The True Cost of Owning a Porsche 911 Carrera

Cost example updated October 24, 2026

Start with the price you will actually pay

For a representative example, use a 2025 Porsche 911 Carrera coupe with the 8-speed PDK automatic at $122,095, with the 3.0-liter twin-turbo flat-six (388 horsepower, rear-wheel drive). That is Kelley Blue Book’s starting price for the Carrera, and KBB states that figure includes the $1,995 destination charge (the delivery fee from the factory to the dealer). Edmunds lists the same $122,095 MSRP for the Carrera. One source of confusion, stated rather than hidden: some outlets quote $120,100, which is the same car before destination, $120,100 plus $1,995 is $122,095, so the two figures agree once destination is accounted for. The catch with any 911 is options: Porsche’s list runs long, and a lightly optioned Carrera climbs past this starting point fast, so replace this figure with a written quote for the exact car you are considering.

The down payment does not make the 911 cheaper; it changes how much you finance (borrow). With 10% down ($12,210), 8% APR (the yearly interest rate on the loan) and 60 months, and the 7% sales tax ($8,547) and $900 in title and dealer fees rolled into the loan, this example finances $119,332 at $2,420 a month, and the loan costs about $25,845 in interest over five years.

Fuel: strong mileage, premium price

The base Carrera coupe is rated 21 mpg combined (18 city, 25 highway), good for a sports car, and the reason the fuel line is not the scary one here. At 12,000 miles a year that is about 571 gallons annually, roughly $2,971 a year, $14,857 over five years at $5.20 a gallon. That price matters: the 911 requires premium gasoline, and $5.20 is the AAA national average premium price as of October 24, 2026, not regular gas, which averaged $4.30 the same day. Using the regular price would understate five years of fuel by about $2,571, so do not swap it in. Real-world results move with driving style: a 911 driven hard drinks more than the rating. The method behind that math is in the EV vs. gas guide: miles divided by mpg, times price, times years.

Depreciation is the surprise, it is small

Depreciation is the value a vehicle loses over time, and on most cars it is the biggest cost. On the 911 it is the opposite story. iSeeCars’ 2026 study puts the 911’s five-year value loss at about 11.1%, it keeps roughly 88.9% of its price, the second-best retention in the study behind only the Porsche 718 Cayman. On a $122,095 purchase, that means a resale value near $108,542 after five years, about $13,553 of depreciation, roughly $226 a month. That is why the monthly true cost ($1,487) sits far below the loan payment ($2,420): most of each payment is principal that comes back to you at sale time, not money lost.

Two conflicts, stated rather than settled: a CarBuzz piece citing iSeeCars puts the 911’s five-year loss at 17.1%, and a RoadEthos comparison using iSeeCars’ 2026 study puts the 2026 Carrera at 19.3%, $23,564 of depreciation on this price, about $10,011 worse than the page figure. A separate CarEdge-based report puts the range at 17–20%. Part of the spread is that the 11.1% study figure averages the whole 911 range (including limited, high-demand variants) rather than the base Carrera alone, and iSeeCars’ own study dollar figure ($15,533 average loss) implies a higher average starting price than this base Carrera. Edmunds’ own True Cost to Own page for the 2026 Carrera shows a far larger depreciation figure ($92,575) that does not square with any of the above and is not used here. That is exactly why the resale figure here is a planning assumption, not a forecast: run a second scenario with resale 10% lower so the decision does not depend on an optimistic used market.

Insurance runs sports-car money

Full-coverage averages for a 911 cluster between about $227 and $356 a month depending on the source (Compare.com at the low end, MoneyGeek at about $297, InsuredBetter at about $300, and a TorqBull compilation at about $356). This example uses $300 a month, or $18,000 over five years, inside that published range, near the middle. Premiums depend heavily on the driver, ZIP code, coverage and insurer, so get a quote on the exact trim with matching deductibles (what you pay first on a claim) and limits before treating any average as yours.

911 maintenance costs: everything is Porsche-priced

RepairPal puts 911 repair and maintenance costs near $1,072 a year on average, and rates the 911 2.0 out of 5 for reliability, repair visits are about average in frequency, but when something goes wrong it is more likely to be a big bill than on an ordinary car. A separate Porsche-wide figure puts 10-year maintenance and repair costs near $22,075, or roughly $2,200 a year, and independent-shop guides put routine years at $1,000–$2,500 with major-service years higher. This example allows $1,500 a year, or $7,500 all-in for maintenance and repairs, above the RepairPal average to cover routine service, wear items and a share of the big-ticket years, and labeled here as an allowance, not a published total. Porsche services the 911 on a 10,000-mile or one-year interval, and performance tires wear faster than ordinary tires, so a set of tires inside five years belongs in the plan at 60,000 miles.

The cushion matters most after the warranty years: the 911 carries a 4-year/50,000-mile basic warranty, so year five is the first year fully outside it. Budget for that now, while the car is new.

The full five-year example

Every figure below comes from the site’s own calculator math. The stated inputs are: 2025 Porsche 911 Carrera coupe (PDK), $122,095 price, 10% down ($12,210), 8% APR, 60 months, 7% sales tax, $900 in title and dealer fees, 12,000 miles per year, 21 mpg, $5.20 per gallon premium, $300 per month insurance, $1,500 per year maintenance, $108,542 resale value after five years. The sales tax and fees are rolled into the loan, so the amount financed is $119,332.

