Mustard is one of the most versatile condiments in the kitchen, adding tangy flavor for very few calories. But not every mustard is the same: yellow mustard, Dijon, whole grain, honey mustard, and spicy brown all have different calorie and carbohydrate profiles, especially when honey or sugar is added.
This mustard nutrition calculator lets you estimate the complete nutrition picture for any serving — choose your mustard type, enter the amount, and select a unit such as teaspoon, tablespoon, packet, or cup. It instantly calculates calories, protein, carbohydrates, fat, sugar, and sodium based on standard USDA values.
Whether you are tracking macros, following a low-carb diet, watching sodium, or simply curious about your favorite sandwich spread, this tool gives you a quick, practical answer in seconds.

How to Use This Tool
This calculator gives you a practical nutrition snapshot in four quick steps. First, choose the mustard type from the dropdown — yellow mustard is a good default because it is the most common table condiment. Next, enter how much mustard you want to use. The amount can be a whole number or a decimal, so values like 0.5 or 1.25 work fine. Select the unit that matches the recipe: teaspoon, tablespoon, packet, or cup. Then hit Calculate to see calories, protein, carbohydrates, fat, sugar, and sodium for that exact serving.
The quick-amount buttons are handy when you want a standard teaspoon, tablespoon, packet, or cup without typing. Press Reset to return to the default of 1 teaspoon of yellow mustard. If you need to scale a recipe between teaspoons and tablespoons, this simple conversion tool can help you keep the measurements straight.
How the Nutrition Numbers Are Calculated
The calculator uses standard reference values for prepared mustard, averaged from U.S. Department of Agriculture (USDA) food-composition data. Nutrition data on labels and in databases is almost always expressed per 100 grams, so the calculator first converts your selected serving into grams. Typical weights used here are: 1 teaspoon = 5 g, 1 tablespoon = 15 g, 1 packet = 5 g, and 1 cup = 245 g.
For example, if a mustard contains 66 calories per 100 g and you eat a 15 g tablespoon, the calories are 66 × 15 ÷ 100 = 9.9 kcal. The same mathematical logic is applied to every nutrient, so the results are consistent and easy to verify against the nutrition label on your jar.
Reference Nutrition Table (Per 100 g)
The table below shows the approximate values used in the calculator. Actual products can vary by brand, recipe, and preparation method.
| Mustard type | Calories | Protein (g) | Carbs (g) | Fat (g) | Sugar (g) | Sodium (mg) |
|---|---|---|---|---|---|---|
| Yellow | 66 | 3.7 | 6.0 | 3.3 | 0.9 | 1100 |
| Dijon | 70 | 3.4 | 5.8 | 3.9 | 0.9 | 1490 |
| Whole grain | 75 | 4.3 | 6.4 | 4.5 | 2.0 | 960 |
| Honey | 180 | 2.6 | 20.0 | 10.5 | 14.0 | 700 |
| Spicy brown | 60 | 3.0 | 5.0 | 3.0 | 0.6 | 1050 |
Worked Examples
Here are three common scenarios you can check with this calculator.
Tips & Common Mistakes to Avoid
- Watch the serving size. Honey mustard calories add up quickly, especially in dipping sauces and salad dressings.
- Know your packet. A typical restaurant mustard packet weighs 5–7 g, so a larger packet can mean 40% more calories and sodium than the values shown here.
- Use real teaspoons. Eyeballing a spoonful can double your serving; use an actual measuring spoon when you are tracking macros.
- Don't worry about net carbs in plain mustard. Yellow and Dijon mustards are very low in fiber, so total carbs and net carbs are nearly the same.
Frequently Asked Questions
Is mustard keto-friendly? Plain yellow and Dijon mustards are excellent low-carb choices. One teaspoon of yellow mustard contains only about 0.3 g of carbs, which fits easily into almost any keto or low-carb plan. Honey mustard, however, is not keto-friendly because of its added sugar.
Why is sodium so high in mustard? Mustard seeds need salt both for flavor and as a preservative. A single teaspoon of yellow mustard typically provides about 55 mg of sodium, which is modest, but larger servings or frequent use throughout the day can add up. If you are on a low-sodium diet, compare labels because Dijon and spicy brown varieties can differ noticeably.
How many calories are in one restaurant mustard packet? A typical 5 g packet of yellow mustard contains about 3 kcal, while a honey mustard packet is closer to 9 kcal because of added sugar and oil. This makes plain mustard a nearly free flavor booster for sandwiches, burgers, and marinades.
Can I use this for meal planning? Yes. The tool is helpful for building meal plans because it gives you the full macro profile for any portion. If you are also tracking your overall energy balance, this calorie-based weight-loss calculator can help you set a target that fits your mustard habit without guessing.
