How Many Calories Are In Redbull? | Quick Facts Guide

Calories In A Can Of The Energy Drink — By Size

The classic 8.4-ounce can lands near 110 calories, driven by sugars in the formula. Larger cans scale up nearly linearly because the recipe keeps a similar ratio of sugar to fluid. Sugar-free and Zero versions remove those sugars with non-caloric sweeteners, so their calorie line reads as 0 across sizes.

Calories By Can Size And Type

Can Size	Original Calories	Sugar-Free/Zero Calories
8.4 oz (250 ml)	~110	0
12 oz (355 ml)	~160	0
16 oz (473 ml)	~210	0
20 oz (591 ml)	~270	0

Those figures come straight from widely published nutrition panels and product listings: ~110 kcal for the 8.4-oz can, ~160 kcal for 12-oz, ~210 kcal for 16-oz, and ~270 kcal for 20-oz. The brand’s own pages confirm the standard sugar content per 8.4-oz can and caffeine range across sizes, while independent nutrient databases echo the ~110-kcal baseline for the small can. You’ll also see the 0-kcal callout on the no-sugar variants across the range. (Sources: Red Bull product pages and verified nutrition databases.)

Calories hinge on sugar. A regular 8.4-oz can lists about 27 grams of sugars; double the liquid and you’re essentially doubling the sugars, which doubles the calories. If you’re tracking intake, that’s the lever that moves the number up or down.

That sugar load adds up fast during a busy day, especially if you pair it with sweet snacks or soda. Once you scan typical labels for sugar in soft drinks, the math becomes easier to manage without guesswork.

What Drives The Calorie Number?

In the sugary version, almost every calorie comes from carbohydrates. Fat and protein are absent; vitamins and caffeine don’t contribute noticeable calories. Sugar-free and Zero swap in non-caloric sweeteners, so the label shows 0 kcal while the caffeine and B-vitamin profile stays the same.

How Much Sugar Per Can?

The 8.4-oz size lists ~27 g of sugars. Scale that up and the larger cans will sit around the mid-50-gram range for 16 oz and near 68 g for 20 oz. These are ballpark numbers you’ll see mirrored on many store-shelf labels. Red Bull’s own ingredient page notes the use of sucrose and glucose and pegs the 250-ml can at roughly that 27-g mark. Brand ingredient page.

Caffeine Counts By Size

The formula’s caffeine scales with volume. Expect around 80 mg in 8.4 oz, 114 mg in 12 oz, 151 mg in 16 oz, and 198 mg in 20 oz, according to the brand’s caffeine Q&A pages. That’s helpful when planning around daily intake limits.

Daily Limits And Smart Pairing

The U.S. Food and Drug Administration cites ~400 mg per day as a level not generally associated with negative effects for most healthy adults. If you’re sensitive, adjust lower. Check the rest of your day—coffee, tea, sodas—so you don’t stack to a number that leaves you jittery. See the FDA’s overview here: FDA caffeine guidance.

Practical Ways To Fit A Can Into Your Day

Start with size. If you want the taste with minimal calories, grab a sugar-free or Zero can. If you prefer the classic flavor, choose the smallest size that gets the job done, then plan the rest of your carbs accordingly.

Pick The Right Size For The Situation

• Short study or commute: The 8.4-oz can brings ~80 mg caffeine and ~110 kcal.
• Longer session: The 12-oz can lands at ~114 mg caffeine and ~160 kcal.
• Extended events: The 16- or 20-oz cans increase caffeine and sugars; consider sugar-free if calories are a concern.

Mind The Added Sugars Budget

Public health guidance recommends keeping added sugars under 10% of daily calories. On a 2,000-calorie plan, that’s about 50 grams per day. One large sugary can can claim that entire budget. See the quick fact sheet here: Dietary Guidelines added sugars.

Label Clues: How To Read This Can Fast

Flip the can and look for three lines: calories, total sugars (and “includes added sugars”), and caffeine. Those three lines tell you almost everything about the role this drink plays in your day. If the can is sugar-free or Zero, the calorie line will show 0 while the caffeine line matches the sugary version of the same size.

Edition Flavors Vs. Nutrition

Seasonal and color “Edition” flavors generally keep the same nutrition pattern as their parent style. A sugary Edition of the 8.4-oz can still sits near 110 kcal, and the sugar-free Edition reads 0 kcal. Always check the panel, since flavors can shift sodium or vitamin amounts slightly from can to can.

How This Drink Compares To Other Energy Cans

If you’re choosing between popular options, the calorie spread often tracks with sugars and size. Here’s a quick look at standard cans across the aisle.

Calories Across Popular Energy Drinks

Brand & Size	Calories	Notes
Monster, 16 oz	~230	~54 g sugars per label
Rockstar, 16 oz	~260*	Some labels list ~130 per 8 oz serving
Celsius, 12 oz	~10	Low-cal flavors widely sold

*Many Rockstar labels show “per 8 oz” serving; the 16-oz can lists two servings. Always multiply by servings per container for the true total.

Quick Answers To Common Calorie Questions

Is The Small Can Healthier?

It’s lighter on sugars and calories because it’s smaller. If you only need a short lift, the 8.4-oz can trims the calorie hit by design.

Does Sugar-Free Taste Different?

Yes, the flavor shifts because the sweeteners aren’t sucrose or glucose. Nutrition-wise, you get the same caffeine with 0 kcal. If calories or sugars are your main concern, that’s the simplest swap.

What About Late-Night Use?

Caffeine timing matters. Many people sleep better when they stop caffeine in the late afternoon. If you’re sensitive, move your last can earlier in the day.

Sources, Verification, And Notes

Calorie values for the original formula align across nutrition databases and retailer labels: ~110 kcal (8.4 oz), ~160 kcal (12 oz), ~210 kcal (16 oz), and ~270 kcal (20 oz). Red Bull’s product pages confirm the sugar presence in the regular can and the no-sugar formulation of Sugar-free and Zero, along with caffeine amounts that scale by size. Independent databases such as MyFoodData list the 8.4-oz can at ~111 kcal; major grocers list the larger cans at the numbers shown above.

Bottom Line For Everyday Use

If you want the flavor with minimal calories, choose sugar-free or Zero. If you want the classic taste, pick the smallest can that meets your caffeine need and plan sugars elsewhere in your day. Want a deeper walk-through of daily sugar targets? Try our daily added sugar limit.
