CX-5 Beats the Outback by $1,127 Over Five Years

The 2020 Mazda CX-5 costs $1,127 less to own over five years than the 2020 Subaru Outback. That works out to about $19 per month. It is not a dramatic gap, but it is consistent, and it comes from a specific place: the Outback costs more to maintain and repair at nearly every point in the ownership window. Fuel costs are identical. Depreciation is identical. Insurance and registration are identical. The only thing separating these two cars over five years is what happens under the hood when something needs fixing.

The CX-5 is the cheaper car to own. Not by a landslide, but by enough to matter, and for reasons that compound as the years go on. If you are on the fence, the numbers nudge you toward the Mazda. But this is not a clean sweep, and the Outback earns its case for a specific kind of buyer. That case comes later.

The Real Gap: It Is All Repairs and Maintenance

When two cars share the same depreciation curve, the same fuel costs, the same insurance, and the same registration fees, the only place left to look is the service center. That is exactly what separates these two.

Over five years, the CX-5 costs $3,630 in maintenance and $2,495 in repairs, for a combined service cost of $6,125.

The Outback costs $3,920 in maintenance and $3,332 in repairs, for a combined service cost of $7,252.

That $1,127 difference is almost entirely explained by that $1,127 gap in service costs. The math is that clean. The Outback is not a bad car. It is just a slightly more expensive one to keep running, and that expense grows over time rather than shrinking.

Five-Year Cost Comparison Table

Cost Category	2020 Mazda CX-5	2020 Subaru Outback
Total Five-Year Cost	$32,099	$33,226
Monthly Average	$535	$554
Fuel (5 yr)	$9,279	$9,279
Maintenance (5 yr)	$3,630	$3,920
Repairs (5 yr)	$2,495	$3,332
Depreciation (5 yr)	$9,240	$9,240
Insurance (5 yr)	$7,200	$7,200
Registration (5 yr)	$255	$255

Every line is the same except two. That tells you something important: this comparison is not about which car holds its value better or which one gets better gas mileage. It is purely about mechanical reliability and scheduled service costs.

Year by Year: When the Outback Falls Behind

In year one, the cost difference is modest. The CX-5 runs $8,021 in total costs; the Outback runs $8,196. A $175 gap. Close enough that you might call it a wash.

By year two, both cars get cheaper as depreciation slows and maintenance cycles reset. But the Outback's repair costs are already climbing faster. The CX-5 shows $277 in year-one repairs versus $370 for the Outback. By year two, that becomes $370 versus $494.

Year three is where the gap starts to feel real. The CX-5 logs $462 in repairs. The Outback logs $617. That is a $155 single-year difference on top of the maintenance gap.

Years four and five are where owning an Outback gets noticeably more expensive. Repair costs hit $802 in year four and $1,049 in year five for the Outback. The CX-5 reaches $601 and $785 over the same stretch. The Outback's five-year repair bill is $837 higher than the CX-5's, and almost all of that gap is earned in the back half of ownership.

If you plan to sell at the three-year mark, the difference is small enough to ignore. If you are holding for five years, the Outback gets progressively more expensive relative to the CX-5 every single year.

Repair Risk: What RepairPal Says

RepairPal rates the 2020 Mazda CX-5 with a reliability score of 4.5 out of 5.0, placing it first in its class among compact SUVs. Average annual repair costs are around $447. Unscheduled repairs, the ones that blindside you, are less frequent and less severe than the class average.

The Subaru Outback scores 3.5 out of 5.0 on the same scale, which RepairPal classifies as average. Annual repair costs run closer to $631. Subaru's boxer engine and all-wheel-drive system are well-regarded for longevity, but the brand has a documented history of head gasket sensitivity on older models and, on newer ones, higher-than-average rates of oil consumption and sensor-related issues.

The Outback is not unreliable in any alarming sense. It will not strand you. But it is statistically more likely than the CX-5 to send you an unexpected bill, and when it does, that bill tends to be larger. The repair cost data in our five-year model reflects exactly that pattern.

For buyers who hate surprises, the CX-5's reliability edge is worth more than the dollar figures suggest. A $500 unexpected repair at the wrong moment can wreck a budget in ways that a predictable $50-per-month ownership cost never will.

Fuel Economy: Same MPG, Same Cost

Both of these vehicles return 28 MPG combined in their base all-wheel-drive configurations. The CX-5 AWD is rated 27 city / 33 highway, and the Outback AWD comes in at 26 city / 33 highway. For most real-world driving, these numbers are effectively the same.

That is why both cars show identical fuel costs in our model: $1,783 in year one, rising to $1,930 by year five as fuel prices trend upward. The monthly fuel average is about $149 for both. Fuel is not your deciding factor here. Do not let anyone sell you one of these over the other based on gas mileage, because there is no meaningful difference.

Who Should Buy the CX-5

Buy the CX-5 if you keep cars longer than three years and you want predictable costs. The Mazda's maintenance schedule is straightforward, its repair history is cleaner, and its total five-year bill is lower. It rewards owners who hold on.

The CX-5 also makes more sense if you are budget-sensitive on a month-to-month basis. At $535 per month versus $554, the gap is small, but it compounds. Over 60 months, you keep $1,127 that the Outback owner does not.

The interior is slightly tighter than the Outback's, and cargo space is not the CX-5's strong suit. If that does not bother you, there is no financial reason to choose the Outback.

Who Should Buy the Outback

Buy the Outback if you haul gear, carry passengers regularly, or spend meaningful time on rough roads. The Outback has more cargo room, more ground clearance (8.7 inches versus 8.5 on the CX-5), and a longer wheelbase that makes a real difference on long highway trips with adults in the back seat.

The Outback also has a larger community of long-term owners who swear by them. Anecdotally, and backed by Subaru's repair data at higher mileages, the Outback tends to keep running well past 200,000 miles when properly maintained. If you are buying one of these at 55,000 miles and planning to drive it to 200,000, the five-year window in our model tells only part of the story.

Pay the extra $19 per month if the Outback's space and ground clearance matter to your life. Just go in knowing you are paying for those things, not getting a free upgrade.

The Bottom Line

The CX-5 wins this comparison on cost. Not dramatically, but clearly. The entire gap comes down to lower maintenance and repair expenses, and that gap widens every year you hold the car. The fuel costs are identical. The depreciation is identical. The CX-5 just costs less to keep running.

The Outback is not a bad choice. It is a more expensive one. Know what you are buying and why. If space and capability justify the premium, fine. If you are choosing based on cost alone, the CX-5 is the answer.
