Petrol Calculator



What is a Petrol Calculator?

How much petrol do you need to spend on your journey? You can spend a lot of time guessing, but that could burn a neat little hole in your budget. With the rising costs of petrol, it’s important to be spendthrift and forward thinking when it comes to fuel economy. Doing calculations before you leave home could save you a great deal of money.

Petrol calculator is a free simple online tool that calculates it all for you. You plug in the data and it does the rest, telling you exactly how much cash you’ll need to put aside to get to your destination and back again.

How Do I Use It?

This online calculator needs four pieces of information from you:

  1. Journey Distance - specified in miles
  2. In order to include return journey, select the "include way back" checkbox below the input field - the distance value will double.
  3. Your Car's Fuel Consumption - specified in MPG (miles per gallon)
  4. If you don't know the exact value of your vehicle's MPG, calculate MPG with our MPG calc. You can also convert litres per 100km to MPG if you know only the l/100km value but not MPG.
  5. Petrol Price - specified in pence per litre
  6. Addition passengers - not including the driver
  7. In this field, indicate the number of adult passengers, if you intend to divide travel expenses.
Fill in the appropriate input fields, and then click the "Calculate" button (to clear the form, click "Reset"). Once you give the petrol calculator this information, in a matter of moments it will produce the almost exact amount of money you will need to put aside for your journey. The adage goes, “measure it and you’ll manage it.” Meaning, the things that we are measuring on a regular basis, are the things that we will gain control of. The increasing use of gasoline is a growing problem in the UK and the world over. Why not take charge of your fuel spending, so that you can spend your money on the things you truly enjoy?

How to Dramatically Drop the Cost of a Journey

How can you improve your MPG? By changing a few habits that you may (or may not) be aware of, you can immediately reduce the cost of a journey, saving fuel and the money used to buy it.

Here are a few actions you can take to save petrol:

  • Streamline Your Vehicle
  • If you have roof racks or any other accessories that are just for appearance, consider removing them. They tamper with the aerodynamics of your car, slowing it down.

  • Stay Away From Idling
  • Idling is a great way to warm your car up, but too much could cost almost a litre of petrol for every hour you idle.

  • Keep Your Speeds Within The Limit and Consistent
  • Accelerating and decelerating isn’t just annoying for your passengers. It also draws on fuel efficiency. Be easy on your speed transitions and stay within the speed limits. Not only do you save money on fines, but the faster you drive, the harder your car works and the more petrol it uses.

  • Have a regular service plan
  • With time, the wear and tear on the changeable parts of your car will cause the engine to work harder, increasing petrol consumption. Regular changes to oil filters, spark plugs, fuel filters and air filters keep your car in prime condition. This alone could improve your gasoline economy exponentially.

How Does The Calculator Work?

The price of gasoline, the distance you’re travelling and the fuel consumption of your car may change over time, but the equation to work out the cost of this travelling remains the same.

Using mathematical algorithms that do the same job of predicting airplane trajectories and weather patterns, the petrol calculator can accurately tell you, in a matter of moments, how much money your travels will cost you. It’s science in its simplest form. You don’t need to know how the numbers are crunched because the calculator crunches them for you. At the end of the calculation you’re left with a very accurate costing for your journey.
