Nutrition Calculation Formula Explained
The calculator uses a simple but effective formula to estimate calories:
1. Calories Per Item Formula
Calories per item = Base Calories × Size Multiplier
Where:
- Base Calories = calorie value of selected sub
- Size Multiplier = portion adjustment factor
2. Total Calories Formula
Total Calories = Calories per item × Quantity
Where:
- Quantity = number of subs selected
Example Calculation
Let’s understand how the calculator works with a real example:
Scenario:
- Sub: Steak & Cheese (680 kcal)
- Size: Medium (1.5x)
- Quantity: 2
Step 1: Calculate per item calories
680 × 1.5 = 1020 kcal per sub
Step 2: Calculate total calories
1020 × 2 = 2040 kcal total
Final Result:
- Calories per item: 1020 kcal
- Total calories: 2040 kcal
This shows how quickly calories can increase with size and quantity adjustments.
