What Costco Prices Could Look Like in 10 Years If Prices Keep Rising

If you think your Costco shopping trips are expensive now, imagine what they’ll cost 10 years from today.

I shop at Costco regularly, and I’ve noticed how quickly my shopping bill adds up.

Nowadays, it’s easy to walk into Costco for a few groceries and leave with a $300 receipt, especially when I start adding prepared meals, snacks, drinks, and a few things I wasn’t planning to buy.

That got me thinking: What would my usual Costco shopping trip cost in 10 years if prices continued rising?

I decided to do the math using some of the groceries I regularly buy at Costco, including milk, eggs, bananas, yogurt, prepared meals, and pantry staples. I also included Costco’s famous $4.99 rotisserie chicken and $1.50 hot dog combo.

For this comparison, I’m assuming prices increase by 4% annually over the next 10 years. This is a hypothetical scenario, not a forecast of actual Costco prices.

Why did I choose 4% inflation? According to an estimate from the Congressional Joint Economic Committee, U.S. consumer prices increased approximately 4.02% over the 12 months ending October 2026. Food prices increased an estimated 3.01% during the same period.

Some of the projected prices really surprised me. Two dozen organic eggs could cost more than $12, a case of Fairlife protein shakes could cost almost $60, and a $300 Costco shopping trip could exceed $444.

Costco Prices in 10 Years

Here’s what a few popular Costco items could cost in 2036 if prices increased by 4% every year.

Costco Item	2026 Price	Projected 2036 Price
Organic eggs, 2 dozen	$8.29	$12.27
Kirkland Ultra-Filtered Milk, 3-pack	$12.59	$18.64
Chicken Alfredo, tray	$18.00	$26.64
Fairlife Protein Shakes, 18-pack	$39.99	$59.19
Executive Membership	$130.00	$192.43

These are hypothetical projections based on a 4% annual price increase over 10 years, not actual future Costco prices. Starting prices may vary by warehouse.

And that’s just five items. Keep reading to see what could happen to Costco’s $1.50 hot dog, $4.99 rotisserie chicken, and other grocery staples.

Everyday Costco Groceries Could Get Much More Expensive

1. Costco’s Ultra-Filtered Milk Could Cost Almost $19

Milk is one of those grocery staples that many families buy every week, which is why even a small price increase can make a difference.

At Costco, Kirkland Signature Ultra-Filtered 2% Milk costs $12.59 for three 64-ounce cartons. That’s 1.5 gallons of milk.

If the price increases by 4% annually, the same three-pack could cost $18.64 in 2036.

That’s an increase of $6.05 per package.

If you buy one package every week, you’d spend approximately $315 more annually at the projected 2036 price.

For something as basic as milk, that’s a pretty significant increase.

2. Two Dozen Costco Organic Eggs Could Cost Over $12

Eggs are another grocery staple whose prices shoppers pay close attention to.

At my Costco, two dozen organic eggs cost $8.29, which works out to approximately $3.45 per dozen.

If prices increase by 4% annually, the same two dozen package could cost $12.27 in 2036.

That’s nearly $4 more per package.

Of course, egg prices can be particularly unpredictable because of factors such as bird flu outbreaks and supply shortages.

So there’s no guarantee prices will increase at a steady rate. They could go up significantly one year and drop the next.

3. Costco Bananas Could Cost Almost $3

Bananas are one of the least expensive things I regularly buy at Costco.

At $1.99 per bunch, they’re an easy addition to my shopping cart. My family eats bananas regularly, and I also use them for smoothies.

But if prices increase by 4% annually, a $1.99 bunch could cost $2.95 in 2036.

That’s almost a dollar more.

While that doesn’t sound like a lot, these small increases add up when you’re buying the same groceries every week.

4. Costco Broccoli Could Cost Almost $12

I buy Costco’s bag of broccoli florets regularly because it’s an easy vegetable to prepare for dinner.

