Texas consistently has among the lowest gas prices in the United States, typically $0.50-1.50 per gallon less than California. Three factors drive this: a low state gas tax ($0.20/gallon — 5th lowest nationally), proximity to Gulf Coast refineries (Texas refines 30% of US gasoline), and competitive market forces. However, Texans drive more than most Americans — larger cities, suburban sprawl, and 80 mph speed limits mean higher annual mileage. This calculator computes your fuel costs, gas tax burden, and savings compared to high-price states, accounting for Texas's unique driving patterns.

Insight
Driving 250 miles/week at 25 MPG costs $123/month at $2.85/gallon. Texas has one of the lowest gas prices in the US, thanks to a low state gas tax ($0.20/gal — 5th lowest nationally) and proximity to Gulf Coast refineries. You save ~$780/year vs California gas prices. Texas also has NO vehicle emissions testing (except in certain DFW counties) and NO vehicle inspection fee increases. With Texas's large distances between cities (Houston to Dallas = 240 miles), fuel costs are a significant budget item. Consider: many Texans drive trucks/SUVs (lower MPG) — a fuel-efficient vehicle saves significantly.

Frequently Asked Questions
Why is gas so cheap in Texas?
Three main reasons: (1) Low state gas tax at $0.20/gallon (5th lowest in US, vs California's $0.68), (2) proximity to Gulf Coast refineries — Texas refines ~30% of all US gasoline, and (3) competitive market with hundreds of gas stations. Texas also has no cap-and-trade program that adds to fuel costs like California.
What is the Texas gas tax?
$0.20/gallon state tax + $0.184/gallon federal tax = $0.384 total per gallon. Compare: California total ~$0.87/gallon, Pennsylvania ~$0.77/gallon. The Texas gas tax has not been raised since 1991.
How much do Texans drive compared to other states?
Texas drivers average ~15,000-17,000 miles/year — above the national average of 14,263. Sprawling cities, limited public transit, 80 mph highway speed limits, and long distances between cities (Houston to Dallas = 240 miles) all contribute. This means higher total fuel costs despite lower per-gallon prices.
Does Texas have emissions testing?
Only in certain counties. The Texas Vehicle Emission Testing Program applies to vehicles in the DFW area and Houston-Galveston area. Most of Texas has no emissions testing whatsoever. There is no statewide vehicle emissions inspection.
How do electric cars affect gas savings in Texas?
EVs eliminate fuel costs entirely but Texas charges a $200/year EV registration fee to compensate for lost gas tax revenue. At current prices, an EV saves ~$1,500-2,000/year in fuel costs in Texas (less than in California where gas is $5+/gallon). Texas has a growing Supercharger network.
