How the Calories Add Up in Your 16oz Slushie
The calorie content of a 16oz slushie is not a single, fixed number. It is primarily influenced by the amount of sugar syrup used, which in turn depends on the brand, the specific flavor, and whether it's a diet or sugar-free version. The bulk of a slushie is crushed ice, which is calorie-free, but the flavor syrup is where all the energy content originates. For instance, a basic blue raspberry flavor from one vendor might have a different calorie count than a cherry flavor from another, even for the same 16oz size.
Brand-Specific Calorie Counts
Different fast-food chains, convenience stores, and retailers have their own proprietary slushie mixes, each with its unique nutritional profile. Here’s a look at the estimated calorie ranges for a 16oz serving from a few popular vendors, highlighting how much variation exists:
- Sonic Drive-In: A medium (20oz) cherry slush contains 290 calories, making a 16oz size likely in the range of 230-240 calories. A plain slush (without syrup) is significantly lower, illustrating the impact of the added sugar syrup.
- Fosters Freeze: A 16oz blue raspberry slush is reported to contain 270 calories, with 100% of the macronutrients coming from carbs.
- Slurpee (7-Eleven): A 16oz Pepsi-flavored Slurpee reportedly contains about 110 calories, significantly less than a bottled Pepsi of the same size, due to the ice content.
- ICEE: A small (16oz) ICEE from Pretzelmaker has 130 calories and 36g of sugar, indicating that some standard, non-diet options can be on the lower end of the spectrum.
- Sno Biz: A 16oz standard flavor contains 288 calories, while a sugar-free version has a mere 16 calories.
What About the Sugar?
Because slushies are made primarily from frozen, flavored sugar water, the sugar content is directly correlated with the calorie count. For example, a standard 16oz Sno Biz slushie has 72g of sugar, which accounts for virtually all of its 288 calories. High sugar intake is linked to various health concerns and is something to consider when enjoying this sweet treat. For those seeking to reduce their sugar intake, opt for diet or sugar-free versions, which replace regular sugar with artificial or non-caloric sweeteners.
Making Healthier Slushie Choices
If you're concerned about the high sugar and calorie content of store-bought slushies, you have healthier alternatives. Making your own at home provides full control over the ingredients:
- Use fruit and natural sweeteners: Blend frozen fruit chunks (like watermelon or berries) with a calorie-free sweetener or a small amount of honey for a more nutritious, naturally flavored slushie.
- Combine frozen fruit with juice: Blend frozen fruit with 100% fruit juice for a slushie with more vitamins and fiber than a typical store-bought version.
- Choose sugar-free options: Many places offer sugar-free slushie options that use low-calorie sweeteners, drastically cutting the calorie count.
- Opt for smaller sizes: The easiest way to reduce calorie intake is to simply choose a smaller portion. The 16oz is a common size, but many places offer 12oz or 8oz options.

The Bottom Line
A 16oz slushie can contain anywhere from 110 to nearly 300 calories, with most of that energy coming from added sugar syrup. The brand, flavor, and any additional toppings are the most important factors influencing the final nutritional information. While a standard slushie is high in sugar and offers minimal nutritional value, there are lower-calorie versions available. You can also take control by making your own at home using frozen fruit and natural sweeteners. This allows for a refreshing treat without the excessive sugar content.

Conclusion
In conclusion, while a 16oz slushie is a classic frozen treat, its calorie and sugar content can be substantial, depending largely on the retailer and flavor. The range is wide, from as low as 110 calories for a diet option to almost 300 for a standard sugar-heavy variety. By understanding these variations and opting for sugar-free versions or healthier homemade alternatives, you can still enjoy a refreshing slushie without a massive caloric load.
