National average price: the number behind every fuel price
A national average price is the average price of a fuel across an entire country, combining many individual stations into one representative figure. It is the number behind every price shown on our site, so a single station near you can sit above or below it.

What a national average price is
A national average price is the average price of a fuel across an entire country, combining many individual stations into one representative figure.
It exists because station-level prices constantly differ from one address to the next, even within the same city. A single average gives one number you can compare across countries, weeks and fuel types, at the cost of hiding the local detail.
Built by combining official statistics and independent sources for that country, weighted by how much each one covers.
How far a single station can sit from the average
Real stations spread out around the average, sometimes by a noticeable amount. The chart below is an illustration, not real station data.
Each dot is one station's price on the same day. Real spreads vary by country and by how many stations are listed.
Illustrative example. The proof of per-station price differs by country and by how competitive the local market is.
How the average is built
Not every country publishes its own official average, so the figure behind a price is built differently depending on where you look. Where an official series exists, it is given priority; where it doesn't, independent sources are combined instead.
What a national average is not
It's worth being precise about what this figure is, and isn't.
Why the internal spread matters
A country's own internal spread can be as large as the gap between two neighbouring countries. A large country with regional taxes, remote areas or big cities and rural areas mixed together will show more internal variation than a small, uniform one.
That's a reason to treat the national figure as a useful starting point, not a precise prediction of what you'll pay at any one pump.
How this shows up on FuelTheGuide
Every price, chart and ranking on our site is built from national averages, refreshed weekly. When we say a country's diesel price is a given figure, that is what it means: this week's national average for that fuel, from the sources listed for that country.
It's also why we show each price's sources and its update date. If a figure looks off for a station you know, the national average is doing its job, describing the country as a whole, not any one place in it.

Why is the price I see on our site different from the price at my local station?
A national average is exactly that: an average. Local prices vary with the station's location, brand and competition, so any single pump can sit above or below the country figure by a meaningful margin.
Does the average include every fuel station in a country?
Not necessarily. Official series rely on a sample of stations chosen to be representative. Independent aggregators collect more stations but still not every pump. In both cases the goal is a figure that reflects typical prices, not a census.
Why do some countries look like they have almost no variation?
Some countries set a government-fixed pump price, or subsidise fuel so heavily that the official price is the same everywhere. In those cases the national average and the station price are the same by design.
Can I see prices for a specific city or region instead?
Not on this site. We focus on national averages because they are available for the widest range of countries and allow fair cross-country comparisons. City or regional data, where it exists, is much patchier.
