Quick Summary
Calorie Count: 1 level tablespoon (14g) of regular mayo contains 94 to 95 calories and 10 to 10.5g of fat.
Light Alternatives: Light mayo options cut calories down to 35–50 calories per tablespoon.
Keto Friendly: Mayo has virtually zero carbs (0.1g/tbsp) and a GI of 0, making it great for keto—just mind your portion sizes!
Unsaturated Fats: Regular mayo made from plant oils is rich in heart-healthy unsaturated fats (PUFAs and MUFAs).
Easy Tracking: Don't let sneaky condiment calories throw off your goals—use VoCal for fast, voice-activated logging!
Ah, mayonnaise. Whether it is giving your turkey sandwich that perfect creamy touch, holding together a classic potato salad, or serving as the base for a mouthwatering dipping sauce, mayo is an undisputed kitchen favorite. But if you have ever squeezed or dolloped a bit extra onto your plate, you have probably wondered about total mayo calories and how they fit into your daily routine.
When you look at mayo calorie by tablespoon, the numbers can be surprisingly big for such a small serving! Because mayo is primarily an emulsion of oil and egg yolks, even a small portion carries a dense calorie count. Let’s dive into the complete nutritional facts, compare regular vs. light varieties, see how mayo works on keto or low-carb diets, and learn how to track it effortlessly.
Track Your Spreads Effortlessly with VoCal
The Eyeball Trap: Unmeasured spreads are one of the biggest reasons calories sneak up on us. A "heavy tablespoon" spread with a butter knife can easily turn into two or three tablespoons without you realizing it.
The Smart Solution: With VoCal, you don't have to search through complex databases or guess standard weights. Just speak naturally into your phone—say "Added 1 level tablespoon of Hellmann's light mayo to my wrap"—and let AI take care of the math instantly!
How Many Calories Are in 1 Tbsp of Mayo?

Standard regular mayonnaise is a classic emulsion of plant oil, egg yolks, vinegar or lemon juice, and a pinch of salt. Because oil is pure fat, standard mayo is a calorie-dense condiment.
A standard 1-tablespoon serving (about 14 grams) of regular salted mayo contains 94 to 95 calories. Nearly 99% of those calories come directly from fat!
If you are keeping an eye on your calorie budget, commercial brands also offer lighter alternatives that swap out some of the oil for water and modified food starch.

Here is a handy comparison breakdown of standard varieties per 1-tablespoon serving:
Nutrient | Regular Mayo (1 Tbsp / 14g) | Light Mayo (1 Tbsp / 15g) | Low-Calorie Mayo (1 Tbsp / 14g) |
Calories (kcal) | 94 – 95 | 35 – 50 | 32 |
Total Fat (g) | 10.0 – 10.5 | 3.0 – 5.0 | 2.7 |
Saturated Fat (g) | 1.6 – 2.0 | 0.5 – 1.0 | 0.46 |
Monounsaturated Fat (g) | 2.0 | 1.0 | 0.63 |
Polyunsaturated Fat (g) | 6.0 | 1.5 – 2.0 | 1.26 |
Sodium (mg) | 88 – 89 | 95 – 124 | 15.4 |
Total Carbs (g) | 0.1 | 1.0 – 2.2 | 2.2 |
Protein (g) | 0.1 | 0.04 – 0.1 | 0.04 |

Understanding the Fats in Mayonnaise
Not all fats are created equal! While mayonnaise is high in fat, the type of fat depends heavily on the oil used to make it.
Most standard off-the-shelf mayos are made with soybean or canola oil. As a result, the majority of the fat content consists of heart-healthy polyunsaturated fats (6.0 grams per tbsp) and monounsaturated fats (2.0 grams per tbsp). It also provides about 1.0 gram of Alpha-Linolenic Acid (ALA), an essential omega-3 fatty acid.
Saturated Fat and Heart Health
Regular mayo contains around 1.6 to 2.0 grams of saturated fat per tablespoon. The American Heart Association (AHA) recommends limiting saturated fat to less than 6% of your daily calories (about 13 grams per day for a 2,000-calorie diet). While a single tablespoon fits easily within that limit, eating multiple unmeasured scoops can add up fast.
Smart Swap Idea
Choose Heart-Healthy Oils: Look for mayo made with olive oil, avocado oil, or high-oleic canola oil to get more monounsaturated fats.
Go Light or Mix: Switch to light mayo to cut calories by over 50%, or mix regular mayo 1:1 with non-fat plain Greek yogurt for extra protein and a lighter creaminess!
Mayo on Low-Carb and Keto Diets: Friend or Foe?
If you are on a ketogenic or low-carb diet, mayo might feel like a dream come true! With virtually zero carbohydrates (0.1 grams per tablespoon) and a Glycemic Index (GI) of 0, regular mayo won't spike your blood sugar or trigger insulin surges.
However, even on keto, energy balance still matters. While low-carb diets help suppress appetite and eliminate excess water weight early on, overdoing energy-dense foods can stall body fat reduction.
Water Weight vs. Fat Loss
The First Weeks: Restricting carbs leads to rapid drops in glycogen stores and water weight.
Long-Term Progress: Losing actual body fat still requires a sensible calorie balance. Keeping tabs on mayo calories tablespoon sizes ensures you stay on track without guessing!
Mayo vs. Other Popular Condiments
How does mayo compare to the rest of the sauce squeeze-bottles in your fridge? Here is how a 100-gram serving of mayonnaise stacks up against ranch, ketchup, and mustard:
Condiment (per 100g) | Calories | Total Fat (g) | Total Carbs (g) | Sodium (mg) |
Regular Mayonnaise | 680 | 75.0 | 0.6 | 635 |
Ranch Dressing | 430 | 45.0 | 6.0 | 1030 |
Tomato Ketchup | 101 | 0.1 | 25.0 | 907 |
Yellow Mustard | 66 | 4.0 | 5.0 | 1135 |
Data derived from USDA comparative nutrition standards.
As you can see, mayo is the most calorie- and fat-dense condiment of the bunch. On the flip side, it contains almost no sugar or carbohydrates compared to ketchup, and less sodium than mustard or ranch.
The "Eyeball Problem": How Heavy Spreads Add Up

Let’s be honest: almost nobody uses a measuring spoon when spreading mayo on a sandwich! A typical "heaping knife-spread" or "generous squeeze" is often closer to 2 or 3 tablespoons (25–40 grams) rather than a single level tablespoon (14 grams).
That small misestimation can add an extra 100 to 200 uncounted calories to your meal! Over a week, those extra dollops can add up to over 1,000 unrecorded calories.
