Silverado vs Sierra: A $23 Gap Hides a $1,727 Fuel Bill

Our calculator puts the 2023 Chevrolet Silverado at $36,511 over five years and the 2022 GMC Sierra at $36,534. That is a $23 gap, and both trucks land at $609 a month. On the bottom line, the Silverado wins by the price of a pizza.

Don't stop at the total, though. The $23 is the result of two big forces canceling each other out. The Sierra costs $1,727 more in fuel, while the Silverado loses $734 more to depreciation and $756 more to repairs. My pick is the Silverado, but only barely, and only if you drive enough for fuel to matter to you.

A tie on paper, two different trucks underneath

Here is the real story. The Silverado starts at an assumed $25,500. The Sierra starts at $24,100. Those are our estimates for each model year, not listings you will see at a dealer. The Silverado is the newer truck and the more expensive one to buy, so it has more value to lose.

That shows up in depreciation. Our calculator has the Silverado losing $6,893 over five years and the Sierra losing $6,159. The Silverado gives up $734 more.

The Sierra gets that money back and then some at the pump. Its fuel bill is $16,419 against $14,692 for the Silverado. That is $1,727 in the Silverado's favor.

So the cheaper-to-buy truck is the thirstier one. The newer, pricier truck burns less. Each one charges you in a different place.

The smaller line items lean toward the Sierra. Repairs run $1,890 for the Sierra and $2,646 for the Silverado, a $756 difference. Maintenance is $3,115 against $3,180, only $65 apart. Insurance is $8,696 for the Sierra and $8,845 for the Silverado, $149 apart. Registration is $255 for both.

Add up who wins each category and the Sierra takes more of them: depreciation, repairs, maintenance and insurance. The Silverado wins on fuel, and fuel is big enough to flip the whole result. Fuel is the largest single cost for both trucks, bigger than depreciation and bigger than insurance.

Fuel is the swing factor

Our calculator puts the Silverado at $245 a month for fuel, averaged over five years. The Sierra is at $274. That is $29 more per month for the Sierra.

$29 does not sound like much. It adds up to $348 a year, and the yearly figures widen as fuel prices climb in our model. In year one the Silverado costs $2,823 for fuel and the Sierra $3,155. By year five it is $3,056 against $3,415.

If you want the miles-per-gallon ratings behind that, check the 2023 Chevrolet Silverado on fueleconomy.gov and the 2022 GMC Sierra on fueleconomy.gov. Trucks come with many engine and drivetrain choices, and the ratings differ a lot between them. Look up the exact configuration of the truck you are buying, not just the model name.

The point is simple. Fuel cost depends on how many miles you drive. If you drive more than our calculator assumes, the Silverado's fuel advantage grows and it pulls further ahead. If you drive less, the Sierra's cheaper purchase and lower repair costs matter more, and it could come out ahead.

How the years play out

Year one favors the Sierra. Our calculator has it at $7,244 against $7,335 for the Silverado, a $91 edge. The Sierra's lower sticker price means less depreciation in the first year: $1,608 against $1,897.

Year two is where both trucks hit a speed bump. The Silverado costs $8,108 and the Sierra $8,116. Both have a big maintenance bill that year: $1,450 for the Silverado and $1,422 for the Sierra. Think of it as the big scheduled service that most trucks need around that point. It is planned, but it hurts.

Year three is the cheap one. The Silverado is $6,867 and the Sierra $6,907. The Silverado is ahead by $40 and has been ahead since year two, in fact, by a hair.

Year four stays close: $6,904 for the Silverado, $6,934 for the Sierra.

Year five flips the other way. The Silverado costs $7,297 and the Sierra $7,333. A $36 gap again, favoring the Silverado.

Look at that pattern. After year one, the Silverado is cheaper in every single year, but never by much. Depreciation slows down on both trucks, which shrinks the Silverado's biggest disadvantage over time. Meanwhile fuel keeps climbing for both. That slow shift is why the Silverado edges ahead.

Neither truck gets dramatically more expensive over time. Both climb in repairs, and both get cheaper in insurance. The Silverado's repair bill goes from $294 in year one to $833 in year five. The Sierra's goes from $210 to $595. Insurance drops on both as the trucks lose value: the Silverado from $1,865 to $1,688, the Sierra from $1,823 to $1,667.

Remember that insurance numbers are our estimate based on each truck's value and class. They are not a quote. Your own rate will depend on your age, your ZIP code and your driving record, and it will differ.

Repair risk: the Sierra looks safer, but not by a lot

Our calculator expects $2,646 in repairs for the Silverado over five years and $1,890 for the Sierra. That is $756 more for the Silverado.

The two trucks are close cousins. They share a lot of mechanical parts, so I would not read too much into that gap. It is a model estimate, and the Sierra's lower value likely plays a part in it.

For independent reliability ratings, check RepairPal for each truck. It reports average repair costs and how often owners visit a shop for unscheduled work. Look at the specific engine you are considering, since full-size trucks vary by powertrain. Pay attention to how often problems show up and how severe they are, not only the average cost.

The repair numbers rise every year on both trucks. In year five the Silverado is at $833 and the Sierra at $595. Neither is a disaster. A single big failure after the warranty ends, such as a transmission or a major electrical fault, could blow past either number. The Silverado carries a bit more exposure in our estimates, though the difference is small compared with the fuel gap.

The one thing I would not do is pick based on repairs alone. A $756 difference spread over five years is about $150 a year. It is real, but it is the smallest of the three big swings.

Why the cheaper truck is not the cheaper deal

The Sierra looks like the bargain at $24,100. It is $1,400 less than the Silverado at purchase. But that discount evaporates. By year five, the Sierra's fuel bill alone has eaten more than the entire purchase price gap.

That is the trap with trucks. A lower sticker price feels like savings, and it is, until you start paying for gas every week. Our calculator shows the Sierra's cheaper start and lower repair costs being wiped out by fuel.

So, is the Silverado a clear winner? No. A $23 difference over five years is a rounding error. Either truck could come out ahead depending on your driving, your local gas prices and what you negotiate at purchase. A $1,400 haggle on the Silverado price would change the result completely.

The verdict

Buy the 2023 Silverado if you drive a lot. If you commute daily, tow on weekends or rack up long highway trips, fuel will dominate your costs. The Silverado saves $29 a month in our model and more if you drive beyond our assumptions. You also get the newer model year. Accept that it loses more value and costs more to fix, and treat the $23 edge as a tiebreaker, not a reason.

Buy the 2022 Sierra if you drive less, or if you can pay less up front. If the truck is a second vehicle, a weekend hauler or a work truck that mostly sits, fuel matters less. Then the Sierra's lower purchase price, lower depreciation ($6,159), lower repairs ($1,890) and lower insurance estimate favor it. It is also the better choice if you can negotiate the price down even further, since it starts cheaper to begin with.

If you cannot say how many miles you will drive, assume you drive a lot and take the Silverado. Fuel is the cost that surprises people, and the Silverado handles it better.

One last point. With a gap this small, you should shop on condition and price, not badge. Get a pre-purchase inspection, check the service history and compare the exact trim and engine. A well-kept Sierra at a good price beats a rough Silverado every time.
