This calculator helps you determine the protein content per 100g of any milk type — from whole cow's milk to almond, soy, oat, and goat milk. Whether you're tracking macronutrients for muscle building, managing a high-protein diet, or comparing plant-based alternatives, knowing the exact protein per 100g is essential for accurate meal planning.
Simply select your milk type, adjust the fat percentage if applicable, and optionally enter a serving size to see total protein. The tool also provides a breakdown of calories and other key nutrients per 100g, making it a versatile companion for nutrition tracking, diet planning, and healthy eating.
🥛 Milk Protein Per 100g
How to Use This Tool
Select your milk type from the dropdown — options include cow's milk at various fat levels, goat, sheep, buffalo, and popular plant-based milks like soy, almond, oat, rice, and coconut. Enter the serving size in grams (default is 100g). Click Calculate to see the protein content per 100g and for your specific serving, along with calories, fat, and carbohydrates. Use the Reset button to clear results and start over.
How It Works
The calculator uses standard USDA and manufacturer nutrition data for each milk type. Protein values are expressed in grams per 100g of milk. The formula is simple: Protein (g) = (Protein per 100g × Serving Size in g) / 100. The same calculation applies to calories, fat, and carbs. For example, whole cow's milk contains approximately 3.3g protein per 100g. If you drink a 250g glass, you get (3.3 × 250) / 100 = 8.25g of protein.
Worked Examples
Tips & Best Practices
- For accurate tracking, weigh your milk in grams using a kitchen scale rather than relying on volume measurements (1 cup of milk is approximately 244g, but density varies).
- If you're using flavored or sweetened plant-based milks, the protein content may be slightly lower due to added sugars and other ingredients. Check the label.
- For high-protein diets, cow's milk (all fat levels), soy milk, and sheep milk are excellent choices. Almond and rice milk are very low in protein.
- Use this tool alongside other nutrition calculators like Broccoli Protein Calculator or Cottage Cheese Protein Calculator to plan balanced meals.
Factors Affecting Accuracy
Protein content can vary due to: breed of cow (Jersey vs. Holstein), season, feed, and processing methods. For plant-based milks, fortification with pea protein or other additives can increase protein levels. The values here represent typical averages from major databases. For clinical or medical purposes, consult a registered dietitian.
Frequently Asked Questions
Q: Which milk has the most protein per 100g?
A: Sheep milk leads with 5.4g per 100g, followed by buffalo milk (3.8g) and goat milk (3.6g). Among plant-based options, soy milk (3.3g) is the highest.
Q: Does fat content affect protein in cow's milk?
A: No — whole, 2%, 1%, and skim cow's milk all contain essentially the same amount of protein (3.3–3.4g per 100g). The fat is removed without affecting protein.
Q: Is this tool suitable for lactose intolerance?
A: Yes — you can select lactose-free cow's milk (similar protein to regular) or plant-based options. Note that oat and rice milks are naturally lactose-free but low in protein.
Q: Can I use this for cooking and baking?
A: Absolutely. Knowing the protein per 100g helps adjust recipes for higher or lower protein content. For example, substituting whole milk with soy milk in a smoothie boosts protein without adding animal products.
