e-Go! Fuel Analyser

Need to decide on the best fuel type for your next new car or van?
Then we've got just what you need to reach the right decision.

Our fuel analyser can compare petrol vs diesel, hybrid and electric cars and vans instantly and help you choose the best fuel for your needs.

If this is the first time you've used our fuel analyser then take a minute to read the briefing guide below - it will help you get to the right answer.

Even if you're a veteran then it may still help you to read the guide again anyway.

Think of it as our crumple zone - once you know what it does you'll feel a lot safer.

    What Does It Do?   

What Does Our Fuel Analyser Do?

e-Go! will calculate the total running costs from 1-5 years for petrol, diesel, hybrid and electric vehicles and put them side-by-side so you can see which will be cheapest.

By blending information about your annual mileage and fuel costs with industry leading data on depreciation, maintenance and fuel consumption, we'll help you decide whether or not a swap from traditional fuels to hybrid or electric power will help the planet and your wallet.

    Getting Started   


e-Go! uses pop-ups to display some of the fuel analyser data - if your browser blocks pop-ups then you will need to allow pop-ups for our web site, otherwise you won't be able to see some of the data.

This shouldn't interfere with your settings for other websites - most browsers enable you to allow or block pop-ups from specific sites.

Look for an icon to allow pop-ups in the address bar of your browser, or check your browser settings or browser help guide for more information on how to do this.

Why do we use pop-ups?

Because of the huge volume of data required for the fuel analyses, using pop-ups is the easiest way to display some of the information and calculations in e-Go!, otherwise you would need to do lots of scrolling up and down the page to see all of the data.

We promise we won't abuse pop-ups once you have allowed them for this site. They will be used only to present data and not for advertising or other annoying material.

Getting Started

Choose Your Annual Mileage

e-Go! compares running costs based on mileage, so to get started choose your expected annual mileage from the selection box. This will be used to calculate the key mileage dependant costs of depreciation, maintenance and fuel

Choose Your Vehicles

Next, select the vehicles you want to compare in each fuel category - Petrol, Diesel, Hybrid and Electric.

We'll then instantly show you the forecast running costs per mile for each vehicle over 5 years.

Our running cost forecasts are based on outright purchase, but you can also see the costs including finance.

To do this click on either the 'Personal Finance' or 'Business Finance' buttons for an analysis using personal contract hire or business contract hire.

Detailed analysis

If you're using a computer with a pointing device hold your mouse pointer over the headline pence per mile costs to see a table of running costs over 1-5 years.

On any device you can also scroll down and click on the 'Costs Details' button for any of the fuel types to see all the detail behind our calculations.


We calculate depreciation costs automatically for you using the On-The-Road price of the car and industry standard data on forecast used car values.

You can change the On-The-Road Price for a vehicle to reflect what you actually paid or expect to pay after any discounts; just type a new amount in the On-The-Road box for a vehicle, press the 'Enter' key and we'll work out the depreciation for you.


Maintenance costs are calculated automatically for you using your selected annual mileage and based on independent forecasts for servicing, tyre and mechanical repair costs.


VED is short for 'Vehicle Excise Duty', which is the official name for the 'tax disc' that used to be displayed on cars, but which is now recorded only on a central Government database.

We'll calculate VED costs automatically for you based on the current rates set by the Goverment - these vary according to the CO2 output of the car.

Fuel Costs

For fuel costs we have estimated the price of Petrol, Diesel and Electricity but you can change these - click on the 'Fuel' button for the car.

You'll see a box for the pence per litre cost of Petrol or Diesel; just type in the price you want to use and press the 'Enter' key to change the calculations.

For Plug-In Hybrid and Electric cars you will also need to enter a cost for recharging the battery.

If you use a home charger you can find the cost on your electricity bill - it's the cost per kiloWatt hour you are charged by your electricity provider.

If you use public charging points then use the cost per kiloWatt hour on the charger receipt or invoice.

Don't worry if you don't know any of these costs - we'll put an example value in each box anyway to get you started.

Plug-in Hybrids - Electric Motoring Ratio

If your selected Hybrid car is a Plug-In Hybrid then you will need to specify the percentage of your motoring that uses just the electric motors.

This is to make the fuel cost calculation more accurate - you won't be using petrol or diesel during this motoring, which will reduce your liquid fuel costs, but you will be using electricity, which will increase your recharging costs.

We'll work out the appropriate adjustment to your fuel costs according to the percentage you select.

Don't worry if you don't know the percentage - we'll assume 50% 'electric-only' use unless you select a different percentage.


You will also need to enter your expected annual insurance premium for each vehicle; once again we'll put an example value in the box for you to get started.

Click on the 'Insurance' button below any car to change the annual insurance cost. Remember that your annual insurance premium might be different according to the vehicle you select for each type of fuel.

VAT Recovery

If you are a VAT registered business and can recover all your VAT then we can adjust the Maintenance and Fuel costs for recovered VAT at the standard rate.

Click on the 'Help' button at the top of the fuel analyser page. Scroll down to bottom of the Help screen and check the 'Recover VAT on fuel and maintenance' box.

If you check the box then, for simplicity in the calculation, we will assume that Plug-in and Electric cars are recharged at business/commercial premises so the VAT can be recovered at the 20% rate charged on electricity supplies to non-domestic premises.


You can view all the running costs as charts with the various costs at each stage of the vehicle life. Just click on the 'Charts' button.
