Fuel Calculator

⛽ Fuel Calculator for Tractor, Harvester & Generator

In modern agriculture, diesel and fuel costs are one of the biggest running expenses. Whether you are using a tractor for ploughing, a harvester for harvesting, or a generator for irrigation and power backup, fuel cost directly affects your profit and farm budget.

This Fuel Calculator helps farmers and farm operators estimate fuel requirement and total cost for a specific job before starting the work. It is based on the principle of Specific Fuel Consumption (SFC), which is a common engineering method to estimate how much fuel an engine uses per unit of power and time.

With this tool, you can:

• 🚜 Estimate how many liters of diesel your machine will use
• 💰 Calculate total fuel cost for the job
• ⏱️ See average fuel use per hour
• 🛣️ Track mileage (km per liter) for road travel
• ⚡ Compare diesel vs electric running cost (approximate)
• 🔧 Get efficiency tips to reduce fuel wastage

✅ Who Should Use This Calculator?

• Farmers using tractors, harvesters, or generators
• Custom hiring operators and contractors
• Farm managers planning job costs in advance
• Students and agri-mechanization learners
• Anyone who wants to control fuel expenses in farming

🧮 What Information Do You Need to Enter?

You only need simple details that you already know:

• Type of machine: Tractor, Harvester, or Generator
• Engine power (HP)
• Type of work: Light, Medium, or Heavy
• Area of work: Acre or Hectare (for planning reference)
• Operating time: How many hours the machine will run
• Fuel price per liter
• Road distance (optional): For mileage calculation

Based on this, the calculator estimates fuel consumption using SFC, then shows total fuel required and total cost.

⚠️ This is a planning tool to help you estimate costs before starting work.

📘 How This Fuel Calculator Works

This calculator uses a simple and practical formula based on Specific Fuel Consumption (SFC):

1. Fuel per hour is estimated using: Fuel per hour = Engine HP × SFC × Work Load Factor
2. Total fuel required is calculated as: Total fuel = Fuel per hour × Operating hours
3. Total fuel cost is calculated as: Total cost = Total fuel × Fuel price per liter
4. Mileage (km/l) is calculated (if road distance is given) as: Mileage = Distance traveled ÷ Total fuel used
5. Diesel vs Electric Comparison
   The tool also shows a rough comparison of how much money you could save if the same work is done using an electric machine instead of a diesel one. This is only an approximate reference to support decision making.

🔧 Important Efficiency Tips

• Low tyre pressure can increase fuel consumption by 10–15%
• A dirty air filter can increase fuel use by 5–10%
• Poor maintenance and wrong gear selection can waste fuel
• Regular servicing, correct tyre pressure, and clean filters can save a lot of diesel over a season

⚠️ Important Disclaimer

• This calculator gives approximate estimates based on average SFC values.
• Actual fuel consumption depends on:
  • Soil condition and field type
  • Machine condition and maintenance
  • Operator driving skill
  • Load, speed, and working depth
• Use this tool for planning and comparison, not as an exact measurement.

💡 Why Planning Fuel Use Is Important

• Helps you estimate job cost before starting work
• Helps in budgeting and cash planning
• Helps in comparing diesel vs electric options
• Helps in reducing unnecessary fuel wastage
• Improves overall farm profitability

❓ Frequently Asked Questions (FAQ)

Q1: Is this calculator accurate?
It gives a practical estimate based on average values. Real fuel use may be higher or lower depending on conditions.

Q2: Can I use this for any tractor or machine?
Yes, you can use it for most tractors, harvesters, and generators by entering the correct HP and work type.

Q3: What is SFC?
SFC (Specific Fuel Consumption) means how much fuel an engine uses per unit of power per hour. It is a common method used in engineering to estimate fuel usage.

Q4: Why does work type matter?
Heavy work like ploughing puts more load on the engine, so it consumes more fuel than light work like transport or spraying.
