Fuel retail margin
The difference between the pump price and the wholesale cost of fuel. It covers forecourt operating costs and profit — and is much thinner than most drivers assume, typically 1–5 cents per litre in competitive markets.
Where retail margin sits in the pump price
The fuel retail margin is the final layer in the pump price build-up, added after the refinery gate price, distribution and logistics costs, excise duty, carbon taxes, and VAT have all been stacked. It covers everything the retailer pays beyond the rack price (the wholesale price at which fuel is delivered from the terminal) up to the price charged to the consumer.
For a complete view of how all layers combine, see our guide to what makes up the price at the pump and our refinery gate price entry. The retail margin is typically the smallest single component:
| Component | Approximate share of pump price (UK, 2024) |
|---|---|
| Crude oil cost | ~35 % |
| Refining + distribution | ~10 % |
| Excise duty | ~30 % |
| VAT (20 %) | ~20 % |
| Retail margin | ~3–5 % |
The RAC Foundation publishes detailed UK pump price breakdowns showing each component. The European Commission oil bulletin tracks before-tax and after-tax prices for all EU member states, allowing the implied retail margin to be estimated by comparing the reported pre-tax wholesale price with actual pump prices.
How thin margins really are
The gross retail margin — pump price minus rack price — in the UK typically ran at 5–8 pence per litre (p/l) in 2023–2024, according to DESNZ (Department for Energy Security and Net Zero) data. Against that, typical forecourt costs include:
- Rent or lease: 1–2 p/l
- Staff: 0.5–1 p/l
- Electricity and utilities: 0.3–0.5 p/l
- Payment card processing fees (Visa/Mastercard typically charge 1–1.5 % of transaction value): 1–2 p/l at current pump prices
- Maintenance, insurance, environmental compliance: 0.3–0.5 p/l
After these costs, net fuel margin is often only 0.5–2 p/l. A forecourt selling 5 million litres per year at 1 p/l net earns GBP 50,000 from fuel — a tiny return on a business that may have cost millions to build and requires 24/7 staffing. The Petrol Retailers Association (PRA) in the UK documents the cost structure of independent forecourts in detail.
Rockets and feathers
The "rockets and feathers" phenomenon describes the asymmetric pass-through of wholesale price changes to pump prices: pump prices rise quickly (like rockets) when wholesale costs increase, but fall slowly (like feathers) when wholesale costs drop.
This pattern has been documented in competitive markets including the UK, EU, US, and Australia. The Australian Competition and Consumer Commission (ACCC) monitors Australian petrol prices in detail and publishes annual reports specifically on pricing behaviour. The UK consumer organisation Which? and the RAC Foundation have documented the phenomenon in British markets.
Causes are debated but typically include:
- Inventory timing: Fuel in the tank was purchased at a higher price; the retailer argues it cannot cut the pump price until cheaper stock arrives.
- Signalling and coordination: In markets with few large players, price rises are quickly matched, but price cuts are waited out to see if competitors will hold.
- Search costs: Consumers check prices before filling up less often than retailers change prices, reducing competitive pressure on downside moves.
The UK's Competition and Markets Authority (CMA) launched a specific road fuel market study in 2022 following concerns about wider-than-normal margins during the post-Ukraine price spike, ultimately recommending a new fuel price monitoring framework.
The supermarket effect
Supermarket fuel stations in the UK (Tesco, Asda, Sainsbury's, Morrisons), France (Leclerc, Carrefour), and Germany (Aldi, Lidl, Rewe) consistently price fuel 2–5 p/c per litre below branded independents and oil company stations. The economics are straightforward: supermarkets use low fuel prices to drive footfall into high-margin grocery aisles, effectively cross-subsidising the forecourt from the store.
The CMA's 2023 road fuel final report found that supermarket fuel margins in the UK were indeed lower than non-supermarket sites on average, and that supermarkets had driven meaningful competitive improvements in forecourt pricing. However, it also noted that in rural areas without supermarket competition, prices remained elevated — a finding that prompted recommendations for a new price transparency requirement.
For consumers, the practical implication is that supermarket stations offer systematically better value in the UK and France.

Regulatory oversight
Fuel retail margins are monitored by competition authorities and energy regulators in most OECD countries. Key sources:
- RAC Foundation — UK weekly pump price and component breakdown
- EC Oil Bulletin — EU weekly before-tax and after-tax prices
- ACCC (Australia) — detailed Australian price monitoring including margin analysis
- EIA (US) — weekly US gasoline and diesel retail prices
- Natural Resources Canada — Canadian retail and component data
Where margins widen beyond historical norms, regulators may intervene — the CMA's 2022–2023 fuel study in the UK being the most recent example. Some countries set maximum retail margins by regulation (South Africa, for example, includes a statutory retail margin in its monthly BFP price structure). The government-fixed price and price cap glossary entries cover the broader regulatory toolkit for fuel pricing.
Frequently asked questions
How much does a petrol station make per litre of fuel?
Retail margins are thin — typically 1–5 pence or cents per litre in competitive markets. After operating costs (rent, staff, electricity, card fees), net margins can be under 1 p/c per litre. Most forecourt profit comes from the convenience shop, car wash, and food service.
Why do pump prices not fall immediately when wholesale prices drop?
The "rockets and feathers" phenomenon: prices rise quickly when costs increase but fall slowly when costs drop. Causes include inventory timing, signalling in concentrated markets, and consumer search costs. Competition authorities in the UK, EU, and Australia have documented and investigated the pattern.
Do supermarket fuel stations have lower margins?
Yes. Supermarkets price fuel 2–5 p/c per litre below branded independents on average, using low fuel prices to drive store footfall. They cross-subsidise the forecourt from higher-margin grocery sales.
What is gross vs net retail margin?
Gross retail margin is pump price minus wholesale (rack) price. Net retail margin subtracts forecourt operating costs — rent, staff, electricity, card processing fees, and maintenance. After these costs, net margins are often only 0.5–1.5 p/c per litre.
