How Rising Gas Prices Affect Small Businesses in 2026

On March 5, Marcus Rivera noticed his weekly fuel bill for his four-truck landscaping company in suburban Dallas had jumped from $1,200 to $1,800. That was before diesel crossed the $5 mark. “I’m eating $600 a week I didn’t budget for,” Rivera told CNN Business. “That’s $2,400 a month that comes straight out of my margin.” He’s one of millions of small business owners watching the Iran war push gas prices to their highest levels since 2023, with no clear end date.

Rising gas prices affect small businesses through higher transportation costs, increased cost of goods, reduced consumer spending, and squeezed profit margins. In March 2026, the national average for regular gasoline hit $3.79 per gallon, up nearly 80 cents from a month ago. Diesel, the fuel that moves nearly every product in America, crossed $5.04 per gallon for the first time since 2022.

The cause is specific: the U.S.-Israeli strikes on Iran that began on March 1 have disrupted traffic through the Strait of Hormuz, where roughly a third of the world’s seaborne oil exports passed through in 2025. Brent crude briefly touched $119 per barrel this week. For small business owners, this isn’t an abstract geopolitical event. It’s a line item that’s growing every week.

How do rising gas prices affect small businesses?

The damage works through four channels, and most small businesses are exposed to all of them simultaneously.

Direct fuel costs. Any business that operates vehicles feels it first. Delivery services, contractors, landscapers, mobile service providers, food trucks, and field sales teams are burning through budgets that were set when gas was $2.90 a gallon. A business running 10 vehicles that each use 15 gallons a day is now spending an extra $135 per day compared to a month ago. That’s over $3,500 per month in unplanned costs.

Supplier price increases. Even if your business doesn’t own a single vehicle, you’re still paying for fuel. Diesel powers the trucks that deliver your inventory, the ships that carry your raw materials, and the farm equipment that grows your food. Higher diesel prices have an inflationary effect on nearly every product in the economy. Multiple vendors are already passing through fuel surcharges, and more will follow.

Reduced consumer spending. When people pay more at the pump, they spend less everywhere else. A 2026 CNBC analysis described the dynamic as a “K-shaped economy” where rising fuel costs act as a regressive tax, hitting lower-income consumers hardest. For small businesses that depend on discretionary spending, like restaurants, salons, and retail shops, the effect is a quiet drop in foot traffic and average ticket size.

Employee costs. Workers with long commutes are asking for raises, requesting remote work, or leaving for jobs closer to home. Gig workers are especially exposed: some Uber and DoorDash drivers estimate that as much as 60% of their earnings now go to fuel and vehicle expenses. Lyft responded by adding a 55-cent fuel surcharge per ride, but critics say that doesn’t cover the real cost increase.

What should small businesses do about rising gas prices right now?

The businesses that survive cost spikes are the ones that act in the first 30 days, not the ones that wait and hope prices come back down. Here’s a practical playbook organized by urgency.

This week: audit and communicate

Start by isolating your fuel exposure. Create a separate sub-account or tracking category for fuel costs so you can see the exact number, not a blended estimate buried in “operating expenses.” If you don’t know how much fuel is costing you right now, you can’t make good decisions about what to do about it.

Then communicate with your customers before they notice the price change. Don’t raise prices silently and hope nobody asks. Send a direct email explaining the situation. Raj Bhaskar, CEO of Tight, put it well in CPA Practice Advisor: “You don’t have to apologize for keeping your business profitable during a global crisis. You just have to bring your customers along for the ride.” Customers are paying $3.79 at the pump too. They understand.

This month: restructure operations

Implement fuel surcharges, not permanent price hikes. A separate, temporary line item on invoices labeled “fuel surcharge” works better than rolling fuel costs into base pricing. It signals the increase is tied to external conditions and will adjust when prices normalize. Service businesses, delivery companies, and contractors should add this immediately.

Consolidate shipments and deliveries. If you’re receiving three small vendor deliveries per week, negotiate to consolidate them into one larger shipment. If you’re making daily deliveries to customers, switch to a zone-based schedule where you deliver to specific neighborhoods on specific days. Grouping stops by ZIP code instead of chronological order reduces miles driven by 15-20%.

Shrink your delivery radius or add tiered pricing. Offer free delivery within 10 miles and charge a transparent fuel-based fee beyond that. Some businesses are incentivizing customer pickups with a 5% discount or a free item, which eliminates vehicle trips entirely.

