Tempeh is a fermented soybean cake that has become a staple of plant-based eating, prized for its nutty flavor, firm texture, and high protein content. But when you are tracking calories or macros, it is not always easy to know exactly how much energy is in your portion, especially since different tempeh styles and cooking methods change the numbers. This tempeh calories per 100g calculator removes the guesswork.
Enter your serving size in grams, choose a tempeh style or adjust the calories per 100 g from your package label, and the tool instantly calculates total calories plus a protein, carbohydrate, and fat breakdown. It works for plain soybean tempeh, five-grain tempeh, marinated versions, and fried preparations, making it useful for meal prep, weight management, and high-protein vegetarian diets.
Whether you are a home cook portioning dinner or a dietitian building client plans, this simple calculator turns a package label into a useful per-serving estimate.

How to Use This Calculator
This tool is designed for anyone tracking calories from tempeh without guessing. Start by entering how many grams of tempeh you actually ate — a typical serving is 100 g, but many recipes use 75 g or 150 g portions. Next, choose the tempeh style from the dropdown. Each style carries a different calorie density because of added oil, marinades, or grain blends. The calculator automatically fills the “Calories per 100 g” field with the selected style's average value, but you can override it if your package label gives a different number. This is especially useful for store-bought tempeh, where nutrition facts are authoritative. Finally, adjust the optional macronutrient fields if you want a protein, carbohydrate, and fat breakdown for your serving. Press Calculate Calories and the result appears instantly, including a per-serving macro summary based on your portion size. You can also tap a quick preset (50 g, 100 g, 150 g, 200 g) to fill the serving size automatically before calculating.
How the Math Works
The core calculation is a simple proportional conversion:
For example, if the label says 193 kcal per 100 g and you ate 85 g, the calculation is (193 ÷ 100) × 85 = 164 kcal. The same proportion applies to each macronutrient. Protein at 20.3 g per 100 g becomes (20.3 ÷ 100) × 85 = 17.3 g protein; carbs become (9.4 ÷ 100) × 85 = 8.0 g; fat becomes (10.8 ÷ 100) × 85 = 9.2 g. This linear scaling works because the nutrition panel is expressed per 100 g, and nutrient density is assumed to be evenly distributed through the food. It is the same method dietitians use when building meal plans from food labels.
Reference: Tempeh Nutrition Per 100 g
Values below are approximate and based on widely used nutrition databases and common commercial labels. Always defer to the brand-specific label when available.
| Tempeh style | Energy (kcal) | Protein (g) | Carbs (g) | Fat (g) |
|---|---|---|---|---|
| Plain soybean tempeh | 193 | 20.3 | 9.4 | 10.8 |
| Five-grain tempeh | ~179 | 16.5 | 16.0 | 7.0 |
| Marinated / flavored tempeh | ~220 | 15.0 | 12.0 | 12.0 |
| Fried / grilled with oil | ~270 | 17.0 | 13.0 | 17.0 |
Plain tempeh is notable for being a fermented whole-soy product with a generous protein-to-calorie ratio. It supplies more protein per 100 g than many other plant-based protein foods, which is why it is popular among vegetarians and athletes.
Real-World Applications
Accurate tempeh calorie counts matter for several practical scenarios. If you are following a weight-loss plan, a 200 g tempeh portion cooked with 2 tablespoons of oil can easily exceed 600 kcal, whereas the same amount of plain steamed tempeh is closer to 386 kcal. The calculator helps you separate these contributions. For high-protein plant-based diets, tempeh is a strong candidate because a 150 g serving delivers roughly 30 g protein for approximately 290 kcal. Also, if you track macros for muscle gain or balanced eating, the per-serving macro breakdown lets you log protein, carbs, and fat at the same time instead of looking up several database entries. Sports nutritionists often recommend tempeh as a fermented protein source that pairs well with rice or vegetables in post-workout meals.
Common Mistakes to Avoid
One common error is using the label value for raw tempeh while weighing a cooked portion. Frying or baking changes water content and may add oil, so calories per gram can increase noticeably. Another mistake is ignoring marinades: even a “plain” store-bought tempeh may contain added sugar, vinegar, or oil that shifts calories upward. Always check the ingredient list and nutrition panel for the exact product. A third issue is misreading portion sizes: packages are not always 100 g; a typical tempeh block in the United States is 227 g (8 oz), while some brands sell 250 g packs. If you eat half a 227 g block, your serving is 113.5 g, not 100 g. Weighing your food on a kitchen scale removes this guesswork.
Frequently Asked Questions
Is tempeh calorie-dense? No, plain tempeh is moderately calorie-dense: about 193 kcal per 100 g, similar to cooked quinoa but with much more protein. Frying adds a significant number of calories because oil contributes roughly 9 kcal per gram.
Can I eat tempeh on a low-carb diet? A 100 g serving of plain tempeh has about 9.4 g of total carbohydrates, around 3-4 g of which may be dietary fiber. This can fit into moderate low-carb or keto-style plans, especially when you account for net carbs: about 5-6 g per 100 g portion.
Why do different brands show different calorie counts? Tempeh recipes vary in soybean-to-grain ratio, added cultures, fermentation time, and enrobing ingredients. Some brands add vinegar or flavor mixtures, and five-grain tempeh replaces a portion of soybeans with wheat, barley, or millet, changing both carbohydrate and calorie values.
Does cooking change the calories? Cooking does not change the intrinsic calorie content of the tempeh itself, but weight changes from water loss and absorbed oil can alter calories per 100 g. That is why the calculator provides different style presets and an editable calorie field.
