Guacamole is a beloved dip, but if you're tracking carbs or managing blood sugar, you might wonder how much sugar it actually contains. This calculator estimates the total sugar in your homemade or store-bought guacamole based on the ingredients you use. It's perfect for keto dieters, diabetics, and anyone counting net carbs.
Simply enter the amounts of avocado, tomato, onion, lime juice, and optional add-ins like jalapeño or cilantro. The tool sums up the natural sugars from each ingredient and gives you a per-serving breakdown. You can also adjust the number of servings to see sugar per portion.
Whether you're meal prepping or just curious about your favorite recipe, this tool helps you make informed choices. Use it alongside our other nutrition calculators to track your daily intake accurately.

How to Use This Tool
Enter the amount of each ingredient in your guacamole recipe. You can switch between grams and ounces for solid ingredients, and between milliliters and tablespoons for lime juice. The calculator uses standard USDA nutrition data to estimate the natural sugar content. Adjust the number of servings to see the sugar per portion. Click "Calculate Sugar" to get your results, and use the quick-fill buttons to load common recipe variations.
Formula Explained
The total sugar is the sum of each ingredient's sugar contribution. For each ingredient, we multiply the weight (in grams) by its sugar density (grams of sugar per 100 grams). For lime juice, we use the density of lime juice (approximately 1.03 g/ml) to convert volume to weight, then apply the sugar percentage. The per-serving value is simply the total divided by the number of servings.
Reference values (per 100 g): Avocado 0.66 g, Tomato 2.6 g, Onion 4.24 g, Lime juice 0.4 g, Jalapeño 3.9 g, Cilantro 0.87 g. These are based on USDA FoodData Central.
Worked Examples
Example 1: Classic recipe: 100 g avocado, 50 g tomato, 20 g onion, 15 ml lime juice. Sugar: 0.66 + 1.3 + 0.85 + 0.06 = 2.87 g total. For 4 servings, that's 0.72 g per serving.
Example 2: Spicy version: 100 g avocado, 40 g tomato, 15 g onion, 20 ml lime, 15 g jalapeño, 5 g cilantro. Sugar: 0.66 + 1.04 + 0.64 + 0.08 + 0.59 + 0.04 = 3.05 g total. Per serving (4) = 0.76 g.
Tips & Best Practices
- Use ripe avocados for the best flavor; sugar content doesn't change much with ripeness.
- If you add other ingredients like mango or pineapple, their sugar will be higher — adjust accordingly.
- For keto diets, remember that sugar is part of total carbs. Guacamole is still low-carb because avocado is mostly fat and fiber.
- Store guacamole with lime juice to prevent browning; this also adds a tiny amount of sugar.
Factors Affecting Accuracy
Actual sugar content can vary by variety, ripeness, and growing conditions. The values used are averages from USDA data. If you use pre-packaged guacamole, check the label for added sugars, which can significantly increase the total. This calculator assumes no added sugar or sweeteners.
Frequently Asked Questions
Is guacamole high in sugar? No, a typical serving has less than 1 gram of sugar. The main sugars come from tomatoes and onions.
Can I use this for meal prep? Yes, just enter your batch ingredients and divide by the number of servings you plan to eat.
What about net carbs? Sugar is a carbohydrate, but avocado also contains fiber. For net carbs, subtract fiber from total carbs. You can use our net carbs calculator for a full breakdown.
Does lime juice add much sugar? Very little — about 0.4 g per 100 ml, so a tablespoon adds only ~0.06 g.
