Gas Prices Continue to Surge in U.S., Rising 14% in a Week
US gas prices are surging at historic rates — up 14% in a single week — as the Iran conflict disrupts global oil supply through the Strait of Hormuz. The national average has climbed past $4.25/gallon with some states seeing $5+. This calculator shows exactly how much more you'll spend on fuel and what you can do about it.
About This Calculator: US Gas Price Surge
Why: US drivers are feeling the pinch as gas prices surge 14% per week. Most people don't know exactly how much more they'll spend or what alternatives could save them. This calculator shows your weekly and monthly surge cost, EV break-even price, and savings from alternative transport.
How: Enter your current gas price, weekly miles, MPG, tank size, fuel type, state, surge duration, and alternative transport option. The calculator applies 14% weekly compounding (capped at 2x), state tax variation, and fuel-type premiums. It computes extra costs, EV break-even, and savings from transit/carpool/WFH.

CalculateIntroduction: The 14% Weekly Gas Surge
US gas prices are surging at historic rates — up 14% in a single week — as the Iran conflict disrupts global oil supply through the Strait of Hormuz. The national average has climbed past $4.25/gallon with California above $5.80. Four key stats: (1) 21% of global petroleum passes through the Strait; (2) crude oil has risen 22% in weeks; (3) diesel is up 18% in the same period; (4) some states see $6+ at the pump.
Key Takeaways
- • The surge could last 2-12 weeks depending on geopolitical resolution
- • State taxes add $0.09-$0.68 per gallon — location matters
- • Alternative transport (WFH, transit, carpool) can cut costs 40-90%
- • EVs save on fuel when gas exceeds ~$1-1.50/gal (fuel-only comparison)
Did You Know? 6 Gas Price Facts
- • California has the highest state gas tax at ~68 cents/gallon
- • Federal gas tax is 18.4 cents/gallon (unchanged since 1993)
- • A barrel of oil yields ~19 gallons of gasoline
- • Every $1/barrel adds ~$0.025/gallon at the pump
- • Premium fuel costs 15-25% more than regular
- • Diesel typically tracks crude more closely than gasoline
How Gas Prices Flow from Crude to Pump
Crude oil is refined into gasoline, then distributed to stations. The pump price breaks down roughly: 55% crude cost, 20% refining, 15% distribution & marketing, 10% taxes. State and federal taxes vary widely. California adds cap-and-trade and low-carbon fuel fees. Distribution costs rise in remote areas. Refining margins spike when capacity is tight.
Expert Tips to Save on Fuel
- • Use GasBuddy or AAA to find the cheapest stations nearby
- • Maintain tire pressure — under-inflation reduces MPG by 3%
- • Consolidate trips — cold starts burn extra fuel
- • Carpool or use public transit for commute days
- • Drive 5 mph slower on highways — can improve MPG 5-10%
State-by-State Gas Prices and Taxes
| State | Tax ($/gal) | Typical Price |
|---|---|---|
| California | $0.68 | $5.80+ |
| Texas | $0.20 | $3.80+ |
| Illinois | $0.67 | $4.50+ |
| Pennsylvania | $0.59 | $4.40+ |
| Florida | $0.39 | $4.00+ |
| Alaska | $0.09 | $3.90+ |
Frequently Asked Questions
Why are US gas prices surging 14% per week?
The Iran conflict has disrupted oil shipments through the Strait of Hormuz, which handles 21% of global petroleum. Supply fears have pushed crude above $95/barrel. Gas prices at the pump typically track crude within days, so the national average has climbed past $4.25/gallon with California above $5.80.
How long will the gas price surge last?
Experts estimate 2-12 weeks depending on geopolitical resolution. The calculator lets you model 2, 4, 8, or 12-week surge durations. Past oil shocks (1973, 2008, 2022) saw elevated prices for months. Planning for 4-8 weeks of higher costs is prudent.
Does my state affect my gas costs?
Yes. State gas taxes vary widely. California has the highest at ~$0.68/gallon; Texas is among the lowest at ~$0.20. Combined with regional refining and distribution costs, drivers in high-tax states pay significantly more. Use the state selector to see your exposure.
When does an EV save money vs gas?
EVs cost roughly $0.03-0.04 per mile in electricity vs $0.12-0.20 for gas cars at current prices. The break-even gas price depends on your car's MPG: at 28 MPG, an EV saves when gas exceeds ~$1.00/gal (fuel-only). With gas at $4+, EVs save hundreds per month on fuel.
What alternative transport saves the most?
Work-from-home eliminates commute fuel entirely. Public transit typically costs $50-150/month vs $200-400 for driving. Carpooling halves your fuel bill. Biking saves 100% of fuel for short trips. The calculator shows weekly savings for each option.
How can I reduce my fuel costs during the surge?
Use GasBuddy to find the cheapest stations, consolidate trips, maintain tire pressure, avoid idling, and consider carpooling or public transit. Premium fuel is rarely worth it unless your car requires it. Driving 5 mph slower on highways can improve MPG by 5-10%.
