Calculate sodium in a homemade recipe and its portions

Build the ingredient total before dividing it

Write the amount used beside each ingredient’s label basis. Include stock, sauces, seasoning mixes and additions that went into the pot. For a label expressed per serving, multiply the sodium per serving by the number of those servings used. Keep milligrams throughout the calculation.

Do not replace an unknown ingredient with zero. If the stock amount is missing, the sum of the other ingredients is a partial total. A database substitute can be useful, but identify it as a substitute rather than presenting it as the actual label.

Measure the finished batch, not the empty container

If using weight, note the empty container weight first. Subtract that from the filled container weight to obtain the food’s finished weight. A weight-based division assumes the ingredients are distributed reasonably evenly; a portion with much more sauce or solids may differ.

For four genuinely equal portions, division by four is simpler. Do not divide by the recipe’s promised servings when you actually made a different yield.

Keep the estimate’s boundary with the result

If you drain liquid, discard part of a sauce or leave an ingredient behind, the original ingredient sum may no longer represent the food eaten. Do not invent a fixed percentage to subtract. Record the preparation and describe the result as an estimate.

Adding plain water changes the amount of soup, but does not remove sodium already in the retained ingredients. Keep the recipe total and the portion amount as separate fields so a thinner batch is not mistaken for a smaller total.

Save enough to repeat or revise the calculation

Keep a recipe name, version date, ingredient quantities, source of each number, finished yield and portion basis. Next time a brand or quantity changes, make a new version rather than silently editing old meals. Add toppings to the serving where they were eaten, not to every leftover portion.

This worksheet estimates intake; it does not set a sodium allowance. For an individual target or advice about uncertain ingredients, use your clinician’s or dietitian’s plan. The serving-size guide explains the single-food calculation behind each ingredient.

What if only half the recipe is retained?

If a uniform mixture is divided in half before any further changes, each retained half can be assigned half the estimated total. That assumption fails when you remove mostly liquid, pick out an ingredient or discard an uneven portion. Record which situation occurred. For leftovers, preserve the batch calculation and allocate the portion eaten later; do not add the entire original recipe to every day that includes a serving.

Use the free resources

The sodium resource page has related guides and tools. Use paper if that is easier; the article’s worksheet does not require an account or an app. Keep personal notes on your own device and share only the information needed for your question.
