How many calories are in Coca-Cola Zero?
A 12 fl oz can of Coca-Cola Zero Sugar holds 0 calories, and the USDA record puts it at 0 calories per 100 g as well. There is nothing to scale here: the mini can, the 20 oz bottle and the Cherry Zero version all land on the same zero. The one line that moves is sodium.

Coca-Cola Zero quick facts
The record used here is the USDA Branded entry 2596996, "COCA-COLA ZERO SUGAR CANS, 12 FL OZ, 24 PACK", the label behind GTIN 0049000043006. That is the format most people are actually holding in the United States: a single 12 fl oz can, 355 g of liquid, pulled out of a fridge pack.
There is one older SR Legacy entry that looks like a match in a USDA search, and it is not this drink. More on that trap further down, because it is the one way you can end up quoting calories for a can that has none.
| Nutrient | Per 100 g | Per 1 can, 12 fl oz (355 g) | % Daily Value |

| Total fat | 0 g | 0 g | 0% |
| Carbohydrate | 0 g | 0 g | 0% |

Verified nutrition data
Numbers on this page come from USDA FoodData Central, the U.S. Department of Agriculture’s food composition database, and from manufacturer labels where a branded product is named. Last verified September 2026. How we verify our data →
Four rows that normally sit on a US Nutrition Facts panel are absent above: saturated fat, dietary fiber, total sugars and added sugars. The USDA Branded edition of this label carries no value in any of those fields, so they are left out rather than filled with a zero we cannot source. The carbohydrate line is declared, and it reads 0 g, which is the number that answers the sugar question in practice. Cholesterol and potassium are also undeclared on this record.
A word on what "zero" means on a label. FDA rules let a beverage be declared as 0 calories when the amount per serving is below a small threshold, so "zero" is a label term, not a physics claim. The Daily Value reference amounts used in the percentage column above come from the same FDA labeling rules.
US servings from a mini can to a 20 oz bottle
| Serving | Weight | Calories |
|---|---|---|
| 1 oz | 28.4 g | 0 kcal |
| 1 mini can, 7.5 fl oz | 222 g | 0 kcal |
| 1 bottle, 8.5 fl oz | 251 g | 0 kcal |
| 1 can, 12 fl oz | 355 g | 0 kcal |
| 1 bottle, 20 fl oz | 591 g | 0 kcal |
| Per 100 g | 100 g | 0 kcal |
The 12 fl oz can, the 7.5 fl oz mini can and both bottles are USDA label servings, each one attached to its own Branded record. The 1 oz line is our own arithmetic from the USDA 100 g figure, not a USDA serving, and it is there only because ounce-by-ounce logging is how some tracking apps handle liquids.
This is the part that is genuinely different from a sugar-sweetened cola. With regular soda, the size of the cup is the whole story, and going from a mini can to a 20 oz bottle multiplies the number by more than two and a half. Here the multiplier lands on zero every time, so choosing the big bottle costs you nothing in calories. It does cost you sodium, and it costs you the same volume of liquid in your daily fluid budget.
One practical note for anyone logging by weight instead of volume: 12 fl oz of this drink is treated as 355 g, close enough to water that the milliliter and gram figures are used interchangeably on the USDA record.
Cans bottles and Cherry Zero
Five separate USDA records cover the formats in the table below, plus one lookalike that is not the cola at all.
| Format | Calories per 100 g | Serving | Calories | Sodium |
|---|---|---|---|---|
| Zero Sugar can, 12 fl oz | 0 | 1 can, 355 g | 0 kcal | 39 mg |
| Zero Sugar Starlight bottle, 20 fl oz | 0 | 1 bottle, 591 g | 0 kcal | 95 mg |
| Zero Sugar mini can, 7.5 fl oz | 0 | 1 mini can, 222 g | 0 kcal | not declared |
| Zero Sugar bottle, 8.5 fl oz | 0 | 1 bottle, 251 g | 0 kcal | not declared |
| Cherry Zero bottle, 20 fl oz | 0 | 1 bottle, 591 g | 0 kcal | not declared |
| NOS Zero energy drink, not a cola | 4 | 16 fl oz, 480 g | 19 kcal | 408 mg |
The calorie column is flat across every genuine Coca-Cola Zero Sugar format, and that includes the cherry version, which builds its flavor on the same zero base. USDA also carries a 16 fl oz can under record 2211941 at the same zero. The mini can and the 8.5 fl oz bottle records show 0 mg of sodium, which almost certainly means the field was left undeclared rather than the drink being sodium-free, so those cells are marked instead of quoted.
The last row is the reason this section exists. Search USDA for this brand and you will surface record 174809, an SR Legacy entry for a sugar-free NOS energy drink made by the same company. It runs 4 calories per 100 g, which is 19 calories in a 16 fl oz serving, and 85 mg of sodium per 100 g, roughly 7.7 times the 11 mg per 100 g in the Zero Sugar can. Log it by accident and you have given a zero-calorie soda a calorie count and nearly eight times the sodium.
Sodium is the only number that moves
Everything else on this label sits still. Sodium does not. The can is 11 mg per 100 g, which comes to 39 mg for 355 g, or 2% of the 2,300 mg Daily Value. That is small, and it scales with the container.
USDA's own 20 fl oz Starlight bottle record lists 16 mg per 100 g, which works out to 95 mg in the 591 g bottle, 4% of the Daily Value. Take the can's 11 mg per 100 g and scale it to the same 591 g instead and you get 65 mg, our own arithmetic from the 100 g figure. The gap between 65 and 95 is a difference between two label declarations, not a difference in the drink, and it is a good reminder that Branded records are transcriptions of packaging rather than lab analyses.
Put it in daily terms. Six 12 oz cans across a day come to 234 mg of sodium, about a tenth of the Daily Value, which is not the part of a soda habit worth worrying about when the Dietary Guidelines for Americans place the sodium problem squarely in packaged and restaurant food. If you are watching sodium closely, the can is the lighter pick per ounce than the 20 oz bottle, but the difference is measured in tens of milligrams.
How does Coca-Cola Zero compare?
The useful comparison is not with regular cola, where the gap is obvious, but with the other drinks people reach for when they want flavor without calories.
| Drink | Per 100 g | US serving | Calories |
|---|---|---|---|
| Coca-Cola Zero Sugar | 0 kcal | 1 can, 12 fl oz (355 g) | 0 kcal |
| Sugar-free energy drink | 4 kcal | 8 fl oz (240 g) | 10 kcal |
| Diet green tea, ready to drink | 4 kcal | 1 cup (240 g) | 10 kcal |
| Diet cranberry juice drink | 4 kcal | 8 fl oz (240 g) | 10 kcal |
Our take: Coca-Cola Zero Sugar is the only line in this table that reads 0 per 100 g, and the other three all sit at 4 calories per 100 g, or 10 calories in an 8 fl oz pour. Three glasses of the diet tea come to 30 calories, which is real but trivial, so the choice between these four is about caffeine, taste and sodium rather than calories. If you are cutting and you want a cola, this is the cheapest way to have one. If you are trying to feel full, none of them will do it, and a glass of milk or a piece of fruit will do more for the same handful of calories than any zero-calorie soda can.

