Chicken thighs are a favorite for good reason — they're juicy, affordable, and packed with protein. But they also carry more fat than chicken breast, especially when the skin stays on, so calories add up quickly. This thigh nutrition calculator estimates calories, protein, and fat in chicken thighs based on how many you're eating, each thigh's weight, whether the skin is on, and your cooking method.
Enter the number of thighs, pick a size preset or type your own weight, choose skin-on or skinless, and select a preparation style. The calculator works in grams or ounces and returns a full macro breakdown for the whole serving and per thigh — ideal for meal prep, macro counting, and quick dinner math.
All figures are based on standard USDA nutrition reference values, so treat the results as a practical planning estimate. Actual numbers vary with bird size, moisture loss, and any added oil or marinade.

How to Use This Tool
Start by entering how many thighs you plan to serve. The default assumes one medium thigh, but you can adjust the number up or down for meal-prep batches. Next, set the weight per thigh using the quick presets (small, medium, large) or type your own value in grams or ounces. Finally, choose whether the skin is on and how the thighs will be cooked — raw, baked, grilled, or pan-fried — then press Calculate Nutrition.
- Enter the number of thighs (whole number, 1 or more).
- Choose a weight preset or enter a custom per-thigh weight in grams or ounces.
- Select skin-on or skinless and your cooking method.
- Review the total calories, protein, fat, per-thigh calories, and calorie split. Use Copy Summary to save the result to your clipboard.
The Math Behind It
This calculator uses published USDA nutrient values per 100 grams of edible chicken thigh meat. For each preparation style, three reference values are stored: kilocalories, protein grams, and fat grams per 100 g. The total cooked weight of your serving is calculated by multiplying the per-thigh weight by the number of thighs, then each nutrient is scaled proportionally. The same scaling works in ounces because the calculator converts ounces to grams automatically before applying the reference values.
Calories = (kcal per 100 g) x total weight / 100
Protein = (protein g per 100 g) x total weight / 100
Fat = (fat g per 100 g) x total weight / 100
Protein and fat calorie contributions are computed using 4 kcal per gram of protein and 9 kcal per gram of fat; the remaining calories are attributed to carbohydrate (negligible in plain chicken) and rounding. This is the same style of math used in most nutrition tracking apps.
Worked Examples
Here are two common scenarios you can try in the calculator with your own numbers.
Example 1 — Baked skin-on thighs for four. Four thighs at 110 g each, skin-on, roasted in the oven. Total weight = 440 g. Using baked skin-on values (229 kcal, 24.4 g protein, 14.5 g fat per 100 g): calories come to about 1,008 kcal, protein about 107 g, fat about 64 g, or roughly 252 kcal per thigh.
Example 2 — Skinless meal prep. Five skinless thighs at 120 g each, grilled. Total weight = 600 g. Grilled skinless values (151 kcal, 24.7 g protein, 5.3 g fat per 100 g) give roughly 906 kcal, 148 g protein, and 32 g fat — about 181 kcal per thigh with a much leaner fat profile.
Standard Reference Values
The table below shows the per-100 g nutrient values used by the calculator. These approximate USDA data for chicken thigh, meat and skin versus skinless, across common preparations.
| Preparation | Skin | Calories (kcal) | Protein (g) | Fat (g) |
|---|---|---|---|---|
| Raw | Skin on | 184 | 18.6 | 11.8 |
| Raw | Skinless | 120 | 20.5 | 4.1 |
| Baked / Roasted | Skin on | 229 | 24.4 | 14.5 |
| Baked / Roasted | Skinless | 155 | 24.6 | 5.7 |
| Grilled / Broiled | Skin on | 208 | 24.4 | 11.9 |
| Grilled / Broiled | Skinless | 151 | 24.7 | 5.3 |
| Pan-fried | Skin on | 264 | 25.1 | 17.7 |
| Pan-fried | Skinless | 187 | 25.4 | 8.8 |

Factors That Affect Accuracy
Your results are only as good as your inputs. Marinating in oil, finishing with butter, dredging in flour, or using a sauce can add 50–200 kcal or more per serving. Weigh thighs after cooking if possible, since moisture loss during roasting or grilling concentrates nutrients per gram.
Any packaged, restaurant, or grocery-store nutrition panel can differ from the USDA averages used here. Thigh size also varies widely — a large skin-on thigh can weigh 150 g or more, while a trimmed skinless thigh may weigh 80 g. Individual birds, breeds, feed, and cooking temperature all cause natural variation. For the most accurate tracking, weigh your actual portion and use the numbers as a close planning estimate rather than an exact chemical analysis.
Frequently Asked Questions
Why is skin-on thigh so much higher in calories? The skin is mostly fat, roughly 80% fat by weight after cooking. Removing it typically cuts about 40–80 kcal per 100 g depending on the cooking method, while protein stays nearly the same.
Should I weigh my thigh raw or cooked? Weigh cooked, because water loss during cooking increases nutrient density per gram. A 110 g raw thigh may finish around 80–90 g cooked; if you enter raw weight but choose a cooked method, the calculator slightly overestimates the nutrients you actually ate.
Can I use this for chicken breast or drumsticks? The values here are specific to thighs. Chicken breast is considerably leaner, and drumsticks sit between the two. Check USDA FoodData Central for breast or drumstick equivalents.
