Peaches are more than a sweet summer treat — they’re also a useful source of potassium, a mineral that helps regulate blood pressure, nerve signaling, muscle contractions, and fluid balance. A medium raw peach delivers close to 285 mg of potassium, roughly 6% of the 4,700 mg Daily Value. This calculator turns any peach serving into a quick potassium estimate.
Enter the amount you’re eating and choose a serving unit — whole medium or large peaches, sliced cups, grams, or ounces. The tool starts with the USDA value of 190 mg of potassium per 100 g of raw peach, and you can edit that number to match a canned, frozen, or dried product’s label. Results include total potassium, percent Daily Value, and a full weight breakdown.
Use it for blood pressure monitoring, kidney-friendly meal planning, sports nutrition, or everyday food tracking — the answer appears in seconds.

Why Peach Potassium Matters
Potassium is an essential electrolyte that partners with sodium to keep your cells, nerves, and muscles working properly. Getting enough potassium can help support healthy blood pressure, especially when your salt intake is high. For active people, the mineral also plays a role in muscle contraction and post-exercise recovery, which is why bananas get so much attention from athletes — but peaches are a lower-calorie option with a respectable potassium punch.
One medium peach (about 150 g) supplies roughly 285 mg of potassium, or 6% of the 4,700 mg Daily Value used by the FDA for nutrition labeling. That may not sound dramatic, but it adds up quickly: a two-peach snack, a cup of sliced peaches, or peaches added to oatmeal or yogurt can contribute a meaningful share of your daily target.
How to Use This Calculator
- Type an amount in the Amount field. You can use decimals for half peaches or partial cups.
- Select the serving unit that matches your food: medium peach, large peach, cup sliced, grams, or ounces.
- Adjust the potassium-per-100g field only if you're using a product with a different label value, such as canned peaches in syrup or dried peach slices.
- Click Calculate to see total potassium, percent Daily Value, estimated weight, and a step-by-step breakdown.
The quick-fill buttons give you a one-tap way to check common servings: 1 medium, 1 large, 1 cup sliced, or 100 g. Use the Copy result button to paste the output into a food diary or nutrition note.
How the Math Works
Every peach serving is first converted to grams. The calculator uses these standard weights: a medium peach = 150 g, a large peach = 175 g, 1 cup of sliced peaches = 154 g, 1 ounce = 28.35 g, and 1 gram = 1 g. With the weight in grams, it applies the potassium density of the peach.
Example: For 1 cup of sliced peaches (154 g) at the default 190 mg/100g, the math is 154 × 190 ÷ 100 = 292.6 mg, which is 292.6 ÷ 4,700 × 100 = 6.2% DV. This is exactly what the calculator computes for you.
Peach Potassium Reference Table
The table below assumes raw peaches with skin at 190 mg potassium per 100 g, using USDA reference data.
| Serving | Weight | Potassium | % DV |
|---|---|---|---|
| 1 small peach | 130 g | 247 mg | 5.3% |
| 1 medium peach | 150 g | 285 mg | 6.1% |
| 1 large peach | 175 g | 333 mg | 7.1% |
| 1 cup sliced peaches | 154 g | 293 mg | 6.2% |
| 100 g raw peach | 100 g | 190 mg | 4.0% |
| 1 oz peach | 28.35 g | 54 mg | 1.1% |
For canned peaches, always check the Nutrition Facts label because syrup pack, juice pack, and water pack change both the potassium and added sugar.
Factors That Affect Accuracy
Potassium content in peaches naturally varies with variety, ripeness, soil, and growing region. A white-flesh peach may have slightly different minerals than a yellow-flesh peach, and a very ripe fruit often has a higher sugar content but similar potassium. Peeling removes part of the fruit's fiber and some nutrients, though potassium is mostly inside the flesh.
Frequently Asked Questions
How much potassium is in one medium peach?
A medium raw peach weighing about 150 g contains about 285 mg of potassium, which is roughly 6% of the 4,700 mg Daily Value. A large peach pushes that closer to 333 mg.
Can I use this calculator for canned or frozen peaches?
Yes. Canned peaches packed in water or juice usually have a lower potassium density per 100 g than raw peaches, while dried peaches are much more concentrated. Adjust the potassium-per-100g field to the value on your product's label for a better estimate.
Are peaches considered a high-potassium food?
Not generally. Peaches are classified as a moderate potassium fruit. One medium peach provides about 6% DV, whereas a medium banana provides about 9–12% DV. Peaches can still fit into most well-planned diets, including many potassium-conscious eating patterns.
Does peeling remove the potassium?
Most of the potassium in a peach is in the flesh, so peeling has only a small effect on total potassium. The skin does hold some potassium along with fiber, so keeping the skin on is a slightly better choice for potassium and overall nutrition.
