Wondering how many calories are in a single tablespoon of octopus? This calculator converts your portion into a quick calorie and macronutrient estimate using common nutrition values for octopus in different forms — raw, boiled/steamed, grilled, and canned in oil. Just enter the number of tablespoons and the calculator returns calories, protein, fat, and carbohydrates in one view.
This is especially handy for meal planners, seafood lovers, and anyone tracking macros. Because a tablespoon of chopped octopus can pack a different caloric punch depending on how it is cooked and whether oil is added, the tool lets you choose the preparation that matches your meal. An optional grams-per-tablespoon field gives you a more accurate result if you have weighed your portion.

🐙 Octopus Calories per Tablespoon
Choose a preparation, set your portion, then calculate calories and macros.
Step-by-Step Guide
This calculator is designed to work with tablespoons, a common volume measure in recipes, but octopus is often measured by weight in nutrition labels. Choosing the preparation that matches your meal is the most important step because cooking method and added oil change the calorie density. Here’s how to get a useful estimate:
- Enter the number of tablespoons of chopped octopus in the first field. If you are measuring a whole tentacle, chop it into small pieces so the tablespoon volume reflects what you eat.
- Select the preparation from the dropdown: raw/fresh, boiled/steamed, grilled/pan-seared without oil, or canned in oil and drained.
- Optional: if you have weighed your chopped octopus, enter the grams that fit in one tablespoon. The default of 15 g is a reasonable average, but water content can push it up or down.
- Click Calculate to see calories, protein, fat, and carbs, plus a step-by-step breakdown of the math.
How the Calculation Works
The tool uses nutrition values per 100 grams of edible octopus and converts them to your portion weight. The formulas are simple:
Total weight (g) = tablespoons × grams per tablespoon
Calories = total weight × kcal per 100g ÷ 100
Protein, fat, and carbs use the same pattern, replacing kcal per 100g with the corresponding value.
Example: 3 tablespoons of boiled octopus at 15 g per tablespoon gives 45 g total. At 82 kcal per 100g, calories = 45 × 82 ÷ 100 = 36.9 kcal. Protein = 45 × 14.9 ÷ 100 = 6.7 g; fat = 45 × 1.0 ÷ 100 = 0.5 g; carbs = 45 × 2.2 ÷ 100 = 1.0 g.
Nutrition Reference: Octopus by Preparation
Values are approximate edible portions, compiled from common seafood nutrition databases. Use them as a starting point for meal planning.
| Preparation | kcal / 100g | Protein / 100g | Fat / 100g | Carbs / 100g | Typical g / tbsp |
|---|---|---|---|---|---|
| Raw / fresh | 70 | 12.6 g | 1.0 g | 2.2 g | 15 g |
| Boiled / steamed | 82 | 14.9 g | 1.0 g | 2.2 g | 15 g |
| Grilled / pan-seared (no oil) | 82 | 14.9 g | 1.0 g | 2.2 g | 15 g |
| Canned in oil, drained | 150 | 15.0 g | 10.0 g | 1.0 g | 15 g |
Diced cooked octopus is roughly 15 g per tablespoon; raw pieces can be denser or looser depending on how tightly they are packed.
Tips & Best Practices
- Weigh when possible: a tablespoon is a volume measure, and cooked octopus can vary in moisture and chop size. One tablespoon of loosely packed pieces may weigh 12 g; tightly packed, 18 g.
- Watch added oil: searing in oil or buying canned octopus in oil can double the calorie count. If the can lists ingredients with oil as the second item, assume higher fat.
- Drain and pat dry: if using canned octopus, drain it well and pat dry with paper towels to remove excess oil before measuring.
- Cooked weight vs raw weight: values in this calculator refer to the octopus as eaten. If you start with raw, cooking removes water and concentrates protein, so use the cooked preparation option.
- Use it with other tools: for carbs-only tracking, see the octopus carbohydrate calculator, or for another seafood, the lobster calories per ounce calculator.
Frequently Asked Questions
Is octopus low in calories?
Yes. Plain cooked octopus is one of the leaner seafood options at about 82 calories per 100g. A tablespoon is only about 12 calories. However, preparations with oil, butter, or rich sauces raise the total quickly.
Why does canned octopus have so many more calories?
Canned octopus is usually packed in oil and may include marinades, which add fats. Even after draining, the absorbed oil remains. Choose octopus packed in water or brine if you want the leaner profile.
Can I use this calculator for keto or low-carb diets?
Yes. Boiled or grilled octopus has about 2.2g carbs per 100g, which is modest in ordinary portions. Canned in oil has slightly fewer carbs by weight, but the extra fat and calories may matter for your targets.
How accurate is the tablespoon measurement?
Volume measurements for chopped foods are inherently approximate. The default grams per tablespoon of 15g is an estimate; for medical or strict tracking, weigh the octopus and enter your measured grams per tablespoon into the optional field.
Limitations & Precision Notes
These figures are averages. The exact calories depend on the species, age, season, cooking duration, and added ingredients. Octopus can retain different amounts of water; boiling reduces weight but concentrates nutrients, so 100g of cooked octopus is not the same as 100g of raw octopus in the bowl.
The calculator also assumes standard 15 mL tablespoons and hand-chopped pieces without tightly packed gaps. Because of this, the tool is best for day-to-day tracking and meal planning rather than clinical nutrition calculations. For precise values, consult verified labels or search a food composition database such as USDA FoodData Central. For carb-specific data, pair it with the octopus carbs calculator.
