Recipe Scaling Nutrition Calculator

Doubling a recipe or taking it from 4 servings to 40 changes more than the ingredient list — it can change the nutrition per serving too. Add your recipe below and scale it to any batch size with recalculated, FDA-rounded nutrition facts.

Why Manually Scaling Nutrition Facts Goes Wrong

The instinct when scaling a recipe is to just multiply: 4 servings becomes 40, so multiply every nutrient by 10 and call it done. That works for the batch total. It does not reliably work for the per-serving numbers that actually go on your label.

Linear division ignores yield changes

A soup simmered for 4 servings and the same soup simmered for 40 servings don't necessarily lose water at the same rate. If your finished yield doesn't scale exactly proportionally to your ingredient weight, dividing the old per-serving number by a batch multiplier gives you a number that no longer matches what's actually in each container.

Rounding compounds across servings

Round each ingredient's contribution first, then scale, and small rounding errors stack up as the batch grows. A 0.3g error per serving at 4 servings is nothing. The same rounding mistake applied across 400 servings can shift your total protein or sodium enough to matter.

Serving size assumptions don't scale

Scaling a recipe up often means re-portioning into different container sizes. If your serving size changes from "1 cup" to "1 container" without re-verifying the weight, your nutrition facts panel can describe a serving that doesn't match what you're actually packaging.

How NutriLabelPro Recalculates Instead of Multiplying

Recalculates from ingredients, not old totals

When you scale a recipe, we recompute nutrition from your actual scaled ingredient quantities rather than multiplying a previously rounded total.

Rounds once, at the end

FDA rounding rules are applied to the final per-serving number only, so errors never compound across a large batch.

Any batch size, any serving count

Save a recipe once and re-scale it from 4 servings to 400 whenever your order size changes, without redoing the math by hand.

Allergens scale with the recipe

Allergen detection runs against your full ingredient list every time you scale, so nothing gets dropped when quantities change.

Did you know? The FDA allows calories to round to the nearest 5 below 50 calories, and the nearest 10 at or above 50 (49 cal → 50 cal). We apply this automatically after every rescale. Learn FDA rounding rules →

Frequently Asked Questions

Can I just multiply the nutrition facts when I scale a recipe?

Only for the total batch, not per serving — and even then it is risky. Multiplying total calories by 10 to go from 4 servings to 40 works fine for the batch total, but per-serving numbers depend on how you re-divide the batch, how much moisture or volume was lost during cooking, and how rounding compounds across servings.

Why does scaling a recipe change the nutrition per serving?

Cooking method interacts with batch size. Larger batches often cook longer, which changes water evaporation, fat rendering, and final yield weight — so dividing by the same serving count as before can give the wrong per-serving numbers.

Does rounding error get worse when I scale a recipe up?

Yes, if you round at the wrong step. The correct approach is to calculate exact nutrition for the full scaled batch first, divide by the actual number of servings, and apply FDA rounding rules only at the very end.

What is the FDA rounding rule I should apply after scaling?

Calories round to the nearest 5 below 50 and the nearest 10 at or above 50. Fat, carbohydrate, and protein round to the nearest 0.5g under 1g and the nearest 1g at or above 1g. % Daily Value always rounds to a whole number.

Do I need to create a new label every time I change my batch size?

If the batch size change affects the per-serving nutrition numbers by a meaningful amount, yes. NutriLabelPro lets you save a recipe once and re-scale it to any batch size on demand.
