📌 What is Gas Expense?

Gas expense is the total amount you spend on fuel to operate your vehicle over a specific distance. It depends on:

• 🚗 Vehicle mileage (fuel efficiency)
• 🛣️ Total distance traveled
• 💰 Current fuel price per liter/gallon
• 🔁 Frequency of the trip (one-way, round-trip, daily)

Understanding your gas expenses helps you:

• ✅ Budget better for travel
• ✅ Optimize vehicle usage
• ✅ Track business mileage costs (for tax deductions or reimbursements)

🧠 How to Calculate Gas Expense

✅ Formula:

Gas Expense = (Total Distance ÷ Fuel Efficiency) × Fuel Price per Unit

📘 Example:

• Total Distance = 300 km
• Vehicle Mileage = 15 km/l
• Fuel Price = ₹110/liter
• Gas Expense = (300 ÷ 15) × 110 = ₹2,200

This is the estimated cost for your trip or commute.
