Gas prices in the U.S. have fluctuated greatly in recent times and many drivers are feeling the pain at the pump.

The cost of rising gas prices is made tougher on average U.S. families by rising inflation. Families had to pay nearly 8% more for average goods and food they needed.

Experts predict gasoline prices could drop below $3 this year before rebounding closer to $4 by year's end. GasBuddy forecasted a national average of $3.38 per gallon, down from $3.51.

Gas data refers to the price of gas when paid for by cash, not credit. Gas stations can charge drivers more for using credit cards due to surcharge fees. This is prohibited in 10 U.S. states.

While data is accurate as of press time, note that gas prices can fluctuate daily or even hourly.
