Plums are a juicy, low-calorie fruit packed with fiber, vitamin C, and antioxidants. Whether you’re tracking your daily intake, meal prepping, or simply curious about the nutritional value of fresh plums, this calculator gives you a quick and accurate estimate of calories, carbohydrates, and fiber based on the weight and type of plum you’re eating.
This tool is ideal for anyone following a calorie-controlled diet, a low-carb or keto lifestyle, or just looking to make healthier snack choices. Simply enter the weight of your plum (or use the quick-fill presets for common sizes), select the plum type (fresh, canned, or dried/prune), and get an instant breakdown of calories, carbs, and fiber. You can also adjust for the number of plums to scale your results.

How to Use This Tool
Using the Plum Calorie Calculator is straightforward. Start by entering the weight of a single plum in grams or ounces. If you don't have a scale, use the preset buttons for small (66g), medium (100g), or large (150g) plums. Next, select the plum type: fresh, canned (in syrup), or dried (prune). Finally, enter the number of plums you plan to eat. Click "Calculate" to see the total calories, carbohydrates, and fiber for your portion. The result also shows the per-plum calorie count for easy reference.
Nutritional Values & Formula Explained
The calculator uses standard USDA nutritional data per 100 grams for each plum type. Fresh plums are low in calories (46 kcal/100g) and provide a modest amount of fiber (1.4g) and natural sugars. Canned plums in syrup have added sugar, raising the calorie count to 63 kcal/100g and carbs to 16.3g. Dried plums (prunes) are much more energy-dense at 240 kcal/100g, with 63.9g carbs and 7.1g fiber — making them a concentrated source of energy and fiber.
The formula is simple: (nutritional value per 100g × total weight in grams) / 100. For example, a 100g fresh plum provides 46 kcal, 11.4g carbs, and 1.4g fiber. If you eat two such plums, double those values.
Worked Examples
Common Mistakes to Avoid
- Confusing plum types: Fresh, canned, and dried plums have very different calorie densities. Always select the correct type.
- Ignoring serving size: The calculator asks for weight per plum and number of plums. If you enter the total weight directly, set the count to 1.
- Using volume instead of weight: Plums vary in size and density. Weighing is far more accurate than estimating by volume.
- Forgetting to convert units: If you enter weight in ounces, the calculator automatically converts to grams. Double-check your unit selection.
Frequently Asked Questions
Are plums keto-friendly? Fresh plums contain about 11.4g carbs per 100g, which is moderate. A small plum (66g) has about 7.5g carbs, so it can fit into a keto diet in limited amounts. Dried plums are much higher in carbs and are not recommended for keto.
How many calories are in a single plum? A medium fresh plum (100g) has about 46 calories. A small plum (66g) has about 30 calories, and a large plum (150g) has about 69 calories.
Do canned plums have added sugar? Yes, most canned plums are packed in heavy syrup, which adds significant sugar and calories. Look for "no added sugar" or "in juice" varieties if you want a lower-calorie option.
Are prunes good for digestion? Yes, prunes are well-known for their high fiber content (7.1g per 100g) and natural laxative effect. They are often recommended for constipation relief.
