Wendy’s vs Sonic: Prices, Burgers, Drinks & Who Wins 2026
By Jimmy
Wendy’s wins on burgers, price and value. Sonic wins on drinks and the drive-in experience. Late night depends on your location. The numbers explain why: a Jr. Bacon Cheeseburger is $3.29 and 350 calories at Wendy’s, against a $1.99 limited-time deal price and 400 calories at Sonic, while Sonic’s slushes, limeades and Happy Hour have no answer at Wendy’s.
This is a practical head-to-head, not a taste test from memory. The Wendy’s prices and calories below come from our own Wendy’s menu, drinks, Frosty and breakfast tables, so every Wendy’s figure is one we publish ourselves. Sonic calories come from Sonic’s own menu at sonicdrivein.com. Sonic publishes no national price list, so Sonic prices are shown as TBC except the items Sonic itself prices on its menu and deals pages, and they vary by location. Where a figure could not be checked, it is marked TBC rather than guessed.
The verdict, category by category
| Category | Winner | Why |
|---|---|---|
| Burgers | Wendy’s | A $3.29 Jr. Bacon Cheeseburger at 350 calories and a $6.30 Dave’s Single beat Sonic’s heavier burgers. |
| Chicken | Wendy’s | Spicy Chicken is $6.49 and 560 calories; Sonic’s only chicken sandwich is its 520-calorie Crispy Chicken, with no price published. |
| Tots and fries | Sonic | Tater Tots are the signature side, and Onion Rings and Groovy Fries give Sonic a wider side menu. |
| Drinks | Sonic | Slushes, limeades, Ocean Water and shakes, plus half-price Happy Hour, beat Wendy’s smaller drink menu. |
| Dessert | Tie | A Classic Frosty is $1.79 to $3.79; Sonic’s shakes and slushes are bigger and heavier, so it depends on what you want. |
| Breakfast | Wendy’s | A $4.99 Breakfast Baconator and breakfast until 10:30 a.m. beat Sonic’s burritos, whose prices are TBC. |
| Price | Wendy’s | Biggie Deals at $4, $6 and $8 and a $5 Biggie Bag give Wendy’s the clearer cheap meal. |
| Value and deals | Tie | Sonic’s $1.99 Jr. Bacon Cheeseburger is the cheapest burger in this comparison, but it is a limited-time deal, while Wendy’s $5 Biggie Bag is a full meal every day. |
| App and rewards | Tie | Wendy’s Rewards earns 10 points per $1; SONIC Rewards gives a free burger on joining and points per $1 spent. |
| Experience and late night | Sonic | The drive-in with carhops is the more fun visit, and many locations stay open late; check your location. |
No single winner takes every category, which is the point. Wendy’s is the better everyday stop for food and value, and Sonic is the better stop for drinks and the experience. The duels below show the exact prices and calories behind each verdict.
Burgers: Jr. Bacon Cheeseburger vs Sonic’s burgers
Wendy’s burgers are built on fresh, never-frozen beef. The Jr. Bacon Cheeseburger is the value pick of the whole comparison: $3.29 and 350 calories. Sonic’s burgers run heavier. Its SONIC Cheeseburger is 700 calories, its SuperSONIC Double Cheeseburger is 1,040 calories and its SuperSONIC Bacon Double Cheeseburger is 1,060 calories, and Sonic publishes no national price for any of them. The one exception is the Jr. Bacon Cheeseburger itself, which Sonic currently sells for $1.99 on its limited-time $1.99 Menu at participating locations.
