Read the column heading and servings count together. Use the per-container total directly for that whole container, or scale the per-serving figures to your actual share, without multiplying twice.
Identify which container the label describes
Check whether the panel refers to the outer carton, one inner pot or an individually wrapped item. A multipack can place several layers of packaging around the food, so one pack is an ambiguous diary unit. Read the net amount, serving size and servings per container as a set. Keep the nutrition values attached to the same level of packaging.
The US FDA explains that labels can provide both per-serving and per-package information. Other label formats may instead provide per-serving and per-100-gram columns. Identify the actual heading rather than expecting the rightmost column to mean the whole pack everywhere. A container marketed for convenience is not necessarily one serving, and a stated serving is not a personal instruction about how much to eat.
Choose one route through a dual-column label
Consider an explicitly illustrative container listing three servings, 140 kcal per serving and 420 kcal per container. Eating the whole container means 420 kcal. You can obtain that directly from the container column or multiply 140 by three. Do not multiply 420 by three, because the whole-container figure already includes those servings. These are invented values for label arithmetic.
If you eat half the container, the corresponding estimate is 210 kcal, or one and a half labelled servings. Scale protein, carbohydrate and fat using the same chosen portion basis. If actual printed columns differ slightly after multiplication, check the quantities first and allow for possible rounding rather than changing your eaten share to make every displayed number match.
Handle shared containers and leftovers at the right level
A whole-container value applies to all its contents, not automatically the food on your plate. If you share the pack or save part, estimate your consumed fraction or use a matching weight. For a reasonably uniform product, a measured half has a clearer basis than a visual claim of almost all. Uneven products may require checking the component mix as well.
Keep a companion note identifying the container and remaining amount when that helps with the next meal. For example, outer carton has four pots; panel describes one pot is a useful packaging reference. Do not enter both one pot and one quarter of the carton if they describe the same food. Packaging hierarchy should clarify the calculation rather than create extra contributions.

Download Nexal for Android, create your account and try free manual meal and macro logging using a product with a clear container definition. Calculate the nutrition for your share outside the app and enter the resulting values. Keep the original packaging reference in your own notes if needed. This guide does not assume every label column is automatically interpreted by the app.
Before copying a recent meal, check whether the current pack has the same size and serving count. Premium barcode scanning is optional and does not establish how much of the container you ate. Finish by reading the record as a sentence: this product, this container reference, this consumed share. That check catches a whole-package figure accidentally treated as a single-serving figure before it becomes a recurring error.

Frequently asked questions
Should I multiply per-container calories by the serving count?
No. A per-container figure already describes that container. Multiply per-serving values by the number of servings eaten instead.
Does the outer carton count as one container?
Read the panel’s definition. A multipack may provide nutrition for an inner item rather than every item in the outer carton.
