Fast-food value menus have become surprisingly complicated. McDonald’s has meal deals starting at $5 and an Under $3 Menu, Wendy’s now offers $4, $6, and $8 Biggie Deals, and Burger King mixes limited-time bundles with Royal Perks offers that can change what you get for your money. That makes comparing a $5 or $6 lunch much more useful than simply asking which chain has the cheapest burger. For this comparison, we’re looking at the food included in the chains’ current advertised value offers, while keeping in mind that prices and participation can vary by restaurant. Once you put the meals side by side, one thing becomes clear: McDonald’s and Wendy’s currently provide the easiest path to a complete low-cost meal, while Burger King can become especially interesting if you’re willing to build your own combination.
