Petrol Cost Calculator

The Petrol Cost Calculator is a powerful and user-friendly tool designed to help you accurately estimate your petrol expenses for any journey or time period. Whether you’re planning a single road trip, calculating your daily office commute cost, or managing your monthly fuel budget, this tool makes it incredibly simple.

By entering just a few basic details — distance, fuel efficiency, petrol price, and trip frequency — you can instantly know how much petrol you’ll use and how much it will cost. It’s ideal for individuals, businesses, delivery drivers, and anyone who wants better control over fuel expenses.

How the Petrol Cost Calculator Works

The tool uses three primary data points to determine the total cost of your trip:

1. Distance (in kilometers) — the total length of your journey.
2. Fuel Efficiency (in km/l) — how far your vehicle can travel on one liter of petrol.
3. Petrol Price (in Rs/L) — the current price per liter in your area.

Based on this input, the calculator computes:

• Total Distance Covered
• Total Petrol Used
• Total Petrol Cost
• Cost Per Kilometer

It also factors in whether you’re making a one-way or round trip, and allows you to calculate daily, weekly, or monthly petrol costs, including adjustable workdays per week.

Step-by-Step Guide to Using the Petrol Cost Calculator

Follow these simple steps to get accurate results:

1. Enter Distance – Type the distance of your trip in kilometers (e.g., 50 km).
2. Input Fuel Efficiency – Enter how many kilometers your vehicle travels per liter of petrol (e.g., 14 km/l).
3. Add Petrol Price – Specify the current petrol price in your area (e.g., Rs 295/L).
4. Select the Period – Choose whether you want to calculate for a single trip, daily, weekly, or monthly basis.
5. Choose Trip Type – Select One Way or Round Trip depending on your travel.
6. (Optional) Enter Days per Week – If you choose weekly or monthly, specify how many days you drive per week.
7. Click “Calculate” – The tool will display a progress bar, then instantly show your results.
8. View the Summary – Check the total distance, petrol used, cost per km, and total cost in a clear summary card layout.
9. Copy or Share Results – Use the built-in buttons to copy your summary or share it via social media or messaging apps.
10. Reset Anytime – Click the “Reset” button to clear all inputs and start a new calculation.

Practical Example

Scenario:
You drive 30 km daily (one-way) to work, your car gives 15 km/l, and the petrol price is Rs 300/liter.

Steps:

• Enter distance: 30
• Fuel efficiency: 15
• Petrol price: 300
• Period: Daily
• Trip type: Round Trip

Result:

• Total Distance: 60 km (30 km x 2)
• Petrol Used: 4.00 L (60 / 15)
• Total Cost: Rs 1,200
• Cost per km: Rs 20.00

If you drive 5 days a week, your weekly cost would be Rs 6,000, and your monthly estimate (4.345 weeks) would be approximately Rs 26,070.

This helps you plan budgets, evaluate car efficiency, or compare petrol costs before deciding on longer commutes or trips.
