Sonic Milkshakes Cost
Sonic Milkshakes Prices in 2025: How Much Does America’s Favorite Drive-In Shake Really Cost?
When it comes to thick, creamy, indulgent milkshakes, few chains can compete with Sonic Drive-In. Famous for its massive flavor menu (over 25 core flavors and more than 1 million drink combinations when you include add-ins), Sonic milkshakes have earned a cult following.
But with inflation still lingering and menu prices creeping upward, many fans want to know: how much does a Sonic milkshake actually cost in 2025?
In this complete pricing guide, we’ll break down current Sonic milkshake prices across sizes, popular flavors, limited-time offerings, Happy Hour deals, and regional variations—so you can satisfy your craving without sticker shock.
Sonic Milkshake Sizes and Base Prices (2025 Nationwide Average)
Sonic offers four classic sizes for its Hand-Mixed Master Shakes and Classic Shakes:
- Mini (10–12 oz) – $2.79 – $3.49
- Small (14 oz) – $3.79 – $4.59
- Medium (20 oz) – $4.99 – $5.79
- Large (32 oz) – $5.99 – $7.29
The most popular size by far is the Medium, which delivers the best value per ounce. A Large is essentially two Mediums for only about $1–$1.50 more, making it ideal for sharing (or not sharing).
Signature “Master Shakes” vs Classic Shakes Pricing
Sonic divides its milkshake lineup into two tiers:
- Classic Shakes (vanilla, chocolate, strawberry, fresh banana, peanut butter, hot fudge, caramel)
→ These use the base prices listed above. - Master Shakes & Master Blasts (more elaborate creations with mix-ins and toppings)
Examples: Oreo Cheesecake, Strawberry Cheesecake, Chocolate Chip Cookie Dough, Peanut Butter & Cookie Dough, Turtle Pecan, etc.
→ These cost an extra $0.60–$1.20 depending on location.
Typical Master Shake upcharge (2025):
- Mini +$0.60
- Small +$0.80
- Medium +$0.90
- Large +$1.00–$1.20
So a Medium Oreo Cheesecake Master Shake usually lands between $5.89 and $6.69 before tax.
Real Cream vs “Real Ice Cream” – Why Sonic Shakes Are Pricier Than Some Competitors
Sonic proudly advertises “Real Ice Cream” shakes made with 100% real ice cream (not soft-serve “frozen dairy dessert” like many fast-food rivals). This premium ingredient is the main reason a medium shake costs $1–$2 more than similar-sized shakes at McDonald’s or Burger King. Fans argue the thicker texture and richer taste are worth every penny.
Happy Hour & Half-Price Shake Deals (The Best Time to Buy)
The single biggest money-saver at Sonic remains Happy Hour, every day from 2–4 p.m.:
- All shakes and ice cream slushes – ½ price
- Example: Medium Master Shake normally $6.29 → only $3.15 during Happy Hour
Late-night fans also get the same 50% off deal after 8 p.m. at most locations. Download the Sonic app and you’ll occasionally see app-exclusive offers such as:
- $1.99 any size Classic Shake (limited time)
- Buy One Get One Free Master Shakes
- Free Medium Shake with any $10+ purchase
Limited-Time & Seasonal Shake Prices (2025)
Sonic rolls out 4–6 limited-time shake flavors every year. Recent and upcoming 2025 LTOs include:
- Churro Shake (cinnamon sugar + dulce de leche) – $5.69–$6.89 medium
- Espresso Shake (real espresso + vanilla ice cream) – $5.99–$7.19 medium
- Peanut Butter Bacon Shake (yes, it’s real) – $6.29–$7.49 medium
- Holiday Mint or Eggnog Shake (Nov–Dec) – $6.19–$7.39 medium
These specialty shakes are almost always priced at the higher end of the Master Shake range.
Regional Price Differences Across the United States
Prices can vary dramatically by state and even by city because most Sonic locations are franchised:
Lowest average prices (Medium Classic Shake):
- Oklahoma, Texas, Arkansas – $4.79–$5.29
- Midwest (Missouri, Kansas) – $4.99–$5.59
Highest average prices:
- California, New York City metro, Washington state – $6.29–$7.29
- Hawaii & Alaska – $7.49–$8.99 (yes, really)

Sonic Milkshake Calories & Nutrition (For the Curious)
Just so you know what you’re indulging in:
- Medium Classic Chocolate Shake – ~790 calories
- Medium Oreo Cheesecake Master Shake – ~1,080 calories
- Medium Strawberry Banana (with real fruit) – ~680 calories
All shakes are hand-mixed to order, so you can ask for light ice cream or no whipped cream to shave off 100–200 calories.
Final Verdict: Are Sonic Milkshakes Still Worth the Price in 2025?
At full price, a large Master Shake pushing $7–$8 feels steep compared to 2019 prices. However, when you factor in Happy Hour deals (turning that same shake into $3.50–$4) and the sheer quality and customization options, most fans agree Sonic still delivers one of the best fast-food milkshakes in America.
Next time the craving hits, check the clock, open the Sonic app, and you’ll likely pay half what the menu board shows.