• Depreciation: $13,553 ($122,095 minus $108,542 resale)
• Insurance: $18,000 ($300 x 60 months)
• Fuel: $14,857 (12,000 / 21 x $5.20 x 5 years)
• Maintenance: $7,500 ($1,500 x 5 years)
• Tax, fees and interest: $35,292 ($8,547 sales tax, $900 fees, $25,845 loan interest)

That totals roughly $89,202, or about $1,487 a month. Notice what that says about the $2,420 payment: on this car the payment is not the whole story in the other direction, it is about 163% of the average month’s true cost, because most of the payment is principal you get back when you sell. During the loan years the cash actually going out is much higher, payment plus insurance, fuel and upkeep, about $3,093 a month, and the true-cost figure only looks lower because it counts depreciation instead of principal.

Formula

The five-year total is the sum of five buckets: depreciation, insurance, fuel, maintenance, and tax, fees and interest. Depreciation is the $122,095 price minus the $108,542 resale value after five years, which is $13,553. Insurance is $300 a month times 60 months, which is $18,000. Fuel is 12,000 miles a year divided by 21 miles per gallon, times $5.20 a gallon for premium, times 5 years, which is about $14,857. Maintenance is $1,500 a year times 5 years, which is $7,500. Tax, fees and interest is 7% sales tax on $122,095, which is $8,547, plus $900 in title and dealer fees, plus about $25,845 of loan interest, which is $35,292.

Added together, $13,553 plus $18,000 plus $14,857 plus $7,500 plus $35,292 equals $89,202, or about $1,487 a month. The amount financed is the $122,095 price plus $8,547 sales tax plus $900 in fees, minus the $12,210 down payment, which is $119,332. The tax and fees are rolled into the loan. At 8% APR over 60 months, the payment on $119,332 is $2,420 a month, and the loan costs about $25,845 in interest over five years. Most of each payment is principal that comes back to you at sale time, not money lost, which is why the $2,420 payment sits above the $1,487 monthly true cost.

Why 911 buyers should think past year five

Sports cars like the 911 are often keepers, and that is where the economics can improve further: the loan ends at year five, and the depreciation curve is already flat. The costs that arrive in years six through ten are the wear-and-repair years noted above, plus the major services (including the PDK service at 60,000 miles) that fall outside the new-car window. The keep it 10 years guide shows how to extend this same math honestly.

Calculation transparency

Jurisdiction. United States. Sales tax, titling, registration and insurance rules are set by your state, so your exact numbers depend on where you buy and register the car. The 7% sales tax and $900 in fees in this example are planning figures, not any one state's actual rates.

Rules and time period. Five years, 12,000 miles a year, premium gas at $5.20 a gallon (AAA national average for premium, October 24, 2026), 8% APR, 60 months, 10% down. The resale value is a planning assumption, not a forecast.

Scope and limitations. Educational estimate only. Insurance and maintenance are planning figures, not quotes. Get a real quote for the same trim, coverage and loan before you decide.

Sources disagree on the 911's five-year value loss: iSeeCars' 2026 study puts it at 11.1 percent while a CarBuzz piece citing iSeeCars puts it at 17.1 percent, a RoadEthos comparison using the same study puts the 2026 Carrera at 19.3 percent, or $23,564 of depreciation, and a CarEdge-based report puts the range at 17 to 20 percent, so the 11.1 percent figure used here is kept as a planning assumption, not as a current reading. The 11.1 percent figure averages the whole 911 range rather than the base Carrera alone, and Edmunds' True Cost to Own page shows a far larger depreciation figure that does not square with any of the above and is not used here. The $227 a month low end of the insurance range, attributed on this page to Compare.com, could not be verified there; MoneyGeek's $297 a month and Insuraviz's $287 a month are verified.

Questions people actually ask

How much does a Porsche 911 Carrera cost per month?

About $1,487 a month over five years in the example on this page. The loan payment alone is $2,420 a month, higher than the monthly true cost, because most of each payment is principal that comes back as resale value when you sell. Insurance, fuel and upkeep sit on top of that during the loan years, and depreciation is the value the car loses rather than cash out the door.

How much does a Porsche 911 Carrera cost to own for 5 years?

About $89,202 over five years for a 2025 Carrera coupe at $122,095, using the assumptions on this page: 10% down, 8% APR, 60 months, 7% sales tax, 12,000 miles a year and $5.20-a-gallon premium gas.

What is the gas mileage of a Porsche 911 Carrera?

The base 2025 Carrera coupe with the 8-speed PDK automatic is rated 21 mpg combined (18 city, 25 highway), and it requires premium gasoline.

How much does insurance cost for a Porsche 911 Carrera?

Published full-coverage averages range from about $227 to $356 a month depending on the source. This example uses $300 a month, or $18,000 over five years. Your own quote depends on the driver, ZIP code, coverage and insurer.

Does a Porsche 911 Carrera hold its value?

Unusually well, by the best-known study: iSeeCars’ 2026 study puts the five-year loss at 11.1%, meaning the car keeps about 88.9% of its price, though other published figures run higher, from 17.1% to 19.3%, so treat any of these figures as an estimate, not a promise.
