Calculating fuel cost per mile
Calculating the fuel cost per mile can help you budget for a road trip and determine how much fuel you'll need. It can also help you understand your vehicle's fuel efficiency and make more informed choices when planning your route.
To calculate the fuel cost per mile, you'll need to know the distance travelled, your vehicle's fuel efficiency or fuel consumption, and the price of fuel per unit volume (e.g., price per gallon or litre).
The formula for calculating fuel cost per mile is:
Fuel Cost per Mile = (Distance / Efficiency per Gallon) x Cost per Gallon
For example, if your vehicle travels 45 miles and uses 1.75 gallons of fuel, you would divide 45 by 1.75, resulting in a fuel efficiency of 25.7 miles per gallon for that trip. Then, you would multiply the fuel efficiency by the fuel price per gallon. Let's assume the fuel costs $4 per gallon:
7 miles/gallon x $4 per gallon = $0.156 per mile
So, for this example, your fuel cost per mile is approximately $0.16.
You can also calculate fuel consumption or fuel efficiency, which is useful if you want to compare vehicles or track your vehicle's performance over time. Fuel consumption is the amount of fuel burned per unit distance, typically measured in litres per 100 kilometres (L/100 km) or miles per gallon (MPG). To calculate fuel consumption, divide the amount of fuel used by the distance travelled.
It's important to note that fuel prices can vary based on location and political factors, and they are subject to constant fluctuation. Additionally, factors such as vehicle type, engine size, tyre pressure, motor oil type, and driving habits can all influence fuel efficiency and overall fuel costs.

Fuel efficiency and cost
There are several ways to calculate the fuel efficiency of a vehicle. Fuel efficiency, or fuel economy, is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. In the context of transport, fuel economy is the energy efficiency of a vehicle, given as a ratio of distance travelled per unit of fuel consumed. This can be calculated in miles per gallon (MPG) or kilometres per litre (kmpl). Fuel consumption, on the other hand, tells us how much fuel a vehicle burns at a certain distance, for example, in litres per kilometre (L/km) or litres per 100 kilometres (L/100km).
Fuel efficiency is dependent on many parameters of a vehicle, including its engine parameters, aerodynamic drag, weight, AC usage, and rolling resistance. It can be improved by careful maintenance and driving habits. For example, driving at a steady speed on highways instead of local routes or city streets can maximize fuel efficiency. Additionally, choosing a smaller car with a smaller engine can greatly reduce fuel costs.
The cost of fuel is dependent on the global oil price, which fluctuates constantly. Political elements, such as regime changes and relationships between countries, can also affect the cost of fuel. The price of gas may also go up or down depending on government interventions, such as taxation.

Factors affecting fuel price
Several factors influence the price of fuel, and these can be broadly categorized into economic and geopolitical factors.
Economic factors include supply and demand, refining and distribution costs, taxes, and market conditions. Supply and demand are fundamental to determining fuel prices. For instance, global demand for crude oil has increased due to economic growth and greater vehicle access, especially in developing countries. This increased demand affects the price of crude oil, which is the most significant contributor to the price of gasoline. The price of wholesale gasoline is influenced by supply and demand factors distinct from crude oil. Gasoline demand usually rises during the summer, leading to higher prices. Distribution and marketing costs also impact the final retail price of gasoline. Taxes play a role as well; federal and state taxes in the US accounted for 17.3% of the retail gasoline price between 2014 and 2023. Market conditions, such as local competition, can also affect fuel prices, with prices varying even between nearby retail stations due to differences in traffic patterns, rent, and supply sources.
Geopolitical factors include events that impact the oil market, such as supply disruptions due to political disturbances or refinery outages. The Organization of Petroleum Exporting Countries (OPEC), which produced about 40% of the world's crude oil between 2000 and 2014, influences oil prices by setting production limits among its members.
Other factors that can influence fuel prices include the cost of other ingredients blended into gasoline, such as fuel ethanol, and the grade of gasoline, with premium-grade gasoline being the most expensive.

Fuel consumption formula
The fuel consumption formula helps to measure how efficiently a vehicle uses fuel. It is calculated by dividing the distance travelled by the amount of fuel used. The formula can be represented as:
Fuel Consumption = Distance Travelled / Fuel Used
For example, if a vehicle travels 335 miles and uses 12 gallons of fuel, the fuel consumption is 27.9 miles per gallon (mpg) or 335 miles / 12 gallons = 27.9 mpg.
If you are using the metric system, the formula can be adjusted to calculate litres per 100 kilometres. This is calculated by multiplying the litres of fuel used by 100 and then dividing it by the kilometres travelled. The formula can be represented as:
Fuel Consumption (L/100 km) = (Litres Used x 100) / Kilometres Travelled
For example, if a vehicle travels 1320 kilometres and uses 100 litres of fuel, the fuel consumption is 7.576 L/100 km or (100 x 100) / 1320 km = 7.576 L/100 km.
It is important to note that fuel consumption can be affected by various factors, such as the weight of the vehicle, the power of the engine, and external conditions such as traffic or weather. Additionally, fuel consumption may vary depending on the type of fuel used, such as diesel or gasoline, as they have different weights and specific fuel consumptions.

Calculating MPG
Calculating your car's miles per gallon (MPG) can help you understand your vehicle's performance and fuel efficiency. This can help you make cost-effective and environmentally friendly driving decisions.
To calculate MPG, you can use a simple formula: Miles Driven / Gallons of Gas Used = MPG.
For example, if you drive 300 miles and use 25 gallons of gas, your MPG is 300/25 = 12.
You can also use an MPG calculator, which is a helpful tool that allows you to calculate your fuel consumption and the cost of your trip. To use this, you will need to input the starting and ending odometer readings and the amount of fuel used for the trip. You can also enter the price per gallon or litre of fuel, and the calculator will tell you the total cost of your trip.
If you want to calculate your MPG manually, you should start by filling your tank completely and resetting your trip odometer to zero. Then, drive as normal until it's time to refill your tank. When you refill, note exactly how much fuel you've added (in gallons) and check your trip odometer to see how many miles you've driven.
It's worth noting that driving habits such as aggressive driving, cold weather, and towing extra weight can negatively impact your MPG.
