How Many Calories in Cranberry Juice? 5 to 140 Per Cup
On this page 6 sections
The mistake most people make is assuming all cranberry juice is the same. A bottle labeled “cranberry juice cocktail” can have twenty-eight times the calories of a diet version, and that gap matters if you’re managing blood sugar, tracking calories for weight loss, or choosing a daily drink.
The label tells you everything. Look for the words “100% juice,” the grams of added sugar, and the serving size, which is often smaller than the amount you pour.
How Many Calories Are in Cranberry Juice?
Cranberry juice calories range from about 5 to 140 per 8 oz, depending on the product. Calories in cranberry juice come mainly from added sugar: low-calorie versions have about 5–10 calories, unsweetened 100% juice about 45–50, and sweetened cocktail about 110–140.
For low calorie cranberry juice, start with the nutrition label rather than the front of the bottle. Sweetened cranberry cocktails commonly contain 20–28 g of added sugar per 8 oz, which accounts for most of their extra calories.
Read Three Lines on the Label
- Check the serving size. It may say 8 fl oz, 240 ml, or 1 cup; those are approximately the same amount. A 12 oz glass contains 1.5 servings if the label uses 8 oz.
- Read total sugars. This includes naturally occurring sugar from fruit juice plus sugar added during processing.
- Read added sugars. This line shows the sugar put into the drink. Zero means no added sugar, although the drink may still contain naturally occurring sugar.
| Type | Calories per 8 oz | Typical added sugar |
|---|---|---|
| Diet or zero-sugar cranberry drink | 5–10 | 0 g |
| 100% pure unsweetened cranberry juice | 45–50 | 0 g |
| Sweetened cranberry juice cocktail | 110–140 | 20–28 g |
A cranberry juice cocktail is usually a diluted cranberry drink with added sugar or a non-sugar sweetener. The word cocktail doesn’t mean alcohol, and it doesn’t tell you the calorie count by itself; the nutrition panel does.
A measured 150 ml pour is about 5.1 oz, so it has fewer calories than the listed 8 oz serving. As a rough guide, that is about 3–6 calories for a diet drink, 29–32 for unsweetened 100% juice, or 70–90 for a sweetened cocktail. A US pint is 16 fl oz, or two 8 oz servings.
Compare Calorie Counts Across Brands and Sizes
For common products, one cup of cranberry juice means 8 fl oz and contains about 5–140 calories; a 150 ml serving is roughly 3–90 calories, and a 16 oz pint is about 10–280 calories. A glass of cranberry juice has no fixed calorie count because its capacity and the drink’s formula both matter.
For a 150 ml serving of a cranberry drink from a juice machine or a brand such as Nestlé, use the product’s label: the type determines the answer, not the machine. The same 150 ml range is about 3–6 calories for diet, 29–32 for 100% unsweetened juice, and 70–90 for sweetened cocktail.
| Brand or format | Type | Listed size | Calories |
|---|---|---|---|
| Ocean Spray | Regular cranberry cocktail | 8 oz | About 110–120 |
| Ocean Spray | Diet cranberry drink | 8 oz | 5 |
| Ocean Spray | ZERO Sugar, sweetened with stevia | 8 oz | 10 |
| Ocean Spray | Sparkling Diet cranberry drink | 11.5 oz can | 10 |
| Any brand | 100% pure unsweetened cranberry juice | 8 oz | About 45–50 |
The 11.5 oz sparkling can has slightly more liquid than an 8 oz serving, but carbonation adds no calories. Its 10 calories come from the drink formula, so the larger can can still have a similar low calorie density to other diet cranberry drinks.
If you want a zero-sugar bottle for a 10-calorie serving, is Ocean Spray cranberry juice healthy is the related question to check next.
Know the Difference Between Diet and Zero Sugar Versions
Yes—the 5-calorie Ocean Spray cranberry drink can be a reasonable lower-calorie alternative to regular, but it isn’t identical. Both diet and zero-sugar versions replace sugar with non-caloric sweeteners; Ocean Spray Diet uses sucralose, while Zero Sugar uses stevia. The “low calorie” and “diet” names can vary by product, so check the label for sweetener and nutrition details.
Both drinks are diluted cranberry juice, so their cranberry content is similar and both contain compounds associated with urinary tract health. What those compounds do in the body is still being studied, and evidence for preventing infection is mixed. Removing sugar lowers calories and avoids the blood-glucose rise caused by sugar, but it also removes natural sugars and some vitamin C from the juice. Check the specific label: formulations can differ.
Taste is another difference: diet versions are generally less tart, and some people notice a slight stevia aftertaste in Zero Sugar. Once opened, refrigerate either kind and aim to use it within about 7–10 days.
If you want a fizzy, 10-calorie option for sipping instead of a still drink, the sparkling diet cans offer that format; they won’t provide the same amount of juice as a full glass.

If you’re reducing calories or managing blood sugar, a diet or zero-sugar cranberry drink can be a practical swap for sweetened cocktail. One 8 oz glass of sweetened cranberry cocktail every day adds about 800 calories a week, compared with about 35 calories for diet versions.
For diabetes or prediabetes, sweetened versions with 20–28 g of added sugar per 8 oz can raise blood glucose; diet and zero-sugar versions avoid that added sugar, though they may still contain 1–3 g of carbohydrates. If you count carbs, compare the label: sweetened varieties commonly have 25–35 g per 8 oz, while diet versions have about 1–3 g.
One 8 oz glass of sweetened cranberry cocktail can use most or all of the American Heart Association’s recommended daily added-sugar limit: about 25 g for women and 36 g for men. The label’s serving size matters; a large glass may hold more than 8 oz.
Dilute With Sparkling Water to Cut Calories Further
Yes, a cup of cranberry slushy made with diet juice, ice, and a blender can stay under 20 calories. For 100% unsweetened cranberry juice, adding sparkling water stretches the flavor while lowering calories per glass.