Coca-Cola Zero FAQs
How many calories are in a can of Coca-Cola Zero?
Zero: a 12 fl oz can (355 g) carries 0 calories, and the USDA Branded record behind it lists 0 calories per 100 g. The only nutrient with a number on that record is sodium: 11 mg per 100 g, which works out to 39 mg in the can, 2% of the Daily Value.
Does Coca-Cola Zero have sugar?
The carbohydrate row is 0 g per 100 g and 0 g in a 12 fl oz can, so there is no carbohydrate left for sugar to sit in. The USDA Branded record declares no total sugars and no added sugars value at all, so no sugar figure is quoted on this page.
How many calories are in a 20 oz Coca-Cola Zero?
Still 0. The 20 fl oz bottle weighs 591 g and stays at 0 calories, because the drink is 0 calories per 100 g and multiplying zero by a bigger pour changes nothing. Sodium does move: the USDA 20 fl oz record lists 16 mg per 100 g, or 95 mg for the bottle, 4% of the Daily Value.
How many calories are in Cherry Coke Zero?
Zero again: the USDA record for the Coca-Cola Cherry Zero 20 fl oz bottle shows 0 calories per 100 g, so the full 591 g bottle is 0 calories. The cherry flavor rides on the same zero base as the plain version, and sodium is not declared on that record, so no sodium figure is given for it.
How much sodium is in Coca-Cola Zero?
39 mg in a 12 fl oz can, scaled from 11 mg per 100 g on the USDA record. That is 2% of the 2,300 mg Daily Value. The 20 fl oz bottle record lists 16 mg per 100 g, or 95 mg per bottle, 4% of the Daily Value. Six cans in a day would total 234 mg.
Is Coca-Cola Zero keto friendly?
A can contributes 0 calories and 0 g of carbohydrate, so it fits inside a carb-limited day without using any of the allowance. The USDA record lists no sugars value and no fiber value, so net carbs cannot be calculated from it, but the carbohydrate line itself already reads zero.
Does Coca-Cola Zero break a fast?
A 12 fl oz can supplies 0 calories, so by the calorie definition of a fast it adds nothing at all. Fasting rules that also exclude sweeteners are a separate question, and the USDA record carries no data on it: the record lists calories, macros and 39 mg of sodium per can.
How much caffeine is in Coca-Cola Zero?
No number is quoted here, because the USDA Branded record for the 12 fl oz can lists calories, macronutrients and sodium but carries no caffeine value. The Nutrition Facts panel and ingredient list printed on the can are where to read it. If a field is missing from the record, it stays off this page.
