BMW 5 Series: $35,400 of Your Cost Is Just Depreciation
Our calculator puts the 2025 BMW 5 Series at $1,136 a month over five years. Over half is value vanishing. Here is who that math works for.
Our calculator puts Cayenne ownership at $95,144 over five years, $1,586 a month. Depreciation is half of it, and insurance costs more than fuel.

Run the comparison →Our calculator says insuring a 2025 Porsche Cayenne for five years costs $20,233. Fueling it costs $19,011. Most buyers worry about the gas bill on a six-figure SUV. The insurance bill is bigger.
That is the odd little fact in the middle of a larger number: $95,144 to own this car for five years at 12,000 miles a year, or $1,586 a month. We assumed a purchase price of $87,000. That is our estimate for this model year, not a quote from a dealer.
Half of it is depreciation. Our figure is $43,500 over five years, which means the car is worth about $43,500 at the end. You never write a check for that money, which makes it easy to ignore. It is still the largest cost you will have.
The next two lines are the ones that surprise people. Insurance at $20,233 and fuel at $19,011 add up to $39,244. That is close to the whole depreciation bill. Running the car, just feeding and covering it, costs nearly as much as the value it loses.
Then the smaller items:
Repairs are the smallest real expense. That is useful to know, because the usual fear with a German luxury SUV is the surprise repair bill. Our estimate is that the planned costs (insurance, fuel, servicing) are far bigger than the unplanned ones. Maintenance at $6,853 is about $1,371 a year, which is Porsche pricing for oil, brakes, fluids and tires on a heavy, fast vehicle.
Our insurance figure is an estimate built from the car's value and class. It is not a quote. Your age, ZIP code, driving record and insurer will move it, possibly by a lot.
The Cayenne is for people who want a family-sized SUV that drives like it was built by people who like driving. It is the one large SUV where the steering and body control are the point, not an afterthought.
It is for a buyer who can absorb $1,586 a month in true cost without strain, and who will keep the car long enough to enjoy it.
It is not for someone stretching to afford the payment. Add insurance and fuel on top of a loan and the monthly pain is real. It is also not for people who just want a nice third-row family hauler. The Cayenne seats five. If you want a quiet, soft, easy cruiser, there are cheaper ways to get that.
Porsche sells the Cayenne in several versions, plus a Coupe body style. Prices below are approximate starting figures and shift with options and destination fees, so check Porsche's official build page before you decide anything. Our $87,000 assumption is for the entry model.
| Trim | MSRP | What you actually get |
|---|---|---|
| Cayenne | About $87,000 (our assumption) | Turbocharged V6, all-wheel drive, adaptive air-style ride options, the full Cayenne chassis |
| Cayenne E-Hybrid | About $100,000 | Plug-in hybrid with electric-only range for short trips and more power |
| Cayenne S | About $115,000 | Twin-turbo V8, much quicker, a clear step up in sound and speed |
| Cayenne Turbo E-Hybrid | About $185,000 | Supercar-level power from a hybrid V8 setup, and a supercar-level price |
The base car is the sensible pick. It is already quick. The jump to the S buys speed most owners will use on a few on-ramps a year.
The real money trap is the options list. Porsche is famous for charging extra for things other brands include. A base Cayenne can climb by $10,000 or more with wheels, paint, seats and driver aids. If you add that, your depreciation dollar figure rises too, since you lose a share of everything you paid.
The base car uses a turbocharged V6. The S uses a twin-turbo V8. The two hybrids pair a battery and electric motor with a gasoline engine. All are automatic and all-wheel drive.
For official mileage numbers, use the EPA's fueleconomy.gov and compare trim by trim. We would rather talk about dollars. Our calculator puts fuel at $19,011 over five years, which is about $3,800 a year and roughly $317 a month. That is a car that likes premium gas and uses plenty of it.
The plug-in hybrid can beat that number, but only if you really plug it in. A plug-in that never sees an outlet is just a heavier, more complicated gas car.
The driving. That is the main reason to pay Porsche prices. The Cayenne stays flat in corners, steers with real feel, and hides its size better than anything in its class.
The cabin is also well made. Materials feel solid, the seats are supportive on long trips, and the dashboard layout has had a recent update that brings a large digital display. The cargo area is useful for a family that is not hauling a lot.
Repairs and quality look decent in our numbers. At $5,292 over five years, the repair estimate is not scary for a car like this.
The resale story is mixed, though. Half the value gone in five years is normal for an expensive luxury SUV. A Cayenne holds up fine against its rivals, but it does not escape the usual curve.
The price of fairness. Features that mainstream brands include at half the cost often cost extra here. Adaptive cruise, upgraded audio, heated or ventilated seats, and some driver aids can all appear as line items.
The touchscreen-first interior update also drew mixed reactions. Some controls that used to be physical now live on screens, which is worse while driving.
Fuel and insurance are a double hit. Those two lines together cost $39,244 in five years. Few buyers think about that when they sign.
The third problem is the monthly bill. At $1,586 a month all in, this is not a casual purchase, even if the sticker looks manageable.
We could not confirm a full crash-test rating for the 2025 Cayenne. Check NHTSA and the IIHS directly, because ratings are added over time and we would rather say that plainly than guess. Until you see an actual result, treat it as not fully rated. The car does offer a long list of driver assistance features, but some are paid options.
We will use the Cayenne E-Hybrid at roughly $100,000 as the mid-level car.
Add it up and the first year can easily cost more than $25,000 in real money plus lost value. That is a lot before the car is even broken in.
BMW X5: The Cayenne wins on steering feel and handling. The X5 wins on price and on cheaper options.
Mercedes-Benz GLE: The Cayenne is far more fun to drive. The GLE is softer, quieter and plusher for daily commuting.
Audi Q8: The Cayenne has the better driving character and a more cohesive interior. The Q8 costs less and is easier to live with in traffic.
Buy the Cayenne if you love to drive, can afford $1,586 a month in true cost without sweating it, and plan to keep it for several years. It is the best-driving large SUV in its class, and that is worth money to some people.
Skip it if the payment is a stretch, or if you only want a comfortable family SUV. A BMW or Mercedes will give you most of the usefulness for less. And skip the expensive trims unless speed truly matters to you.
Most of all, skip it if you only looked at the purchase price. The sticker is $87,000. The five-year bill is $95,144, and insurance quietly costs more than gas.

Jay built MyTrueCarCost after getting burned by the gap between a car’s sticker price and what it actually cost him to own. He designed the site’s ownership-cost model, which pulls EPA fuel-economy data, RepairPal reliability records, and regional fuel prices to estimate the real five-year cost of a vehicle. Every figure in these guides comes from that calculator.
