What affects the calorie value
The selected boiled potato is cooked without skin, salt, butter or milk. Mash, fried potatoes and fries have different composition and need separate calculations.
Boiled potato can show more calories per 100 g than the raw record when water content changes. This does not mean boiling itself adds energy.
Vitamins and minerals per 100 g
Values come from the same USDA records. They show the amount in the food, not a percentage of an individual daily requirement.
| Nutrient | Boiled, peeled, without salt | Raw, flesh and skin |
|---|---|---|
| Potassium, mg | 328 | 425 |
| Vitamin C, mg | 7.4 | 19.7 |
| Vitamin B6, mg | 0.27 | 0.3 |
| Magnesium, mg | 20 | 23 |
| Phosphorus, mg | 40 | 57 |
| Manganese, mg | 0.14 | 0.15 |
How to calculate more accurately
For a cooked side dish, use its weight after boiling. This record contains no butter, milk or cream.
Calculate mashed potatoes as a multi-ingredient dish. Plain potato values do not represent mash with milk and butter.
The raw record includes skin. If you peel it, edible-part composition differs somewhat from this record.

How many calories are in one boiled potato?
A 167 g medium peeled boiled potato provides about 144 kcal without butter or other additions.
Can I use these values for mashed potato?

The boiled record is for peeled potato. Use a matching calculator item for potatoes cooked with skin.
