Auto tariffs are squeezing rental fleet costs in 2026
Tariffs and a normalising used-car market are pushing rental fleet costs up while rates soften. Here's what the 2026 squeeze means for small operators — and how to protect your margin.
For most of the last few years, the cheapest part of running a rental fleet was the cars. Buy low, run them hard, sell them into a hot used-car market, repeat. In 2026 that maths is changing. Tariffs have lifted the cost of new vehicles, the used-car windfall that padded everyone’s books is fading, and rental rates aren’t rising fast enough to cover the gap. If you run a small fleet, this is the squeeze to plan around this year.
The tariff that reset fleet maths
In April 2025 the United States put a 25% tariff on imported vehicles, effective 3 April, ending decades of duty-free North American trade. Cox Automotive estimated the measure would push prices higher by an average of about $5,300 per vehicle, and warned that new and used prices would rise while some affordable models could disappear from the line-up entirely (Cox Automotive).
That matters to rental operators more than to almost anyone, because the affordable sedans and compact SUVs that make up the backbone of a sensible fleet are exactly the imported, price-sensitive models the tariff hits hardest. The American Car Rental Association warned that the duties threaten to tighten supply and raise costs across the rental industry (ACRA).
Buying new just got more expensive
The headline number tells the story: by late 2025 the average new-vehicle transaction price was holding near $50,000 (Cox Automotive). For a small operator deciding whether to add a car, every thousand dollars on the sticker is real money you have to earn back in rental days before the vehicle makes a cent.
The fleet majors have responded by simply buying fewer cars. New rental-vehicle sales were down roughly 5% year over year, with quarterly fleet purchases off about 4% and April 2026 purchases down close to 10% (Auto Rental News). That restraint protects their pricing power — but it also means fewer late-model cars cycling into the used market, which is where small operators often shop.
The used-car cushion is fading
For three or four years, rental firms quietly made money on the back end: they bought cars, ran them, and sold them for more than expected into a supply-starved used market. That cushion is normalising. Analyst John Healy noted that off-lease supply could grow 15% to 20% a year over the next several years as pandemic-era disruptions wash through — and cautioned that “everyone’s fleet costs have been a bright spot… I think it suggests there is a normalisation coming” (Auto Rental News).
Translation: don’t budget for last year’s resale values. The car you buy in 2026 may be worth less, relative to what you paid, than the one you bought in 2023. That changes your true cost per day — the single number every rental decision should run through. We break that calculation down in how to price your car rental fleet.
Rates aren’t keeping up
Here’s the painful part: while costs climb, rental prices are softening. Market data for early 2026 showed average booking values falling — around €438 in February, down roughly 5% year on year — as demand rose but pricing moderated from its post-pandemic peak (Aviation.Direct). Higher cost per car, flat-to-lower revenue per day. That is the definition of a margin squeeze, and it lands on small fleets just as it does on the chains.
What it means for a small fleet
You can’t control tariffs or the used-car cycle. You can control how exposed you are to them:
- Hold your cars longer. If new vehicles cost more and depreciate more slowly, the case for keeping a reliable car an extra season — instead of churning the fleet — gets stronger.
- Buy to demand, not ambition. An over-bought fleet in a softer-rate year is the fastest way to turn a tariff into a loss. Match purchases to the days you can actually fill.
- Know your cost per car. Finance, insurance, maintenance and a realistic resale value — per vehicle. If you don’t track it, you can’t tell which cars still earn. See how to choose the right cars for your fleet.
- Defend utilisation. When the asset costs more, idle days hurt more. High utilisation is the cheapest margin you have.
- Shop the used market deliberately. More off-lease supply is coming. Patient operators who buy well-kept, in-demand models can sidestep the worst of the new-car premium.
The wider picture — softer demand, smarter pricing, an online-first customer — is in our 2026 industry outlook. The fleet-cost squeeze is one more reason the winners this year will be the operators who treat every car as a P&L line, not a trophy.
