Added Sugar Limit Calculator
Quick answer: The American Heart Association caps added sugar at 25 g/day for women and 36 g/day for men. The 2025–2030 Dietary Guidelines go further: no amount of added sugar is considered part of a healthy diet, and no single meal should contain more than 10 g.
Enter your meals per day and this added sugar limit calculator shows the two most-cited ceilings — the American Heart Association's daily gram caps and the 2025–2030 Dietary Guidelines' 10-gram-per-meal limit — in both grams and teaspoons.
Enter your numbers
How many meals you eat — the per-meal cap scales to a daily ceiling.
Your results
| AHA limit, women | 25 g / 6 tsp |
|---|---|
| AHA limit, men | 36 g / 9 tsp |
| Dietary Guidelines limit, per meal | ≤ 10 g / 2.5 tsp |
| Dietary Guidelines daily ceiling | ≤ 30 g / 7.5 tsp at 3 meals |

How to use this calculator
Enter how many meals you eat each day. The Dietary Guidelines row scales the 10-gram-per-meal cap to a daily ceiling, while the AHA caps stay fixed since they are defined as absolute daily amounts.
Use the stricter of the two as your daily ceiling. Check Nutrition Facts labels, where added sugars are listed in grams.
How it works
Dietary Guidelines daily ceiling = meals per day × 10 g (the 2025–2030 per-meal cap). The AHA caps are fixed: 25 g (women), 36 g (men). Teaspoons ≈ grams ÷ 4.
A teaspoon of granulated sugar weighs about 4 grams, which is how the grams become the familiar 6-tsp / 9-tsp figures. Snacks count toward the per-meal cap too — the guideline applies to each eating occasion.
Worked example
3 meals per day → 3 × 10 g = 30 g per day under the 2025–2030 Dietary Guidelines (≈ 7.5 tsp); AHA caps remain 25 g (women) / 36 g (men).
Reference data
| Guideline | Limit |
|---|---|
| AHA, women | 25 g (6 tsp) |
| AHA, men | 36 g (9 tsp) |
| Dietary Guidelines 2025–2030 | No more than 10 g per meal; no amount recommended as part of a healthy diet |

Method & sources
The calculator multiplies your meals per day by the 2025–2030 Dietary Guidelines' 10-gram-per-meal cap to get a daily ceiling, then converts grams to teaspoons at about 4 grams per teaspoon. The AHA caps are fixed published values: 25 g for women, 36 g for men.
Frequently asked questions
What counts as added sugar?
Sugars added during processing or at the table — the limits do not apply to naturally occurring sugars in whole fruit or milk.
Which limit should I use?
The 2025–2030 Dietary Guidelines' per-meal cap (10 g) is now the strictest federal guidance — it replaced the old 10%-of-calories rule in January 2026. The AHA's 25 g / 36 g daily caps remain widely cited.
How many teaspoons is that?
About 4 grams of sugar per teaspoon, so 25 g ≈ 6 tsp and 36 g ≈ 9 tsp.
