Nebraska Gas Prices and Why They Are What They Are
Prices as of July 21, 2026, per AAA · Updated July 21, 2026
As of July 21, 2026, regular gasoline in Nebraska averages $3.90/gallon (the 20th-lowest in the U.S.), per AAA — 0.10 below the national average of $4.00. Diesel averages $4.72. State fuel taxes and fees add 32.7¢/gallon on top of the 18.4¢ federal excise.
Where the $3.90 goes
| Component | $/gallon | Share | Source |
|---|---|---|---|
| Crude oil (national cost, WTI June 2026) | 2.02 | 52% | EIA |
| Federal + Nebraska fuel taxes (18.4¢ + 32.7¢) | 0.51 | 13% | Tax Foundation |
| Refining, distribution, margins & embedded program costs (residual) | 1.37 | 35% | computed |
Crude oil costs every state's refiners roughly the same, so Nebraska's position comes from the tax line and the residual: refining capacity and logistics, fuel-specification requirements, and any carbon or clean-fuel program costs embedded in the pump price.
