Oil above $100/barrel means higher prices every time you fill up. Enter your driving habits below and see exactly how much more the 2026 oil spike is costing you per year.
With oil at $100/barrel, US drivers are paying roughly $0.65 more per gallon than at the start of 2026. For a driver covering 12,000 miles/year at 30mpg, that is about $260 extra per year in fuel alone. At $120/barrel, the extra annual cost rises to approximately $440/year.
Crude oil accounts for roughly 54-60% of the retail price of gasoline in the United States. The rest is made up of refining costs (roughly 15%), distribution and marketing (around 10%), and taxes (around 15-20% at federal and state level combined, though this varies significantly by state).
When crude prices rise, the oil component of your petrol price rises in near-lockstep. The pass-through rate is around 65%, meaning a $10/barrel increase in crude typically adds $0.15-$0.17/gallon at the pump within about 1-2 weeks.
One asymmetry worth knowing: prices at the pump tend to rise faster when crude goes up than they fall when crude comes down. This "rockets and feathers" pattern has been documented by the US Federal Trade Commission and consistently observed across markets.
| Oil Price | Est. US avg pump price | Extra vs. Feb 2026 | Extra cost (12k mi, 30mpg) |
|---|---|---|---|
| $72 (Feb 2026 baseline) | ~$3.20/gal | baseline | $0 |
| $85 | ~$3.51/gal | +$0.31/gal | +$124/yr |
| $100 | ~$3.84/gal | +$0.64/gal | +$256/yr |
| $120 | ~$4.27/gal | +$1.07/gal | +$428/yr |
| $150 | ~$4.92/gal | +$1.72/gal | +$688/yr |
US pump price estimates based on $3.20/gal February 2026 baseline and 65% crude pass-through rate. Actual prices vary by state, grade, and retailer.
In the UK and Europe, pump prices are less directly proportional to crude oil movements because fuel duty makes up a much larger share of the retail price. UK fuel duty is around 53p/litre, which means a 30% rise in crude translates to a smaller percentage increase at the pump.
However, because UK and European pump prices are already significantly higher than the US in absolute terms (typically 140-180p/litre in the UK vs. the equivalent of 85-110p/litre in the US), the absolute extra cost per litre from a given crude move is still significant.
At $100/barrel, UK drivers can expect to pay roughly 10-15p/litre more than in early 2026. For a driver filling a 50-litre tank weekly, that is around £260-£390 extra per year.
Check tyre pressure. Underinflated tyres reduce fuel economy by 1-3%. On a 30mpg car, keeping tyres properly inflated can save $30-$90/year at current prices. It takes 5 minutes.
Combine trips. Cold engine starts use more fuel. Combining errands into one trip rather than several separate ones cuts fuel use meaningfully for city drivers.
Smooth driving. Hard acceleration and late braking each increase fuel consumption by 15-30%. Smooth, anticipatory driving is the single biggest behavioural fuel saver.
Consider the timing of large purchases. If you are planning to buy a car in the next 12 months, the economics of hybrid and electric vehicles look more compelling at $100+ oil than they did at $72. The payback period for the fuel savings shortens substantially.
US pump price baseline of $3.20/gallon sourced from February 2026 EIA weekly retail data. Pass-through rate of 65% derived from EIA crude-to-pump analysis 2000-2024. UK baseline of approximately 148p/litre (February 2026). UK fuel duty rate of 52.95p/litre (2026). All calculations assume sustained price change. For temporary spikes, actual pass-through may be lower.
