automotive green vehicles# How do you work out fuel cost?

Last Updated: 8th January, 2020

**To estimate the fuel cost for a trip you must know thetripdistance, the average per litre cost of fuel and the vehicle'sfuelconsumption.**

- Divide the trip distance by 100.
- Multiply the result of this by the
**fuel**consumption. - Then multiply this
**figure**by the**cost**of**fuel**/litre.

Likewise, how do you calculate fuel cost?

Take the mileage of the total distance of your tripanddivide it by your miles per gallon to get the number of gallonsof**gas** you will need on your trip. Then multiply that figurebythe current price of **gas**, and the result is the**cost**of **gas** for your road trip.

One may also ask, how much is a full tank of gas? Smaller cars generally have **gas tanks** that hold12gallons worth of **gas**, while larger cars can hold 15 or16gallons. For the purpose of this story, let's say **gas**costs$3.85 a gallon. A car with a 12-gallon **tank** costs$46.20 tofill up while a larger car with a 15-gallon **tank**costs$57.75.

Consequently, how do you calculate work mileage?

Multiply the number of **miles** you drove byyourcompany's approved **mileage** reimbursement rate. Forexample,if you drove 1,000 **miles for work** and thereimbursement rateis 54.5 cents per mile, you would multiply 1,000by .545 whichequals $545.

How far can you travel with 1 Litre petrol?

Anything that is listed as lessthan6-**litres**/100km or more than 16.5km/**1**-**litre**isconsidered to be pretty good. The first (and most common)referenceis **litres** per 100km (**litres**/100km). This ishow many**litres** of **fuel** the car needs in orderto**travel** 100km. **You**'ll often see it referred toas'**fuel** economy'.
