Infiniti Ownership Cost Hub 2026

Infiniti at a glance

Our dataset covers 5 Infiniti models spanning Sedan, SUV body styles. The lineup starts at about $40,000 and reaches roughly $85,000 at the top trim, with an average starting price near $50,200. The lineup is built around conventional gasoline powertrains.

What a Infiniti costs, cheapest to priciest

Sticker price is only the starting point, but it sets the floor for sales tax, insurance, and depreciation. The QX50 is the most affordable entry point at about $40,000, while the QX80 tops the range at roughly $85,000 in its highest trim.

Most fuel-efficient Infiniti models

Running costs are a large part of ownership, and efficiency varies widely within a single brand. Based on EPA figures in our dataset, the most efficient Infiniti models are:

• QX50 — 26 MPG combined · most efficient in the lineup
• QX55 — 25 MPG combined
• Q50 — 23 MPG combined
• QX60 — 23 MPG combined
• QX80 — 16 MPG combined

How to compare Infiniti models on total cost

Two Infiniti models with similar sticker prices can differ by thousands of dollars over five years once you add fuel or electricity, insurance, maintenance, and depreciation. Use the cost-of-ownership calculator on any model page to see a pre-filled five-year total based on real EPA efficiency and segment-average depreciation. Infiniti is a premium marque, and premium vehicles typically lose value more quickly than mainstream brands — depreciation is usually the single largest ownership cost, so it deserves close attention.

You can also model financing directly with our Auto Loan Calculator and compare running costs across brands on the full vehicle directory.

What a Infiniti costs to own over five years

Sticker price and ownership cost are different numbers. Running our standard ownership model over 3 representative Infiniti models — the cheapest in the lineup, a mid-range pick, and the most expensive — gives a five-year net cost between $67,898 and $99,385, or roughly $13,580 to $19,877 a year. Net cost means everything you pay out — down payment, loan payments, fuel or electricity, insurance, maintenance and registration — minus the vehicle's projected value at the end of year five.

Assumptions: 12,000 miles a year, 20% down, a 5-year loan at 6.39% APR, 7% sales tax and $150 registration (national baselines), gasoline at $4.06 a gallon (AAA) and electricity at $0.16 a kWh (EIA), plus segment-average insurance, maintenance and depreciation. The projection also uses segment-average depreciation curves, so it is an estimate for a typical Infiniti in that class rather than a forecast for one specific car. Every input is editable on the model pages and in our total cost of ownership calculator.

Depreciation is normally the largest single line. On the QX50, the model above projects roughly $26,220 of value lost over five years — about 57% of its $46,000 price — which is why a low sticker price and a low ownership cost are not the same thing.

How Infiniti compares across our 32-brand dataset

Price position is easier to judge against the whole market than in isolation. Across the 32 brands and 300 models in our dataset, Infiniti ranks 16th on entry price at $40,000 for the QX50, and 11th on top-trim price at $85,000 for the QX80. Ranks are counted from the cheapest end (1st = lowest entry price; ties share a rank) and the median entry price across the dataset is $38,000.

Efficiency sets the floor under running costs. The most efficient Infiniti in our dataset is the QX50 at 26 MPG combined, which ranks 1818th of 244 gasoline, hybrid and plug-in hybrid models. Note that MPGe and MPG use different scales, so electric models are ranked only against other electric models.

None of the 5 Infiniti models in our dataset is battery-electric, against 56 of 300 models (19%) across the whole dataset.
