Cranberries are celebrated for their tart flavor, colorful dishes, and vitamin C content, but when you are tracking protein, they may not be the first food that comes to mind. This calculator makes it easy to find out exactly how much protein is in your cranberry serving — whether you are eating fresh berries, dried sweetened cranberries, drinking unsweetened juice, or serving canned sauce.
Select a cranberry product, adjust the protein and calorie values if your label differs, enter how much you plan to eat, and the tool instantly shows protein grams, calories, protein density, and how that fits into your daily protein target. Dietitians, meal planners, and anyone counting macros will appreciate how quickly a serving can be converted to a per-100g nutrition estimate before adding it to a food log.
🍒 Cranberry Protein Per 100g Calculator
Find protein in your cranberry serving — quickly convert serving weight to protein grams using typical values or your own nutrition label.
This selection fills in typical protein and calorie values. You can edit them in step 2 if your product differs.
How to Use This Tool
Start by choosing the cranberry product you are eating. The calculator fills in typical protein and calorie values per 100 g from widely used USDA nutrition references. You can edit those values if your package label gives different numbers — this makes the tool work for any brand or homemade preparation.
Next, enter your serving size. You can type grams directly or switch to ounces, and the calculator converts automatically. If you are logging meals, the optional daily protein target turns the output into a quick percentage, so you can see whether a handful of dried cranberries makes a meaningful contribution to your daily protein intake. Press Calculate Protein to generate your results and the short math breakdown behind them.
The Math Behind the Conversion
All nutrition calculations in this tool use the same simple proportion. If a food contains P grams of protein per 100 g, then a serving of S grams gives:
Protein (g) = (P ÷ 100) × S
The same rule applies to calories: Calories = (C ÷ 100) × S, where C is the calorie value entered per 100 g. This linear proportion is valid because the calculator assumes the product is nutritionally uniform. In practice, whole cranberries can vary slightly with harvest, moisture, and added sweeteners, which is why the protein and calorie inputs are editable.
Protein density is simply the fraction of the food's weight that comes from protein: density (%) = protein (g) ÷ serving weight (g) × 100. For fresh cranberries this value is very small — around 0.4% — which is normal for most fruit. Fruits are typically valued more for fiber, vitamin C, and phytochemicals than for protein.
Worked Examples
Example 1: A 100 g bowl of fresh cranberries.
Select “Raw / fresh cranberries,” enter 100 g, and calculate. Using 0.39 g protein per 100 g:
Protein = (0.39 ÷ 100) × 100 = 0.39 g.
Calories = (46 ÷ 100) × 100 = 46 kcal.
Protein density = 0.39 ÷ 100 × 100 = 0.39%.
Example 2: A 40 g snack of dried sweetened cranberries.
Select “Dried sweetened cranberries,” enter 40 g, and calculate. With 0.20 g protein per 100 g:
Protein = (0.20 ÷ 100) × 40 = 0.08 g.
Calories = (325 ÷ 100) × 40 = 130 kcal.
This explains why dried cranberries contribute quick energy but almost no protein to a trail mix.
Reference: Typical Values for Cranberry Products
| Product | Protein (g / 100 g) | Energy (kcal / 100 g) |
|---|---|---|
| Raw / fresh cranberries | 0.39 | 46 |
| Frozen cranberries | 0.40 | 46 |
| Dried sweetened cranberries | 0.20 | 325 |
| Cranberry juice, unsweetened | 0.20 | 46 |
| Cranberry sauce, canned sweetened | 0.20 | 151 |
Values are rounded estimates based on typical USDA FoodData Central profiles for nutrient comparison. Always prefer the nutrition label on the package you are using, especially for dried and sweetened products, because added sugar changes both calories and protein percentages.

Tips & Best Practices
If you are pairing cranberries with a protein source — for example, adding dried cranberries to Greek yogurt, chicken salad, or a protein smoothie — remember that the cranberry's protein contribution will be minimal. Use this calculator to log the fruit accurately, then focus on the yogurt, meat, or protein powder for most of your grams. This approach is part of a healthy eating pattern that prioritizes nutrient-dense foods without ignoring carbohydrate-rich fruit.
Frequently Asked Questions
Do cranberries contain enough protein to count toward my daily target?
No single serving of cranberries provides a meaningful amount of protein. A 100 g portion of raw cranberries gives only about 0.39 g — less than 1% of a typical 50 g daily target. Cranberries are still a healthy fruit choice, but they are not a protein food.
Why does dried cranberry show more calories but less protein per 100 g?
Drying removes water and concentrates natural sugars; sweetened dried cranberries then have added sugar and sometimes oil. The calorie density climbs from about 46 kcal/100 g in raw fruit to 300–350 kcal/100 g in dried form, while protein stays roughly the same or becomes slightly diluted on a per-100 g weight basis.
Can I use this calculator with a homemade cranberry sauce recipe?
Yes. Choose any product, then edit the protein and calorie fields in step 2 to match your recipe estimate. If your recipe serves six people and contains 0.5 g protein total in the cranberries, each serving would provide about 0.08 g before you add the sugar and other ingredients.
Is cranberry juice a meaningful source of protein?
No. Unsweetened cranberry juice has around 0.2 g protein per 100 g, and many commercial juice blends are mostly water and added sugar. The vitamin C content is often more interesting than the protein profile; cranberry vitamin C calculator helps with that nutrient instead.
