If you thought that all McDonald’s restaurants in Phoenix, Arizona had the same price then you were wrong. In a table originally shared to Reddit, there is actually quite a cost discrepancy depending on each location.

Buying 4 set products from the menu costs as low as $20.05 in Cave Creek, which costs as high as $29.36 on 67th Ave. Which is over a 45% increase in price when comparing the two directly. This may not seem like a lot, although if you eat fast food regularly then the costs (or savings) will of course add up.

A double quarter pounder in particular has the most variation, with a low of $6.29 and a high of $9.69 – both of which are a lot higher than Times Square in NYC.

However, there are several key reasons why prices will be different from one McDonald’s location to another, here are the 6 main ones.

1. Operating Costs: The cost of operating a McDonald’s restaurant can vary significantly depending on the city or location. Expenses like rent, utilities, labor, and food sourcing can be higher in some areas, leading to higher menu prices to cover these costs.
2. Local Regulations: Local regulations and taxes can impact menu prices. Some cities or regions may have higher taxes on restaurant food or specific regulations that affect pricing. These costs may be passed on to customers in the form of higher prices.
3. Competitive Landscape: The level of competition in a particular area can influence menu prices. In highly competitive markets, McDonald’s may adjust its prices to remain competitive with other fast-food chains or local restaurants.
4. Economic Factors: The economic conditions in a city can also play a role. In areas with higher living costs or stronger economies, consumers may be willing to pay more for fast food, allowing McDonald’s to charge higher prices.
5. Franchise Ownership: Many McDonald’s restaurants are independently owned and operated by franchisees. Franchisees have some flexibility in setting menu prices, within certain guidelines set by the corporation. This can result in price variations between different franchise locations.
6. Local Demographics: The demographic makeup of a city or neighborhood can influence pricing decisions. McDonald’s may adjust its prices to cater to the purchasing power and preferences of the local population.
