2021 Subaru Outback: True Cost of Ownership (5-Year Breakdown)
The 2021 Subaru Outback is a rugged, all-wheel-drive wagon-SUV crossover that blends car-like fuel efficiency with genuine off-road capability and a spacious interior. At around $23,500 used, it sits in a sweet spot for families, outdoor enthusiasts, and commuters in snow-prone regions who want reliability without full SUV running costs. Subaru's reputation for longevity and strong resale value makes this generation a particularly compelling used-market pick.
Monthly cost breakdown
The 2021 Outback retains value exceptionally well for its segment, typically losing only 35–40% of its original MSRP over five years compared to an industry average closer to 50%, largely due to Subaru's loyal fanbase and strong AWD demand in northern and mountain states.
Pros
- Strong resale value keeps depreciation costs below average for the segment
- Standard symmetrical AWD eliminates the need for costly aftermarket traction upgrades in winter climates
- EPA-rated 26 city / 33 highway mpg on the base 2.5L engine keeps fuel costs moderate versus comparable SUVs
- Subaru's recommended maintenance schedule is straightforward, with 6-month/6,000-mile intervals that are affordable at independent shops
Cons
- All-wheel drive increases tire wear and replacement costs — expect all-season or winter tire sets every 40,000–50,000 miles at $600–$900 per set
- Insurance runs slightly higher than front-wheel-drive competitors due to AWD complexity and repair costs
- Oil consumption on some engines means ongoing monitoring and top-offs add minor but real running costs
- Windshield replacements are pricier than average due to EyeSight recalibration requirements, averaging $500–$700 versus $200–$300 for non-ADAS vehicles
Common problems to watch for
- Oil consumption between changes — some 2.5L FB25D engines consume up to 1 quart per 1,200 miles, so check levels regularly
- Head gasket stress is less common on this generation than older Subarus but still worth monitoring with a coolant pressure test at purchase
- EyeSight driver-assist cameras can require recalibration after windshield replacement, adding $300–$500 to glass repair costs
- CVT transmission fluid should be changed every 30,000 miles despite Subaru's 'lifetime fluid' claim — neglect leads to shudder and costly repairs
- Infotainment system (StarLink) is known for occasional freezing and sluggish response, though this is a comfort issue rather than a mechanical one
The verdict
Cost-of-ownership on the 2021 Outback is genuinely competitive at roughly $712 per month all-in when purchased around $23,500, sitting comfortably below comparable AWD SUVs like the Honda CR-V AWD or Toyota RAV4 AWD at similar price points. Its strong depreciation curve means you'll recover more at resale, partially offsetting the higher-than-average insurance and tire costs. If you verify oil consumption and EyeSight calibration status before purchase, this is one of the smarter used-vehicle buys in the $23,000–$26,000 market.
Best for: The 2021 Outback is ideal for a buyer in a snowy or mountainous region who drives 10,000–15,000 miles per year, wants a practical family hauler with solid resale value, and prefers the driving dynamics of a car over a tall SUV.

Frequently asked questions
How reliable is the 2021 Subaru Outback long-term?
The 2021 Outback uses the revised FB25D engine which improved on older head gasket issues, and many examples reach 200,000+ miles with proper maintenance. Regular oil level checks and timely CVT fluid changes are the two most important habits for long-term reliability.
What is the average insurance cost for a 2021 Subaru Outback?
National average full-coverage insurance for a 2021 Outback runs approximately $1,500–$1,800 per year (~$125–$150/month), though this varies significantly by driver age, location, and driving history.
Does the 2021 Subaru Outback have good gas mileage?
Yes — the base 2.5L engine is EPA-rated at 26 mpg city and 33 mpg highway, or about 29 mpg combined, which is strong for a standard AWD crossover and helps keep monthly fuel costs around $150 at 12,000 miles per year.
What are the most expensive repairs to watch out for on the 2021 Outback?
CVT transmission replacement is the costliest potential repair at $3,500–$5,000, but it's largely avoidable with fluid changes every 30,000 miles. EyeSight windshield recalibration ($300–$500) is the most common unexpected expense owners encounter.
How much does the 2021 Subaru Outback depreciate?
Starting from an original MSRP of roughly $27,000–$31,000, a used example at $23,500 has already absorbed the steepest early depreciation. Over the next five years of ownership from this purchase point, expect it to lose another $10,000–$12,000 in value, or about $200–$245 per month — well below segment average.
Is it better to buy or lease a 2021 Subaru Outback?
At this price point you're buying used, so leasing isn't applicable — and buying is clearly advantageous here since the Outback's strong residual value means you'll recoup a meaningful portion of your purchase price at resale after five years.