This quarter: invest in efficiency

Route optimization software pays for itself fast. Companies deploying route optimization solutions report fuel savings of 20-30% within the first 90 days. For a 10-vehicle fleet spending $8,000 monthly on fuel, that translates to roughly $24,000 in annual savings. Tools like Upper, OptimoRoute, and Zeo Route Planner cost $2,000-$8,000 annually for a 10-driver fleet, delivering 10x to 50x ROI in the first year.

Review every contract with a fuel clause. If your client contracts don’t include a provision for adjusting rates based on fuel costs, add one to every new contract going forward. For existing contracts, reach out to renegotiate. Most clients will agree to a reasonable adjustment when presented with the actual cost data.

Evaluate fleet electrification ROI. A used electric delivery van costs $25,000-$40,000 and runs on roughly $0.04 per mile in electricity versus $0.25-$0.35 per mile for a gas vehicle at current prices. For high-mileage fleets, the payback period has shortened considerably. The federal tax credit of up to $7,500 for new EVs still applies in 2026.

How long will gas prices stay high in 2026?

Nobody knows when the Iran war will end or when the Strait of Hormuz will reopen to normal tanker traffic. But the scenarios are worth understanding so you can plan for each one.

If the conflict ends within weeks and Hormuz reopens, analysts at CNBC project gas prices could settle back to the $3.00-$3.30 range by late summer. Oil infrastructure takes time to repair and shipping routes take time to normalize, so even a quick resolution means elevated prices for 2-3 months.

If the conflict drags through spring and summer with Hormuz partially or fully blocked, the EIA’s March forecast models gas reaching $4.50-$5.00 per gallon nationally, with diesel potentially hitting $6.00. At that level, the trucking industry faces a “crisis within a crisis” according to Commercial Carrier Journal, and supply chain costs cascade through every consumer product.

The worst-case scenario involves damage to Iranian oil facilities that takes years to rebuild. In that case, global oil supply permanently decreases by 3-4 million barrels per day, and $5-$6 gas becomes a structural reality rather than a spike. If you’re making contingency plans, plan for the middle scenario and prepare to adapt if prices stabilize faster or climb higher.

Which businesses get hit hardest by gas price spikes?

Not every business feels the pain equally. The impact depends on how fuel-dependent your operating model is.

Delivery and logistics businesses take the most direct hit. A local courier service running 20 vehicles at 100 miles per day per vehicle burns roughly 100 extra gallons per week at current price levels compared to February. At a $1.00/gallon increase, that’s $400-$500 per week in unplanned costs before a single new customer is acquired.

Mobile service providers like plumbers, electricians, HVAC technicians, and landscapers face a double bind. They can’t reduce driving because the driving IS the work. A plumber making eight house calls per day across a 30-mile radius spends an extra $15-$25 daily just getting to jobs. Over a month, that’s $300-$500 per technician, and most of these businesses run 3-10 trucks.

Restaurants and food businesses absorb gas prices from multiple directions. Ingredient delivery costs rise because food distributors add fuel surcharges. Delivery app orders become less profitable as driver shortages increase. And customers, spending more at the pump, spend less eating out. The National Restaurant Association reported that 62% of restaurant operators said higher gas prices reduced customer traffic during the 2022 diesel spike, and this one is tracking worse.

E-commerce and shipping-dependent businesses face carrier surcharges. UPS, FedEx, and USPS all adjust fuel surcharges weekly based on the DOE diesel index. When diesel jumped from $4.00 to $5.04, the fuel surcharge on a standard ground shipment increased by approximately 2-3 percentage points. For a business shipping 500 packages per month at $10 average shipping cost, that’s an extra $100-$150 monthly that either eats margin or gets passed to buyers.

Should I raise my prices because of gas costs?

Yes, but the how matters more than the whether. The businesses handling this well are being transparent, specific, and temporary in their approach.

A fuel surcharge of 3-8% is within the range most customers will accept without pushback, especially when you explain the math. Show your customers the before-and-after: “Our fuel costs went from $X to $Y per month. We’re adding a temporary 5% fuel surcharge to cover the difference, and we’ll remove it when pump prices drop below $3.25.” Specificity builds trust.

For multi-location businesses or franchises, consider absorbing the cost in your highest-margin locations while passing it through in lower-margin ones. This protects the locations most vulnerable to customer loss while keeping overall company margins stable. If you operate in a competitive market where competitors haven’t raised prices yet, frame your surcharge as temporary and honest rather than trying to match their pricing by cutting corners elsewhere.

The businesses that lose customers are the ones that raise prices 15-20% without explanation, bundle fuel costs into vague “price adjustments,” or stay silent and let quality slip as they try to absorb costs they can’t afford. According to a Time analysis, businesses that communicated proactively about war-driven cost increases retained customers at significantly higher rates than those that raised prices without context.
