifically accommodates group travel scenarios via the "Split Cost" function and supports global unit standards (Imperial MPG vs. Metric L/100km). It is particularly useful for comparing the economic efficiency of different routes (e.g., a shorter but slower city route vs. a longer highway route).
Formulas
The cost derivation depends on the efficiency unit system.
Where d is distance, P is price per unit, and L is Liters/100km.
