Because each Dairy Queen franchise is individually owned and operated, there is no standard time period in which menu prices change at all locations. Each individual Dairy Queen franchise determines its own prices and can change them at any time.
While Dairy Queen's corporate headquarters provides suggestions for retail prices, these suggestions are not mandatory. In general, fast food and restaurant businesses raise prices due to both internal and external factors such as food cost, profit margins, labor costs, market volatility and competition. Financial experts in the food industry recommend that owners review menu prices at least twice every year to account for changes in any of these areas.
