The price is so, so wrong.

Recently, a ridiculously wimpy $29 ham and cheese sandwich from Eli Zabar’s E.A.T. on the Upper East Side went viral for its absurd price tag, which made the $5 pizza slices at Fini in Williamsburg, Brooklyn, seem like a relative bargain.

It’s just the latest insult to New Yorkers’ wallets, which have been hit by skyrocketing pricing everywhere from the movie theater to the local barbershop. A can of craft beer is nearing $10, a shoe shine will run you $15 and a dry cleaning trip will end up taking you to the cleaners.

Sure, NYC has never been a cheap place to live, but for the first time ever, it topped the list of most expensive cities in the world, according to the annual Economist Intelligence Unit survey released in December.

Nationwide, the inflation rate has slowed to 5% — the lowest level in nearly two years — but you wouldn’t know it here in NYC, where businesses are slapping on premiums that in some cases more than double the cost of similar goods and services offered elsewhere.

And you don’t have to travel far to find far lower prices — just to the surrounding suburbs.

It’s a major reason why city dwellers cross county lines to do their shopping, according to Anoop Rai, finance professor at the Frank G. Zarb School of Business at Hofstra University on Long Island.

So, are Big Apple businesses slapping on steep markups for legitimate reasons — or because they can?

According to Rai, the answer is a bit of both.

The city commands “higher wages relative to the suburbs, primarily because taxes are higher in the city,” Rai told The Post.

Then there is the cost of getting goods into the city, which “is more difficult, and you have to pay extra,” he said. (The city’s proposed congestion pricing scheme would further inflate those numbers.)

While wages, taxes and burdensome regulations all contribute to the NYC premium, there are other, more capricious factors at play.

Limited transportation options — “most people are walking or taking a bus,” said Rai — mean business owners know they have something of a captive audience who will pay for convenience.

“The same goods that are in the suburbs are more inelastic in the city,” he explained.

And there’s no limit to what you can charge in Gotham, which “has some of the richest people in the world,” Rai said. That’s no exaggeration: according to a new Henley & Partners survey, NYC is the richest city in the world, with roughly 340,000 millionaires.

“If you brand and market it appropriately, you can get away with that kind of pricing. As a result, I’m not shocked to hear there’s a sandwich for $29.”

Here are some examples of the New York premium — compared to the substantially cheaper alternatives that await outside the five boroughs.

You’ll be lovin’ it cheaper. McDonald’s prices are about a dollar less in Westchester than they are in Midtown. A Big Mac on the Hudson will run you $6.39 compared to $7.69 in Times Square. Several other items in the Manhattan store run about a dollar more than in Tarrytown, NY — including a quarter pounder with cheese extra-value meal ($13.69 vs. $12.12).

You’ll also see the price differential at other beloved chains. At Domino’s, a large, hand-tossed Meatzza pie is $19 in Parsippany, NJ, compared to $23 at its 72nd and Broadway location.

A steak burrito from Chipotle costs $12.45 on Eighth Avenue in Midtown, compared to $10.95 in White Plains, Westchester.

A 16 ounce can of Tools of the Trade American Pale Ale is $9 at Carmine Street Beers, whereas a four-pack of the same brew at the same size is $16 — so $4 a piece — on Long Island at Bellmore’s All Island Beverage.

Buy enough, and you can legally down a few cans on the LIRR back and still save money.

Head up to the ritzy suburb of Greenwich, Connecticut, to get your shoes spiffed at about half the cost of city prices. Greenwich Shoe Repair will do a shine for $8 as opposed to the $15 service from Cobbler Express on 42nd Street near Grand Central Station.

If you’re pressed for cash, head out to LI to get your shirts done right. Spin Sudz of Stony Brook dry cleans men’s and women’s shirts for $3.25 apiece. The Manhattan- and Brooklyn-based Morris Cleaners dry cleans shirts for $7 — more than double the cost.

Leave the NYC nest and fly up to Westchester for an exceptional and cheap bacon, egg and cheese. The iconic 24-hour deli Rocky’s in Millwood, NY, sells the staple sandwich for $4.55 — compared to a $7.99 offering at Al’s Deli near Penn Station.

You’ll look forward to trimming this cost. Nucky’s Grooming Gallery of Massapequa, NY, does a hot towel shave for $23 — less than half of the $55 “express” shave at Pall Mall Barbers on the Rockefeller Center Concourse.

A trip to the Constitution State to catch a movie will save you a bill as well. Tickets at South Norwalk’s AMC theater run at $14.49 for adults. The same chain’s 84th street location sells seats for $25.49.

A nice steak is rarely cheap, but it will really cost you in the city. Capital Grille on Wall Street sells a 14-ounce dry-aged strip steak for $63. That same steak is only $53 at the Stamford, Conn., location.

The difference in gym prices will make you sweat. Plans for Blink fitness’ Murray Hill location begin at $39. On Long Island in Melville, they begin at $15.

Suffolk County’s La Roma pastry shop in Bohemia sells pastries such as cannolis, eclairs and Nutella tarts at $3.50 apiece. Over at Ferrara’s in Little Italy, expect to pay around double (including $6.75 for an entry-level cannoli).

There’s a lot of truth to the old adage “Make sure you get gas in New Jersey.” Regular gas this week is going for $3.59 at a BP in Caldwell, NJ, according to Autoblog.com.

In Manhattan, the site notes, a Mobil on 96th Street near the Henry Hudson Parkway is $4.89.
