Cola is famous for its sugar kick and caffeine buzz, but what about protein? If you are tracking macros, you probably suspect the answer already: cola has essentially zero protein. This Cola Protein Calculator turns that suspicion into exact numbers. Enter any serving size — a 12 fl oz can, a 20 fl oz bottle, a liter, or your own custom amount — choose your cola type, and you will see the protein content alongside calories, carbs, sugar, and caffeine.
Whether you are a bodybuilder logging protein grams, a dietitian double-checking a meal plan, or just a curious soda drinker, this calculator gives you a quick, reliable snapshot. It uses standard nutrition data for regular, diet, zero-sugar, and caffeine-free colas, so you can compare options side by side and see exactly what your soft drink is — and is not — contributing to your daily totals.

Step-by-step breakdown
The Short Answer: Does Cola Have Protein?
No. Standard reference data for regular, diet, and zero-sugar colas lists protein at 0 grams per 100 mL. That means a 355 mL can and a 2-liter bottle both contain essentially no protein — the tiny trace amounts that might appear on a lab test are nutritionally meaningless. Regular cola gets its calories almost entirely from added sugar or high-fructose corn syrup, while diet and zero-sugar versions get their sweetness from artificial or plant-based sweeteners. So if your goal is hitting a daily protein target, cola is a zero-protein beverage. It can still fit into a balanced diet, but it should never count toward protein intake.
How to Use This Calculator
- Enter a serving size in the number field. You can use decimals, such as 16.9 or 0.5.
- Choose the unit that matches your serving: fluid ounces, milliliters, cups, or liters.
- Pick the cola type: Regular Cola, Diet Cola, Zero Sugar Cola, or Caffeine-Free Regular.
- Click Calculate to see the protein, calories, carbs, sugar, and caffeine for that exact serving.
- Use Reset to clear the results and start a new comparison.
The quick-fill buttons below the serving field let you jump straight to common sizes: 12 fl oz can, 16.9 fl oz bottle, 20 fl oz bottle, and 1 liter. This makes it easy to compare a restaurant-sized bottle with a standard can.
How the Numbers Are Calculated
The calculator first converts your serving size to milliliters, then scales the per-100 mL values by the actual serving volume. For example, 12 fl oz equals roughly 355 mL, so the scale factor is 355 ÷ 100 = 3.55. Multiplying each per-100 mL value by 3.55 gives the totals for that can.
Since the protein value for every cola type in this tool is 0 g per 100 mL, the protein result will always be 0.0 g. The calorie, carb, sugar, and caffeine values scale linearly with serving size. Note that diet and zero-sugar colas have 0 g of carbs and 0 kcal, so their totals remain zero no matter how large the serving.
Worked Examples
Example 1: A 16.9 fl oz bottle of regular cola. A 16.9 fl oz bottle holds about 500 mL. The scale factor is 5. Using the regular cola values of 39 kcal, 11 g carbs, 11 g sugar, and 9.6 mg caffeine per 100 mL gives roughly 195 kcal, 55 g carbs, 55 g sugar, and 48 mg caffeine. Protein is 0 g.
Example 2: A 12 fl oz can of diet cola. At 355 mL, diet cola contributes 0 kcal, 0 g carbs, 0 g sugar, and 0 g protein. It does contain caffeine — around 46 mg in a standard can — so it is not caffeine-free even though it is calorie-free.
Example 3: Comparing regular and zero-sugar cola. A 20 fl oz regular cola contains roughly 230 kcal and 59 g sugar. The same size in zero-sugar cola contains 0 kcal and 0 g sugar, with a small amount of caffeine. This comparison helps explain why diet and zero-sugar options are popular for low-carb and calorie-controlled diets. For even finer serving comparisons, see the cola calories per tablespoon calculator.
Reference Values (Per 100 mL)
| Cola type | Calories | Protein | Carbs | Sugar | Caffeine |
|---|---|---|---|---|---|
| Regular cola | 39 kcal | 0 g | 11 g | 11 g | 9.6 mg |
| Diet cola | 0 kcal | 0 g | 0 g | 0 g | 13 mg |
| Zero-sugar cola | 0 kcal | 0 g | 0 g | 0 g | 9.6 mg |
| Caffeine-free regular | 39 kcal | 0 g | 11 g | 11 g | 0 mg |
These values reflect typical U.S. cola nutrition labels and USDA FoodData Central entries. Actual numbers vary slightly by brand, recipe, and regional sweetener type. If you follow a keto or low-carb diet, the drink net carbs calculator can help you assess the carbohydrate impact of other beverages too.
Frequently Asked Questions
Can I add protein powder to cola to make a protein drink? Yes, but be prepared for foam. Carbonated drinks react with protein powder and will fizz aggressively. Use a large glass, add the powder slowly, and stir gently rather than shaking. The final drink will contain the protein from the powder — usually 15 to 30 g per scoop — but none from the cola itself.
Is it true that cola has hidden protein? No. Some online lists mention protein from caramel color or other additives, but in nutrition labeling these do not contribute measurable macronutrient protein. The FDA allows a product to be labeled 0 g protein if it contains less than 0.5 g per serving.
Does cola count toward my daily protein needs? No. It should be recorded as calories, carbs, and sugar (or zero-calorie beverage) only. If you use a macro tracking app, enter cola under beverages and leave protein at zero.
