Pork is a surprisingly rich source of potassium, a vital mineral that supports heart health, muscle contraction, and fluid balance. Whether you’re tracking your daily intake for athletic performance, managing blood pressure, or simply curious about your nutrition, this calculator gives you a quick and accurate estimate of the potassium in your pork serving.
Designed for home cooks, dietitians, fitness enthusiasts, and anyone following a potassium-conscious diet, this tool lets you select the cut of pork and enter your serving size in grams or ounces. It instantly calculates the potassium content in milligrams and shows how that compares to the recommended daily value of 4,700 mg.
Simply choose your cut, enter the amount you plan to eat, and hit Calculate. You’ll get a clear breakdown, including potassium per 100 grams, so you can compare cuts and plan meals with confidence.

How to Use This Tool
Using the Pork Potassium Calculator is straightforward. Start by selecting the cut of pork you're planning to eat from the dropdown menu. Each cut has a different potassium density, so this choice matters. Next, enter the amount you'll consume in either grams or ounces — the calculator automatically converts ounces to grams using the standard factor of 1 oz = 28.3495 g. If you're unsure about portion sizes, the quick-fill buttons (3 oz, 4 oz, 100g, 150g) provide common serving references. After clicking Calculate, you'll see the total potassium in milligrams, the potassium per 100 grams for that cut, and the percentage of the recommended daily value (4,700 mg for adults).
For the most accurate results, weigh your pork before cooking, as moisture loss during cooking can slightly concentrate minerals. However, the potassium content per 100 grams of cooked meat is generally similar to raw values when adjusted for water loss, so this calculator works well for both raw and cooked portions.
Potassium in Pork: The Basics
Potassium is an essential electrolyte that helps regulate nerve signals, muscle contractions, and fluid balance. It also works with sodium to maintain healthy blood pressure. The average adult needs about 4,700 mg per day, but many people fall short. Pork is a valuable source — a typical 3-ounce serving of pork loin provides roughly 300–400 mg, which is about 7–9% of the daily requirement.
Different cuts vary in potassium content due to fat and connective tissue. Leaner cuts like tenderloin tend to have slightly more potassium per 100 grams than fattier cuts like belly, because potassium is concentrated in muscle tissue. The table below shows approximate values for common cuts:
| Cut of Pork | Potassium (mg per 100g) |
|---|---|
| Pork Loin | 350 |
| Pork Chop | 300 |
| Pork Tenderloin | 400 |
| Ground Pork | 300 |
| Pork Belly | 200 |
| Ham (cured) | 300 |
These values are based on USDA FoodData Central and represent cooked, lean portions. Cured products like ham may have added sodium, which can affect potassium balance, so check labels if you're on a sodium-restricted diet.
How the Calculation Works
The calculator uses a simple proportional formula. First, your serving size is converted to grams if needed. Then, the potassium content is calculated as:
Potassium (mg) = (Serving Size in grams ÷ 100) × Potassium per 100g for that cut
For example, if you eat 150 grams of pork tenderloin (which has 400 mg per 100g), the calculation is (150 ÷ 100) × 400 = 600 mg. The daily value percentage is then computed by dividing this number by 4,700 mg and multiplying by 100.
This method assumes that potassium is evenly distributed throughout the meat, which is a reasonable approximation for practical purposes. Cooking method (grilling, roasting, frying) does not significantly alter the mineral content per gram of cooked meat, though water loss can concentrate nutrients slightly.
Worked Examples
Let's walk through a few scenarios to illustrate how the calculator can be used:
Example 1: You're having a 4-ounce pork chop for dinner. Convert 4 oz to grams: 4 × 28.3495 = 113.4 g. Pork chop has 300 mg per 100g, so potassium = (113.4 ÷ 100) × 300 = 340 mg. That's about 7.2% of your daily value.
Example 2: You're meal-prepping with 200g of ground pork. Ground pork has 300 mg per 100g, so potassium = (200 ÷ 100) × 300 = 600 mg — a solid contribution to your daily target.
Example 3: A small serving of pork belly (85g) provides (85 ÷ 100) × 200 = 170 mg, which is less than 4% of the daily value. This shows how cut selection impacts your potassium intake.
These examples highlight that leaner cuts like tenderloin offer more potassium per gram, making them a better choice if you're aiming to boost your intake.
Tips for Managing Potassium Intake
If you're tracking potassium for health reasons, here are some practical tips:
- Pair pork with potassium-rich sides: Serve with sweet potatoes, spinach, or beans to increase your total intake.
- Rinse cured meats: If using ham or bacon, rinsing can remove some surface sodium, but it won't affect potassium much.
- Watch portion sizes: A typical restaurant pork chop can be 8–12 ounces, which may push your potassium intake higher than expected.
- Balance with other electrolytes: Potassium works with sodium and magnesium, so a varied diet is key.
- Consult a professional: If you have kidney disease or take medications that affect potassium, always follow your doctor's or dietitian's guidance.
Remember that this calculator provides estimates, not medical advice. For precise dietary planning, use a comprehensive nutrition database or consult a registered dietitian.
Frequently Asked Questions
Q: Does cooking method change the potassium content?
A: Not significantly. Potassium is a mineral that doesn't break down with heat. However, if you discard cooking juices, you may lose some water-soluble minerals, but the effect on potassium in the meat itself is minimal.
Q: Is pork a good source of potassium compared to other meats?
A: Yes, pork is comparable to chicken and beef. For example, chicken breast has about 350 mg per 100g, similar to pork loin. Pork tenderloin is actually one of the higher-potassium meats.
Q: Can I use this calculator for raw or cooked pork?
A: Both work, but be consistent. Raw pork has more water, so 100g raw will yield less cooked meat. If you weigh after cooking, use that weight for the most accurate potassium estimate.
Q: What if I eat a different cut not listed?
A: The values are approximate. For other cuts, you can use the closest match or look up the specific value in the USDA FoodData Central database. The calculator's formula is easy to replicate manually.
If you're also tracking potassium in other foods, you might find our egg potassium calculator useful for breakfast planning, or our caesar potassium calculator for salad-based meals. These tools use the same methodology, making it easy to compare across foods.
