An online gas equipment payback calculator will help you calculate the payback period for installing gas equipment on a car. Takes into account the cost of installing gas equipment, annual mileage, fuel consumption (gasoline and gas), fuel prices. Shows savings and payback period.
LPG (gas cylinder equipment) allows the use of liquefied petroleum gas (LNG) as fuel instead of gasoline. The payback depends on the cost of installation, mileage, the difference in prices for gasoline and natural gas, and fuel consumption. Typically, HBO pays for itself in 1-3 years with a mileage of 15,000-20,000 km/year. Payback formula: Payback period = Installation cost / (Savings per month × 12).
Let's look at practical examples of calculating the payback of gas equipment for various vehicles and operating conditions:

To get an accurate result, follow our recommendations when calculating the payback of gas equipment.
Indicate the actual annual mileage of the car - this is critical for an accurate calculation
Gas consumption is usually 10-20% higher than gasoline consumption due to lower combustion heat
Consider the current prices for gasoline and natural gas in your area, they may vary
Remember the cost of gas equipment maintenance (filter replacement, setup) when calculating the payback
The payback period for gas equipment depends on the cost of installation, annual mileage, fuel consumption and the difference in prices for gasoline and gas. Typically, HBO pays for itself in 1-3 years with a mileage of 15,000-20,000 km/year. With high mileage (30,000+ km/year), the payback can be 6-12 months.
LPG is beneficial when the annual mileage is high (from 15,000-20,000 km/year) and there is a significant difference in prices for gasoline and gas (usually gas is 30-40% cheaper). With low mileage (less than 10,000 km/year), the payback may exceed 3-4 years, which makes the installation less attractive.
Savings = (Annual mileage × Gasoline consumption / 100 × Gasoline price) - (Annual mileage × Gas consumption / 100 × Gas price). For example, with a mileage of 20,000 km/year, gasoline consumption of 10 l/100 km (price 55 ₽/l), gas consumption of 12 l/100 km (price 35 ₽/l): Savings = 110,000 - 84,000 = 26,000 ₽/year.
Gas consumption is usually 10-20% higher than gasoline consumption due to the lower calorific value of gas. If a car consumes 10 liters of gasoline per 100 km, gas consumption will be approximately 11-12 liters per 100 km. This is a normal difference and is taken into account when calculating savings.
The cost of installing gas equipment depends on the type of equipment, the number of engine cylinders and the region. On average, installing a 4th generation gas equipment costs 35,000-50,000 rubles, and a 5th generation gas equipment costs 50,000-80,000 rubles. 6th generation HBO can cost 80,000-120,000 rubles.
With a mileage of 15,000 km/year and a difference in prices for gasoline and gas of 20 ₽/l, the payback for gas equipment will be approximately 2-2.5 years. With more mileage the payback is faster, with less mileage the payback is slower. The exact calculation depends on fuel consumption and prices in the region.
Gas has a lower calorific value compared to gasoline (about 46 MJ/kg for propane versus 44 MJ/kg for gasoline), but due to the lower energy density per unit volume, the consumption per liter is 10-20% higher. This is normal and is taken into account in the calculations.
Payback period = Installation cost / (Annual savings / 12). For example, installation 45,000 ₽, annual savings 26,000 ₽: Payback period = 45,000 / (26,000 / 12) = 45,000 / 2167 = 20.8 months ≈ 1.7 years.
With low mileage (less than 10,000-15,000 km/year), LPG can pay for itself in 3-4 years or more, which makes the installation less attractive. However, if you plan to increase the mileage or keep the car for a long time, the installation may be worth it.
For a profitable installation of HBO, the difference should be at least 15-20 ₽/l. With a smaller difference, the payback may exceed 3-4 years. The optimal difference is 20-30 ₽/l, which ensures payback in 1-2 years with a mileage of 20,000+ km/year.
When calculating the payback, take into account the cost of gas equipment maintenance: replacing gas filters (2000-3000 ₽ every 10,000-15,000 km), setting up equipment (1000-2000 ₽ once a year). This can increase the payback period by 2-3 months.
HBO pays for itself in a year with high mileage (30,000+ km/year) and a significant difference in prices for gasoline and gas (20+ ₽/l). With an average mileage of 20,000 km/year, the payback is 1.5-2 years, with low mileage (10,000 km/year) - 3-4 years.
