MenuPriceTracker vs. Delivery Apps & Other Price Sites

How do these prices compare to what Uber Eats, DoorDash, or Grubhub show?

Uber Eats, DoorDash, Grubhub, and Seamless inflate McDonald's menu prices by 15–30% on top of the in-store price before adding delivery fees, service fees, and tip. The price you see on a delivery app is not what McDonald's charges at the counter. MenuPriceTracker shows the real menu price from the McDonald's app — what you'd actually pay walking into the restaurant or ordering at the kiosk.

Why not just check TripAdvisor for McDonald's prices?

TripAdvisor doesn't track individual McDonald's store prices. Any price information on TripAdvisor is user-submitted, covers only a small fraction of locations, and can be months or years out of date. MenuPriceTracker tracks store-level prices for 9,200+ US McDonald's locations across all 50 states, refreshed monthly from the McDonald's app.

Where does MenuPriceTracker get McDonald's price data?

Prices are collected at the store level from the McDonald's app, covering 9,200+ locations in every US state. Each store's data is refreshed monthly so you see real local prices — not a national estimate, a delivery markup, or crowdsourced guesses. The national average, state averages, and per-city averages on this site are all computed from that same store-level data.
