Not all fat is the same. The Green Fat Calculator helps you estimate the amount of healthy, mostly unsaturated fat in a serving of common green plant foods — from creamy avocado and brined green olives to edamame, pistachios, hemp seeds, and pumpkin seeds. If you are meal-prepping, following a Mediterranean-style diet, or simply trying to hit a daily fat target, this tool turns a serving size into a clear fat profile.
Just choose a food, enter the amount in grams or ounces, and select your daily fat target. The calculator returns total fat, calories from fat, saturated fat, monounsaturated fat, polyunsaturated fat, and the percentage of your daily fat target covered by that serving. Use the quick-fill buttons for common serving sizes, then compare foods to plan snacks, salads, and sides with confidence.

How to Use This Tool
This calculator is designed for anyone tracking fat intake from plant-focused foods. Start by selecting a food from the dropdown, then enter your serving size in grams or ounces. If you are working from a recipe, the quick-fill buttons help you jump to common amounts such as 100 g or 1 oz. Next, choose a daily fat target that matches your eating pattern — the standard 78 g figure is based on a 2,000-calorie diet and the 10%–35% acceptable macronutrient distribution range for fat.
Press Calculate to see your results. The main number is total fat in grams, followed by calories from fat and the percentage of your daily target that this serving covers. The breakdown then shows saturated, monounsaturated, and polyunsaturated fats, so you can see how much of the fat is the heart-friendly unsaturated kind. Use the Reset button to clear the form and start again.
Note: Values are based on raw, unsalted foods unless stated otherwise. Prepared foods with added oil, butter, or dressing will have more fat than the number shown here.
How It Works
The calculator uses reference nutrition data per 100 grams for each food. That per-100g value is scaled to your serving using this formula:
Fat in serving = fat per 100 g × (serving weight in g ÷ 100)
Once total fat is known, calories from fat are calculated at 9 kcal per gram of fat, and the daily value percentage is computed by dividing total fat grams by your chosen target. The same scaling is applied to saturated, monounsaturated, and polyunsaturated fats so you can see the complete fatty-acid profile of the serving.
Example: For 120 g of edamame, with 5.20 g fat per 100 g, total fat = 5.20 × 1.20 = 6.24 g. Calories from fat = 6.24 × 9 = 56 kcal. Against a 78 g target, that serving supplies about 8% of the daily fat target.
Worked Examples
Example 1 — Avocado toast. You use 75 g of avocado on toast. Avocado contains about 14.66 g fat per 100 g, so 75 g supplies 11.0 g fat. Of that, roughly 7.4 g is monounsaturated and only 1.6 g is saturated. This shows why avocados are a rich source of the same type of monounsaturated fat found in olive oil.
Example 2 — Pistachio snack. A 40 g handful of pistachios contains about 18.3 g fat. The monounsaturated plus polyunsaturated share is roughly 15.3 g, with about 2.2 g saturated. That snack would supply about 23% of a 78 g daily fat target before you account for anything else you eat that day.
Tip: If you are comparing two foods, set the serving size to 100 g on both and press Calculate. This gives you a clean per-100g comparison, which is the standard way nutrition labels are written.
Standard Values
The table below shows the fat values used by this calculator, in grams per 100 g of food. These reference values are useful for quick mental estimates when you do not have the calculator open.
| Food | Total fat | Saturated | Monounsaturated | Polyunsaturated |
|---|---|---|---|---|
| Avocado | 14.7 g | 2.1 g | 9.8 g | 1.8 g |
| Green olives | 15.3 g | 2.0 g | 11.3 g | 1.3 g |
| Edamame (cooked) | 5.2 g | 0.6 g | 1.0 g | 2.2 g |
| Pistachios | 45.8 g | 5.6 g | 23.8 g | 14.4 g |
| Hemp seeds | 48.8 g | 4.3 g | 5.4 g | 38.1 g |
| Pumpkin seeds | 49.1 g | 8.7 g | 16.3 g | 20.8 g |
Tips & Best Practices
- Weigh before cooking. For edamame, use shelled beans and weigh them after cooking but before adding any seasoning or oil. The nutrition data here refers to cooked green soybeans without salt.
- Watch the serving unit. Ounces are converted to grams automatically, but remember that 1 fluid ounce of oil is not the same as 1 ounce by weight. This calculator works with weight ounces.
- Don't ignore saturated fat. Even healthy green foods contain some saturated fat. Pumpkin seeds, for example, have about 8.7 g saturated fat per 100 g. The breakdown helps you keep that in perspective.
- Combine with other macronutrients. Fat is only one piece of the picture. For calorie or protein planning, pair this tool with other nutrition calculators to see the full serving profile.
- Adjust the target to your plan. A 2,000-calorie diet with 30% of calories from fat uses a 67 g target; the 78 g default is closer to 35% of calories. Choose the target that matches your diet plan.
Be careful with added fats. The numbers for olives and seeds are for the plain foods. If you buy marinated olives, roasted nuts with oil, or seasoned edamame, check the package label because the fat per serving can be noticeably higher.
Frequently Asked Questions
What exactly is a “green fat”?
“Green fat” is not an official nutrition term. In this calculator, it refers to healthy plant-derived fats found in green foods such as avocado, green olives, edamame, and certain nuts and seeds. These foods are valued for their unsaturated fat content, which can support heart health when used in place of saturated fats.
Are avocados the best source of green fat?
Avocados are a convenient source of monounsaturated fat and add creamy texture, but they are not necessarily “best.” Hemp seeds and pumpkin seeds have much more total fat per 100 g, while edamame offers a lighter option with more protein relative to fat. The best choice depends on your calorie needs and how you plan to use the food.
Can I use this calculator for dairy fats too?
This tool focuses on plant foods. If you want to estimate the fat content of a latte or other dairy-based drink, the latte fat calculator is a better fit. That calculator handles the fat in milk-based coffee drinks, which have a very different fatty-acid profile from plant foods.
Why do the unsaturated numbers not add up to the total fat?
Total fat includes saturated, monounsaturated, and polyunsaturated fats, but it also includes small amounts of other lipid components such as phytosterols and free fatty acids. Because of rounding and these minor components, the three categories may not sum exactly to the total fat value shown.
Where do the reference values come from?
The values are based on standard USDA FoodData Central entries for each food. USDA data is widely used in nutrition calculators because it is publicly available and based on laboratory analysis. For commercial packaged products, always use the nutrition facts panel on the package, because recipes and processing methods vary.
