Cost Breakdown
Calculation: 0.0 km ÷ 100 × 0.0 L/100km = 0.0 L
Cost: 0.0 L × $0.000/L = $0.00
Trip Cost Analysis
Example Calculation
Weekend Road Trip
Distance: 295 km (183 miles)
Car fuel economy: 8 L/100km (29.4 MPG US)
Fuel price: $1.60 per liter
Number of people: 4
Calculation Steps
1. Fuel needed: 295 km ÷ 100 × 8 L/100km = 23.6 L
2. Total cost: 23.6 L × $1.60/L = $37.76
3. Cost per person: $37.76 ÷ 4 = $9.44
Result: $37.76 total, $9.44 per person

Understanding Gas Calculations
How to Calculate Fuel Usage
Our gas calculator uses a simple but accurate formula to determine how much fuel you'll need for your trip. The basic principle is to multiply your distance by your car's fuel consumption rate.
Why Split Gas Costs?
- •Makes travel more affordable for everyone
- •Encourages carpooling and reduces emissions
- •Fair way to share travel expenses
- •Helps plan group trip budgets
Calculation Formula
Step 1: Calculate Fuel Needed
Fuel = (Distance ÷ 100) × Fuel Consumption (L/100km)
Step 2: Calculate Total Cost
Total Cost = Fuel Needed × Price per Liter
Step 3: Split Among People
Cost per Person = Total Cost ÷ Number of People
