Formula Used
Label ingredient sodium: Ingredient sodium = Amount × sodium per unit × retention percent ÷ 100.
Total recipe sodium: Total sodium = label sodium + chemical sodium + absorbed brine sodium.
Sodium per serving: Sodium per serving = total sodium ÷ number of servings.
Salt equivalent: Salt equivalent grams = total sodium mg ÷ 393.4.
Table salt conversion: Sodium from salt = salt grams × 393.4 mg.
Baking soda conversion: Sodium from baking soda = baking soda grams × 273.7 mg.
MSG conversion: Sodium from MSG = MSG grams × 122.8 mg.
Sodium citrate conversion: Sodium from sodium citrate dihydrate = grams × 234.5 mg.
Brine sodium: Brine sodium = volume ml × density × salt percent ÷ 100 × absorbed percent ÷ 100 × 393.4.
How to Use This Calculator
Enter a recipe name and serving count. Add a sodium limit if you want a comparison.
Fill ingredient rows using package labels. Put the recipe amount in the amount box.
Enter the sodium value for one matching unit. For example, use sodium per cup when the amount is in cups.
Use retention percent when sodium is drained or partly discarded. Use 100 percent when all sodium remains.
Add grams of salt, baking soda, MSG, or sodium citrate if your recipe uses them.
For brines, enter the liquid volume, salt percent, density, and absorbed percent.
Press Calculate Sodium. The result appears below the header and above the form.

About Sodium in Recipes
Why Sodium Math Matters
Sodium changes flavor, texture, and nutrition. It is not the same as table salt. Table salt is sodium chloride. Only part of its weight is sodium. That is why recipe math can be confusing.
What This Tool Measures
This calculator separates label sodium from chemical sodium sources. You can enter packaged ingredients by serving, gram, milliliter, teaspoon, or any unit you choose. Then you can add salt, baking soda, monosodium glutamate, sodium citrate, and brine absorption. The result shows total sodium and sodium per serving.
Serving Size Changes Everything
A recipe can look moderate in the whole pot but high on the plate. Serving count matters. A soup with eight portions may fit a daily goal. The same pot served in four bowls may exceed it. This tool keeps both views visible.
Chemistry Behind the Conversion
Food labels report sodium in milligrams. Recipe writers often use teaspoons or grams. Chemistry helps bridge that gap. Sodium chloride contains about 39.34 percent sodium by mass. Baking soda contains about 27.37 percent sodium. Monosodium glutamate contains less sodium than salt by weight, but it still adds sodium.
Retention and Brines
Retention also matters. Pickles, marinades, and salted cooking water do not always stay fully in the food. The retention field lets you estimate how much sodium remains after draining, rinsing, baking, or serving. Use 100 percent when everything is eaten.
Planning Better Recipes
This calculator is useful for meal prep, clinical diet planning, food blogging, and product development. It can compare a planned recipe with a chosen sodium limit. It can also show how much sodium must be removed per serving. You may reduce salt, use unsalted broth, rinse canned foods, or increase servings.
Accuracy Notes
The result is still an estimate. Label rounding, brand changes, and measuring methods can shift the final number. For strict medical diets, confirm numbers with official labels and professional advice. For everyday cooking, the calculator gives a clear starting point. It makes sodium decisions easier before ingredients reach the pan.
For best accuracy, weigh salty ingredients whenever possible. Volume spoons can vary. Coarse salt has larger crystals and less weight per spoon. Fine salt packs more tightly. When you know the gram amount, use the gram fields. Keep saved CSV files with your tested batches. Update values whenever labels or serving sizes change. Test again before publishing.
FAQs
Is sodium the same as salt?
No. Salt is sodium chloride. Sodium is only part of salt by weight. This calculator converts salt grams into sodium milligrams using the sodium share in sodium chloride.
How do I use package label sodium?
Match the amount and unit. If the label says 400 mg per cup and you use 3 cups, enter amount 3 and sodium per unit 400.
What does retention percent mean?
Retention percent estimates how much sodium stays in the final food. Use 100 percent when everything remains. Use a lower value when liquid is drained or discarded.
Can I calculate sodium from baking soda?
Yes. Enter the baking soda weight in grams. The calculator uses sodium bicarbonate chemistry to estimate sodium from that amount.
Does MSG add less sodium than salt?
By weight, MSG has less sodium than table salt. It still contributes sodium, so include it when a recipe needs careful sodium control.
How should I handle brines?
Enter brine volume, density, salt percent, and absorbed percent. The tool estimates the salt absorbed, then converts that absorbed salt into sodium.
Why is my sodium per serving high?
Common causes include salty broth, canned foods, sauces, seasoning blends, baking soda, and small serving counts. Increasing portions or reducing salty ingredients lowers each serving.
Is this suitable for medical diets?
It can support planning, but it is an estimate. People following strict medical limits should verify label data and ask a qualified health professional.