I’ve also started air-frying broccoli, which makes it a convenient side dish without much preparation.

The bag costs $7.99 at my Costco.

At 4% annual inflation, that same bag could cost $11.83 in 2036.

That’s an increase of $3.84.

For families trying to eat more vegetables, increases in fresh produce prices can make weekly grocery shopping more expensive.

5. Costco Chobani Yogurt Could Cost Almost $27

Yogurt is something I buy on almost every Costco shopping trip.

My family eats it regularly, and my son especially likes the flavored Chobani yogurts.

A case of Chobani yogurt costs $17.99 at Costco.

If that price increases by 4% annually, the same package could cost $26.63 in 2036.

That’s an increase of $8.64.

At that price, I’d definitely start looking more closely at sales and comparing the cost with other grocery stores.

6. Kirkland Ancient Grains Granola Could Cost Over $13

Granola is another breakfast staple that can add up over time, especially if your family eats it regularly.

Kirkland Signature Ancient Grains Granola costs $8.89 at Costco.

Under a 4% annual inflation scenario, the same package could cost $13.16 by 2036.

That’s an increase of $4.27.

This is another example of how everyday breakfast foods could become noticeably more expensive over the next decade.

Costco Prepared Meals and Pantry Staples

7. Costco’s Chicken Street Taco Kit Could Cost Over $25

One of my favorite Costco prepared meals is the chicken street taco kit.

I like it because it comes with chicken, tortillas, toppings, and sauce, so I don’t have to buy a bunch of different ingredients to make dinner.

A kit costing $16.99 today would cost approximately $25.15 in 2036 under the 4% annual inflation scenario.

That’s more than $8 extra for the same dinner.

I buy Costco prepared meals for convenience, but if the price rose that much, I would probably start comparing the cost of buying individual ingredients and making the meal myself.

8. Costco’s Chicken Pot Pie Could Cost More Than $35

Costco’s chicken pot pie is another prepared meal I buy, especially when I need something easy to serve for dinner.

The pies are large, and one can feed my family with leftovers.

A chicken pot pie priced at $23.99 today could cost $35.51 by 2036 if prices increased 4% annually.

That’s an increase of $11.52.

At that point, I’d definitely think twice before putting it in my shopping cart.

One thing worth remembering, though, is that Costco’s chicken pot pies are sold by weight. The total price depends on the size of the pie, so this calculation assumes the same size pie in 2036.

9. Costco’s Chicken Alfredo Could Cost Almost $27 Per Tray

Another Costco prepared meal I like buying is the Kirkland Signature Chicken Alfredo.

It’s a convenient dinner because it comes with pasta, chicken, and Alfredo sauce, so there’s very little preparation involved.

Costco sells its chicken Alfredo for $4.99 per pound. A typical tray costs around $18, depending on its weight.

If the price increases by 4% annually, the chicken Alfredo could cost approximately $7.39 per pound in 2036.

That means a tray costing $18 today could cost $26.64 in 10 years.

That’s an increase of $8.64 for the same amount of food.

I like Costco’s prepared meals because they’re convenient for busy weeknights. But if chicken Alfredo eventually costs nearly $27 per tray, I’d probably compare the price with making pasta Alfredo myself.

10. Sukhi’s Chicken Tikka Masala Could Cost Almost $24

Sukhi’s Chicken Tikka Masala is one of my family’s favorite easy meals from Costco.

My kids enjoy it, and I like keeping it in the refrigerator for nights when I don’t feel like cooking from scratch.

The regular price is $15.99.

If the price increases by 4% annually, the same package could cost $23.67 in 2036.

That’s an increase of $7.68.

At nearly $24, I’d probably pay closer attention to Costco’s sales before buying it.

11. Costco’s $5.99 Pumpkin Pie Could Cost Almost $9

Every Thanksgiving, Costco’s giant pumpkin pie is one of the seasonal bargains I look forward to buying.

For $5.99, you get an extra large pie. It’s hard to justify making one from scratch at that price.

