Ever wondered how much sugar is hiding in your favorite cocktail? This calculator estimates the sugar content per 100 grams (and per serving) of any mixed drink. Whether you're tracking macros, managing blood sugar, or just curious about your happy hour choices, this tool gives you a quick, data-driven answer.
Simply enter the volume of each ingredient (juice, syrup, soda, liqueur, etc.) and its sugar concentration. The calculator sums up the total sugar, then divides by the total weight to give you grams per 100g — the standard nutrition label format. You'll also see the sugar per serving and a helpful sweetness category.
Perfect for nutritionists, fitness enthusiasts, and anyone following a low-sugar diet. Use it to compare cocktails, tweak recipes, or plan your next drink with confidence.

How to Use This Tool
Start by entering the volume of each ingredient in your cocktail. You can switch between milliliters (ml) and fluid ounces (oz) using the dropdown next to each volume field. Then, enter the sugar content of that ingredient, either in grams per 100 ml or teaspoons per 100 ml. If you're unsure about a value, use the quick-add preset buttons for common ingredients like spirits, cola, simple syrup, triple sec, and lime juice — they'll fill in the last row for you.
Add as many ingredients as your recipe needs by clicking the + Add Ingredient button. Remove any row with the red Remove button. Once all ingredients are listed, hit Calculate. The tool sums up the total sugar and total weight (assuming a density of 1 g/ml for simplicity), then computes the sugar per 100 grams — the standard metric used on nutrition labels. You'll also see the total sugar per serving and a sweetness category (low, moderate, or high) to help you interpret the result at a glance.
Note: The calculator assumes a density of 1 g/ml for all liquids. In reality, syrups and liqueurs are denser, but for most mixed drinks this approximation is accurate enough for dietary tracking.
Formula Explained
The core calculation is straightforward:
Sugar per 100g = (Total Sugar in grams ÷ Total Weight in grams) × 100
For each ingredient, the sugar contribution is calculated as:
Sugar (g) = (Sugar per 100ml ÷ 100) × Volume (ml)
If you enter sugar in teaspoons per 100 ml, the tool converts it to grams using the standard conversion of 1 teaspoon = 4.2 grams of sugar. This is the same conversion used by the USDA for granulated sugar.
Total weight is simply the sum of all ingredient volumes (in ml), since 1 ml of water weighs 1 gram. This is a reasonable approximation for most cocktail ingredients, though syrups and cream-based liqueurs will weigh slightly more.
Worked Examples
Example 1: Rum and Coke
Ingredients: 50 ml rum (0 g sugar), 150 ml cola (10 g sugar per 100 ml).
Rum sugar: (0/100) × 50 = 0 g. Cola sugar: (10/100) × 150 = 15 g. Total sugar = 15 g. Total weight = 200 g. Sugar per 100g = (15/200) × 100 = 7.5 g/100g. Category: Moderate.
Example 2: Margarita
Ingredients: 50 ml tequila (0 g), 30 ml triple sec (25 g/100ml), 30 ml lime juice (8 g/100ml).
Tequila: 0 g. Triple sec: (25/100) × 30 = 7.5 g. Lime juice: (8/100) × 30 = 2.4 g. Total sugar = 9.9 g. Total weight = 110 g. Sugar per 100g = (9.9/110) × 100 = 9.0 g/100g. Category: Moderate.
Tips & Best Practices
- Use accurate sugar values: Check the nutrition label of your mixer or syrup. Many brands list sugar per 100 ml, which you can enter directly.
- Watch out for hidden sugars: Tonic water, fruit juices, and pre-made sour mixes can be surprisingly high in sugar. A classic gin and tonic with 200 ml of tonic can contain 18-20 g of sugar.
- Compare alternatives: Use this calculator to compare a standard cocktail with a low-sugar version (e.g., using diet soda or fresh citrus instead of syrup). You'll often see a dramatic difference.
- Consider alcohol calories: This tool only measures sugar, not alcohol. Alcohol itself contributes calories (7 kcal/g) and can affect blood sugar, so factor that in separately if you're tracking total intake.
Factors Affecting Accuracy
The main limitation is the density assumption. Syrups (like simple syrup or grenadine) have a density around 1.3 g/ml, and cream liqueurs can be even denser. If you're using a lot of these, the actual weight will be higher than calculated, which would lower the sugar per 100g slightly. For most cocktails, however, the error is under 5%.
Another factor is the sugar content of fresh ingredients. Lime and lemon juice contain about 2-3 g of sugar per 100 ml, but this varies with ripeness. The preset value of 8 g/100ml for lime juice is a conservative estimate that includes the natural sugars plus any added sweetener in commercial lime juice.
Finally, remember that sugar per 100g is a concentration, not a total. A small, sweet shot can have a high per-100g value but a low total sugar, while a large, moderately sweet drink can have a lower per-100g value but more total sugar. Always consider both numbers.
Frequently Asked Questions
How many grams of sugar are in a typical cocktail?
It varies widely. A spirit on the rocks has 0 g, while a Piña Colada can exceed 30 g. Most classic cocktails like a Margarita or Daiquiri fall in the 10-20 g range. This calculator helps you get a precise number for your specific recipe.
Is sugar per 100g the same as sugar per 100ml?
Not exactly. Since 100 ml of a liquid weighs about 100 g (for water-like drinks), the numbers are nearly identical for most cocktails. But for dense syrups, 100 ml weighs more than 100 g, so the per-100g value would be lower than the per-100ml value. This tool converts everything to weight-based per 100g for consistency with nutrition labels.
Can I use this for non-alcoholic drinks?
Absolutely. The calculator works for any beverage — mocktails, smoothies, or even coffee drinks. Just enter the ingredients and their sugar content.
Where can I find sugar content for my ingredients?
Check the nutrition facts panel on bottles and cans. For fresh ingredients, the USDA FoodData Central database is an excellent resource. You can also use our coffee sugar calculator for coffee-based drinks, or bread sugar calculator for baked goods.
