Cod is one of the leanest white fish in the seafood aisle, and its natural carbohydrate count is essentially zero — usually 0 g per 100 g whether you eat it raw, baked, broiled, or poached. That makes it a favorite for low-carb, keto, diabetic, and clean-eating meal plans. But the picture changes the moment cod is battered, breaded, or pre-marinated, because those coatings introduce flour, starch, and sugar.
This calculator estimates how many carbs actually end up in your portion. Start by entering your serving weight in grams or ounces, choose the preparation method that matches your meal, or enter the exact carb value from a food label using the custom value option. You’ll instantly see total carbs, net carbs, fiber, sugar, and calories-from-carbs for the portion you’re about to cook or eat.
Use it for meal prep, macro tracking, or simply to answer how many carbs are in cod before you plan your next dinner.
Cod Carbs Per 100g Calculator
Estimate total and net carbs in any portion of cod based on preparation.
Quick Start
This calculator is built for anyone who tracks carbohydrate intake: keto and low-carb dieters, people managing diabetes, fitness enthusiasts, and meal-prep cooks. Start by entering your portion weight in grams or ounces, then choose the preparation method that matches your meal. The preset values cover plain raw, baked, broiled, poached, steamed, and dried cod, as well as common breaded and battered options.
If the cod you are eating has a nutrition label, tick the "I have a label carb value" box and type the exact carbs per 100 g from the package. This overrides the preset values and is the most accurate option for branded products, frozen meals, or restaurant items with published nutrition data.
Formula Explained
All calculations use a simple proportion. If a food has a nutrient value per 100 g, the amount in any portion is:
Portion nutrient (g) = (portion weight ÷ 100) × nutrient value per 100 g
For example, if your cod portion weighs 170 g and has 8.1 g carbs per 100 g for breaded fish, the total carbs are 170 ÷ 100 = 1.70, then 1.70 × 8.1 = 13.8 g. Net carbs are computed by subtracting fiber from total carbs. Because plain cod contains almost no fiber, net and total carbs are virtually identical for raw, baked, poached, and dried cod. Breaded and battered cod add a small amount of fiber from wheat flour, so net carbs are only slightly lower than total carbs in those cases.
Calories from carbs are calculated at 4 kcal per gram of carbohydrate. When you use a preset preparation, total calories are scaled from USDA reference values for that preparation. When you enter a custom label value, the calculator estimates calories from carbs, protein, and fat using the standard 4-4-9 energy factors.
Reference Data per 100 g
Preset values are based on USDA FoodData Central entries for Atlantic cod and common coated fish preparations. Branded products can differ, so treat these as reasonable estimates and use label data when you have it.
| Preparation | Carbs (g) | Sugar (g) | Fiber (g) | Protein (g) | Calories |
|---|---|---|---|---|---|
| Raw / fresh | 0.0 | 0.0 | 0.0 | 17.8 | 82 |
| Baked / broiled | 0.0 | 0.0 | 0.0 | 22.7 | 105 |
| Poached / steamed | 0.0 | 0.0 | 0.0 | 20.4 | 90 |
| Dried / salted | 0.0 | 0.0 | 0.0 | 62.8 | 290 |
| Breaded & fried | 8.1 | 0.3 | 0.3 | 18.0 | 201 |
| Battered & fried | 10.6 | 0.5 | 0.4 | 18.3 | 232 |

Worked Examples
Example 1: Raw cod fillet
You weigh a 170 g raw fillet. Raw cod has 0 g carbs per 100 g. Factor = 170 ÷ 100 = 1.70. Total carbs = 0 × 1.70 = 0 g. Net carbs = 0 g. This makes plain cod a zero-carb protein option.
Example 2: Breaded fish fillet
A 150 g breaded, fried cod fillet uses the preset 8.1 g carbs per 100 g. Factor = 150 ÷ 100 = 1.50. Total carbs = 8.1 × 1.50 = 12.2 g. Fiber = 0.3 × 1.50 = 0.5 g. Net carbs = 12.2 − 0.5 = 11.7 g.
Example 3: Custom label value
Your frozen cod dinner label says 12.5 g carbs per 100 g and you plan to eat the whole 250 g package. Tick the custom checkbox, enter 12.5, and enter 250 g. Factor = 250 ÷ 100 = 2.50. Total carbs = 12.5 × 2.50 = 31.3 g. Since fiber is not reported on the label, net carbs are treated as 31.3 g.
Tips & Best Practices
- Weigh cod after cooking for the most accurate portion-level macros, because cooking removes water and makes each gram more nutrient-dense. If you are logging a recipe that lists raw weights, use the raw preparation option.
- Plain frozen cod, even with added water or ice glaze, normally has 0 g carbs per 100 g. Check the ingredient list for added sugar, modified starch, or seasoning blends, which can add carbs.
- Homemade breaded fish can vary widely. A lighter coating of almond flour or pork rinds will produce far fewer carbs than a traditional flour-and-breadcrumb coating.
- If you are following a net-carb counting method, subtract fiber from total carbs. The difference is meaningful only for coated cod, and even then it is small.
- Restaurant fish and chips are almost always battered, not breaded. Battered cod tends to have more carbs and calories per 100 g than a dry breadcrumb coating.
Frequently Asked Questions
Is cod keto-friendly?
Yes. Plain cod has 0 g carbs per 100 g and is very low in fat, so it fits comfortably into keto, low-carb, and diabetic meal plans. Be careful with coated fish, which can add 8–11 g of carbs per 100 g.
Does cod contain any natural sugar?
Plain cod contains no measurable sugar. Small amounts of sugar appear only when marinades, glazes, or breading ingredients are added.
Why do nutrition labels for battered cod differ?
The carb count depends on the thickness of the batter, the flour used, added starch, sugar in the batter, and the cooking oil absorbed during frying. Always prefer the label of the exact product over a general estimate.
How many carbs are in a typical cod fillet?
A typical 170 g raw fillet contains 0 g carbs. The same fillet with a standard breadcrumb coating contains roughly 14 g total carbs, and with a thicker beer batter it can reach 18 g or more.
