Mathematical Formula & Logic

Salt (grams) = Sodium (mg) / 400 (Since table salt is roughly 40% sodium and 60% chloride)
Variable Glossary
Sodium (mg) Pure dietary sodium in milligrams
Salt (g) Equivalent weight in grams of Sodium Chloride (table salt)

Step-by-Step Worked Calculation

Scenario: Converting a 1,500 mg Low-Sodium Guideline to Salt

The American Heart Association recommends a limit of 1,500 mg of sodium for adults with hypertension.

1

Step 1: Set Sodium = 1,500 mg.

2

Step 2: Divide by 400 to find salt weight: 1,500 / 400 = 3.75 grams of salt.

3

Step 3: This translates to slightly less than 3/4 of a teaspoon of total salt per day.

How to Use the Sodium Intake Calculator

  1. 1. Enter your age and biological sex to calculate your **daily sodium recommendation**.
  2. 2. Select relevant health conditions (Hypertension, Kidney Disease, Heart Failure, or General Fitness) for the **sodium intake calculator**.
  3. 3. Review your target **daily sodium limit** in milligrams (mg) and **salt equivalent** in grams and teaspoons.
  4. 4. Use the **food comparison guide** to identify high-sodium processed foods and hidden salt sources.
  5. 5. Track your **sodium intake** across meals using the teaspoon equivalent for quick mental estimates.
  6. 6. Compare your targets against **DASH diet sodium** guidelines and **AHA recommendations**.
  7. 7. Save your **low sodium diet calculator** results for meal planning and grocery shopping.

What Is a Sodium Intake Calculator?

A Sodium Intake Calculator estimates the recommended maximum daily sodium (salt) consumption based on age, sex, and health conditions. It converts between milligrams of sodium and grams of table salt, and provides targets aligned with AHA, WHO, and DASH diet guidelines.

Why This Calculation Matters

Excessive sodium intake is a leading contributor to high blood pressure (hypertension), which increases the risk of heart disease, stroke, kidney disease, and fluid retention. Tracking daily sodium intake helps manage these conditions and maintain cardiovascular health.

Common Mistakes to Avoid

  • Confusing sodium with salt — table salt is only about 40% sodium; 1 teaspoon of salt contains approximately 2,300 mg of sodium
  • Ignoring hidden sodium in processed foods — bread, canned soups, sauces, and deli meats are major hidden sources
  • Thinking only about table salt — most dietary sodium comes from restaurant meals and packaged foods, not the salt shaker
  • Not adjusting sodium limits for health conditions — people with hypertension or kidney disease need stricter limits than the general population
