Sesame seeds may be tiny, but they pack a surprising amount of carbohydrate alongside healthy fats, protein, and fiber. A standard 100 g portion of whole sesame seeds contains roughly 23 g of total carbs, more than half of which comes from fiber, so the digestible net-carb count is considerably lower than the label total.
This sesame carb calculator works out the carbohydrate content in the amount you actually plan to eat. Choose a sesame product, enter a weight or household measure, and get total carbs, fiber, and optional net carbs in seconds. It is ideal for keto and low-carb dieters, people with diabetes, nutrition students, and anyone who wants more precise macronutrient tracking without weighing every ingredient for every meal.

Step-by-Step Guide
Start by choosing the sesame product you are using from the dropdown. The selected option changes the nutritional profile used in the calculation, because hulled seeds, toasted seeds, black seeds, and tahini all have slightly different carbohydrate and fiber values. Next, enter the amount you plan to eat. If you are weighing your portion, choose grams or ounces. If you are using measuring spoons, choose tablespoons or teaspoons. The calculator converts to grams using standard dense weights — 1 tablespoon of whole sesame seeds weighs about 9 g, 1 teaspoon about 3 g, and 1 cup about 144 g.
After you click Calculate, the tool shows three numbers: total carbohydrates, fiber, and net carbohydrates. Net carbs only appear when you check the Subtract fiber option; leaving it unchecked simply reports total carbs as your net figure, which is the approach some food labels use.
Example: You add 2 tablespoons of raw whole sesame seeds to a salad. The calculator uses 2 tbsp = 18 g, then applies 23.4 g total carbs and 11.8 g fiber per 100 g. That gives total carbs 4.21 g, fiber 2.12 g, and net carbs 2.09 g.
Carb Values Used in This Calculator
The values below are representative figures based on data published by the USDA FoodData Central for sesame seeds and tahini. Different harvests and processing methods can change the numbers by a gram or two, so if you are tracking strictly, check the nutrition label on your package and adjust accordingly.
| Sesame product | Total carbs (g/100g) | Fiber (g/100g) | Net carbs (g/100g) |
|---|---|---|---|
| Raw whole sesame seeds | 23.4 | 11.8 | 11.6 |
| Toasted sesame seeds | 25.0 | 12.0 | 13.0 |
| Black sesame seeds | 23.0 | 12.0 | 11.0 |
| Hulled sesame seeds | 21.0 | 10.5 | 10.5 |
| Tahini (sesame paste) | 21.0 | 9.0 | 12.0 |

How the Math Works
The calculation follows a simple three-step process. First, your chosen household measure is converted to grams using a fixed conversion factor. Second, the per-100g carbohydrate and fiber values from the selected product are divided by 100 to get a per-gram value. Third, that per-gram value is multiplied by the total weight of your portion.
Formula:
Total carbs = (carbs per 100 g / 100) × weight in grams
Fiber = (fiber per 100 g / 100) × weight in grams
Net carbs = total carbs − fiber (when subtract-fiber mode is on)
Because the calculator works from weight rather than volume, the result is accurate as long as your conversion factor reflects the density of the food. Tahini, for example, is heavier per tablespoon than whole seeds, so using a scale for tahini is the safest approach.
Net Carbs: Total vs. Digestible Carbs
Total carbohydrates include fiber, which your body does not fully digest. Net carbs is a popular term used in low-carb and keto meal planning to estimate the carbohydrates that significantly affect blood sugar. For sesame seeds, this distinction matters a lot: more than half of the carbohydrate in raw whole seeds is fiber. A 100 g portion of raw sesame seeds has about 23 g of total carbs but only about 11 to 12 g of net carbs.
Keep in mind that different authorities define net carbs differently. Some subtract only fiber, while others also subtract sugar alcohols. The calculator uses the simple fiber-subtraction method, which is the standard for whole foods like seeds.
Tips for Accurate Tracking
Use a digital kitchen scale for the best accuracy, especially for tahini. Volume conversions for seeds are approximate, and spoon dimensions vary. When eating sesame-based products like hummus, granola, or packaged sesame crackers, remember that the sesame seeds are only part of the carbohydrate total; the other ingredients also count. For products with added sugar or flour, always rely on the package label rather than this calculator.
Pro tip: Toasted sesame seeds have a slightly lower moisture content and may read a little higher in carbs by weight than raw seeds. If you are weighing toasted seeds after toasting, use the toasted option in the calculator.
Frequently Asked Questions
Are sesame seeds keto-friendly? Yes, in normal serving sizes. A 28 g serving (about 1 oz) of raw sesame seeds has roughly 6.5 g total carbs and about 3.3 g net carbs, which fits comfortably into most low-carb meal plans. Because they are calorie-dense, portion control still matters.
How many carbs are in one tablespoon of sesame seeds? One tablespoon of whole sesame seeds weighs about 9 g. That equals about 2.1 g total carbs and 1.0 g net carbs for raw whole seeds. Add about 0.1 to 0.2 g if you use the toasted option.
Does toasting change the carb count? Toasting removes moisture, so the same weight of toasted seeds contains a slightly higher proportion of carbs, protein, and fat. The difference is small but visible in the calculator.
Is tahini lower in carbs than whole seeds? Tahini has about 21 g of total carbs per 100 g, compared with roughly 23 g for whole raw seeds. It also contains slightly less fiber, so the net carb difference is smaller than the total carb difference. For another per-100g carb comparison, try our apple carbs per 100g calculator.
