Subaru Ascent Total Cost of Ownership: Fuel, Insurance, and Maintenance on Long Island

The Ascent’s sticker price is one number. What it costs to own and operate on Long Island over five years is a larger, more important number that most buyers don’t calculate before signing. Fuel, insurance, maintenance, and depreciation together typically exceed the purchase price over a full ownership period - and the Ascent’s specifics in each category are worth knowing before you commit.

Bottom Line: The Ascent is a reasonable-cost three-row SUV to own on Long Island when total cost of ownership is calculated. Its depreciation resistance, modest maintenance requirements, and standard AWD without an option premium compare favorably to European and luxury three-row competitors.

• Ascent retains approximately 48-52% of value after five years - competitive for the 3-row segment
• Fuel cost is higher than a Highlander Hybrid but lower than truck-based three-row SUVs
• Annual maintenance averages $500-$700 for the first 60,000 miles on the turbocharged platform

Depreciation on the Ascent

A new Ascent Premium at $40,195 can be expected to retain approximately $19,300-$20,900 in value after five years based on current Ascent depreciation patterns. That represents a loss of roughly $19,300-$20,900 over five years, or approximately $3,860-$4,180 per year.

Three-row SUVs depreciate at a different rate than compact SUVs. The Ascent’s rate is comparable to the Honda Pilot and Toyota Highlander. The Highlander historically holds value slightly better in the Long Island used-car market due to Toyota’s brand strength. The Ascent and Pilot are in a similar tier.

For families who prioritize resale over a five-year ownership window, the Ascent’s depreciation is competitive - particularly for the Premium trim level, which represents the volume of Ascent sales and therefore supports stronger used-car demand.

Fuel Costs on Long Island

The 2026 Ascent returns 21 mpg city and 27 mpg highway on standard trims. The turbocharged engine’s real-world performance in typical mixed Long Island and South Shore driving averages closer to 23-24 mpg for most owners.

At 15,000 miles annually and an estimated combined 23 mpg, the Ascent uses approximately 652 gallons per year. At $3.50/gallon, that’s $2,282 per year in fuel.

This is noticeably higher than the Highlander Hybrid (approximately 36 mpg combined, $1,458 per year) and higher than a compact SUV like the Forester. It is lower than truck-based three-row alternatives like the Ford Explorer or Chevy Traverse at similar mileage.

For Lindenhurst and Bay Shore families who primarily drive on local roads and the Southern State Parkway, real-world fuel costs often improve over EPA estimates due to the lower average speeds. For high-mileage LIE or Meadowbrook commuters, budget closer to the highway figure.

Insurance Costs in Nassau and Suffolk County

A 2026 Ascent Premium in Nassau County carries an estimated annual insurance premium of $2,200-$2,800 for comprehensive and collision coverage with a clean driving record. Suffolk County rates for the same profile typically run $200-$400 lower.

The Ascent insures as a mid-tier three-row SUV - more expensive to insure than a Forester or Outback due to its higher replacement cost and repair complexity, but meaningfully less expensive than European three-row alternatives. The Ascent’s strong IIHS safety ratings support its insurance classification.

Specific factors that affect your Ascent premium in Nassau County:

• Vehicle trim (Limited and Touring cost more to repair, so they insure higher)
• Driver age and record
• Zip code within Nassau or Suffolk County
• Deductible selection and coverage limits

Maintenance Schedule and Costs

The Ascent’s 2.4-liter turbocharged engine introduces one additional maintenance consideration compared to naturally aspirated Subaru engines: turbocharger-specific oil change intervals. Subaru recommends oil changes every 6,000 miles on the Ascent’s FA24 turbocharged engine - consistent with the naturally aspirated models’ intervals.

Average annual maintenance cost across the first five years runs $500-$700 per year when spread across scheduled intervals. The 60,000-mile service is the largest single-visit cost - budget $600-$850 for that service to avoid a financial surprise.

Five-Year Total Cost Summary

For a 2026 Ascent Premium purchased new at $40,195, approximate five-year total cost of ownership:

Depreciation: ~$20,000 | Fuel: ~$11,400 | Insurance: ~$12,500 | Maintenance: ~$3,000 | Total: ~$46,900 over five years, or approximately $781/month in total ownership cost beyond the loan payment.

This positions the Ascent competitively among three-row AWD SUVs. Truck-based three-row alternatives typically run $5,000-$12,000 higher in five-year total cost when fuel and insurance are included.

Total Cost of Ownership FAQ

How does the Ascent compare to the Highlander on five-year ownership cost? The Toyota Highlander standard (non-hybrid) is comparable to the Ascent in total cost. The Highlander Hybrid is meaningfully cheaper on fuel over five years but carries a higher purchase price that partially offsets the fuel savings. Total cost of each depends heavily on annual mileage.

Is the Ascent more expensive to insure than a Forester? Yes. The Ascent’s higher replacement cost and larger vehicle classification result in higher insurance premiums than a Forester or Outback. The difference runs approximately $300-$600 per year in Nassau County, depending on coverage.

What is the biggest maintenance cost to plan for on the Ascent? The 60,000-mile service is the most comprehensive and expensive scheduled interval, covering spark plugs, CVT fluid, and full brake assessment. Planning $600-$850 for that visit is appropriate.

Does towing regularly affect the Ascent’s maintenance costs? Frequent towing increases wear on the engine, transmission, and brakes. If you regularly tow near the Ascent’s 5,000-pound capacity, plan for more frequent oil changes and fluid checks. Subaru’s towing guidelines recommend checking trailer wiring connections and transmission fluid at each towing season.

Should I buy an extended warranty on a new Ascent? For buyers planning to keep the Ascent beyond the 5-year/60,000-mile powertrain warranty, a Subaru factory extended service agreement can provide value. Evaluate the cost versus the average repair frequency for the FA24 engine and CVT combination over the 60,000-100,000-mile range.
