Fresh cranberries are surprisingly moderate in carbs for a fruit — roughly 12 g per 100 g — but dried, juiced, or sauced versions can contain far more. This Cranberry Carbs Per 100g Calculator lets you choose the cranberry product you are eating, enter a serving size in grams or ounces, and see total carbs, net carbs, fiber, and sugars instantly.
Weight-based tracking is the most reliable way to stay on target with low-carb, keto, diabetic, or calorie-conscious meal plans. Instead of guessing whether your handful of dried cranberries fits your daily allowance, the calculator uses standard USDA reference values to show exactly what you are consuming. An optional custom label mode lets you enter the values printed on your own package when they differ.
Use it for meal prep, recipe scaling, diabetic carb counting, or simply to understand how sweetened cranberry products compare to fresh fruit.

How the Calculation Works
The calculator uses nutrition values expressed per 100 g of edible portion. Your serving weight is converted to grams if needed (1 oz = 28.3495 g), then multiplied by the per-100 g value divided by 100. Net carbs are reported as total carbohydrate minus dietary fiber, because fiber is not digested and absorbed like other carbohydrates.
Reference Values Used
The preset values come from common USDA FoodData Central entries. Your product may differ, especially sweetened dried cranberries, juice cocktails, and homemade sauces.
| Product | Total carbs | Fiber | Sugars |
|---|---|---|---|
| Fresh / raw cranberries | 12.2 g | 4.6 g | 4.3 g |
| Frozen cranberries (unsweetened) | 12.2 g | 4.6 g | 4.3 g |
| Cranberry juice (unsweetened) | 8.4 g | 0.1 g | 7.4 g |
| Cranberry sauce (canned, sweetened) | 46.9 g | 1.0 g | 37.8 g |
| Dried cranberries (sweetened) | 82.8 g | 5.3 g | 65.0 g |
Worked Example
You eat 40 g of sweetened dried cranberries. Total carbs = 40 × (82.8 ÷ 100) = 33.1 g. Fiber = 40 × (5.3 ÷ 100) = 2.1 g, so net carbs = 33.1 − 2.1 = 31.0 g.
Using Custom Label Mode
If the package in your pantry lists different numbers, tick the custom label box and enter the total carbohydrate, fiber, and sugar values per 100 g. This is especially helpful for store-brand dried cranberries, no-sugar-added products, and homemade cranberry sauce where nutrition can vary considerably from the USDA averages.
Tips for Accurate Tracking
- Weigh your serving on a food scale instead of using volume measures — a “handful” can vary by 10–15 g.
- If the package lists values for a different serving size, convert to per 100 g or use the custom label mode in the calculator.
- Be cautious with “reduced sugar” dried cranberries; they can still contain 50–70 g of carbs per 100 g.
- For mixed holiday dishes, calculate the cranberry portion separately and add it to the rest of your meal.
Frequently Asked Questions
Are cranberries keto-friendly?
Fresh cranberries are relatively low in net carbs (about 7.6 g per 100 g) and can fit into a keto diet in small portions. Sweetened dried cranberries and cranberry sauce contain much more sugar and are harder to fit.
Why do nutrition labels show different numbers?
Manufacturers use different recipes, sweeteners, and fortification levels. The FDA allows small rounding differences, and “net carbs” is not a regulated term, so it is not printed on labels. The custom label mode in this tool lets you use the exact values from your package.
Does cooking change the carb content?
Cooking does not meaningfully change the carbohydrate or fiber content by weight, but it removes water, so a 100 g portion of cooked cranberries contains more fruit solids than 100 g of raw berries. Serving-size math is based on the prepared food you actually weigh.
