Use this calculator to estimate the total calories in your homemade recipes and determine the calorie count per serving. Input each ingredient's quantity and its caloric value per 100 grams or milliliters.
Understanding Your Recipe's Caloric Content
Knowing the caloric content of your homemade recipes is a powerful tool for managing your diet, tracking macronutrients, and ensuring you meet your nutritional goals. This calculator simplifies the process by allowing you to input the raw ingredients and their respective caloric values.
How to Use the Calculator:
Add Ingredients: For each item in your recipe, enter its name (optional), the total quantity you are using (in grams or milliliters), and its caloric value per 100 grams or milliliters.
Find Caloric Values: You can typically find caloric values per 100g/ml on food packaging, online nutrition databases (like USDA FoodData Central), or by searching for "calories per 100g [ingredient name]".
Specify Servings: Enter the total number of servings your recipe yields.
Calculate: Click the "Calculate Recipe Calories" button to see the total calories for the entire recipe and per individual serving.
Important Considerations for Accuracy:
Raw vs. Cooked: Caloric values often refer to raw ingredients. Cooking methods can sometimes slightly alter nutrient density, but for most home cooking, using raw values is sufficiently accurate.
Water Content: Ingredients like vegetables lose water during cooking, which concentrates nutrients. However, the total calories remain the same unless fat or other caloric ingredients are added or removed.
Ingredient Specificity: Be as specific as possible. "Apple" calories differ from "apple sauce" calories. "Chicken breast" calories differ from "chicken thigh" calories.
Added Fats/Oils: Don't forget to include any cooking oils, butter, or other fats used in the recipe, as these are often calorie-dense.
Example Calculation:
Let's say you're making a simple pasta dish with the following ingredients:
Calories Per Serving: 1330 calories / 3 servings = 443.33 calories per serving
This calculator helps you quickly perform these calculations for any recipe you create!
var ingredientCounter = 1; // Start with 1 as the initial row is already there

}
function removeIngredientRow(buttonElement) {
var rowToRemove = buttonElement.parentNode;
rowToRemove.parentNode.removeChild(rowToRemove);
// No need to decrement ingredientCounter as IDs are not reused, just added.
// This simplifies things and avoids potential ID conflicts if rows are removed out of order.
