Dates are one of the most carbohydrate-dense whole fruits, making them a favorite quick energy source for athletes and a natural sweetener in baking. But their carb content varies noticeably by variety, ripeness, and whether they are fresh or dried. This calculator lets you estimate the total carbohydrates and net carbs per 100 grams of dates, with options to adjust for moisture level and portion size.
Whether you are tracking macros, following a low-carb or ketogenic diet, or simply curious about the nutritional profile of Medjool versus Deglet Noor dates, this tool gives you a clear breakdown. You can also convert your result to other serving sizes, such as a single date or a cup of chopped dates, making it easier to log accurately in your favorite calorie-tracking app.
Use the preset buttons for common date varieties, or enter your own values if you have specific nutrition data. The calculator also shows the fiber and sugar components, so you can see exactly where the carbs come from.

Step-by-Step Breakdown
How to Use This Tool
Start by selecting a date variety from the dropdown — Medjool, Deglet Noor, or fresh dates. The calculator will automatically fill in typical values for total carbohydrates, fiber, and sugars per 100 grams. You can also choose "Custom values" and enter your own numbers if you have specific nutrition data from a label or a trusted database.
Next, set your portion size. You can enter grams, ounces, whole dates, or cups of chopped dates. The calculator converts your portion to grams using standard approximations: one whole date weighs about 24 grams, and one cup of chopped dates weighs about 160 grams. If you prefer to work in ounces, it uses the conversion 1 ounce = 28.3495 grams.
Click Calculate to see the results. The output shows total carbs, net carbs, fiber, and sugars per 100 grams, plus the corresponding amounts in your chosen portion. A step-by-step breakdown explains how each number was derived, which is helpful if you want to verify the math or adjust for your own data.
Formula Explained
The core calculation is straightforward: Net Carbs = Total Carbohydrates − Dietary Fiber. This is the standard method used by many low-carb and ketogenic dieters, because fiber is not digested and does not raise blood sugar in the same way as other carbohydrates. Some people also subtract sugar alcohols, but dates contain negligible amounts, so we keep it simple.
For portion conversion, the calculator uses a proportional scaling factor: Factor = Portion Weight (g) ÷ 100. Then it multiplies the per-100g values by this factor. For example, if you eat 50 grams of dates, the factor is 0.5, so you get half the carbs of the 100g reference.
The typical values used for the presets come from the USDA FoodData Central database. Medjool dates have about 75 g carbs, 6.7 g fiber, and 66.5 g sugars per 100g. Deglet Noor dates are slightly lower, with about 72 g carbs, 6.4 g fiber, and 63.4 g sugars. Fresh dates, which contain more water, have only about 33 g carbs, 3.6 g fiber, and 27 g sugars per 100g.
Worked Examples
Example 1: You eat two Medjool dates, each weighing about 24 grams, so your portion is 48 grams. Using the Medjool preset (75 g carbs, 6.7 g fiber per 100g), the factor is 0.48. Total carbs = 75 × 0.48 = 36 g. Net carbs = (75 − 6.7) × 0.48 = 68.3 × 0.48 = 32.8 g. So your snack provides roughly 36 g of total carbs and 33 g of net carbs.
Example 2: You want to use 1 cup of chopped Deglet Noor dates in a recipe. One cup weighs about 160 grams. Using the Deglet preset (72 g carbs, 6.4 g fiber), the factor is 1.6. Total carbs = 72 × 1.6 = 115.2 g. Net carbs = (72 − 6.4) × 1.6 = 65.6 × 1.6 = 105 g. This shows why dates are so energy-dense — a single cup can contain over 100 grams of net carbs.
Tips & Best Practices
- Weigh your dates for accuracy. Whole dates vary in size; a small Deglet can weigh 15 grams, while a large Medjool can weigh 30 grams or more.
- Check the label if you buy packaged dates. Some brands add sugar or other ingredients, which changes the carb content.
- Consider ripeness. As dates ripen, their sugar content increases and moisture decreases, so the carb density rises.
- Use net carbs for keto, but remember that dates are still very high in sugar. Even a small portion can use up a large part of your daily carb allowance.
- For baking, remember that dates are often used as a sweetener substitute. One cup of chopped dates can replace about one cup of sugar in some recipes, but you'll need to adjust liquids because dates add moisture.
Factors Affecting Accuracy
The preset values are averages from the USDA database, but actual values can vary by growing region, harvest year, and processing. Dried dates have had most of their water removed, which concentrates the carbohydrates. Fresh dates, on the other hand, contain more water and therefore fewer carbs per 100 grams.
Another factor is the definition of "net carbs." Some people subtract both fiber and sugar alcohols, but since dates contain no significant sugar alcohols, the difference is minimal. Also, the fiber value can vary slightly depending on the analytical method used. For most purposes, the USDA values are reliable enough for meal planning.
If you are tracking macros for medical reasons, such as diabetes, consult a registered dietitian or use a continuous glucose monitor to see how your body responds to dates. Individual glycemic responses can vary.
Frequently Asked Questions
Are dates keto-friendly? No, dates are very high in sugar. A single Medjool date contains about 18 grams of net carbs, which is more than many people's entire daily carb allowance on a strict ketogenic diet.
What is the glycemic index of dates? The glycemic index of dates varies by variety, but it is generally moderate to high, ranging from about 42 to 55. Despite the high sugar content, the fiber and certain compounds may slow absorption slightly.
Can I eat dates if I have diabetes? It depends on your individual blood sugar control. Because dates are so carb-dense, portion control is essential. A small date or two may be acceptable for some people, but it's best to test your blood sugar response and consult your healthcare provider.
How many carbs are in one date? Using the average weight of 24 grams per date and the Medjool values, one date has about 18 grams of total carbs and 16.4 grams of net carbs. For Deglet Noor, it's about 17.3 grams total and 15.7 grams net.
What is the difference between total carbs and net carbs? Total carbs include all carbohydrates, including fiber. Net carbs subtract fiber because it is not digested. For dates, the difference is about 6-7 grams per 100g, which is relatively small compared to the total.
