Yogurt is one of the most popular high-protein dairy foods — but its fat content varies enormously depending on whether you pick fat-free, low-fat, whole-milk, or Greek versions. A single 100 g serving can carry anywhere from 0.2 g to over 5 g of fat, which makes a real difference if you're tracking calories, following a keto or low-fat meal plan, or simply trying to make sense of food labels.
This calculator does the conversion work for you. Pick a common yogurt type to load its typical fat per 100 g, or enter the values straight from your brand's nutrition label. Then add your portion size in grams to see total fat in your bowl, calories from fat, and the share of your daily fat allowance — all in one step.
Use it to compare yogurts at the grocery store, adjust portion sizes for your diet goals, or double-check package claims. It is a handy companion for dietitians, students, and anyone who wants to eat yogurt with their eyes open.
🥛 Yogurt Fat Per 100g Calculator
Convert any yogurt label to a fat-per-100g standard and see exactly how much fat ends up in your bowl.
1. Choose a yogurt type
Typical average values from USDA FoodData Central.
2. Custom label values (optional override)
Have a specific brand? Enter the label numbers and the calculator will use them instead of the preset.
3. Your portion
How to Use This Tool
Start by selecting the yogurt type you're eating from the dropdown — the calculator loads a typical fat-per-100g value for each, based on USDA FoodData Central averages. If your product isn't listed, or the brand differs from the average, use the custom label fields instead. Enter the fat grams per serving and the serving size printed on the nutrition facts panel; the calculator will compute the exact fat per 100g for that specific product and use it for all downstream results.
Next, type in your portion weight in grams. No scale handy? Use the quick-fill buttons for common portions: 100 g, 150 g, 170 g, 200 g, or a standard 8 oz (227 g) container. Press Calculate and you'll get a full breakdown: fat per 100 g, total fat in your portion, calories from fat, and the percentage of the FDA's daily value for total fat (78 g on a 2,000-calorie diet).
Fat Content by Yogurt Type
The table below shows typical fat values per 100 g for common plain yogurts. Keep in mind that flavored versions add sugar and sometimes extra cream, which shifts both calories and fat.
| Yogurt type | Fat per 100 g | Calories per 100 g (approx.) |
|---|---|---|
| Non-fat plain yogurt | 0.2 g | ~41 kcal |
| Low-fat plain yogurt (1%) | 1.0 g | ~63 kcal |
| Low-fat plain yogurt (2%) | 2.0 g | ~74 kcal |
| Whole-milk plain yogurt | 3.3 g | ~79 kcal |
| Greek yogurt, non-fat | 0.4 g | ~59 kcal |
| Greek yogurt, 2% | 2.5 g | ~73 kcal |
| Greek yogurt, whole (5%) | 5.0 g | ~97 kcal |
| Skyr, non-fat | 0.3 g | ~55 kcal |
| Plant-based plain unsweetened | 3.0 g (varies widely) | ~55–80 kcal |
Values are typical averages from USDA FoodData Central; exact figures vary by brand and recipe.
The Math Behind It
The tool relies on one simple proportion. If a label says a 170 g serving contains 5 g of fat, the fat per 100 g is:
Example: (5 g ÷ 170 g) × 100 = 2.9 g per 100 g
Once you have the per-100g value, scaling to any portion is straightforward: multiply by your portion and divide by 100. Calories from fat use the standard Atwater factor of 9 kcal per gram of fat, and the daily-value percentage divides by the FDA's reference amount of 78 g of total fat per day for a 2,000-kcal diet. The official methodology is documented in the FDA's Nutrition Facts label guidance.
FDA: How to Understand and Use the Nutrition Facts Label
Reading the Numbers: Fat-Free, Low-Fat & Daily Value
In the US, nutrient-content claims such as "fat-free" and "low-fat" follow FDA definitions tied to the reference amount: fat-free products must contain less than 0.5 g of fat per serving, and low-fat products no more than 3 g per serving. Because this calculator works on a 100 g basis, it applies an approximate version of those cutoffs so you can compare honestly between brands and countries.

Tips & Common Mistakes
- Don't confuse serving size with container size. A single-serve pot can hold anywhere from 100 g to 200 g. Use the grams on the label, or weigh it once.
- Check whether the label's fat already includes added ingredients. Fruit-on-the-bottom or granola-topped yogurts have different fat and sugar numbers than plain yogurt.
- Be careful with cups. A measuring cup of yogurt weighs about 245 g, but a heaped spoon or dense Greek yogurt can weigh noticeably more. Gram weights are the only fair comparison.
- Compare products on a 100 g basis. That is exactly what this tool does — it lets you put a budget store brand next to a premium Greek yogurt and see which one truly has more fat.
- Remember fat is only one variable. Protein, calcium, and live cultures matter too. A slightly higher-fat yogurt can still be the better choice nutritionally.
Frequently Asked Questions
Is Greek yogurt higher in fat than regular yogurt?
Not necessarily. Greek yogurt is strained, which concentrates protein but also whatever fat the milk started with. Non-fat Greek yogurt has almost none, while whole-milk Greek yogurt is among the fattiest options at about 5 g per 100 g. Always read the specific variety.
Why do brands list the same fat per 100 g but different calories?
Calorie differences come mostly from carbohydrates (lactose and added sugar) and, in some cases, protein. Fat is only one contributor — 9 kcal per gram versus 4 kcal per gram for carbs and protein.
What is a reasonable daily fat target?
The FDA uses 78 g per day as the reference for a 2,000-calorie diet, which works out to about 30% of calories from fat. Individual targets vary with total calorie intake and health goals; a dietitian can help personalize yours.
How do I convert grams to ounces for yogurt?
Divide grams by 28.35. A 170 g portion is about 6 oz, and the 8 oz container used as a quick fill in this calculator is 227 g.
