Sodium intake calculator

Track sodium from meals, snacks, and packaged foods against a daily target. Enter milligrams per serving and serving counts to see your total sodium, remaining allowance, percentage of target, and salt equivalent.

Best uses

  • •Quickly total sodium from nutrition labels across a full day of meals.
  • •Compare a lower 1,500 mg target with the general 2,300 mg daily limit.
  • •Spot the highest sodium source so you know which item to swap first.

How sodium is calculated

For each food, the calculator multiplies sodium per serving by the number of servings, then totals every row. Salt equivalent is estimated using the common conversion of sodium × 2.542.

Frequently Asked Questions

What is the usual daily sodium limit?

Many general guidelines use 2,300 mg sodium per day as an upper limit. Some people are advised to aim closer to 1,500 mg, especially when following a lower-sodium diet. Always follow personal medical advice if you have it.

Is sodium the same as salt?

No. Sodium is one component of salt. This calculator estimates salt equivalent by multiplying sodium by 2.542, then converting milligrams to grams.

Where do I find sodium per serving?

Look at the nutrition label and use the sodium value listed per serving. If you eat more than one serving, enter that number in the servings field.

Can I use this for meal prep?

Yes. Add each ingredient or prepared item as a row, then divide the sodium per recipe by the number of portions if you want a per-meal estimate.

Is this medical advice?

No. It is a planning and label-reading tool. If you have high blood pressure, kidney disease, heart disease, or a prescribed sodium target, use the target from your clinician.

Pro Tips

  • • Restaurant meals and deli meats often contribute more sodium than snacks, so start there when reducing intake.
  • • If a label lists salt instead of sodium, sodium is roughly salt grams ÷ 2.542 × 1,000.
  • • Use the highest sodium source card to identify the easiest swap.