| Burger | Wendy’s price and calories | Sonic price and calories |
|---|---|---|
| Jr. Bacon Cheeseburger | $3.29, 350 cal | $1.99 (limited-time $1.99 Menu), 400 cal |
| Dave’s Single vs SONIC Cheeseburger | $6.30, 560 cal | TBC, 700 cal |
| Double Stack vs SuperSONIC Double Cheeseburger | In the $6 Biggie Bag; standalone price and calories TBC | TBC, 1,040 cal |
| Baconator vs SuperSONIC Bacon Double Cheeseburger | $8.79, 890 cal | TBC, 1,060 cal |
On nutrition, the Jr. Bacon Cheeseburger duel is the one comparison with a full head-to-head behind it. Tasting Table compared the two burgers in October 2026 and found Wendy’s at 350 calories, 21 grams of fat and 650 milligrams of sodium, against Sonic at 400 calories, 26 grams of fat and 1,440 milligrams of sodium. Sonic’s burger has no trans fat, against 0.5 grams at Wendy’s, and both have 8 grams of saturated fat. Wendy’s wins the numbers, and by a wide margin on sodium, but Sonic wins the price while its $1.99 deal lasts.
For a bigger burger, the choice flips on size. Dave’s Double is $7.50 and 810 calories, which is a lot of burger for the money, while Sonic’s SuperSONIC Double is 1,040 calories before any price is added. If you want the biggest burger in this comparison, Sonic has it. If you want the best burger for the price, Wendy’s has it. Our other burger comparisons, Wendy’s vs McDonald’s and Wendy’s vs Burger King, use the same tables.
Chicken: Spicy Chicken vs Sonic’s Crispy Chicken
Wendy’s Spicy Chicken Sandwich is $6.49 and 560 calories, and it is the strongest chicken sandwich in this comparison on flavour and on value. Sonic’s answer is its Crispy Chicken Sandwich at 520 calories, with no national price published. Sonic’s current national menu lists only that one chicken sandwich, alongside Chicken Tenders and Premium Chicken Bites, so there is no separate Classic or Spicy chicken sandwich to compare at Sonic. Wendy’s has the wider chicken menu, with the Spicy Chicken Sandwich leading it, and Sonic’s chicken is a side note to its burgers and drinks.
| Chicken | Wendy’s price and calories | Sonic price and calories |
|---|---|---|
| Spicy Chicken Sandwich vs Crispy Chicken Sandwich | $6.49, 560 cal | TBC, 520 cal |
| Chicken Nuggets vs Chicken Tenders (3 pc) | In Biggie Deals; standalone price and calories TBC | TBC, 260 cal |
| Chicken Nuggets vs Chicken Tenders (5 pc) | In Biggie Deals; standalone price and calories TBC | TBC, 430 cal |
On calories alone, Sonic’s Crispy Chicken Sandwich is the lighter sandwich at 520 calories against 560, and its 3-piece tenders are only 260 calories. But a sandwich you cannot price is hard to recommend on value, and Wendy’s Spicy Chicken is $6.49 with the calories to match. Chicken goes to Wendy’s, and it is not close on choice.
Tots and fries: Natural-Cut Fries vs Tater Tots
This is the duel Sonic was built for. Tater Tots are Sonic’s signature side, and they come with Onion Rings at 580 calories and Groovy Fries at 290 calories as alternatives. Wendy’s Natural-Cut Fries are the simpler, cheaper side, from $1.79 for a small at 210 calories to $3.39 for a large at 470 calories. Sonic does not publish a national price for Tots, so the price comparison ends there, but the calories tell the story: Tots run from 250 to 360 calories by size, which puts them in the same range as a regular order of Wendy’s fries.
| Side | Wendy’s price and calories | Sonic price and calories |
|---|---|---|
| Natural-Cut Fries (small) vs Tater Tots | $1.79, 210 cal | TBC, 250 to 360 cal by size |
| Natural-Cut Fries (large) vs Onion Rings | $3.39, 470 cal | TBC, 580 cal |
| Natural-Cut Fries (regular) vs Groovy Fries | $1.79 to $3.39, 210 to 470 cal | TBC, 290 cal |
Tots win on character and on choice, because Sonic’s side menu is wider and more fun. Fries win on price, because you can get a small order at Wendy’s for $1.79 and you always know what it costs. If the side is the reason you are going, go to Sonic. If the side is an extra with a burger, Wendy’s fries are the better buy.
