How to calculate gas mileage

Fuel consumption calculator

On our website you will find not one fuel consumption calculator, but two at once (switched by clicking the mouse or touching your finger on touch screens):

1. The first one calculates fuel consumption per 100 km (average consumption calculator by distance and amount of fuel consumed), and also allows you to calculate online the cost of gasoline consumed by a car per 1 km of travel.
2. The second calculator will help you calculate fuel for the travel distance (total quantity and cost), based on the travel distance and the average consumption of gasoline, gas or diesel fuel in your car.

Each fuel calculator calculates fuel consumption and cost based on the data you enter. The more accurate the initial data for calculations, the more accurate the result will be.

How to calculate fuel consumption per 100 km

To calculate fuel consumption per 100 km, you must first measure the amount of gasoline, gas or diesel fuel (depending on what the car is driven on) consumed by the car over a certain mileage.

The easiest way to do this is as follows:

• Fill up a full tank of gasoline at the gas station until the safety lock on the fuel nozzle trips;
• Reset the odometer (distance counter on the instrument panel) to zero;
• When the odometer shows at least 200-300 kilometers (the more, the more accurate the calculation results will be), refuel again “to capacity”.

After refueling, keep the receipt, on which you should also write down the odometer readings so as not to forget anything. Now we have all the data necessary to calculate average fuel consumption on the calculator, namely:

• Amount of gasoline consumed (volume of the second filling);
• Distance traveled (according to odometer readings);
• Price for 1 liter of fuel.

Transfer all these values ​​into the first calculator and get the finished result: average gasoline consumption per 100 km and the cost of 1 km.

Keep in mind that the resulting flow rate is not constant and can vary depending on many factors. For anyone interested, we recommend a good article on how to reduce fuel consumption in a car.

How to calculate fuel for travel distance

Calculating fuel for distance is much easier. To do this, you need three types of initial data:

1. Average car fuel consumption;
2. Planned travel distance;
3. Price for 1 liter of fuel.

You can find out the average fuel consumption from your car's owner's manual, or determine it in a practical way (described above) using our first calculator.

Enter all this data into the appropriate fields of the second calculator and receive calculation results online: the total fuel consumption required for the travel distance, and its total cost.

How to calculate fuel consumption

Spending on fuel is a mandatory expense item for any car equipped with an internal combustion engine. You can find out about expenses yourself by making a simple calculation of fuel consumption. How to do this correctly, and at the same time find out the expenses for each kilometer of mileage?

Experience shows that high fuel consumption can sometimes greatly sadden even a very wealthy person. Well, the general public is trying to buy cars that are guaranteed not to devour the budget with their exorbitant appetite. Another thing is that fuel consumption in real conditions may differ markedly from the data declared by manufacturing companies - for example, measurements on the European NEDC driving cycle were carried out under conditions that differed markedly from the usual operating conditions.

Calculating the consumption of gasoline or diesel fuel can be done easily and simply using numerous online calculators, although it is not forbidden to do it yourself, since there is nothing particularly complicated about it.

Necessary steps to calculate fuel consumption

First of all, fill up a full tank of gasoline or diesel fuel, not forgetting to reset the daily mileage, which is located on the instrument panel next to the main mileage of the car, which is not recommended to be “reset”. After this, you need to drive a couple of hundred kilometers, then refuel the car again to a full tank in order to find out how much fuel will enter the tank. After this, you can find out the real average fuel consumption of your vehicle.

Where to go and what to do next

How to correctly calculate consumption? If you want to find out the whole truth about the appetites of your car, then try to do without “cheating”, that is, without conditional cheating. Don't try to barely press the gas pedal or try to coast all the time - behave naturally and drive in a manner familiar to you. It is highly advisable that your route runs not only through the city, but also along the highway - this way you can find out the average fuel consumption. It is recommended to devote approximately two-thirds of your time to the city crowd, and the rest to the freedom of country roads. After you have clocked two or three hundred kilometers on the odometer, refuel to capacity again. This way you will find out how much fuel the trip actually took and compare the actual consumption with the figures provided by your on-board computer.