But if the price increased by 4% annually, the same pumpkin pie could cost $8.87 by 2036.

That’s almost $3 more than today’s price.

And if you’re buying several pies for Thanksgiving, the difference becomes even more noticeable.

12. A Three Pack of Boursin Could Cost More Than $17

Costco is one of my favorite places to shop for cheese, especially when I’m putting together a charcuterie board for the holidays.

A three pack of Boursin costs $11.69 at my Costco.

If the price increases by 4% annually, that same package could cost $17.30 in 2036.

That’s an increase of $5.61.

While buying cheese in bulk can still be a good deal, I’d definitely compare prices before spending more than $17 on one package.

13. Costco SPAM Could Cost More Than $38

SPAM is another Costco pantry item that illustrates how much grocery prices could change over time.

A package priced at $25.89 today could cost $38.32 in 2036 if prices increase by 4% annually.

That’s an increase of $12.43.

14. Costco Bumble Bee Tuna Could Cost $25

Canned tuna is a convenient pantry staple to keep on hand for quick lunches.

At Costco, an eight pack of Bumble Bee solid white albacore tuna, with seven ounces per can, costs $16.89.

That works out to approximately $2.11 per can.

If the package price rises by 4% annually, the eight-pack could cost $25 in 2036.

That would be an increase of $8.11 for the same amount of tuna.

15. Fairlife Protein Shakes Could Cost Almost $60 Per Case

Protein shakes are a popular Costco purchase, especially for shoppers looking for convenient ways to add protein to their diets.

Costco sells Fairlife Nutrition Plan protein shakes in an 18 pack for $39.99 at regular price.

Each 11.5 ounce bottle contains 30 grams of protein, and Costco carries both chocolate and vanilla varieties.

If the regular price increases by 4% annually, that same 18 pack could cost approximately $59.19 in 2036.

That’s an increase of $19.20 per case.

At today’s price, each bottle costs approximately $2.22. Under the 2036 projection, that would increase to approximately $3.29 per bottle.

For someone who regularly drinks protein shakes, that difference can add up quickly.

If you buy two cases every month, you’d spend approximately $461 more annually at the projected 2036 price.

16. A Case of Costco Seltzer Could Cost More Than $13

If you shop at Costco regularly, you know how quickly beverages add up.

I buy Vintage seltzer by the case because my family drinks it regularly. It’s one of those things I almost always have in my Costco shopping cart.

A 15 pack priced at $8.99 today could cost $13.31 by 2036.

That might not sound like a huge increase, but if you purchase one case per week, that’s an additional $224.64 a year.

It’s a good example of how inflation on frequently purchased products can affect your grocery budget.

Costco Food Court & Rotisserie Chicken Prices Could Change, Too

17. Costco’s $4.99 Rotisserie Chicken Could Cost $7.39

Costco’s rotisserie chicken is one of the warehouse’s most famous bargains.

At $4.99, it’s difficult to find a better deal on a whole cooked chicken.

If that price increased by 4% annually, however, the chicken would cost approximately $7.39 in 2036.

That’s an increase of $2.40 per chicken.

For someone who buys one rotisserie chicken every week, that’s about $125 more per year at the projected price.

Of course, Costco has deliberately kept its rotisserie chicken priced at $4.99 for years, so there’s no guarantee it will follow inflation.

Still, it’s interesting to see what it would cost if Costco stopped holding the price steady.

18. The Famous $1.50 Costco Hot Dog Could Cost $2.22

Could you imagine paying more than $2 for Costco’s famous hot dog and soda combo?

Costco has maintained the $1.50 price since 1985, making it one of the most recognizable deals in the food industry.

Even as food costs have increased, the company has continued to protect that price.

But if the combo increased by 4% annually, it would cost $2.22 by 2036.

That’s still relatively inexpensive for a hot dog and drink, but it would be a noticeable change for Costco shoppers accustomed to paying $1.50.

