Calculator Inputs
The page uses a single-column flow, while the calculator fields switch to three columns on large screens, two on medium screens, and one on mobile.
Example Data Table
| Food | Sodium/Serving (mg) | Servings | Serving Size (g) | Total Sodium (mg) |
|---|---|---|---|---|
| Chicken wrap | 540 | 1 | 260 | 540 |
| Soup cup | 460 | 1 | 240 | 460 |
| Crackers | 180 | 1.5 | 30 | 270 |
| Fruit | 5 | 1 | 120 | 5 |
| Total | - | - | 650 | 1,275 |
Formula Used
1) Food sodium contribution
Food Sodium = Sodium per Serving × Servings Eaten
2) Total meal sodium
Total Meal Sodium = Sum of all Food Sodium contributions
3) Even split meal budget
Even Budget = Daily Sodium Target ÷ (Meals per Day + Snacks per Day)
4) Custom meal budget
Custom Budget = Daily Sodium Target × Meal Allocation % ÷ 100
5) Sodium density
Sodium Density = Total Meal Sodium ÷ Meal Weight × 100
6) Daily share
% of Daily Target = Total Meal Sodium ÷ Daily Sodium Target × 100
7) Sodium per 100 calories
Sodium per 100 Calories = Total Meal Sodium ÷ Planned Meal Calories × 100
How to Use This Calculator
- Enter your daily sodium target and the number of meals and snacks you usually eat.
- Set the meal allocation percentage for the meal you want to evaluate.
- Add planned calories and a manual meal weight if you want density-based analysis.
- List each food item with sodium per serving, servings eaten, and serving size.
- Press the calculate button to show the result above the form.
- Review total sodium, budget comparisons, density, and top contributors.
- Use the CSV or PDF buttons to export the calculated summary and breakdown tables.
FAQs
1) What does sodium per meal mean?
It is the total sodium you consume in one eating occasion. The calculator adds sodium from each listed food, then compares that amount with your daily goal and meal budget.
2) Why compare against both custom and even budgets?
An even budget assumes sodium is split evenly across all eating occasions. A custom budget lets breakfast, lunch, dinner, or snacks receive different shares based on your routine.
3) What is sodium density?
Sodium density shows how much sodium is packed into 100 grams of food. It helps compare lighter and heavier meals more fairly, especially when portion size changes.
4) Why is meal weight optional?
If you provide serving sizes, the tool estimates meal weight automatically. A manual weight lets you override that estimate when you know the plated meal weight more accurately.
5) What does sodium per 100 calories show?
It measures sodium relative to energy intake. This helps identify meals that deliver a lot of sodium without many calories, which can matter when planning nutrient-dense meals.
6) Can I use label values from packaged foods?
Yes. Enter the sodium listed per serving on the label, then add the number of servings you actually ate. This usually gives a practical meal estimate.
7) Does this replace professional nutrition advice?
No. It is a planning tool. People with hypertension, kidney disease, heart failure, or prescribed diets should confirm limits and meal strategies with a qualified clinician or dietitian.
8) What should I do if the meal is over budget?
Look at the top contributor first. Swapping sauces, breads, soups, cured meats, or packaged sides often reduces sodium quickly without changing the full meal plan.
