Total recipe calories - typically found by summing each ingredient's individual calorie contribution - only becomes a meaningful per-serving figure once divided by how many actual servings the finished dish makes.
Worked example
For a recipe totaling 2,400 calories, cut into 8 servings:
Per Serving = 2400 / 8 = 300.0 kcal per serving
Be consistent about how servings are actually portioned in practice - cutting a recipe into more or fewer pieces than originally planned directly changes the real calories per serving, even though the total recipe calories haven't changed at all.