Personally, I wouldn’t be surprised if Costco kept the $1.50 price for another decade.

19. A Whole Costco Pizza Could Cost Almost $15

One of the best bargains at Costco’s food court is its large 18 inch pizza.

At $9.95 for a whole pizza, it’s an affordable way to feed a family without spending a fortune on takeout.

If that price increased by 4% every year, the same pizza could cost $14.73 in 2036.

That’s nearly $5 more per pizza.

A single slice of Costco pizza, currently $1.99, would increase to approximately $2.95.

While those prices are still relatively affordable compared to many pizza restaurants, the increases illustrate how much even modest annual inflation can add up over time.

Costco Membership Fees Could Approach $200

20. Costco Executive Membership Could Cost $192 a Year

Costco membership fees have increased over the years.

In September 2024, Costco increased its Gold Star membership from $60 to $65 annually. Executive membership increased from $120 to $130 annually.

Those are the membership prices in 2026.

If Costco raised membership fees by 4% annually for 10 years, here’s what they could look like:

Membership	2026 Fee	Projected 2036 Fee
Gold Star	$65	$96.22
Executive	$130	$192.43

That means an Executive membership could cost almost $200 annually.

However, Costco doesn’t increase its membership fees every year. Historically, the company has raised its fees periodically rather than applying an annual inflation adjustment.

For Executive members, there’s also the annual 2% reward on qualifying purchases to consider.

I have an Executive membership, and I always look at how much I’m earning in rewards to decide whether the upgrade is worthwhile.

If membership eventually reached almost $200, I’d definitely want to make sure I was getting enough value to justify the fee.

A $300 Costco Shopping Trip Could Cost $444 in 2036

This is the comparison that surprised me the most.

If you regularly spend $300 on a Costco shopping trip, that same basket of groceries and household items could cost $444.07 in 2036 if prices rise by 4% annually.

That’s an additional $144.07 for the same purchases.

And if you shop at Costco twice a month, the difference becomes significant.

Shopping Frequency	2026 Annual Cost	Projected 2036 Annual Cost
Once a month	$3,600	$5,328.84
Twice a month	$7,200	$10,657.68
Three times a month	$10,800	$15,986.52
Four times a month	$14,400	$21,315.36

For someone making two $300 Costco trips per month, that works out to approximately $3,458 more annually.

And that’s without buying anything extra.

Of course, most shoppers would adjust their spending habits if prices increased significantly. They might purchase fewer prepared meals, switch brands, or shop sales more carefully.

Still, these numbers show how even relatively modest annual price increases can compound over time.

What If Costco Prices Increase by 3% or 5% Instead?

There’s no way to know exactly how much Costco prices will increase over the next decade.

Inflation doesn’t move at a consistent rate every year, and individual products can go up or down in price depending on production costs, supply chains, competition, and other factors.

To see how different inflation assumptions affect the final price, I compared three scenarios.

Costco Item	3% Annual Increase	4% Annual Increase	5% Annual Increase
Rotisserie chicken	$6.71	$7.39	$8.13
Hot dog combo	$2.02	$2.22	$2.44
Whole pizza	$13.37	$14.73	$16.21
Organic eggs, 2 dozen	$11.14	$12.27	$13.50
Ultra-filtered milk, 3 pack	$16.92	$18.64	$20.51
Chobani yogurt	$24.18	$26.63	$29.30
Chicken Alfredo tray	$24.19	$26.64	$29.32
Chicken pot pie	$32.24	$35.51	$39.08
Fairlife protein shakes, 18-pack	$53.74	$59.19	$65.14
Executive membership	$174.71	$192.43	$211.76
$300 shopping trip	$403.17	$444.07	$488.67

These are mathematical illustrations, not forecasts.

Even at the lower 3% annual rate, a $300 Costco shopping trip would exceed $400 after 10 years.

At 5%, that same basket would cost nearly $489.

Will Costco Actually Raise Its Prices This Much?

