This cocktail sugar calculator estimates the added sugar in your favorite mixed drinks by adding up the sugar from syrups, juices, sodas, and liqueurs. Cocktails can hide 10–40 grams of sugar per serving, often as much as a can of soda, even when they don't taste especially sweet.
Choose a preset like Margarita, Mojito, or Piña Colada, adjust ingredient amounts to match your own recipe, and the calculator returns sugar per drink, total sugar for your batch, teaspoon equivalents, and the percentage of the FDA daily value for added sugars. You can also build a fully custom drink by entering any combination of ingredients and volumes.
This is a handy tool for anyone tracking added sugar, counting calories from drinks, or simply curious about what is in their glass during happy hour.
🍹 Estimate Sugar in Your Cocktail
Enter ingredients per drink, then set the number of drinks. Leave unused ingredient rows blank.
1. Pick a recipe or build your own
2. Sugar-containing ingredients (per drink)
Spirits straight up contain negligible sugar and can be ignored here.
Step-by-Step Guide
Start with the preset dropdown if you want a familiar drink, then tap Load preset to fill the ingredient rows automatically. You can edit any row afterward to match your own pour or house recipe. If you prefer to build from scratch, leave the preset on Custom drink and enter each sweet ingredient manually.
- Choose a preset or enter a custom combination of ingredients.
- Type the amount used per drink and pick the correct unit — milliliters or fluid ounces.
- Set the number of drinks you plan to make so the batch total is meaningful.
- Press Calculate sugar and review the per-drink and batch results.
How the Sugar Estimate Is Calculated
Each ingredient is assigned a sugar density in grams per 100 ml, using average values drawn from USDA FoodData Central and standard bar references. The calculator first converts ounces to milliliters (1 fl oz = 29.5735 ml), then applies a simple density formula:
For example, 30 ml of simple syrup with a density of 0.60 g/ml contributes 30 × 0.60 = 18 g of sugar. Since real brands vary — some tonics contain more sweetener than others, and fruit juices differ by variety — the result is a practical estimate rather than a laboratory measurement.

Worked Example
The Margarita preset uses three sweet components: 30 ml lime juice, 30 ml triple sec (counted as liqueur), and 15 ml simple syrup. Here is how the totals build up:
- Lime juice: 30 ml × 0.02 g/ml = 0.6 g
- Triple sec: 30 ml × 0.30 g/ml = 9.0 g
- Simple syrup: 15 ml × 0.60 g/ml = 9.0 g
Total = 18.6 g of sugar per drink. That is about 4.4 teaspoons and roughly 37% of the FDA daily value for added sugar on a 2,000-calorie diet. Make a pitcher with 6 servings and the batch total jumps to about 112 g.
Standard Sugar Reference
The table below shows the typical sugar densities used by this calculator. Use it to estimate a drink before you even open the app.
| Ingredient | Sugar (g per 100 ml) |
|---|---|
| Honey | 80 |
| Agave nectar | 70 |
| Simple syrup | 60 |
| Grenadine | 50 |
| Liqueurs (triple sec, amaretto) | ~30 |
| Sweet & sour mix | ~25 |
| Coconut cream | ~20 |
| Cola | 11 |
| Fruit juice | ~10 |
| Ginger beer | ~10 |
| Tonic water | ~8 |
| Lemon or lime juice | ~2 |
Tips for Cutting Sugar in Cocktails
- Reduce syrup by a quarter or a third — most drinks still taste balanced with slightly less sweetness.
- Swap sweet & sour mix for fresh lemon or lime juice plus a small amount of simple syrup.
- Use diet tonic water or sparkling water for highballs like the Gin & Tonic or Vodka Soda.
- Try rich simple syrup (2:1 sugar to water) — a smaller volume delivers the same sweetness with less watery dilution.
- Flavored spirits and cream liqueurs add sugar even though they are alcoholic, so include them in the ingredient list.
Frequently Asked Questions
How accurate is this calculator? It relies on average sugar densities for common ingredients, so it is accurate enough for meal planning and general awareness. If you use a specific commercial product, check its nutrition label and enter the amount manually — the custom rows make that easy.
Why does my drink have more sugar than the preset? Presets represent straightforward versions of classic recipes. Real bars often use larger pours, additional syrups, or premade mixes that contain more sugar than the components listed here.
What is the daily value for added sugar? The FDA uses 50 g per day for a 2,000-calorie diet. The American Heart Association recommends stricter limits for most people: no more than 25 g per day for women and 36 g per day for men. See FDA added sugars guidance and AHA added sugars recommendations for details.
