Shrimp is one of the leanest and most protein-dense seafood options available, making it a favourite among athletes, fitness enthusiasts, and anyone tracking macros. A 100-gram serving of cooked shrimp typically delivers around 20 grams of protein with very little fat or carbohydrate, but the exact number depends on how the shrimp is prepared. This shrimp protein per 100g calculator converts any serving size to its protein equivalent, whether you weigh your food in grams, ounces, or pounds.
Simply enter your amount, choose your unit, and pick a preparation method — raw, boiled, grilled, canned, or fried — and the tool instantly shows total protein, protein per 100g, daily value percentage, and an estimated shrimp count based on average size. You can even override the protein density if you have a label from a specific package. This makes it easy to log meals accurately in your calorie tracker or plan high-protein dishes.
⚙️ Step-by-step
Quick Start: Reading Your Result
Enter the exact amount of shrimp you plan to eat — 85 g, 4 oz, or even half a pound — and select the unit. Choose a preparation method from the dropdown so the calculator uses the right protein density. If the package label gives a different value, type it into “Protein per 100g (override)” and it will take priority. Click Calculate Protein to see your serving’s total protein, per-100g protein, daily value percentage, and an approximate shrimp count.
For day-level planning, pair this with the nutrition target calculator to see how a shrimp meal fits your total protein goal.
The Math Behind the Shrimp Protein Calculator
The calculator uses a simple proportion: protein = serving weight in grams × (protein per 100 g ÷ 100). First the serving amount is converted to grams. Then the chosen preparation’s protein density, in grams of protein per 100 grams of shrimp, is multiplied across the actual serving weight. The result appears in grams of protein.
If you choose raw shrimp, the calculator uses approximately 18.4 g protein per 100 g. Boiled or steamed shrimp is about 20.4 g per 100 g because moisture loss concentrates protein. Grilled shrimp lands near 20.6 g per 100 g. Canned shrimp is lower at 17.6 g per 100 g because packing liquid returns some water. These values reflect typical USDA FoodData Central entries, but individual shrimp from different regions and brands may vary by 1–2 grams.
Reference: Protein in Common Shrimp Preparations
The table below lists typical protein values used in this tool. Use them when comparing shrimp to other protein sources or logging food in a nutrition app.
| Preparation | Protein per 100 g | Calories per 100 g (approx.) |
|---|---|---|
| Raw / uncooked | 18.4 g | 85 kcal |
| Boiled / steamed | 20.4 g | 99 kcal |
| Grilled / baked | 20.6 g | 99 kcal |
| Canned | 17.6 g | 87 kcal |
| Fried / breaded | 18.8 g | 130 kcal |
The calorie values are close estimates, since breading, oil, and seasoning change numbers. Protein values come from typical USDA data for plain shrimp; always prefer a specific label when available.
Worked Examples
Example 1 — Raw shrimp in grams. You weigh 125 g raw shrimp. Raw protein density is 18.4 g per 100 g. Protein = 125 × 18.4 ÷ 100 = 23.0 g. This is about 46% of a 50 g daily value.
Example 2 — Cooked shrimp in ounces. You eat a 4 oz portion of boiled shrimp. Convert 4 oz to grams: 4 × 28.3495 = 113.4 g. Boiled protein density is 20.4 g per 100 g. Protein = 113.4 × 20.4 ÷ 100 = 23.1 g.
Example 3 — One-pound raw shrimp. A 1 lb raw shrimp serving is 453.6 g. Protein = 453.6 × 18.4 ÷ 100 = 83.5 g, which would account for a large portion of a strength athlete’s daily target. Because shrimp is low in fat and carbs, this protein comes with only about 385 kcal before any butter, oil, or sauce is added.
Factors That Affect Shrimp Protein Content
- Water content: Fresh shrimp naturally holds a lot of water; cooking removes moisture and can raise protein density per gram by about 10%.
- Species and size: White shrimp, pink shrimp, tiger shrimp, and rock shrimp differ slightly in macronutrients.
- Processing: Saltwater injection, brining, and phosphate treatments increase water weight, lowering protein as a percentage of total weight.
- Breading and batter: Coating adds carbohydrate and oil, which lowers protein percentage relative to total food weight.
- Liquid loss during thawing: Frozen shrimp can lose water when thawed; weigh after draining for better accuracy.
Frequently Asked Questions
Do I weigh shrimp raw or cooked? Weigh cooked shrimp for the food you actually eat. If a recipe or meal plan lists raw weights, use the raw option in this calculator. Swapping between raw and cooked weights without adjusting the preparation will over- or underestimate protein by a few grams.
Is shrimp a complete protein? Yes. Shrimp provides all nine essential amino acids, making it a high-quality complete protein, although it is lower in some amino acids than chicken or beef. Its protein quality is excellent for building muscle and supporting satiety.
How much shrimp is a typical serving? A moderate portion is 85–113 g (3–4 oz) cooked. This calculator’s 100 g base makes it easy: 100 g cooked shrimp delivers roughly 20 g protein, so most servings are around 17–23 g protein.
Does shrimp have carbs or fat? Plain shrimp has about 0–1 g carbohydrate and less than 1 g fat per 100 g, making it ideal for low-carb, ketogenic, and high-protein diets. Breaded or fried preparations change this dramatically.
