Added Sugar Calculator for Foods and Drinks
Use this added sugar calculator to total the grams of added sugar in a day’s foods and drinks from their labels, and see which items supply the most.
Tally your day’s added sugar
Shows added sugar as a share of your energy, at 4 kcal per gram. Leave blank to skip.
Foods and drinks (example day shown; replace the items with your own)
Use the “Added Sugars” line on the label, not “Total Sugars”. Servings can be decimals, such as 1.5.
Reference points, not personal targets: the FDA Daily Value for added sugars is 50 g a day on a 2,000-calorie diet. For advice about your own diet, talk to a doctor or registered dietitian.
How the added sugar calculator works
The added sugar calculator multiplies the servings you ate of each food or drink by the grams of added sugar in one serving, as printed on its label, and adds the results:
added sugar from an item = servings eaten × added sugar per serving (g)
share of an item = its added sugar ÷ total added sugar × 100
It then compares the total with the FDA Daily Value of 50 g. If you enter your daily calories, it converts the sugar to energy with the general factor of 4 kcal per gram of carbohydrate used on US labels:
% of energy = total added sugar × 4 ÷ your daily calories × 100
Items are listed with the biggest source first, so you can see at a glance where most of the sugar comes from. Rows you leave completely blank are ignored. An item that has a name but a missing or invalid value is left out and named, and the result is labelled “Subtotal (incomplete)”.
Worked example: one day’s snacks
These example label values are for illustration, not for any particular brand:
| Food or drink | Servings × added sugar | Added sugar | Share |
|---|---|---|---|
| Cola (330 mL can) | 1 × 35 g | 35 g | 51.5% |
| Fruit yoghurt | 1 × 12 g | 12 g | 17.6% |
| Breakfast cereal | 1.5 × 8 g | 12 g | 17.6% |
| Chocolate biscuit | 2 × 4.5 g | 9 g | 13.2% |
The total is 68 g, which is 136% of the 50 g Daily Value. At 4 kcal per gram that is 272 kcal, or 13.6% of a 2,000 kcal day. The one drink supplies just over half of the day’s added sugar. The shares are rounded to one decimal place, so they add up to 99.9% rather than exactly 100%.
How do total and added sugars differ?
Total Sugars counts every sugar in the food, while Added Sugars counts only the sugar put in during processing or packaged as a sweetener. On the US Nutrition Facts label, Added Sugars sits indented under Total Sugars and is already included in it. The FDA defines added sugars as sugars added during processing (such as sucrose or dextrose), foods packaged as sweeteners (such as table sugar), sugars from syrups and honey, and sugars from concentrated fruit or vegetable juices. They do not include the sugars naturally found in milk, fruits and vegetables.
That is why this tool asks for added sugars only. A glass of plain milk or a whole fruit has total sugars but no added sugars, while a sweetened drink may have almost all of its sugar listed as added. Whole dates, for example, are high in natural sugar, but that sugar is not “added”; our guide to the health benefits of dates covers them in more detail.
What are the reference limits for added sugar?
The main reference on US labels is the Daily Value of 50 g of added sugars a day, based on a 2,000-calorie diet. The FDA notes that the Dietary Guidelines for Americans recommend keeping calories from added sugars below 10% of total calories per day. Fifty grams at 4 kcal per gram is 200 kcal, which is 10% of 2,000 kcal. The added sugar calculator compares your total with this 50 g figure.
The World Health Organization uses a different term, free sugars. It advises limiting free sugars to less than 10% of total energy intake, and says that 5% or less may bring further health benefits. WHO free sugars include sugars added by the manufacturer, cook or consumer, plus sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates. The two definitions overlap but are not identical, so the added sugars on a label may not capture every free sugar, such as the natural sugar in fruit juice.
These are population reference points, not personal prescriptions. If you have diabetes or another health condition, or are planning a child’s diet, ask a doctor or registered dietitian what suits you. Our type 2 diabetes diet guide explains how sugars fit into a wider eating plan.
How do I read the label correctly?
- Check the serving size. Added sugar is listed per serving, and a pack or bottle often holds more than one. If you drank a whole bottle that holds 2 servings, enter 2.
- Match your portion. If you ate a different amount from the label serving, enter the fraction, such as 0.5 or 1.5. To turn a label serving into the portion you actually ate, the nutrition label portion calculator can help.
- Sugar you add yourself. For sugar stirred into tea or a home recipe, weigh it on a kitchen scale and enter the grams as one serving.
- Labels outside the US. Many labels list only total sugars or carbohydrates of which sugars. If there is no added sugar figure, the added sugar calculator cannot separate natural from added sugar for you.
What this calculator does not tell you
- Foods without a label. Restaurant meals, sweets from a bakery and home cooking usually carry no added sugar figure, so any number you enter is an estimate.
- Your whole diet. Added sugar is one part of a healthy pattern. Fibre, salt, fats and overall calories matter too; our sustainable weight loss guide looks at the bigger picture.
- A diagnosis or a target. The tool adds up label values and compares them with published reference points. It does not judge your health or set a limit for you.
Within those limits, the added sugar calculator is a quick way to see where the sugar in your day really comes from and which swap would make the biggest difference.

Frequently Asked Questions
Find the Added Sugars line, which is given per serving. Multiply it by the number of servings you ate, then add up every food and drink. For example, 1.5 servings of a cereal with 8 g of added sugar per serving gives 1.5 × 8 = 12 g. The added sugar calculator above does this for each item and shows the day’s total.
The FDA Daily Value for added sugars is 50 g a day, based on a 2,000-calorie diet. The FDA notes that the Dietary Guidelines for Americans recommend keeping calories from added sugars below 10% of total calories. The WHO advises keeping free sugars below 10% of energy, with further benefit below 5%. For a personal target, ask a doctor or registered dietitian.
No. The FDA says added sugars do not include the sugars naturally found in milk, fruits and vegetables. Those count in the Total Sugars line only. Table sugar, sugars added during processing, sugars from syrups and honey, and sugars from concentrated fruit or vegetable juices are counted as added sugars.
US nutrition labels use a general factor of 4 calories per gram of carbohydrate, and sugars are carbohydrates. So 68 g of added sugar supplies 68 × 4 = 272 kcal. In a 2,000 kcal day that is 272 ÷ 2,000 × 100 = 13.6% of energy. Enter your own daily calories in the calculator to see your share.
An item with a name or some values, but with servings or grams missing or not valid, is left out of the total. The calculator names it, shows the reason under the item, and labels the result “Subtotal (incomplete)” on screen and in the copied text. Fix or remove that item to get a full total. Completely blank rows are simply ignored.
