Anchovies are small but remarkably protein-dense fish, delivering about 20 grams of protein per 100 grams in fresh form and more when canned, salted, or dried. This calculator estimates the exact protein in any portion measured in grams, ounces, fillets, or cans, and also shows calories from protein plus how the serving contributes to a typical 50-gram daily protein target.
Built for meal planners, athletes tracking macros, and high-protein dieters, the tool includes four anchovy forms with different protein densities. Results update with one click, so portion math takes seconds. No food scale? Use the fillet or can presets to estimate from common serving sizes.
🐟 Anchovy Protein Calculator
Protein in anchovies, however you measure them.
How to Use This Tool
Using the calculator takes just a few steps. First, choose the unit that matches how you are measuring your anchovies: grams, ounces, fillets, or cans. If you are weighing a fresh portion from the fishmonger, grams or ounces make sense. If you are building a sandwich, salad, or pasta dish from a tin, the fillet and can options give an instant estimate without a food scale.
Second, select the form of anchovy that matches what you actually have — raw fresh fillets, canned in oil and drained, cured or salted, or dried. Protein density changes a lot between these forms, so this choice drives most of the result. Third, press Calculate protein. The result panel shows total protein, the calories supplied by that protein, and how the serving compares with a 50 g daily target. The preset pills above the button give quick estimates for 50 g, 100 g, 1 oz, one fillet, and one drained can.
How It Works
The calculator uses standard USDA food-composition values for protein density per 100 g of edible flesh: raw or fresh anchovy has 20.35 g, canned in oil and drained has 29.13 g, cured or salted has 24.8 g, and dried has 47.5 g. These figures refer to the edible portion, not the whole fish including head, tail, and large bones.
The calculation happens in two steps. First, your portion is converted to grams: 1 ounce equals 28.3495 g, one fillet is treated as 5 g, and one drained can as 45 g. Then protein is found with the formula:
Protein (g) = portion in grams × (protein per 100 g ÷ 100)
So a 100 g portion of canned anchovies is 100 × 0.2913 = 29.1 g of protein. Calories from protein use the Atwater factor of 4 kcal per gram, and the daily-value percentage is the protein divided by a 50 g reference target for a typical adult diet.
Worked Examples
Example 1 — One drained can. At 45 g drained and the canned density of 29.13 g per 100 g: 45 × 0.2913 = 13.1 g protein, about 52 kcal from protein, and 26% of a 50 g target.
Example 2 — Two fillets in a salad. Two 5 g fillets equal 10 g. Using the same canned density: 10 × 0.2913 = 2.9 g protein. Small on its own, but cheese, egg, and dressing in a Caesar salad add protein too.
Example 3 — A 3 oz fresh portion. 3 oz converts to 85.0 g, so 85.0 × 0.2035 = 17.3 g protein and about 69 kcal from protein. Paired with a grain bowl, this easily covers a third of a 50 g daily target.
Reference Table
| Form | Protein / 100 g | Calories from protein | Typical serving | Protein per serving |
|---|---|---|---|---|
| Raw / fresh | 20.4 g | 81 kcal | 100 g | 20.4 g |
| Canned in oil, drained | 29.1 g | 117 kcal | 45 g can | 13.1 g |
| Cured / salted | 24.8 g | 99 kcal | 50 g | 12.4 g |
| Dried | 47.5 g | 190 kcal | 30 g | 14.3 g |
Common Mistakes to Avoid
- Weighing the whole can contents. Oil and brine add weight but almost no protein. Drain canned anchovies before weighing, or use the 45 g drained-can default.
- Confusing salted with dried. Salted fillets still hold water; dried anchovies have been dehydrated, so their protein per 100 g is roughly double.
- Assuming every fillet is 5 g. That figure suits typical Mediterranean fillets, but larger premium fillets can reach 8–10 g, adding 60–100% more protein.
- Ignoring sodium. Cured and canned anchovies are extremely salty — roughly 3,600–7,000 mg per 100 g — which matters for anyone managing blood pressure, even when the protein numbers look appealing.
Frequently Asked Questions
Are anchovies a good high-protein food?
Yes. A 100 g portion of drained canned anchovies delivers about 29 g of protein for roughly 210 kcal, making them one of the most protein-efficient fish options. They also provide omega-3 fats, calcium from soft bones, and vitamin D.
Why is dried anchovy protein so much higher?
Drying removes water, concentrating protein into a smaller weight. Per 100 g, dried anchovies contain about twice the protein of raw fish.
How many fillets are in a typical can?
A standard 45 g drained can generally holds 8–12 fillets depending on size, which matches the 5 g per fillet estimate used here.
Is 50 g the right daily protein target for everyone?
It is a convenient general benchmark. Actual needs vary: guidelines suggest about 0.8 g per kg of body weight for sedentary adults and 1.2–2.0 g per kg for active people. Focus on the protein grams shown and adjust the percentage in your head if your target differs.
