Petrol Price Per Litre Explained: What You Are Really Paying For
When you pay £1.48 per litre for petrol in the UK or €1.78 in Germany, where does that money actually go? The answer surprises most drivers: the majority goes to the government in taxes, not to oil companies. This guide breaks down every component of the petrol price per litre with real 2026 numbers.

The five components of petrol price per litre
| Component | What it is | Who gets it | Does it change with crude? |
|---|---|---|---|
| Crude oil cost | Cost of the raw petroleum extracted from the ground | Oil producers (Saudi Aramco, ExxonMobil, etc.) | Yes — daily |
| Refining margin | Cost of converting crude to petrol + refinery profit | Refineries | Partly — crack spread fluctuates |
| Distribution & retail | Transport to depot, forecourt costs, retail margin | Fuel distributors, petrol station operators | Slightly |
| Excise duty | Fixed government tax per litre | Government | No — fixed amount |
| VAT | Percentage tax on the total pump price | Government | Yes — rises/falls with price |
Crude oil: the global commodity base
Crude oil is traded globally in US dollars per barrel. One barrel = 159 litres. At Brent crude of $80/barrel:
- $80 ÷ 159 litres = $0.503/litre crude cost
- At EUR/USD 1.10: approximately €0.457/litre
- A barrel of crude yields roughly 47% petrol (approximately 75 litres), so crude cost allocated to petrol: $80 ÷ 75 ≈ $1.07/litre of petrol equivalent
The crude-to-petrol allocation accounts for the fact that a barrel yields many products (diesel, jet fuel, LPG, etc.) — accounting conventions vary, but a reasonable estimate is that crude represents €0.50–0.65/litre of the petrol wholesale cost. For the barrel definition, see our barrel of oil glossary entry.
Refining margin: the crack spread
The refining margin is the difference between the value of refined products (petrol, diesel, jet fuel) and the cost of crude oil. This "crack spread" is a key variable — it can range from near-zero during refinery oversupply to $30–40/barrel during supply crunches.
In 2026, typical European gasoline refining margins are approximately $8–14/barrel (~5–9 ct/litre), reflecting adequate refinery capacity after capacity rationalisation post-COVID. High complexity refineries earn higher margins from the same crude. For refinery economics, see our refinery glossary entry and the crack spread glossary entry.
Taxes: the dominant component in Europe
In most European countries, taxes account for over half the pump price. There are up to three tax layers:
- Excise duty (fuel duty): A fixed amount per litre, set by national law. Does not vary with the oil price. UK: 57.95p/l; Germany: 65.45 ct/l; France: ~68 ct/l. See our excise duty entry.
- VAT: Applied as a percentage on the full pump price (including excise). UK: 20%; Germany: 19%; France: 20%; Italy: 22%. Because it is percentage-based, VAT rises in absolute terms when crude prices are high. See our VAT on fuel entry.
- Carbon levy: A relatively new layer in Germany (nEHS: ~7 ct/l on petrol), UK (via ETS for refinery costs), Canada (federal carbon levy: ~17 ct/l on petrol in 2026), and Nordic countries.
Country-by-country breakdown (2026)
| Component | UK (pence/l) | Germany (ct/l) | France (ct/l) | USA (cents/gal ÷ 3.785) |
|---|---|---|---|---|
| Crude + wholesale | ~38p | ~56 ct | ~56 ct | ~55¢/l |
| Refining + distribution | ~12p | ~10 ct | ~10 ct | ~8¢/l |
| Retail margin | ~5p | ~6 ct | ~5 ct | ~5¢/l |
| Excise/duty | 57.95p | 65.45 ct | ~68 ct | ~13¢/l (federal + avg state) |
| Carbon levy | — | ~7 ct | ~4 ct | — |
| VAT | ~28p (20%) | ~28 ct (19%) | ~30 ct (20%) | ~3¢/l (sales tax varies) |
| Total pump price | ~148p | ~178 ct | ~177 ct | ~91¢/l (~$3.45/gal) |
| Tax share | ~58% | ~57% | ~57% | ~18% |
The US-Europe comparison is striking: the crude + refining + distribution cost per litre is broadly similar ($0.68 vs €0.72). The difference is entirely taxes: European governments take ~57% of the pump price; the US takes ~18%.
Why do petrol prices change?
Day-to-day pump price changes are driven by the wholesale (pre-tax) component — crude oil price movements and refining margin fluctuations. Taxes are fixed (excise) or lag (VAT adjusts as price changes, but the rate is set). The most important drivers of pump price changes:
- Crude oil benchmarks (Brent, WTI): The primary variable. A $10/bbl crude move → approximately 6–8 ct/l pump price change, with a 2–6 week lag.
- Currency (EUR/USD, GBP/USD): Crude is priced in USD. A weakening domestic currency increases the local-currency cost of crude even if the dollar price is flat.
- Refining margins: Can move independently of crude. Planned or unplanned refinery outages, seasonal demand shifts (winter diesel demand), and new product specifications all affect crack spreads.
- Government tax changes: Excise duty changes (UK fuel duty freeze, German nEHS increases) have a direct immediate effect on pump prices.

Frequently asked questions
-
How much of the petrol price is tax?
- In the UK, ~58% (fuel duty 57.95p + VAT 20%). In Germany, ~57% (Energiesteuer 65.45 ct + carbon levy 7 ct + VAT 19%). In France, ~57% (TICPE ~68 ct + carbon levy + VAT 20%). In the US, only ~18% (federal 18.4 cents/gallon + state average ~30 cents/gallon). The crude oil and refining cost is broadly similar globally — taxes explain the price gap between countries.
-
What percentage of petrol price is crude oil?
- Crude oil represents approximately 25–35% of the pump price in high-tax European markets, and 40–55% in low-tax markets like the US. At $80/barrel Brent, the crude cost per litre of petrol is roughly €0.55–0.65/litre — similar across countries. High European taxes compress crude's percentage share, making it appear smaller even though the absolute crude cost is the same.
-
Why do petrol prices change daily but taxes don't?
- The wholesale (pre-tax) component changes with daily crude oil prices, refining margins, and exchange rates. Excise duty is a fixed amount per litre set by legislation — it only changes when parliament changes the rate. VAT is percentage-based so it moves with the total price, but the rate is fixed. Day-to-day pump price moves are almost entirely driven by the wholesale component, which feeds through in 2–6 weeks.
