The Mustard Fat Per 100g Calculator is a quick nutrition tool for anyone tracking fat, calories, or macros in condiments. Mustard is often seen as a “zero-calorie” condiment, but many prepared mustards contain oil, seeds, and other fat sources that can add up. This calculator helps you find the fat content per 100 grams based on the mustard type or your jar’s nutrition label.
Use the preset buttons for yellow, Dijon, whole grain, honey, and spicy brown mustard, or enter your own value from a label. Then enter how much you ate in grams, tablespoons, or teaspoons. The tool converts your portion to grams, works out the fat in that serving, shows the calories from fat, and compares it to a daily reference value.
This calculator is especially useful for diet planning, macro counting, and anyone who wants a clearer picture of what condiments contribute to their daily fat intake.

Quick Start
Open the calculator, pick a mustard type or enter your own fat value per 100 g, then type how much you ate. The amount can be in grams, tablespoons, or teaspoons; the calculator handles the unit conversion for you. If your jar’s label lists fat per serving, use the label converter in Step 1 to turn that into fat per 100 g, then click Calculate fat.
Typical Fat Values in Common Mustards
The fat content of prepared mustard depends on the seeds, oil, and other ingredients. The preset values in this calculator are reasonable starting points, but always check the jar when precision matters. USDA FoodData Central lists many mustard products; a typical yellow mustard has about 3.3 g of fat per 100 g, while restaurant-made honey mustard or specialty whole-grain blends can be 10 g or more. The safest approach is to use the label value from the exact jar you own. You can search official entries at USDA FoodData Central.
| Mustard type | Typical fat per 100 g | Why it varies |
|---|---|---|
| Yellow / American | 3.3 g | Water, vinegar, turmeric, small amounts of mustard seed |
| Dijon | 4.0 g | White wine, mustard seed, sometimes a little oil |
| Whole grain | 5.2 g | Visible seeds retain more of the seed’s natural oil |
| Honey mustard | 6.8 g | Honey and often oil or mayonnaise base |
| Spicy brown | 4.4 g | Coarse ground seeds and spices |
How Fat Per 100g Is Calculated
When you have a label that lists fat per serving, use this ratio:
Fat per 100 g = (fat per serving ÷ serving size in g) × 100
Once you know the fat per 100 g, the tool calculates your portion’s fat with:
Portion fat = amount eaten in g × (fat per 100 g ÷ 100)
Every gram of fat provides about 9 kilocalories, so the calculator multiplies the portion fat by 9 to show the calories coming from fat. It also compares the result against a daily reference value of 78 g of fat for a 2,000-calorie diet, which is the standard nutrition-fact label benchmark.
Label Conversion: A Worked Example
Imagine a jar of whole-grain mustard lists a serving size of 1 teaspoon (5 g) and 0.26 g of fat per serving.
Fat per 100 g = (0.26 ÷ 5) × 100 = 5.2 g.
If you make a sandwich with 2 tablespoons of mustard, that equals 30 g. The calculator converts tablespoons to grams using 1 tbsp ≈ 15 g, then finds:
Portion fat = 30 × (5.2 ÷ 100) = 1.56 g.
Calories from fat = 1.56 × 9 = 14.0 kcal.
It may not sound like much, but small condiments appear several times a day. Tracking them can close the gap between estimated and actual fat intake.
Tips for Tracking Fat Accurately
Weigh your mustard. A food scale gives the most accurate gram count. Measuring spoons can vary by 1–2 g depending on how heaped the spoon is, which matters when a serving is only 5–15 g.
Read the label per 100 g vs per serving. Some brands list fat per 100 g directly; others only per serving. The label converter in this tool avoids the mental math.
Be careful with honey mustard and light mustards. Honey mustard can contain added oil and sugar; light or fat-free styles may have near-zero fat but extra sodium or sweeteners. Check the ingredient list and nutrition facts, not just the front label.
Frequently Asked Questions
Is mustard high in fat?
Prepared yellow mustard is very low in fat when eaten in normal amounts. A typical 5 g teaspoon of yellow mustard has about 0.17 g of fat. Mustard seeds themselves are fat-rich, but the condiment uses them sparingly. Whole-grain and Dijon varieties are somewhat higher because more seed material remains.
Why does the same mustard type show different fat per 100 g?
Manufacturers use different seed-to-liquid ratios, added oils, wine, and emulsifiers. A strongly seeded artisan mustard can have 8–12 g of fat per 100 g, while a mass-market yellow mustard may have just 3 g. National food databases and brand listings show this range clearly.
How many calories from fat are in a tablespoon of yellow mustard?
If yellow mustard has 3.3 g fat per 100 g and one tablespoon weighs about 15 g, then one tablespoon contains roughly 0.5 g of fat and about 4.5 kcal from fat. The total calories in a tablespoon are around 10–15 kcal because of carbohydrates and protein, not fat.
