How to read the prices. Each figure is the median price across about 424 restaurant listings sampled in 38 states (weighted by how many Sonic restaurants each state has), read from Drive Thru Index. The range is the lowest and highest price in that sample. Your drive-in sets its own price.
Sonic does not publish a ring count or a weight for these sizes, so we show no per-ring or per-ounce figures. "Cents per 100 calories" only compares sizes on price; it is not a recommendation to eat more.

Sodium and sugar in context (Medium)
570 mg
sodium (25% of 2,300 mg)
19 g
total sugars
4.8
teaspoons of sugar (4 g each)
The American Heart Association recommends no more than 2,300 mg of sodium a day, with an ideal goal of 1,500 mg for most adults, and no more than 36 g (men) or 25 g (women) of added sugar. Sonic lists total sugars, not added sugars, and onions contain some natural sugar, so the sugar bars are a comparison and not an exact added-sugar count. Sauces add more of both.
What the numbers say
- Carbohydrate is the biggest part: 74 g, of which 19 g is sugar and 4 g is fiber. Fat is 29 g (5 g saturated, 0 g trans) from the frying oil and coating, and protein is 8 g.
- Cholesterol is 0 mg. The rings contain buttermilk and whey in the coating, but Sonic lists no cholesterol for them.
- Sodium is 25% of the FDA daily value before any dipping sauce. Some sauces add a lot more, so check the dip calculator below.

How we measured prices
Drive Thru Index has no page for onion rings alone, so we read the onion ring prices from 425 Sonic restaurant listings across 38 states, up to 12 per state, picked by a fixed random seed. The US figure is the median, weighted by how many Sonic restaurants each state has. A state figure is the median of the restaurants sampled there, and a state is shown only if at least 3 sampled restaurants listed that size. Treat every figure as "about": prices differ by drive-in, change often and are higher on delivery apps.

What we could not verify
- How many rings, or how many ounces, come in each size: Sonic does not publish it, so there is no per-ring calorie figure here.
- Fresh or frozen: Sonic does not say whether the rings are made in-store or arrive frozen, or how the onion is cut.
- Frying oil for this item: not named in the ingredient statement we used.
- Added sugars, vitamins and minerals: Sonic's guide lists total sugars only.
- Sauce prices and how many cups come with an order: we found no reliable source, so we do not state them.