Not necessarily.

One reason I like shopping at Costco is that the company has historically focused on offering competitive prices to its members.

Its famous $1.50 hot dog and $4.99 rotisserie chicken are good examples of products that haven’t followed typical inflation patterns.

But not every Costco product has a protected price.

Prepared meals, packaged groceries, beverages, meat, dairy, and other merchandise can change in price depending on costs and market conditions.

Costco has also raised membership fees periodically, so there’s no guarantee today’s membership costs will remain the same in 2036.

Another thing to remember is that the inflation scenarios assume products remain identical.

In reality, package sizes, ingredients, and product availability could change over the next decade.

How I’m Trying to Keep My Costco Shopping Bill Down

Even though I like shopping at Costco, I don’t assume everything is automatically a bargain.

Over the years, I’ve learned that buying in bulk only saves money if my family actually uses what I buy.

Here are some of the things I do to keep my Costco shopping bill under control:

I watch for Costco clearance prices ending in .97.
I compare unit prices instead of assuming the larger package is cheaper.
I avoid buying oversized packages of perishable foods that my family won’t finish.
I pay attention to regular prices so I can recognize a genuinely good sale.
I try to limit impulse purchases, especially clothing and seasonal merchandise.
I buy Costco prepared meals selectively, based on how many servings we’ll actually get.

I also keep track of my Costco purchases and share many of my shopping finds and prices on my Suburbs 101 Youtube channel.

What Costco Prices Could Look Like in 2036

Here’s what some popular Costco groceries and food court favorites could cost in 10 years if their prices increased by 4% annually.

Costco Product	2026 Price	Projected 2036 Price
Rotisserie chicken	$4.99	$7.39
Hot dog and soda combo	$1.50	$2.22
Whole food court pizza	$9.95	$14.73
Pizza slice	$1.99	$2.95
Chicken bake	$3.99	$5.91
Kirkland Ultra-Filtered 2% Milk, 3 × 64 oz	$12.59	$18.64
Organic eggs, 2 dozen	$8.29	$12.27
Bananas	$1.99	$2.95
Broccoli florets, bag	$7.99	$11.83
Boursin cheese, 3-pack	$11.69	$17.30
SPAM	$25.89	$38.32
Bumble Bee albacore tuna, 8 × 7 oz	$16.89	$25.00
Sukhi’s Chicken Tikka Masala	$15.99	$23.67
Kirkland Ancient Grains Granola	$8.89	$13.16
Chobani yogurt	$17.99	$26.63
Chicken street taco kit	$16.99	$25.15
Chicken pot pie	$23.99	$35.51
Kirkland Chicken Alfredo, tray	$18.00	$26.64
Pumpkin pie	$5.99	$8.87
Vintage seltzer 15-pack	$8.99	$13.31
Fairlife Nutrition Plan, 18-pack	$39.99	$59.19
Gold Star membership	$65.00	$96.22
Executive membership	$130.00	$192.43

These prices are based on my Costco shopping finds and published membership and food court prices. Grocery prices vary by warehouse and package size. The 2036 prices are mathematical projections, not predicted Costco prices.

It’s impossible to predict exactly how much Costco groceries will cost in 2036.

But if prices increase by an average of 4% annually, today’s $300 Costco shopping trip could cost $444 in just 10 years.

Even an Executive membership could approach $200 annually.

Of course, Costco could continue keeping some of its most popular items at the same prices for years to come.

Personally, I’m hoping the $1.50 hot dog and $4.99 rotisserie chicken are still around in 2036.

Methodology: The projections use 2026 prices multiplied by 1.04 to the tenth power, assuming a constant 4% annual increase. Additional scenarios use 3% and 5% annual increases. The starting prices include Costco membership and food court prices and prices observed during my Costco shopping trips. Grocery prices and availability vary by location. The 2036 figures are hypothetical illustrations, not forecasts or announced future Costco prices. Sales tax is excluded.
