To say gas prices have been unpredictable this year would be an understatement.

On Thursday morning, drivers across the U.S. were spending an average of $3.85 per gallon of regular unleaded, according to AAA.

The average cost of a gallon this year peaked in May at $4.56, and plunged as low as $2.79 in January, the organization reported.

Oil prices have spiked around the world in recent months after the U.S. and Israel launched a war on Iran, which has disrupted shipping through the Strait of Hormuz. But the on-and-off hostilities have done more than simply raise gas prices in a straight line — they've caused gas to become more expensive one week, only for the price to fall the next. Prices go up when fighting rekindles or the strait is closed, and drop when peace talks resume. They're climbing again after Trump said the tenuous ceasefire was over.

Now, drivers are unsure of what price they'll find when they pull into a gas station, said Emily Blain, an accredited financial counselor in Minnesota.

"'How bad is it going to be this time? Is it going to be not as bad as I think, or is it going to be worse than I think?'" Blain said. That can contribute to stress, she added, "and since many people are going to the gas pump fairly often, that absolutely adds up."

How volatile prices affect consumer behavior

When it comes to price, gas is one of the more volatile consumer goods. U.S. motor fuel prices jumped as much as 35.8% annually over the last two decades and fell by as much as 27.8% in the same period, according to the USDA's Economic Research Service.

That unpredictability can influence consumers' buying habits — and it's been doing so in recent months.

Data from the cash back app Upside found that when gas prices rose in the first two and a half weeks of March, drivers visited gas stations more often but bought less fuel each time.

"Some drivers can't afford to fill up their tank at a given time, so there's definitely some cash constraints," said Upside principal research economist Thomas Weinandy. Other drivers might be in the habit of spending a set amount on fuel, which now buys less than it did weeks or months earlier, he added. "Someone might be used to just saying, 'put $20 on pump 1,' and they continue that behavior."

When prices fall back down, drivers typically buy more gas per visit, a phenomenon Weinandy says began to appear in the June data.

Experts say that consumers can expect price swings to stick around. Lauren Swift, senior editor for Autotrader and Kelley Blue Book, told NPR over email that historically when "gas prices have seen a sharp uptick due to war or other global conflicts, they take a very long time to come back down, typically years."

What drivers can do

Though changes in the price of gas can often appear minimal, increases can put a dent in household budgets over time. The financial website NerdWallet found that a $0.50-per-gallon spike could cost drivers in some states around $500 more per year.

"There is not much control you have over the prices, so all we can really do is to prepare to pay more at the pump," said Kimberly Palmer, personal finance expert at NerdWallet. But drivers still have a say in what they spend on fuel, she said.

Here are a few strategies consumers can use to deal with fluctuating gas prices:

  • Assume the price will be high, and build that into your budget. "If we plan ahead knowing that gas prices are expected to be higher, then it can be a nice surprise if they end up going down that week," Palmer said. If prices drop instead, you'll have some money left over.
  • Use websites or apps to shop around for the best price. Palmer said driving even a few miles out of your way could be worth it to pay substantially less per gallon.
  • Use less gas. That could mean cutting back on driving, if that's an option for you. It could also mean adopting fuel-saving driving habits, such as driving more smoothly, ensuring your tires are inflated and removing excess weight from your vehicle. You may also consider switching to an electric vehicle, if that's within your budget. Spending less money on gas now gives you a financial cushion should prices rise again later.

For most people, the monthly cost of gas will be dwarfed by other household expenses like housing. But Blain, the financial counselor, said rent increases and property tax hikes typically occur annually and then appear as predictable monthly expenses. Fluctuating expenses, like groceries and gas, are different and can have a more immediate impact on consumers — even if they're a smaller share of your budget.

"You never know what you're going to get, to a certain extent," Blain said. "That feels really uncomfortable regardless of the actual dollar-and-cent impact, which can also be significant at times."