Drinks: Frosty and soft drinks vs slushes, limeades and shakes
Drinks are where Sonic pulls away, and it is the biggest gap in this comparison. Sonic’s drink menu runs to slushes, limeades, lemonades, Ocean Water, shakes, floats and soft drinks, with flavours you cannot get anywhere else. Wendy’s drink menu is much smaller: soft drinks, lemonades, coffee and the Frosty. A Classic Frosty is $1.79 to $3.79 and 190 to 510 calories, and it is still the best dessert-drink in fast food, but it is one item against a whole menu. Our full Wendy’s drinks menu and Frosty menu show the whole Wendy’s side of this duel.
| Drink | Wendy’s price and calories | Sonic price and calories |
|---|---|---|
| Coca-Cola vs Coca-Cola | $2.29 to $3.29, 180 to 320 cal | TBC, 180 cal |
| All-Natural Lemonade vs All Natural Lemonade | $2.89 to $3.79, 190 to 330 cal | TBC, 270 cal |
| Strawberry Lemonade vs Cherry Limeade | $2.89 to $3.79, 230 to 430 cal | TBC, 240 cal |
| Classic Frosty vs Cherry Slush | $1.79 to $3.79, 190 to 510 cal | TBC, 270 cal |
| Classic Frosty vs Classic Chocolate Shake | $1.79 to $3.79, 190 to 510 cal | TBC, 720 cal |
Sonic’s Happy Hour is the other half of the drinks story. Every day from 2 to 4 p.m., Sonic offers half-price drinks and slushes at participating locations, including soft drinks, iced teas, lemonades, limeades, Ocean Water and slushes. It is the best drinks deal in fast food, and it is the single best reason to time a Sonic visit for the afternoon. Two things to know: Happy Hour is not listed on Sonic’s current Deals page, so times and participation can vary by location, and you should check the Sonic app before you go. Wendy’s answer is a 99-cent any-size soft drink with a qualifying purchase in the app, which is a good deal, but it is not half-price slushes.
Ocean Water deserves a line of its own. It is Sonic’s blue coconut-lime drink at 200 calories, and Wendy’s has nothing like it. The same is true of Cherry Limeade at 240 calories, or 15 calories as a diet version. If drinks decide where you eat, Sonic wins this category by a wide margin, and the Frosty is the only Wendy’s drink that keeps it close.
Breakfast: Breakfast Baconator vs burritos and French Toast Sticks
Wendy’s serves breakfast from 6:30 to 10:30 a.m., and it is the more complete breakfast of the two. The Breakfast Baconator is $4.99 and 630 calories, and it is the headline item on a menu that also has French Toast Sticks, croissants and burritos. Sonic’s breakfast is built around burritos and toasters, with the Ultimate Meat and Cheese Burrito at 820 calories as the biggest item, and French Toast Sticks at 570 calories. Sonic does not publish national breakfast prices or breakfast hours, so those are TBC and vary by location.
| Breakfast | Wendy’s price and calories | Sonic price and calories |
|---|---|---|
| Breakfast Baconator vs Ultimate Meat and Cheese Burrito | $4.99, 630 cal | TBC, 820 cal |
| French Toast Sticks (4 pc) vs French Toast Sticks | $3.19, 460 cal | TBC, 570 cal |
| Bacon, Egg and Swiss Croissant vs Bacon Breakfast Toaster | $4.49, 420 cal | TBC, 470 cal |
| Breakfast Burrito (Bacon) vs Bacon Breakfast Burrito | $4.99, 700 cal | TBC, 470 cal |
Wendy’s wins breakfast on price, on hours you can plan around and on choice at the lower end, with a Sausage Biscuit at $2.19 and 470 calories and coffee from $1.59. Sonic wins on the heartiest single item, because an 820-calorie burrito is a full meal in itself, and on the toaster sandwiches, which Wendy’s does not match. For a full breakfast, see our Wendy’s breakfast menu. For most mornings, Wendy’s is the easier choice, and it is the cheaper one where prices are known.
