Daily Sugar Limit Calculator — Three Rulers, Three Numbers
There is no single American number for a daily sugar limit — there are three, from three institutions answering different questions. The strictest and most quotable is the American Heart Association’s: 25 g a day for women, 36 g for men. The tool below shows the World Health Organization ceiling, which is the international reference; the US rulers are compared right under it.
Daily limit for free sugars
—g/day
WHO limit: at most 10% of calories (≈50 g in a 2,000 kcal diet); ideally below 5% (≈25 g).
The three limits, side by side
| Source | Limit for added sugar | What kind of number it is |
|---|---|---|
| American Heart Association | 36 g/day men, 25 g/day women (under 6% of calories) | A cardiovascular health target |
| FDA Nutrition Facts label | 50 g/day Daily Value | A labeling reference, 10% of 2,000 kcal |
| Dietary Guidelines 2025–2030 | No more than 10 g of added sugar in any one meal | A per-meal rule, new in this edition |
| WHO (shown in the tool above) | Under 10% of calories, ideally under 5% | An international population target |
The AHA figures come with teaspoons attached, which is the more usable unit: 9 teaspoons for men, 6 for women. The association also reports that Americans aged 2 and up currently get about 12 to 13 percent of daily calories from added sugar — roughly double its own recommendation of under 6 percent.
What changed in the 2025–2030 Guidelines
This is the number most sugar pages still get wrong. Earlier editions of the Dietary Guidelines set a daily cap of less than 10 percent of calories from added sugars, and the FDA’s 50 g Daily Value was derived from exactly that rule. The 2025–2030 edition, published in January 2026, replaced the daily percentage with a per-meal rule: no amount of added sugar is considered part of a healthy diet, and one meal should contain no more than 10 grams of added sugars.
It also set snack limits tied to the FDA “Healthy” claim — grain snacks such as crackers should not exceed 5 g of added sugar per half-ounce whole-grain equivalent, and dairy snacks such as yogurt should not exceed 2.5 g per half-cup equivalent.
The FDA label rule has not followed. Nutrition Facts panels still carry a 50 g Daily Value, and the FDA’s own explainer still cites the older “less than 10 percent of total calories” framing. So a package can read 20% DV — 10 g — and be simultaneously a fifth of the label’s allowance and the entire allowance for that meal under the current Guidelines.
For completeness: the Dietary Reference Intakes carry a separate figure, added sugars limited to no more than 25 percent of total energy. That one is a nutrient-dilution ceiling — the point at which sugar starts crowding out nutrients — not a cardiovascular target, and it is far above every other number on this page. Do not read it as permission.
Added sugar is not all sugar
Every limit here applies to added sugar only:
- Counted: table sugar, honey, molasses, syrups, sugars added in processing, and sugars from concentrated fruit or vegetable juice.
- Not counted: the sugar naturally present in whole fruit, vegetables and plain milk.
The distinction is real, not a technicality. Sugar in an orange arrives with fiber, water and structure that change how fast it is absorbed; the same grams in orange juice do not. The FDA draws the line the same way on the label, which is why the “Total Sugars” line has no Daily Value at all and only “Added Sugars” does.
Where it actually accumulates
The AHA’s ranking of US sources is blunt: sugar-sweetened beverages are about 24 percent of all added sugar, and desserts and sweet snacks about 19 percent. The association puts one 12-ounce can of regular soda at 10 teaspoons of sugar and 160 calories — past a woman’s entire daily cap of 6 teaspoons, past a man’s 9, and several times the 10 g per-meal rule.
Two practical consequences follow. Cutting drinks first moves the number more than anything else on a label. And reading ingredient lists helps, because added sugar hides behind names: the FDA lists high-fructose corn syrup, agave syrup, corn syrup, rice syrup, fructose, glucose, dextrose, sucrose, cane sugar, beet sugar, turbinado sugar, maltose, fruit juice concentrate, honey and molasses among them.
Fiber is the other half of the same plate — it slows absorption and it is what whole fruit has that juice does not. See the daily fiber intake numbers. The other label ceiling that behaves the same way, with a federal number and a stricter AHA one, is the daily sodium limit. And because every percentage-of-calories rule needs your calorie total first, the daily calorie calculator is the starting point.

Frequently asked questions
How many grams of added sugar per day is the limit?
The American Heart Association caps added sugar at 36 g (9 teaspoons) a day for men and 25 g (6 teaspoons) for women. The FDA Daily Value used on labels is 50 g. They are different rulers, and the AHA one is the strictest.
What counts as added sugar?
Sugars added during processing, table sugar, honey, syrups, and sugars from concentrated fruit or vegetable juice. Sugars naturally present in plain milk, whole fruit and vegetables are not added sugars and are not part of the limit.
How much sugar is in a can of soda?
The American Heart Association puts a 12-ounce can of regular soda at 10 teaspoons of sugar and 160 calories. That is past the 6-teaspoon daily cap for women and past the 9-teaspoon cap for men, from one drink.
Does fruit sugar count toward the limit?
Whole fruit does not — the sugar arrives with fiber and water, and the FDA excludes it. Concentrated fruit juice is different: the FDA counts sugars from it as added sugars, and the 2025-2030 Guidelines tell you to avoid sugar-sweetened beverages including fruit drinks.
Why does the label say 50 g when the AHA says 25?
The 50 g figure is the FDA Daily Value, a single labeling reference set at 10 percent of a 2,000-calorie diet. It is a regulatory yardstick for the %DV column, not a health target, and the AHA recommends a lower ceiling of about 6 percent of calories.
