This Tempeh Calories Per Slice Calculator helps you quickly estimate the calories in a single slice of tempeh based on its weight, thickness, and preparation method. Whether you're meal prepping, tracking macros, or simply curious about the nutritional profile of this fermented soybean staple, this tool provides an accurate per-slice breakdown.
Tempeh is a nutrient-dense plant protein rich in fiber, vitamins, and minerals. By entering the total weight of your tempeh block and the number of slices you plan to cut, the calculator computes calories per slice, total calories, and macronutrient estimates (protein, carbs, fat). You can also adjust for cooking method (raw, steamed, pan-fried) to account for oil absorption or moisture loss. Perfect for vegans, vegetarians, and anyone following a balanced diet.
🧮 Tempeh Calories Per Slice
How to Use This Tool
Enter the total weight of your tempeh block (in grams or ounces) and the number of slices you plan to cut. Select the preparation method — raw/steamed or pan-fried — to account for oil absorption. Click "Calculate" to see calories and macronutrients per slice and for the whole block. Use the reset button to clear results and start over. For best accuracy, weigh your tempeh block on a kitchen scale before slicing. If you are using a standard store-bought block (typically 200 g or 8 oz), you can use the default values as a quick starting point.
How It Works
The calculator uses standard nutritional data for tempeh: approximately 193 kcal, 20 g protein, 9 g carbohydrates, and 11 g fat per 100 g of raw tempeh. For pan-fried tempeh, we estimate an additional 37 kcal per 100 g from oil absorption, adjusting macros accordingly. The formula is: Calories per slice = (weight in g / 100) × cal per 100 g / number of slices. All values are rounded to one decimal place. The macronutrient breakdown is based on USDA data for raw tempeh (soybeans, fermented). For pan-fried tempeh, we assume about 1 teaspoon of oil (5 g) per 100 g of tempeh, which adds roughly 37 kcal and 4 g of fat, while slightly reducing the relative protein and carb percentages due to the added oil weight.
Worked Examples
Example 1: A 200 g block of raw tempeh cut into 8 slices. Weight per slice = 25 g. Calories per slice = (200/100) × 193 / 8 = 48.3 kcal. Protein per slice = (200/100) × 20 / 8 = 5.0 g. Carbs = 2.3 g, Fat = 2.8 g. Total block: 386 kcal, 40 g protein, 18 g carbs, 22 g fat.
Example 2: A 150 g block pan-fried, cut into 6 slices. Calories per slice = (150/100) × 230 / 6 = 57.5 kcal. Protein = 4.5 g, Carbs = 2.0 g, Fat = 4.0 g. Total block: 345 kcal, 27 g protein, 12 g carbs, 24 g fat.
Example 3: A 250 g block of raw tempeh cut into 10 slices. Weight per slice = 25 g. Calories per slice = (250/100) × 193 / 10 = 48.3 kcal. Protein per slice = 5.0 g, Carbs = 2.3 g, Fat = 2.8 g. Total block: 482.5 kcal, 50 g protein, 22.5 g carbs, 27.5 g fat.
Tips for Accuracy
Weigh your tempeh block on a kitchen scale for the most accurate results. Slice thickness affects weight per slice — use a consistent number of slices. For pan-frying, the actual oil absorption varies; our estimate assumes about 1 teaspoon of oil per 100 g tempeh. For steamed tempeh, use the raw setting as steaming adds negligible calories. If you marinate your tempeh, note that marinades (e.g., soy sauce, vinegar, oil) can add significant calories — consider calculating those separately. For the most precise tracking, weigh the cooked tempeh after frying, as moisture loss can concentrate calories slightly.
Frequently Asked Questions
Is tempeh high in calories? Tempeh is moderately calorie-dense compared to vegetables but lower than many meats. A typical slice (25 g raw) has about 48 kcal, making it a great protein source for weight management. Compared to chicken breast (about 165 kcal per 100 g), tempeh is slightly higher in calories but also higher in fiber and beneficial phytonutrients.
Can I use this for marinated tempeh? Marinades add calories (e.g., soy sauce, oil). This calculator does not account for marinades — for best results, calculate marinade separately. A typical marinade of 2 tbsp soy sauce (20 kcal) and 1 tbsp oil (120 kcal) per 200 g block would add about 140 kcal total, or 17.5 kcal per slice if cut into 8 slices.
How does tempeh compare to tofu? Tempeh is generally higher in protein and fiber than tofu. Per 100 g, tofu has about 76 kcal and 8 g protein, while tempeh has 193 kcal and 20 g protein. For a tofu calorie tool, see our Tofu Nutrition Calculator.
Where can I find more tempeh nutrition data? The USDA FoodData Central provides comprehensive nutritional profiles for tempeh and other foods. Visit fdc.nal.usda.gov for detailed information. You can also check the tempeh manufacturer's website for specific brand data, as some commercial tempeh may include added grains (like brown rice or barley) that alter the nutritional profile slightly.