Value and deals: Biggie Deals vs Happy Hour and the $1.99 Menu
Value is where the two chains play different games. Wendy’s Biggie Deals are the clearest value menu in fast food: Biggie Bites at $4, a Biggie Bag at $6 and a Biggie Bundle at $8, with a $5 Biggie Bag also on the national ordering menu. A Dave’s Single combo is $7.99. Sonic’s value is built on deals rather than a fixed value menu: a $7 Big Deal Meal at 940 calories, a $9 Big Deal Meal at 1,050 calories, and the $1.99 Menu, where the Jr. Bacon Cheeseburger, Crispy Tender Wraps and small floats are $1.99 for a limited time at participating locations.
| Value | Wendy’s | Sonic |
|---|---|---|
| Cheapest burger | Jr. Bacon Cheeseburger, $3.29 | Jr. Bacon Cheeseburger, $1.99 (limited-time $1.99 Menu) |
| Cheapest full meal | $5 Biggie Bag | $7 Big Deal Meal, 940 cal |
| Value tiers | Biggie Deals, $4, $6 and $8 | $7 and $9 Big Deal Meals |
| Burger combo | Dave’s Single combo, $7.99 | $9 Big Deal Meal, 1,050 cal |
| Drink deal | 99-cent any-size soft drink with a qualifying purchase (app) | Happy Hour, 2 to 4 p.m., half-price drinks and slushes |
Sonic has the cheapest burger in this comparison, at $1.99 against $3.29, but only while the deal lasts and only at participating locations. Wendy’s has the cheapest full meal, and the most predictable one, because a Biggie Bag is $5 or $6 every day, not a limited-time offer. Our Wendy’s deals page has the current Biggie Deals and app offers. On meals, Wendy’s wins. On a single burger or a single drink, Sonic wins while its deals run.
App and experience: Wendy’s Rewards vs SONIC Rewards, drive-thru vs drive-in
The experience is the real difference between these two chains, and it is not about the food. Wendy’s is a drive-thru and dine-in chain with delivery through the app, and Wendy’s Rewards earns 10 points per $1, with rewards starting at 200 points (check the app for current thresholds). Sonic is a drive-in: you park in a stall, order from your car, and a carhop brings the food out to you. You can also order ahead in the Sonic app for pickup, and Sonic delivers through the app. SONIC Rewards gives you a free burger when you join, earns points for every $1 you spend in the app or online, and has Star and Legend status levels, with welcome and birthday offers.
| Experience | Wendy’s | Sonic |
|---|---|---|
| Ordering | Drive-thru, dine-in and app | Drive-in stalls with carhops, app pickup and delivery |
| Rewards | Wendy’s Rewards, 10 points per $1 | SONIC Rewards, free burger on joining, points per $1 spent |
| Breakfast hours | 6:30 to 10:30 a.m. | Vary by location, TBC |
| Late night | Varies by location | Varies by location; some drive-ins are open 24 hours |
| Kids | Kids Meal, $4.60 to $6.29 | Wacky Pack Kids Meals, price TBC |
For kids, Wendy’s has the clearer deal, with a Kids Meal from $4.60 to $6.29, while Sonic’s Wacky Pack is the more fun meal and its price is set by location. For late night, both chains vary by location, and you should check the hours of your local restaurant before you go; Sonic’s drive-in format and the locations that stay open late, some of them 24 hours, give it the edge for a late-night stop. Wendy’s delivery is available through the app, and our Wendy’s delivery page has the details.
Conclusion
Wendy’s vs Sonic is not a close call overall, but it is a close call in the right places. Wendy’s is the better everyday restaurant: better burgers, a clearer value menu, a better chicken sandwich and a breakfast you can plan around. Sonic is the better experience: the best drinks menu in fast food, Tater Tots, a drive-in with carhops and a Happy Hour that no other chain matches. Most days, eat at Wendy’s. When you want a drink, a snack and somewhere fun to sit in your car, go to Sonic, and go between 2 and 4 p.m.
- Cheapest: Sonic, with the $1.99 Jr. Bacon Cheeseburger, while the deal lasts; Wendy’s for a full meal, with the $5 Biggie Bag.
