Salmon is famous for its healthy fat profile, but the amount of fat varies widely by species and production method. Farmed Atlantic salmon can pack more than twice the fat of wild sockeye, which changes calories, satiety, and omega-3 intake. This calculator converts your serving size into a practical fat breakdown for eight types of salmon, from farmed fillets to canned and smoked products, using USDA reference values scaled to your exact portion.
The tool is useful for macro trackers, keto dieters, meal planners, and anyone curious about the nutritional differences between salmon varieties. Results show total fat, saturated, monounsaturated, and polyunsaturated fat, omega-3 EPA + DHA, calories from fat, and percent daily value based on a 2,000-calorie reference diet. You can also add a teaspoon of butter or oil to see how preparation changes the numbers, so you can compare varieties side by side without pulling up separate nutrition tables.

📊 Your Fat Breakdown
Quick Start
Choose the salmon type that matches your fillet, enter a serving size in grams or ounces, pick an optional cooking fat if you plan to pan-sear or bake with butter or oil, then press Calculate Fat. The results panel shows total fat, saturated, monounsaturated, and polyunsaturated fat, omega-3 EPA + DHA, calories from fat, and the percent daily value based on a 2,000-calorie reference diet.
The preset buttons are handy for common portion sizes: 100 g, 150 g, 4 oz, and 6 oz. A typical restaurant fillet is about 6 oz, while a home-cooked portion is often 4-6 oz. If you are meal-prepping, weighing the raw fillet before cooking gives the most consistent results.
If you prepare salmon with butter, olive oil, or avocado oil, include it in the calculation. One teaspoon of cooking fat adds roughly 4.5 g of fat and about 40 kcal, which can shift your daily macro totals by a noticeable amount.
Worked Examples
Example 1: Farmed Atlantic fillet, 170 g (about 6 oz), no added fat. Farmed Atlantic salmon contains 13.4 g fat per 100 g, so 170 g provides 13.4 × 1.7 = 22.8 g total fat, of which 4.8 g is saturated, 7.5 g is monounsaturated, 6.5 g is polyunsaturated, and about 4.3 g is omega-3 EPA + DHA. Calories from fat = 22.8 × 9 = 205 kcal, which is roughly 29% of the 78 g daily value for total fat.
Example 2: Wild sockeye fillet, 150 g (about 5.3 oz), cooked with 1 tsp olive oil. Wild sockeye contains 5.6 g fat per 100 g, so the base is 5.6 × 1.5 = 8.4 g. Adding 4.5 g of olive oil brings total fat to 12.9 g, with about 2.0 g saturated fat. Calories from fat are 116 kcal, and omega-3 EPA + DHA is roughly 1.7 g. Notice that farmed salmon still supplies more total fat and omega-3s than wild salmon even when the wild fillet is cooked with added oil.
How the Numbers Are Calculated
Each entry in the tool uses a per-100 g fat profile based on values published by the USDA FoodData Central for raw Atlantic salmon, sockeye salmon, chinook, coho, pink, chum, smoked salmon, and canned salmon. The calculator converts your serving to grams, applies the per-100 g ratio, and then adds the selected cooking fat.
Three derived values deserve explanation:
- Calories from fat use the standard Atwater factor of 9 kcal per gram of fat.
- Percent daily value uses 78 g of total fat per day, the reference amount for a 2,000-calorie diet set by the FDA.
- Omega-3 EPA + DHA is the sum of eicosapentaenoic acid and docosahexaenoic acid, the two long-chain omega-3s most strongly linked to heart health; the tool does not include plant-based ALA.
Fat values for raw salmon concentrate slightly when cooked because moisture is lost, but the fat totals in this tool stay close to cooked values for pan-seared or baked fillets. If you eat salmon raw in sushi or poke bowls, the raw values apply directly.
Reference Fat Content per 100 g
| Salmon Type | Total Fat (g) | Sat. Fat (g) | Omega-3 EPA + DHA (g) |
|---|---|---|---|
| Farmed Atlantic | 13.4 | 2.8 | 2.5 |
| Wild Sockeye | 5.6 | 0.9 | 1.1 |
| Wild Chinook | 10.4 | 2.1 | 2.1 |
| Coho | 7.5 | 1.2 | 1.5 |
| Pink | 4.2 | 0.8 | 0.8 |
| Chum | 5.6 | 1.3 | 0.9 |
| Smoked | 4.4 | 1.0 | 0.6 |
| Canned | 6.1 | 1.4 | 1.2 |
Values are rounded from USDA entries and reflect edible raw portions. Canned salmon values represent fish packed in water; oil-packed versions will run higher.
Factors Affecting Accuracy
Salmon is a natural product, so the numbers vary from one fillet to the next. Wild-caught fish reflect the season, ocean conditions, and the individual fish's migration; farmed fish depend on the feed formulation, which producers adjust over time. Smoked salmon can also vary with the curing method and whether it is made from farmed or wild fish.
For macro tracking, weighing raw fillets is the most reliable approach because defrosting, trimming, and cooking all change water content. A frozen fillet can weigh more than the same fillet once thawed and patted dry.
Frequently Asked Questions
Why does farmed salmon have more fat than wild salmon? Farmed salmon receive a controlled, energy-dense diet and move less than wild fish, so their flesh stores more total fat. Because much of that fat is omega-3 rich, farmed Atlantic salmon often delivers more EPA + DHA per serving than leaner wild species.
Does cooking change the fat content? Salmon loses water and a small amount of fat during cooking, but the changes are modest. If you cook without added fat, the totals remain close to the raw values shown here.
Are omega-3 values the same for every fillet? No. Season, diet, and processing cause natural variation. The NIH Omega-3 Fact Sheet describes how farming practices and feed formulations influence EPA and DHA levels in fish.
Is salmon fat mostly unsaturated? Yes. In most varieties, roughly 60-70% of the fat is unsaturated. The saturated portion is small, which is one reason salmon is often recommended as part of a heart-healthy eating pattern.
Use this tool for meal planning and education, not as medical advice. If you are adjusting fat intake for a medical condition or have questions about omega-3 supplementation, talk with your doctor or a registered dietitian.
