Guacamole is a potassium-rich dip made primarily from avocados, which are famously high in this essential mineral. Potassium supports heart function, muscle contractions, and fluid balance, making it a key nutrient for athletes, people managing blood pressure, and anyone following a balanced diet.
This calculator estimates the potassium content in your guacamole based on the amount of avocado and optional add-ins like lime juice, onion, tomato, and salt. Whether you’re tracking your daily potassium intake for health reasons or simply curious about the nutritional profile of your homemade guac, this tool provides a quick, reliable estimate. Just enter your ingredients and serving size to get started.

How to Use This Tool
Enter the number of avocados and select their size (small ~100g, medium ~150g, large ~200g). Then add the amounts of lime juice, onion, tomato, and salt you typically use. Finally, specify your serving size in tablespoons. Click "Calculate Potassium" to see the potassium content per serving and for the entire batch. Use the Reset button to clear all fields and start over.
How It Works
The calculator estimates potassium based on standard USDA nutritional data. Avocados are the primary source, contributing about 485 mg of potassium per 100 grams. Lime juice adds ~10 mg per tablespoon, onion ~10 mg per tablespoon, and tomato ~5 mg per tablespoon. Salt contains negligible potassium. The total batch volume is approximated using avocado density (~0.67 g/ml) and the volume of other ingredients (1 tbsp = 15 ml). The potassium per serving is then calculated proportionally.
Example Calculation
Scenario: You make guacamole with 2 medium avocados, 2 tbsp lime juice, 3 tbsp onion, 3 tbsp tomato, and 0.25 tsp salt. Your serving size is 4 tbsp.
Calculation: Avocado weight = 2 × 150g = 300g. Potassium from avocado = (300/100) × 485 = 1455 mg. Lime: 2 × 10 = 20 mg. Onion: 3 × 10 = 30 mg. Tomato: 3 × 5 = 15 mg. Total potassium = 1520 mg. Batch volume = (300 × 0.67) + (2+3+3) × 15 = 201 + 120 = 321 ml. Potassium per serving = (1520 / 321) × (4 × 15) ≈ 284 mg.
Tips for Accuracy
- Use a kitchen scale to weigh your avocado for the most accurate result. The size presets are averages.
- Be consistent with your measuring spoons — level tablespoons are standard.
- If you add other ingredients like cilantro, jalapeño, or garlic, their potassium contribution is minimal but can be added manually.
- For those tracking potassium for medical reasons (e.g., kidney disease), always consult a dietitian and use verified nutrition data.
Frequently Asked Questions
Is guacamole high in potassium? Yes, avocados are one of the best fruit sources of potassium. A typical serving of guacamole (4 tbsp) can provide 250–350 mg of potassium, which is about 5–7% of the daily recommended intake (4700 mg for adults).
Can I use this calculator for store-bought guacamole? This calculator is designed for homemade guacamole. Store-bought versions may have added ingredients (e.g., preservatives, extra lime juice) that alter the potassium content. Check the nutrition label for the most accurate values.
How does potassium in guacamole compare to other foods? A medium banana has about 422 mg of potassium. A 4-tbsp serving of guacamole provides roughly two-thirds of that amount, making it a potassium-dense choice. For comparison, see our blueberry potassium calculator or salsa potassium calculator.
