Savings Per Year Estimator Equation

The fuel price estimations are calculated based on common, average price-spreads and other economic factors that are subject to industry benchmarks. An example of this equation can be seen below.

Algebraic Formula

(a-c=b)*(x/(z/3.75))

a = Highest average price of fuel available (by town).

b = Difference in averages between the highest and lowest averages stated. This indicator does include motorway prices, which are considered anomalies in the fuel price market.

c = Lowest average price of fuel available (by town).

x = Total litres used during the year. Calculated by dividing the MPL (Miles Per Litre) and the average mileage for that year.

z = Average Miles Per Gallon.

3.75 = Conversion rate of litres to US gallons. 1 US liquid gallon = 3.785 litres.

Real-Life Formula

Unleaded

(138.0p-113.9p=24.1p)*(937.5L/(40*3.75)

Breakdown

138.0p per litre was the highest average price (by town) for unleaded fuel at the month end (March 2019).

113.9p per litre was the lowest average price (by town) for unleaded fuel at the month end (March 2019).

24.1p per litre was the difference in price per litre for unleaded fuel. These figures also include known motorway services, where fuel prices are considered anomalies.

937.5 litres was the calculated total amount of litres used in a year if one was travelling 10,000 miles per year with an average MPG of 40.

Diesel

(146.0p-124.9p=21.1p)*(750.0L/(50*3.75)

Breakdown

146.0p per litre was the highest average price (by town) for diesel fuel at the month end (March 2019).

124.9p per litre was the lowest average price (by town) for diesel fuel at the month end (March 2019).

21.1p per litre was the difference in price per litre for diesel fuel. These figures also include known motorway services, where fuel prices are considered anomalies.

750 litres was the calculated total amount of litres used in a year if one was travelling 10,000 miles per year with an average MPG of 50.

Super Unleaded

(152.9p-119.9p=33.0p)*(1500.0L/(25*3.75)

Breakdown

152.9p per litre was the highest average price (by town) for super unleaded fuel at the month end (March 2019).

119.9p per litre was the lowest average price (by town) for super unleaded fuel at the month end (March 2019).

33p per litre was the difference in price per litre for super unleaded fuel. These figures also include known motorway services, where fuel prices are considered anomalies.

1500 litres was the calculated total amount of litres used in a year if one was travelling 10,000 miles per year with an average MPG of 25.

(161.9p-134.9p=27.0p)*(1071.4L/(35*3.75)

Breakdown

161.9p per litre was the highest average price (by town) for premium diesel fuel at the month end (March 2019).

134.9p per litre was the lowest average price (by town) for premium diesel fuel at the month end (March 2019).

27p per litre was the difference in price per litre for super unleaded fuel. These figures also include known motorway services, where fuel prices are considered anomalies.

1071.4 litres was the calculated total amount of litres used in a year if one was travelling 10,000 miles per year with an average MPG of 35.
