Anchovies are small but surprisingly rich in fat, and the amount depends heavily on how they are prepared. Raw anchovies are relatively lean, while oil-packed fillets absorb oil and can contain two to three times more fat. This calculator converts any portion size into fat per 100g, total fat per serving, calories from fat, and a daily value percentage.
It is useful for anyone tracking macros on a keto, low-carb, heart-healthy, or general calorie-conscious eating plan. Pick your anchovy type, adjust the fat value if your label differs, enter the portion in grams or ounces, and click calculate. A step-by-step breakdown shows exactly how the number was reached.
Daily value figures use the FDA reference of 78g total fat for a 2,000-calorie diet; your personal target may differ.

Quick Start
Choose the anchovy type that matches your can or jar, then use the preset fat value or overwrite it with the number printed on your nutrition label. Enter how much you plan to eat in grams or ounces, set the number of servings, and click Calculate fat. The result card shows total fat for the whole portion, fat per 100 g, calories from fat, and the share of the FDA daily value for total fat.
If you are logging a single fillet rather than a whole can, use the one-fillet quick-fill button and adjust to the actual weight when the label states something different. The same method works for recipes: add up each anchovy portion separately or enter the combined weight once.
Formula Explained
All nutrition label values are based on a 100 g reference amount, so the calculation always resolves to that baseline. Start with the fat value per 100 g, convert your portion to grams, and apply fat = (fat per 100 g × portion weight in g) ÷ 100. When you select ounces, the program multiplies by 28.3495 to convert to grams first. Calories from fat use the food-energy constant of 9 kcal per gram of fat. Daily value is calculated against the FDA's 78 g reference for total fat in a 2,000-calorie daily diet.
If your can label lists fat per serving instead of per 100 g, divide the label fat by the label serving weight in grams and multiply by 100 before entering it. Example: a serving of 28 g with 2.7 g of fat works out to (2.7 ÷ 28) × 100 = 9.6 g per 100 g.
Worked Example
Suppose you eat one can of drained oil-packed anchovies containing 45 g of fish and the label states 9.7 g of fat per 100 g. The math is (9.7 × 45) ÷ 100 = 4.37 g of fat. That fat contributes about 39 kcal (4.37 × 9), which is roughly 5.6% of the 78 g daily fat reference. If you instead eat 100 g of raw anchovy at 4.84 g fat per 100 g, total fat is 4.84 g and calories from fat drop to about 44 kcal. This illustrates why preparation method matters more than portion size for moderating fat intake.
Reference Data
| Anchovy type | Typical fat (g per 100 g) |
|---|---|
| Raw, European anchovy | 4.8 |
| Canned in oil, drained | 9.7 |
| Canned in tomato sauce | 6.0 |
| Dried / salt-cured | 10.5 |
| Canned in oil, not drained | 10–14 depending on oil |
Values are representative USDA composition figures compiled from USDA FoodData Central. Brand, packing medium, draining technique, and fish size can move the real number by one to three grams.
Tips & Best Practices
Use the exact weight when you have a kitchen scale; volume estimates are unreliable for irregular fillets. Drain canned anchovies thoroughly on paper towels before weighing if you want to match the drained preset. For meal planning, compare the fat per 100 g of different anchovy products rather than comparing whole cans of different sizes, because can weight varies widely.
For keto or low-carb plans, anchovies are attractive because the fat is mostly unsaturated and the carbohydrate content is negligible. Still, track the fat against your personal macro target rather than the 78 g reference, which is simply the FDA label benchmark for a generic 2,000-calorie diet.
Common Mistakes to Avoid
The most common error is treating undrained oil-packed anchovies as if they were the drained product. The oil clinging to the fillets adds several grams of fat per serving. Another frequent mistake is entering the fat value for a different preparation: raw anchovy values are roughly half those of oil-packed fillets, so confusing the two can under-report your intake by a meaningful margin.
Also check whether a label says drained or with oil. Some cans list fat for the entire contents, including the packing oil, which will not match the preset for drained fillets. When in doubt, weigh the fish after draining and divide the label fat by that drained weight before multiplying by 100.
Frequently Asked Questions
Why does canned anchovy have more fat than raw?
Oil-packed fillets absorb some of the packing oil. Draining removes the free oil but absorption remains, which is why the per-100g fat figure is higher than raw fish.
What if I eat only one fillet?
Use the one-fillet quick-fill button (about 5 g) or enter the exact weight from your label. The calculator scales fat proportionally, so a 5 g fillet of drained oil-packed anchovy contributes roughly 0.49 g of fat.
Is anchovy fat considered healthy?
Anchovy fat is mostly unsaturated and supplies omega-3 fatty acids. This tool reports total fat only and does not separate saturated from unsaturated fat. For detailed nutrient profiles, see USDA FoodData Central; for label definitions, see the FDA Daily Value guidance.
