Mayonnaise is a staple condiment in sandwiches, salads, and dips, but its calorie and fat content can vary widely depending on the brand and type. Our Mayonnaise Nutrition Calculator helps you quickly estimate the calories, total fat, saturated fat, cholesterol, sodium, and carbohydrates in any serving size of regular, light, or fat-free mayonnaise.
Simply enter the amount of mayonnaise you plan to use, select the type, and choose your preferred unit (tablespoon, teaspoon, cup, or grams). The calculator instantly provides a full nutrition breakdown, including a per-serving summary and a step-by-step calculation breakdown so you can see exactly how the numbers are derived.
Whether you're tracking macros, managing sodium intake, or just curious about the nutritional impact of your favorite condiment, this tool is designed for home cooks, dietitians, and health-conscious eaters alike.

How to Use This Tool
Using the Mayonnaise Nutrition Calculator is straightforward. Start by entering the amount of mayonnaise you plan to use in the numeric field. Then select the unit from the dropdown — options include tablespoons, teaspoons, cups, and grams. Next, choose the type of mayonnaise: regular (full-fat), light (reduced-fat), or fat-free. Click the Calculate button to see the full nutrition breakdown. The results show calories, total fat, saturated fat, cholesterol, sodium, carbohydrates, and protein for your specified serving.
You can also use the quick-fill preset buttons to instantly populate common serving sizes like 1 tablespoon or 100 grams. This is especially handy when you're following a recipe that lists ingredients in grams or when you're estimating a sandwich spread.
How It Works
The calculator uses standard nutrition data for mayonnaise per 100 grams, based on USDA FoodData Central values. For regular mayonnaise, the per-100g values are approximately 680 kcal, 75 g fat, 11.7 g saturated fat, 42 mg cholesterol, 635 mg sodium, 0.6 g carbohydrates, and 0.9 g protein. Light mayonnaise has about 334 kcal, 33.3 g fat, 5.1 g saturated fat, 42 mg cholesterol, 911 mg sodium, 11.7 g carbs, and 0.9 g protein. Fat-free mayonnaise contains roughly 106 kcal, 0.3 g fat, 0 g saturated fat, 0 mg cholesterol, 911 mg sodium, 23.9 g carbs, and 0.3 g protein.
To convert your input to grams, the calculator uses these conversions: 1 tablespoon = 13.8 g, 1 teaspoon = 4.6 g, 1 cup = 220 g, and 1 gram = 1 g. Once the total grams are determined, each nutrient is scaled proportionally. For example, if you enter 2 tablespoons of regular mayonnaise, that's 27.6 g, which is 27.6% of 100 g, so each nutrient value is multiplied by 0.276.
Worked Examples
Example 1: Sandwich Spread
You use 1 tablespoon (13.8 g) of regular mayonnaise on your sandwich. The calculator computes: 13.8 g / 100 g = 0.138. Calories = 680 × 0.138 = 93.8 kcal. Total fat = 75 × 0.138 = 10.4 g. Saturated fat = 11.7 × 0.138 = 1.6 g. Cholesterol = 42 × 0.138 = 5.8 mg. Sodium = 635 × 0.138 = 87.6 mg. Carbohydrates = 0.6 × 0.138 = 0.1 g. Protein = 0.9 × 0.138 = 0.1 g.
Example 2: Salad Dressing
You make a coleslaw with 3 tablespoons (41.4 g) of light mayonnaise. The factor is 0.414. Calories = 334 × 0.414 = 138.3 kcal. Fat = 33.3 × 0.414 = 13.8 g. Saturated fat = 5.1 × 0.414 = 2.1 g. Cholesterol = 42 × 0.414 = 17.4 mg. Sodium = 911 × 0.414 = 377.2 mg. Carbs = 11.7 × 0.414 = 4.8 g. Protein = 0.9 × 0.414 = 0.4 g.
Tips & Best Practices
- Check the label: Different brands can vary significantly in fat and sodium content. Always verify the nutrition facts on your specific product for the most accurate tracking.
- Use a kitchen scale: For precise tracking, weigh your mayonnaise in grams rather than relying on volume measurements, especially for larger amounts.
- Mind the serving size: A typical serving is 1 tablespoon, but many recipes call for more. This calculator helps you see the cumulative impact.
- Consider alternatives: If you're watching calories, light or fat-free versions can cut calories dramatically, but they often contain more sodium and added sugars.
Factors Affecting Accuracy
The nutrition values used are averages from the USDA FoodData Central database. Actual values can differ based on the brand, recipe, and specific ingredients (e.g., eggs, oil type, vinegar). Some brands may use olive oil or avocado oil, which can alter the fat profile. Additionally, homemade mayonnaise may have different proportions of oil and egg, leading to higher or lower calorie counts. For medical or dietary planning, always consult the product label or a registered dietitian.
Frequently Asked Questions
Is mayonnaise high in calories?
Yes, regular mayonnaise is calorie-dense because it's primarily oil. One tablespoon contains about 94 calories. Light versions have about half that, and fat-free versions have about 15 calories per tablespoon.
Does mayonnaise contain carbohydrates?
Regular mayonnaise has very few carbs (less than 1 g per tablespoon). Light and fat-free versions often contain added sugar or starch to mimic texture, so they have more carbs — up to 3-4 g per tablespoon for fat-free.
Can I use this calculator for homemade mayonnaise?
Yes, but the results will be approximate. Homemade mayonnaise typically has similar fat content to commercial regular mayonnaise, but the exact values depend on your recipe. For a more precise estimate, calculate based on the oil and egg yolks used.
Why does light mayonnaise have more sodium?
To compensate for reduced fat, manufacturers often add more salt and other flavor enhancers. This is why light and fat-free versions can have significantly higher sodium per serving.