Formula for calculating fuel consumption

Now let's calculate the fuel consumption of the car. A very simple formula is used for this: you divide the amount of fuel consumed by the distance traveled and multiply the resulting number by one hundred (100). So that this doesn’t seem complicated to you, let’s give an example. Let's say you spent 28 liters for 300 kilometers. The calculations will be: 28 / 300 x 100 = 9.3 l/100 km.

Formula for calculating fuel costs

Once you know your actual fuel consumption, you can find out how much each kilometer of travel costs you using the data described above, and then be happy or horrified. The formula is as follows: the average consumption value is multiplied by the cost of fuel and divided by 100. So, during the test trip you got 9.3 l/100 km. Let's say your car consumes AI-95 gasoline, which now costs about 46 rubles per liter. The result obtained: 9.3 x 46 / 100 = 4.3 rubles per kilometer or 430 rubles per 100 kilometers.

Why fuel consumption may be too high

Please note: our hypothetical figure of 9.3 l/100 km is not the worst result of average fuel consumption. Let’s say this is exactly how much you should have gotten, but calculations showed, say, 12-14 liters at the usual rhythm of movement. What are the reasons for the excessive consumption of “golden” fuel today? There are a lot of them, starting with driving style and ending with numerous technical faults.

Before looking for the cause in technical problems, we suggest starting small, and first check the tire pressure. If they are reduced, then the engine's appetite may increase quite noticeably. Is there a roof rack? It creates aerodynamic drag and this also increases the fuel consumption of your car. And the turned on air conditioner can also have its say.

As for technical malfunctions, the culprit may be a dirty air filter, which puts a difficult barrier in the air path, or faulty injectors or a fuel pump. A non-optimal fuel-air mixture ratio directly affects the scale of fuel consumption, and in particularly advanced situations can cause serious breakdowns. Worn spark plugs, high-voltage wires and ignition coils can also increase fuel consumption and significantly affect the behavior of the car.

Faulty brakes, such as a stuck caliper, failed wheel bearings and unadjusted wheel alignment, also have a direct impact on costs. But, we repeat, all these malfunctions have very characteristic consequences, which are quite difficult not to notice. If the caliper “wedges,” the brake disc will get very hot, the long-lived bearing will hum, and due to a crooked wheel alignment, the tires will quickly become unusable.

How to reduce fuel consumption

There is a list of rules to reduce fuel consumption. First of all, remember that the technical condition of the car depends on your appetite. If you are a driver who professes an active driving style, and at the same time want to spend less on gasoline, then break your habits.

Accelerate smoothly, try to avoid hard acceleration and shift up early. If the road conditions and terrain allow, then practice coasting. By the way, at traffic lights and in dense traffic jams, you yourself can play the role of the stop-start system (automatically turning the engine off and on during stops), which can now often be found on modern cars - just turn off the unit during more or less long pauses. When you get out on the highway, remember that driving fast at sub-optimally high engine speeds also leads to noticeable overruns. By choosing a speed of 100-110 km/h you will not go beyond reasonable fuel consumption.

Fuel consumption calculator

The fuel consumption calculator allows you to make 2 types of calculations:

• Calculation of the amount of fuel consumed per trip. You must indicate the average fuel consumption of the vehicle and the distance traveled.
• Calculation of average consumption per 100 km. You must indicate the distance traveled and the amount of fuel consumed.

The constantly rising price of gasoline is hitting the pockets of most motorists. Expenses for refueling a personal car make up a significant part of the budget of the average Russian.

According to the results of a study by the analytical agency AUTOSTAT, as of February 2019, 42% of surveyed motorists spend more than 4,000 rubles on gasoline monthly.

How to save on gasoline

Factors affecting fuel consumption

Choosing an economical car

The most economical cars today are cars with an electric engine. They run on batteries that require electricity to charge. Such charging is much cheaper than gasoline.

They are followed by hybrid cars. They combine a gasoline engine with an electric one. The savings in this option are significant compared to all-gasoline or diesel engines.

Neither the first nor the second are common in Russia, so you will probably have to choose the classic option. The most economical among them are those with the smallest weight and smallest engine capacity. Manufacturers usually indicate the average consumption of models in the specifications. But it’s safer to rely on reviews from real owners.

Fuel consumption calculator

An online calculator will help you calculate your car's fuel consumption; has 2 usage options:

1. Get the total fuel consumption of the car by indicating the distance traveled and the average fuel consumption of the vehicle.
2. Get the average consumption per 100 km, indicating the distance traveled and the amount of fuel consumed.

