How it Works
The formula is: (Total Distance / Vehicle Efficiency) * Fuel Price. For L/100km, the formula is (Distance / 100) * Efficiency * Price. The tool normalizes units to ensure mathematical accuracy regardless of the input system.
What is Trip Cost Calculator?
A logistics tool that estimates the total fuel expenditure for a journey. It accounts for vehicle efficiency (MPG or L/100km), trip distance, and current fuel prices to provide a budget-ready figure.
Step-by-Step Guide
- Set Distance – Enter total trip miles or kilometers (don't forget the return leg).
- Input Efficiency – Your car's average MPG or L/100km.
- Set Price – Current cost per gallon or liter.
- Calculate – View total cost.
Example
Input: 500 miles, 25 MPG, $3.50/gal
Result: $70.00
FAQ
Should I double for round trips?
Yes, unless you enter the total combined distance of both legs.
How do I account for traffic?
Traffic lowers efficiency. Reduce your MPG input by 10-15% for congested routes.
Does this include wear and tear?
No, this calculates fuel only. IRS mileage rates (e.g., 67 cents/mile) include wear/tear.
City vs Highway?
Use your highway MPG for long trips, or a combined average for mixed driving.
What about EV charging?
Enter your kWh/100km as efficiency and price per kWh to estimate EV costs.
Conclusion
Budgeting for fuel is often overlooked in travel planning. By calculating the exact cost, you can split expenses fairly among passengers or decide if flying might be cheaper. Always add a 10% buffer for traffic and detours.