For a quick payback for gas equipment (6-12 months), a long mileage is required - from 30,000 km/year or more. At this range, the fuel savings are significant and quickly cover the cost of installation. This is normal mileage for commercial vehicles.
Saving per 1 km = (Gasoline consumption / 100 × Gasoline price) - (Gas consumption / 100 × Gas price). For example, gasoline consumption is 10 l/100 km (55 ₽/l), gas consumption is 12 l/100 km (35 ₽/l): Savings = (10/100 × 55) - (12/100 × 35) = 5.5 - 4.2 = 1.3 ₽/km.
Engine type affects fuel consumption and installation cost. Installation on injection engines is simpler and cheaper, on carburetor engines it is more difficult. Gas consumption depends on the type of engine, but is usually 10-20% more than gasoline consumption.
For trucks with high mileage (50,000+ km/year), LPG pays for itself very quickly - in 6-12 months. The formula is the same: Payback period = Installation cost / (Annual savings / 12). High consumption and long mileage provide significant savings.
Engine power loss on gas is usually 5-10% and can have a minor impact on fuel consumption and economy. However, this impact is usually small and not critical for calculating payback. Most drivers don't notice a significant difference.
Gas equipment requires regular maintenance: replacing gas filters every 10,000-15,000 km (2000-3000 ₽), setting up equipment once a year (1000-2000 ₽), checking the tightness of connections. These costs must be taken into account when calculating the return on investment.
Diesel engines are equipped not with LPG (gas), but with LPG for diesel (methane) or dual-fuel systems. Such systems are more expensive and more complex, the payback may be different. Installation of methane equipment is usually considered.
With a difference of 25 ₽/l and a mileage of 20,000 km/year, gasoline consumption of 10 l/100 km: Savings = 20,000 × 10 / 100 × 25 = 50,000 ₽/year. With an installation cost of 45,000 ₽: Payback period = 45,000 / (50,000 / 12) = 10.8 months ≈ 11 months.
First year savings = Annual savings - (Installation cost / Payback period in years). For example, annual savings 26,000 ₽, installation 45,000 ₽, payback period 1.7 years: Savings for the first year = 26,000 - (45,000 / 1.7) = 26,000 - 26,471 = -471 ₽ (not paid off yet).
Savings over 3 years = (Annual Savings × 3) - Installation Cost. For example, annual savings 26,000 ₽, installation 45,000 ₽: Savings for 3 years = (26,000 × 3) - 45,000 = 78,000 - 45,000 = 33,000 ₽.
The type of gas equipment affects the cost of installation: the 4th generation gas equipment is cheaper (35,000-50,000 rubles), but may have higher consumption. 5th generation gas equipment is more expensive (50,000-80,000 rubles), but more economical. More expensive equipment takes longer to pay for itself, but may provide better savings.
To calculate the total payback for multiple vehicles, add up the installation cost of all vehicles and the total annual savings: Total payback period = Total installation cost / (Total annual savings / 12).
When calculating the payback, use current prices for gasoline and gas. If prices change, recalculate the savings. Gas prices typically rise slower than gasoline prices, which can improve your payback over time.
LPG for an old car can be beneficial if long-term operation and sufficient mileage are planned. However, please note that the cost of installation should be commensurate with the cost of the car. On a very old car, installation may not be justified.
When calculating, take into account the actual cost of installation, taking into account discounts and promotions. A 10-20% discount on installation can reduce the payback period by 2-3 months. Use the current installation price in your calculations.
The minimum mileage for gas equipment to pay for itself within a reasonable period of time (2-3 years) is 15,000-20,000 km/year with a difference in gasoline and gas prices of 20 ₽/l. With less mileage, the payback period exceeds 3-4 years, which may not be profitable.
When using a loan, consider the interest: Actual Installation Cost = Installation Cost + Loan Interest. Payback period = Actual cost / (Annual savings / 12). A loan increases the payback period, but may allow you to install gas equipment immediately.
The region influences the prices of gasoline and gas, which directly affects the return on investment. In regions with a large price difference (20+ ₽/l), the payback is faster. Also, in regions with a developed network of gas filling stations, it is more convenient to use LPG.
