Peanuts are a beloved snack and a staple in many diets, but their sodium content can vary dramatically depending on how they are prepared. Raw or dry-roasted peanuts are naturally very low in sodium, while salted, honey-roasted, or flavored varieties can pack a surprising amount of salt into a small handful. This calculator helps you estimate the sodium in your peanut serving based on the type, amount, and preparation method.
Whether you are tracking your daily sodium intake for heart health, managing blood pressure, or simply curious about your snack habits, this tool gives you a quick and accurate estimate. Simply choose the peanut type, enter the amount you plan to eat (in grams, ounces, or cups), and optionally adjust for added salt. The calculator will break down the sodium per serving and per 100 grams, helping you make informed choices.
Use it for meal planning, diet tracking, or just to satisfy your curiosity. It is designed for anyone—from health-conscious snackers to dietitians—who wants a clearer picture of what is really in their peanut bowl.

How to Use This Tool
Using the peanut sodium calculator is straightforward. Start by selecting the type of peanut you are eating from the dropdown—options include raw, dry-roasted unsalted, dry-roasted salted, oil-roasted salted, honey-roasted, and boiled. Next, enter the amount you plan to consume. You can specify the quantity in grams, ounces, or cups, and the calculator will automatically convert to grams for the sodium calculation. If you add extra salt to your peanuts, you can optionally enter that amount in grams or teaspoons to get a more accurate total. Click the Calculate Sodium button to see your results, which include the total sodium per serving, per 100 grams, and per 1-ounce (28 g) portion. The breakdown section shows how much sodium comes from the peanuts themselves versus any added salt.
How It Works
The calculator uses standard USDA FoodData Central values for sodium content per 100 grams of each peanut type. For example, raw peanuts contain about 18 mg of sodium per 100 g, while dry-roasted salted peanuts contain around 410 mg per 100 g. Boiled peanuts are notably higher, at about 751 mg per 100 g, because they absorb salt from the cooking water. When you enter an amount, the calculator converts it to grams using these conversions: 1 ounce = 28.3495 g, and 1 cup of peanuts = 146 g (based on average density). The base sodium is then calculated proportionally. If you add salt, the calculator estimates the sodium contribution by assuming table salt is about 40% sodium by weight. One teaspoon of salt weighs approximately 6 grams, so it contributes roughly 2,400 mg of sodium.
Worked Examples
Example 1: You eat a 1-ounce (28 g) serving of dry-roasted salted peanuts. The calculator converts 28 g to grams (already in grams), then multiplies 410 mg/100 g × 28 g / 100 = 114.8 mg. So your serving contains about 115 mg of sodium.
Example 2: You have a cup of boiled peanuts (146 g). The sodium per 100 g is 751 mg, so 751 × 146 / 100 = 1,096 mg. That's over half of the recommended daily limit of 2,300 mg.
Example 3: You snack on 50 g of raw peanuts and add 0.5 teaspoon of salt. Base sodium = 18 × 50 / 100 = 9 mg. Added salt = 0.5 tsp × 6 g/tsp × 0.4 × 1000 = 1,200 mg. Total = 1,209 mg.
Tips & Best Practices
- Always check the nutrition label on packaged peanuts—sodium content can vary by brand and flavoring.
- If you are watching your sodium for blood pressure or heart health, choose unsalted or lightly salted varieties.
- Portion control matters: a small handful (about 1 ounce) is a reasonable serving, but it's easy to eat more.
- When adding salt, remember that even a quarter teaspoon adds about 600 mg of sodium.
- Use the per-100g figure to compare different peanut products on an equal basis.
Factors Affecting Accuracy
The sodium values used are averages from the USDA and can vary by brand, recipe, and preparation method. For example, some salted peanuts may have more or less salt depending on the manufacturer. Boiled peanuts can vary widely based on how much salt is in the cooking water and how long they soak. If you have the nutrition label, you can enter the exact sodium per 100 g (if available) to refine your estimate. The added salt calculation assumes standard table salt; sea salt and kosher salt have different densities and sodium percentages, so adjust accordingly if you use those.
Frequently Asked Questions
Are peanuts high in sodium?
It depends on the type. Raw and unsalted peanuts are very low in sodium (under 20 mg per 100 g), while salted varieties can contain 400 mg or more per 100 g. Boiled peanuts are the highest, often exceeding 700 mg per 100 g.
How much sodium should I have per day?
The American Heart Association recommends limiting sodium to 2,300 mg per day, with an ideal limit of 1,500 mg for most adults, especially those with high blood pressure.
Can I use this calculator for other nuts?
No, this calculator is specific to peanuts. Other nuts have different sodium profiles, especially if salted. You can use the same principles with their nutrition data.
Why do boiled peanuts have so much sodium?
Boiled peanuts are cooked in salted water, and they absorb a significant amount of salt during the cooking process. The longer they soak, the saltier they become.
