Ham is a popular and versatile protein, but its potassium content varies noticeably by cut, curing method, and brand. This calculator estimates the potassium in your serving using grams, ounces, or slices, with built-in reference values for common ham types: cured deli ham, honey ham, smoked ham, and fresh roasted lean ham. If your product differs, you can enter a custom label value in mg per 100 g.
Select a ham variety, enter your serving size, and press Calculate. The tool converts your serving to grams, applies the potassium density, and reports the result in milligrams, the percentage of the 4,700 mg Daily Value, and banana equivalents for quick comparison. It is a practical resource for dietitians, renal meal planning, and anyone comparing ham with other potassium-containing foods.

How to Use This Calculator
Start by choosing the ham type that best matches your product from the variety dropdown. The calculator uses average potassium densities from USDA FoodData Central for cured deli ham, honey ham, smoked ham, and fresh roasted lean ham. Next, enter your serving size as grams, ounces, or whole slices, and press Calculate. The results panel shows the potassium in milligrams, the percentage of the 4,700 mg Daily Value (DV), and a banana-equivalent comparison, plus a short step-by-step breakdown of the math.
If your ham has a nutrition label, choose Custom and enter the potassium value printed in mg per 100 g. This is the most accurate option because ham brands can differ by 50–80 mg per 100 g depending on the brine recipe and added seasonings.
Tip: When you measure in slices, update the grams-per-slice field to match your actual portion. A standard packaged deli slice is about 28 g, but thick-cut or shaved slices can range from 15 g to 40 g. Weighing a few slices on a kitchen scale is the fastest way to get a precise number.
Why Potassium in Ham Varies
Ham is not a single uniform food. The potassium content depends on the cut of the leg or shoulder, the curing method (dry-cured, wet-brined, or pumped with a solution), whether it is smoked or boiled, and the seasonings and additives used. Many commercial hams are "enhanced" with a salt-and-phosphate brine that is injected and tumbled into the meat; this adds water weight, which can actually lower the potassium concentration per 100 g compared with a dry-cured or freshly roasted ham.
Fresh roasted ham that has not been cured or smoked tends to keep more of the natural mineral content of the original muscle, which is why it averages around 356 mg per 100 g in USDA data. Cured deli products hover closer to 280–300 mg per 100 g. This matters on a potassium-conscious diet: a 100 g difference in intake can add up over multiple meals.
Renal note: If you are following a low-potassium meal plan for chronic kidney disease, use the custom label value whenever possible and check with your renal dietitian. Ham also contributes significant sodium, which is often the bigger concern in heart and kidney diets.
How the Calculation Works
The calculator uses one simple formula:
Potassium (mg) = serving weight (g) × potassium density (mg per 100 g) ÷ 100
Serving weight comes from your input: grams are used directly, ounces are converted with 1 oz = 28.3495 g, and slices are multiplied by the grams-per-slice value. The Daily Value percentage divides the result by 4,700 mg (the FDA adult reference amount for potassium) and multiplies by 100. The banana equivalent divides by 422 mg, the average potassium content of a medium banana.
The underlying densities are USDA averages: cured deli ham 287 mg/100 g, honey ham 296 mg/100 g, smoked ham 278 mg/100 g, and fresh roasted lean ham 356 mg/100 g. You can look up individual products in the USDA FoodData Central database at fdc.nal.usda.gov.
Worked Examples
Example 1 — Deli sandwich: 2 slices of regular cured deli ham at 28 g each = 56 g. Potassium = 56 × 287 ÷ 100 = 160.7 mg, about 3.4% of the Daily Value and roughly 0.38 banana equivalents.
Example 2 — Smoked ham: A 3 oz serving converts to 85.0 g. Potassium = 85.0 × 278 ÷ 100 = 236.5 mg, or 5.0% DV — slightly more than half a medium banana.
Example 3 — Fresh roasted lean ham: 100 g of roasted lean ham gives 356 mg, or 7.6% DV. To hit a typical 4,700 mg potassium target, you would need to eat over 1.3 kg of this ham, which shows that ham is a relatively low-potassium protein.
Example 4 — Custom label: Your deli ham label reads 330 mg per 100 g and you eat a 50 g portion: 50 × 330 ÷ 100 = 165 mg.
Reference Table: Potassium in Common Ham Products
| Ham type | mg per 100 g | mg per 3 oz (85 g) | % DV per 3 oz |
|---|---|---|---|
| Cured deli ham (regular) | 287 | 244 | 5.2% |
| Honey ham | 296 | 252 | 5.4% |
| Smoked ham | 278 | 236 | 5.0% |
| Fresh roasted ham, lean | 356 | 303 | 6.4% |

Frequently Asked Questions
Is ham considered high in potassium? No. Most ham products fall in the low-to-moderate range, roughly 280–360 mg per 100 g. For comparison, a medium banana has about 422 mg per 118 g, a baked potato about 925 mg per 173 g, and cooked salmon about 380 mg per 85 g. Ham is generally reasonable on a potassium-modified diet, though portion sizes still matter.
Why does my ham's label show a different number? Because potassium is not a required listing on all Nutrition Facts panels, many brands do not print it; when they do, the value reflects that specific brine, cure, and cut. The calculator's presets are USDA averages, not guarantees for your brand. Use the Custom field to override with label data.
Can I use this calculator for other deli meats? Not directly — turkey, chicken, roast beef, and salami each have different potassium densities. For more detail on potassium in your diet, see the NIH fact sheet at ods.od.nih.gov/factsheets/Potassium-HealthProfessional/ or the National Kidney Foundation at kidney.org.
