How many carbs are in dark chocolate?
A 1.45 oz dark chocolate bar (41g) has about 25g of carbohydrate and 22g of net carbs. The higher cocoa content means more fiber than milk chocolate, but the carb count is still substantial.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 dark chocolate bar (41g / 1.45 oz) | 24.8g | 2.7g | 22.1g |
| 1 bar (17g) | 10.3g | 1.1g | 9.2g |
| 1 blocks (42g) | 25.4g | 2.7g | 22.7g |
| 100 grams | 60.5g | 6.5g | 54.0g |
Net carbs
A 1.45 oz dark chocolate bar has about 22g of net carbs, which is total carbs (25g) minus fiber (2.7g). The fiber is meaningfully higher than milk chocolate because of the greater cocoa solids content. See the net carbs guide for context on the net carbs calculation.
Glycemic index of dark chocolate
The glycemic index of dark chocolate is about 23. Dark chocolate with a high cocoa percentage has a low glycemic index. The fat, fiber, and polyphenols in cocoa solids all slow glucose absorption. Lower-cocoa dark chocolate bars are closer to 40.
For diabetes
A full 1.45 oz dark chocolate bar has about 25g of carbs, which is a real meal-sized carb load. However, the low glycemic index means the blood sugar rise is slower and more gradual than with equal carbs from most other sweets. A smaller serving of two to three squares (about 14g) cuts the carbs to roughly 8g and is often more practical. Count by weight, not by bar, since bar sizes vary significantly. See the diabetes carb-counting guide.
Keto and low carb
A full 1.45 oz dark chocolate bar has about 22g of net carbs, which exhausts most keto daily budgets. A small portion of 10 to 15g (about one to two squares) has 6 to 9g of net carbs and can fit into a keto plan if you plan around it. Bars at 85% cocoa or higher have fewer net carbs per gram than 70% bars.
Good to know
Cocoa percentage is the most important variable. A 70% dark chocolate bar has around 40g of sugar per 100g. An 85% bar drops that to about 20g and adds more fiber. A 99% bar has under 5g of sugar per 100g. The USDA data here is for a Special Dark bar, which is approximately 60% cocoa. Cacao nibs, which are unsweetened crushed cocoa beans, have only about 10g of carbs per 100g and can substitute in recipes.

How many carbs are in dark chocolate?
A 1.45 oz dark chocolate bar (41g) has about 25g of carbs and 22g of net carbs. Per 100g, dark chocolate has about 60g of carbs.
Is dark chocolate keto?
A full bar is not keto. A small portion of one to two squares (about 10 to 15g) has 6 to 9g of net carbs and can fit keto if portioned carefully. Higher cocoa percentage means fewer net carbs per gram.
How many carbs does 85% dark chocolate have?
An 85% dark chocolate bar typically has about 15 to 20g of carbs per 40g serving and about 3 to 4g of fiber, so roughly 11 to 17g of net carbs.
Is dark chocolate better than milk chocolate for blood sugar?
Yes, in most cases. Dark chocolate has a lower glycemic index, more fiber, and less added sugar per gram, so the blood sugar response tends to be slower and smaller.
How many carbs are in 1 oz of dark chocolate?
One ounce (28g) of dark chocolate at roughly 60% cocoa has about 17g of carbs and 15g of net carbs.
