What it does not do
- It adds, multiplies and compares Sonic's numbers. It does not estimate anything.
- It leaves out items that are not in the Fall 2026 guide, and drink add-ins and burger add-ons.
- It does not compare prices, because Sonic publishes none.
- It does not call any item healthier. “Higher” only marks the larger number.
Sonic publishes no menu prices. Prices on Sonic Menu are not Sonic's: where we could, we show a typical pickup price measured by Drive Thru Index across a sample of Sonic restaurant pages (checked November 6, 2026); for a few items we could not measure, a rough estimate of our own. They are not live prices from any single restaurant. Exact menu prices, combo meal promotions, and product availability vary by independent franchise location, drive-in stall vs. drive-thru, and delivery service app markups (DoorDash, Uber Eats, Grubhub).
