How it works
Added sugar hides in many foods and drinks, and this calculator shows how your intake compares to recommended limits. You enter your daily added sugar in grams and your sex, and it returns the recommended limit, how many grams you are over, and the calories that sugar provides. The American Heart Association recommends men consume no more than 36 grams, or 9 teaspoons, of added sugar per day, and women no more than 25 grams, or 6 teaspoons. Added sugars are those put into foods during processing or preparation, as distinct from the natural sugars in fruit and milk. They provide calories with no nutritional value, and high intake is linked to weight gain, type 2 diabetes, heart disease, and tooth decay. The biggest source for many people is sugar-sweetened beverages like soda, which can contain more than a day's limit in a single can. Because each gram of sugar carries about 4 calories, cutting added sugar is an efficient way to reduce empty calories. Nutrition labels now list added sugars separately, making it easier to track. A negative amount over means you are within the limit. Use the result to identify how much to cut, focusing first on sugary drinks and sweets. Enter your added sugar and sex to see how you compare.
Amount over = intake − limit (36 g men / 25 g women); calories = grams × 4
The American Heart Association recommends no more than 36 grams of added sugar per day for men and 25 grams for women. The amount over is your intake minus that limit, and the calories from sugar are your grams multiplied by 4, since each gram of sugar provides about 4 calories.

Frequently asked questions
How much added sugar is too much?
The American Heart Association recommends a daily limit of 36 grams, about 9 teaspoons, for men, and 25 grams, about 6 teaspoons, for women. These refer to added sugars, not the natural sugars in whole fruit or milk. The calculator compares your intake to the limit for your sex and shows how far over you are.
What is the difference between added and natural sugar?
Added sugars are put into foods and drinks during processing or preparation, such as the sugar in soda, candy, and baked goods. Natural sugars occur inside whole foods like fruit and milk, which also provide fiber, vitamins, and minerals. Guidelines focus on limiting added sugars because they add calories without accompanying nutrients.
Why is added sugar bad for you?
Added sugar provides calories with essentially no nutritional value, and high intake is associated with weight gain, type 2 diabetes, heart disease, fatty liver, and tooth decay. Sugary drinks are especially concerning because the body does not register their calories as fullness, making it easy to overconsume. Reducing added sugar improves overall diet quality.
How many calories are in a gram of sugar?
Each gram of sugar provides about 4 calories, the same as other carbohydrates. So 25 grams of added sugar contributes roughly 100 calories, and 50 grams about 200. Because these are empty calories with no nutrients, cutting added sugar is an efficient way to reduce calorie intake without sacrificing nutrition.
Where should I cut added sugar first?
Start with sugar-sweetened beverages such as soda, sweetened coffee drinks, energy drinks, and fruit drinks, which are the largest single source for many people and can exceed a day's limit in one serving. Then look at candy, desserts, sweetened cereals, and flavored yogurts. Reading labels for added sugars helps you spot hidden sources.
