Halibut is a lean, white fish prized for its mild flavor and firm texture. For anyone tracking macronutrients, knowing exactly how much fat is in a 100-gram portion is essential for meal planning, calorie budgeting, and hitting daily fat targets. This calculator lets you convert any weight of halibut into its fat content, with options for raw and cooked forms, plus a quick reference for common serving sizes.
Whether you're following a low-fat diet, counting macros, or simply curious about the nutritional profile of your dinner, this tool gives you instant, accurate numbers. You can also compare halibut to other popular fish and see how cooking method affects fat content. Use the preset buttons for quick estimates, or enter your exact portion to get a precise breakdown.

How to Use This Tool
Enter the weight of your halibut portion in grams, ounces, or pounds, select whether it's raw or cooked, and click Calculate Fat. The calculator instantly shows the total fat content, along with calories from fat and total calories. Use the quick-fill buttons for common serving sizes like 100 g or 4 oz to save time.
For the most accurate results, weigh your halibut before cooking if you're tracking raw values, or after cooking if you're tracking the cooked portion. The calculator uses standard USDA nutrition data for Atlantic and Pacific halibut.
Formula Explained
The fat content is calculated using the USDA FoodData Central values for halibut:
- Raw halibut: 1.6 g fat per 100 g
- Cooked halibut (dry heat): 2.9 g fat per 100 g
To find total fat, the calculator converts your weight to grams, then applies the formula:
Total fat (g) = (weight in grams ÷ 100) × fat per 100 g
Calories from fat are calculated by multiplying total fat by 9 (since each gram of fat provides 9 kcal). Total calories are estimated using the USDA values of 91 kcal per 100 g for raw and 111 kcal per 100 g for cooked halibut.
Worked Examples
Example 1: You have a 150 g raw halibut fillet. Total fat = (150 ÷ 100) × 1.6 = 2.4 g. Calories from fat = 2.4 × 9 = 21.6 kcal. Total calories ≈ 136.5 kcal.
Example 2: You have a 6 oz cooked halibut steak. First convert: 6 oz × 28.3495 = 170.1 g. Total fat = (170.1 ÷ 100) × 2.9 = 4.93 g. Calories from fat ≈ 44.4 kcal. Total calories ≈ 188.8 kcal.
Tips & Best Practices
- Weigh halibut raw for meal prep, then cook without added fats to keep the fat content close to the raw value.
- If you pan-fry or bake with oil or butter, add the fat from those ingredients separately.
- Halibut is naturally low in fat, making it an excellent choice for low-fat or high-protein diets.
- For macro tracking, remember that the cooked value includes moisture loss, so fat per 100 g is slightly higher.
Factors Affecting Accuracy
The fat content can vary slightly depending on the species (Atlantic vs. Pacific), the season, and the specific cut. Farmed halibut may have a slightly different profile than wild-caught. The USDA values used here are averages and should be accurate within about 10% for most portions.
If you're tracking for medical or strict dietary reasons, always check the nutrition label on packaged halibut or consult a registered dietitian.
Frequently Asked Questions
Is halibut a fatty fish?
No, halibut is considered a lean fish. It contains only about 1.6 g of fat per 100 g when raw, which is much lower than salmon (about 13 g per 100 g) or mackerel (about 13 g per 100 g).
Does cooking method change the fat content?
Cooking itself doesn't add fat, but it removes water, so the fat becomes more concentrated per 100 g. That's why cooked halibut shows a higher fat percentage. Adding oil, butter, or sauces will increase the total fat.
How does halibut compare to other white fish?
Halibut is similar to cod and haddock, all of which are very low in fat. For example, cod has about 0.7 g fat per 100 g raw, while halibut has 1.6 g. Halibut is slightly higher but still a lean choice.
Can I use this calculator for other fish?
No, this calculator is specifically calibrated for halibut. For other fish, use a dedicated calculator or check the USDA database. You might also find our salmon fat calculator useful for comparison.
