LPG calculator

See how much you can save

If you are still wondering if fitting your car with an LPG system is a  profitable investment and how much farther you can get on a single tank – just check it using our LPG calculator. Use the calculator to perform all calculations required quickly and easily.

Find out how much you can gain and how quickly your LPG system investment will pay off. Simply input your average petrol consumption per 100 km and average monthly travel distance and the LPG calculator will show you just how much you can save per month and year. If you know the LPG system's installation cost, please input them into the calculator as well. If you don't know it, you can leave the default amount (the average cost of installing such a  system in a  typical car). You calculations you receive will be very accurate. The results will immediately show you how much you can save every month and year, as well as how long it will take you to recoup the LPG system's costs.

CHECK YOUR CAR’S RANGE

Thanks to our LPG calculator, you can quickly and easily check how much farther you can travel using LPG for the same amount of money you spend on petrol now. Although the difference in petrol and gas prices alone generates savings and is a convincing argument for driving on autogas, the improved range of your car on LPG undoubtedly provides you with added value and improved travel convenience without frequent refuelling.
