Octopus is a lean, protein-rich seafood that is naturally low in saturated fat, but its cholesterol content can vary significantly depending on the cooking method and portion size. This calculator helps you estimate the cholesterol, total fat, and calories in octopus based on the amount and preparation style you choose.
Whether you are tracking your daily cholesterol intake for heart health, following a low-cholesterol diet, or simply curious about the nutritional profile of this popular cephalopod, this tool provides quick, reliable estimates. Use it to compare raw, boiled, grilled, or fried octopus and make informed meal decisions.

How to Use This Tool
Enter the amount of octopus you plan to eat (in grams or ounces), select the preparation method (raw, boiled, grilled, or fried), and click "Calculate." The tool instantly estimates the cholesterol, total fat, and calorie content based on standard USDA nutritional data for octopus. Use the quick-fill buttons to load common serving sizes and preparations with one click. The results display all three values side by side, with a breakdown note explaining the basis of the estimate.
Tip: For the most accurate results, weigh your octopus before cooking. Cooking methods that add oil (like frying) will increase both fat and calorie content significantly. If you use a different cooking oil or add butter, the fat and calorie estimates will be higher than shown.
How It Works
The calculator uses the USDA National Nutrient Database values for raw octopus: approximately 48 mg cholesterol, 1.04 g fat, and 82 kcal per 100 grams. For cooked preparations, we apply adjustment factors based on typical moisture loss and oil absorption:
- Raw: 1.0× (baseline, no adjustment)
- Boiled: 1.1× (slight concentration due to water loss during boiling)
- Grilled: 1.15× (more moisture loss from direct heat)
- Fried: 1.3× (moisture loss plus oil absorption, typical for shallow or deep frying)
These factors are estimates based on published food science research; actual values depend on cooking time, temperature, and the amount of oil used. The cholesterol content itself is relatively stable during cooking, but the concentration effect from moisture loss can increase the cholesterol per gram of cooked octopus.
Example Calculations
Example 1: 100 g raw octopus → 48 mg cholesterol, 1.04 g fat, 82 kcal.
Example 2: 150 g grilled octopus → First, apply the grilled factor: 150 × 1.15 = 172.5 g equivalent. Then calculate: cholesterol = (48 × 172.5) / 100 = 82.8 mg; fat = (1.04 × 172.5) / 100 = 1.79 g; calories = (82 × 172.5) / 100 = 141 kcal.
Example 3: 85 g (3 oz) fried octopus → Apply the fried factor: 85 × 1.3 = 110.5 g equivalent. Then: cholesterol = (48 × 110.5) / 100 = 53.0 mg; fat = (1.04 × 110.5) / 100 = 1.15 g; calories = (82 × 110.5) / 100 = 91 kcal.
Example 4: 200 g boiled octopus → Apply the boiled factor: 200 × 1.1 = 220 g equivalent. Then: cholesterol = (48 × 220) / 100 = 105.6 mg; fat = (1.04 × 220) / 100 = 2.29 g; calories = (82 × 220) / 100 = 180 kcal.
Factors Affecting Accuracy
The cholesterol content of octopus can vary by species, age, and diet. The USDA values used here are averages for common octopus species (e.g., Octopus vulgaris). Cooking methods that involve added fats (butter, oil) will increase the fat and calorie content beyond our estimates. Additionally, if you consume octopus with high-cholesterol sauces or sides, the total meal cholesterol will be higher. The moisture content of the octopus can also vary depending on freshness and storage conditions, which may affect the concentration of nutrients after cooking.
Frequently Asked Questions
Is octopus high in cholesterol? Octopus contains about 48 mg of cholesterol per 100 g, which is moderate — similar to chicken breast but lower than shrimp (about 150 mg per 100 g) or eggs (about 370 mg per 100 g). However, it is very low in saturated fat (about 0.3 g per 100 g), which is a key factor for heart health. The American Heart Association emphasizes limiting saturated fat rather than dietary cholesterol for most people.
Can I eat octopus on a low-cholesterol diet? Yes, in moderation. The American Heart Association recommends limiting dietary cholesterol to 200–300 mg per day for those with high cholesterol or heart disease risk. A 100 g serving of octopus provides about 16–24% of that limit, and its low saturated fat content makes it a heart-friendly choice. Pair it with vegetables and whole grains for a balanced meal.
Does cooking method affect cholesterol? The cholesterol molecule itself is relatively stable, but cooking can concentrate or dilute it due to moisture changes. Frying adds fat and calories but does not chemically alter cholesterol significantly. Grilling and boiling may cause some loss of fat-soluble nutrients, but cholesterol remains largely unchanged.
Where can I find more detailed nutrition data? The USDA FoodData Central database provides comprehensive nutritional profiles for octopus and thousands of other foods. Visit fdc.nal.usda.gov for the latest data. You can also consult the American Heart Association for dietary guidelines on cholesterol and heart health.
