About Dark chocolate
Dark chocolate varies with the cocoa content, sugar and added ingredients. This page uses a generic catalogue estimate, not the label of a particular bar. Match the cocoa percentage and product label when you have them; the same weight of a different bar can have different calories and macros.
Also known as bittersweet chocolate.
Typical pieces and portions
Weights come from the sources below. Calories and macros are scaled from the per-100 g values on this page. Select a weight to load it into the calculator.
| Amount | Weight | Calories | Protein | Fat | Carbs |
|---|---|---|---|---|---|
| [2] | 28.4 g | 155 kcal | 1.4 g | 8.8 g | 17.3 g |
| [1] | 50 g | 273 kcal | 2.5 g | 15.5 g | 30.5 g |
What changes the numbers
- Cocoa percentage and recipe. Cocoa percentage describes the chocolate ingredients, not a calorie score. Compare the energy, fat and carbohydrate values on the actual label instead of assuming a darker bar has fewer calories.[3]
- A square is not a fixed weight. The referenced Lindt bar weighs 100 g. Half of that bar is 50 g, but a square from another mould can be a different size. Weigh your pieces or use the portion weight printed on the pack.[1]
- Plain bar or filled chocolate. The example plain-bar label lists cocoa mass, sugar, cocoa butter and vanilla. A product with nuts, fruit or a filling needs its own label values rather than the plain chocolate estimate.[1]
How to log it
Weigh the chocolate you eat. Use this estimate when no label is available; for a known brand, enter the label values in the portion calculator and use the same weight basis.

How to calculate calories in Dark chocolate
Multiply the calories per 100 g by your portion weight, then divide by 100. For the reference 30 g portion, the calculation is:
546 × 30 ÷ 100 ≈ 164 kcal
Reference portion: serving (30 g). This is an example amount, not a recommended portion. Weigh your food when possible: a cup, slice or piece can vary in size.
Check that the entry matches the food you have, including its preparation. If raw or cooked is not specified, check your label or a matching nutrition reference before logging it.