Online fuel consumption calculator

Have you ever wondered how much a trip to the store actually costs you? How much gasoline (diesel fuel) do you need to get to your relatives who live in another city? Or maybe you're just interested in seeing your car's mileage per 100 kilometers.

The calculator on this page is completely free and is designed to help you get a realistic idea of ​​what the real cost of all trips is.

How to calculate fuel consumption and trip cost?

The simplest way to calculate how much fuel a car spends per 100 km requires the driver to fill the gas tank completely, then drive a short distance and look at the result. After this, the calculation is carried out using the simplest formula Рт = L/Km x 100 , which stands for:

Fuel consumption per 100 km = Volume of fuel burned (in liters) / Distance traveled (in km) x 100

This option is simple but effective: it allows you to obtain up-to-date data on the rate of diesel fuel consumption. Unfortunately, this somewhat limits the accuracy of the method, since no additional parameters are taken into account.

You can also calculate fuel consumption using the standard formula Qn = 0.01 x Hs x S x (1 + 0.01 x D) , where Qn is the standard consumption in liters; Hs – base consumption in liters per 100 km, declared by the manufacturer; S is the current mileage, and D is a clarifying factor (it can either decrease or increase the result).

The coefficient is selected according to the following rules:

• Air conditioning or climate control system – plus 7%;
• Operation within urban areas (from 250 thousand inhabitants) – plus 15%;
• After 100 thousand kilometers and 5 years of operation - plus 5%;
• Check regulations for your region. Depending on the climate, up to 20% can be added.

To calculate fuel consumption as accurately as possible, a calculator is much better. Knowing the number of kilometers traveled and the volume of gasoline consumed, you can get accurate consumption figures without resorting to independent calculations.

The obtained data can be used for several purposes:

• Expense planning. If you usually only use your car for intracity trips, then it makes sense to calculate your gas mileage before going on a long trip. Using an online fuel calculator, you can get even more accurate data, including the cost of a liter of gasoline.
• Preventing unpleasant situations. An experienced motorist often finds himself in a situation where he needs to get somewhere urgently and does not want to waste time refueling. Knowing the gasoline consumption per 100 km, you can estimate whether you can reach the nearest gas station with the liters remaining in the gas tank.
• Diagnostics. Checking the rate of fuel consumption should be carried out at least once every six months. The obtained data should be compared with the basic indicators declared by the manufacturer. A large difference in the data obtained may indicate a malfunction.

Basic indicators are the standard that a machine meets after it leaves the assembly line. To find out the fuel consumption standards for your car model, check out the table.

Fuel consumption, fuel consumption calculation

Try calculating the fuel consumption for your vehicle. It's very simple.

Fuel consumption

It's no secret that transport consumes fuel - gasoline, diesel fuel, gas. And if you want to know the average fuel consumption of your vehicle, then this service is for you. You just need to indicate how many kilometers you have driven and how much fuel you have used. The fuel consumption calculator will show the fuel consumption of your vehicle, as well as how much money you spent to cover this distance.

Fuel consumption calculation

Calculation of fuel consumption is simple. It is enough to multiply the amount of fuel consumed by 100 and divide the result by the mileage. Let's look at an example - Kamaz fuel consumption . Let's assume we drove from Moscow to Novosibirsk (you can calculate the distance here) and drove 3300 km. At the same time, 825 liters of diesel fuel were burned. By entering these data into the fuel consumption calculator, we get fuel consumption equal to 25 liters per 100 km. Or let’s calculate it manually: 825 * 100 / 3300 = 25 liters per 100 km. And before the trip, check your condition using an alcohol calculator if there was a feast the day before. And also try to calculate the transport tax.

How to calculate gasoline consumption

How to calculate gasoline consumption is described above. Now a few words about how to calculate consumption as accurately as possible. The recommendation here is simple - the greater the mileage (and therefore the more fuel consumed), the more accurate the data obtained after the calculation. Therefore, it is more correct to calculate the consumption when the mileage is more than 1000 km. Until then, collect receipts from gas stations to know the exact amount of fuel consumed. If you know your fuel consumption and mileage, calculate your total fuel consumption.
