How Many Calories Are In Mayonnaise? | Quick Facts Guide

Calories In Mayonnaise: By Serving Size

Mayonnaise is an oil-in-water emulsion, so most of its energy comes from fat. A standard label serving is 1 tablespoon (14–15 g). Regular mayo lands near 100 calories per tablespoon because it carries about 11–12 g fat. Light versions trim oil and fall around 35–60 calories. Fat-free “mayo-style” dressings replace oil with water and starches, averaging 10–15 calories per tablespoon. The table below gives quick reference points you can use at the counter.

Serving	Regular Mayo (kcal)	Light/Fat-Free (kcal)
1 teaspoon (5 g)	~30–35	~5–12
1 tablespoon (14–15 g)	~94–100	~35–60 (light), ~13 (fat-free)
2 tablespoons	~188–200	~70–120
100 grams	~680	~150–330

Those ranges reflect different formulas and brands. Independent nutrient databases list regular mayonnaise between 94 and 110 calories per tablespoon, and branded “real” mayo labels commonly print 100 calories per tablespoon. Government datasets also provide entries for regular, light, and fat-free variants so you can match your exact jar.

What Drives The Calories In Mayo

Oil content sets the number. Classic mayo emulsifies neutral oil with egg, acid, and salt. A tablespoon delivers roughly 11–12 g fat—about 100 calories—because fat supplies 9 calories per gram. Light mayo cuts oil and adds water and gums for body, so calories fall; fat-free swaps almost all the oil for water, starches, or fiber.

Regular Vs. Light Vs. Fat-Free

Regular sits around 94–110 calories per tablespoon. Light typically runs 35–60. Fat-free drops near 10–15. Brands vary, so it pays to read your label once and stick to a spoon that fits your plan.

Oil Type And Egg Content

Most shelf mayo uses soybean, canola, or similar oils. Olive-oil mayo is usually a blend, so calories per spoon stay similar because total fat remains near 11–12 g. Egg-less or vegan mayo swaps plant thickeners for egg yolk; many versions cluster near light mayo ranges unless labeled fat-free.

Portion Math You Can Use

Spreads add up fast. Two big spoonfuls on a sandwich can push 200 calories with regular mayo. Switching to light mayo and using the same smear slides closer to 70–120 calories. For salad-style recipes, use a measured cup, then scale the batch to hit the numbers you want.

Once you’ve set your daily calorie needs, treat mayo like any other concentrated fat: measure once, learn your typical layer, and budget it in.

How Many Calories In Mayonnaise Per Spoon?

Here are label-style snapshots pulled from well-cited nutrient databases and brand pages. These figures help you eyeball portions without a calculator.

• Regular mayo: 94–100 kcal per tablespoon; ~11–12 g fat; ~0 g carbs; ~0 g protein.
• Light mayo: 35–60 kcal per tablespoon; ~3.5–6 g fat; ~0–1 g carbs.
• Fat-free mayo-style dressing: ~13 kcal per tablespoon; ~0.4 g fat; ~2–2.5 g carbs.
• Per 100 g regular mayo: ~680 kcal; ~75 g fat.

For source-level details on those bands, see a mayonnaise entry in a reputable nutrition database and the U.S. government’s nutrient system. You can also check a brand page to confirm the exact label you’re using.

Smart Ways To Trim Mayo Calories

Swap, Split, Or Stretch

Mix half regular mayo with thick plain yogurt to cut calories and keep body. Light mayo plus mustard or extra lemon gives more punch per spoon. For potato or slaw dressings, thin the sauce and toss thoroughly so less clings to the bowl.

Measure And Pick The Right Spoon

A flat tablespoon is smaller than a heaping knife scoop. Level it when you want precision. For sandwiches, two teaspoons per slice usually cover the bread edge-to-edge without puddles.

Choose Lower-Calorie Styles

Light mayo is the easiest win for spreads. Fat-free dressings can shine in tuna or chicken salads where other ingredients bring texture and bite.

Homemade Mayo: What Changes?

Many home recipes use 1 cup (about 240 g) of oil per batch that yields roughly 1½ cups. That cup of oil alone supplies about 1,920 calories. Spread across 24 tablespoons of finished mayo, you’re near 80–90 calories per tablespoon before the egg and acid add a little more. Use more oil or whip less air and you’ll land back around ~100 calories per tablespoon.

Ways To Lighten A Homemade Batch

• Blend in more water with high shear to reduce oil per spoon.
• Swap part of the oil for skyr or thick yogurt; keep salt and acid bright.
• Lean on mustard, garlic, or hot sauce so you need less overall.

Nutrition Snapshot Beyond Calories

Regular mayo contributes vitamin K from plant oils and a bit of vitamin E. Sodium varies by brand. Carbs stay near zero in regular versions and rise slightly in light or fat-free recipes where starches replace oil. Cholesterol sits in single-digit milligrams per tablespoon because egg yolk is diluted by a large amount of oil.

Allergies And Handling

Commercial mayo is made with pasteurized ingredients and enough acid to discourage common pathogens. Egg-allergic eaters can pick vegan options. Keep jars chilled after opening and use clean utensils to avoid contamination.

Popular Mayo Types And Calories

Type	Per Tbsp	Notes
Regular “real” mayo	~94–100 kcal	~11–12 g fat; carbs ~0 g
Olive-oil mayo	~90–100 kcal	Usually oil blends; calories similar
Avocado-oil mayo	~90–100 kcal	Fat profile shifts; calories similar
Light mayo	~35–60 kcal	~3.5–6 g fat; water/gums add texture
Fat-free mayo-style	~13 kcal	~0.4 g fat; ~2–2.5 g carbs
Vegan mayo	~60–100 kcal	Ranges by oil and thickeners

How To Read Your Jar

Serving Size

Most labels list 1 tablespoon. Some use 15 g instead of 14 g, which can nudge the calorie printout. When comparing brands, match serving mass first so you’re not mixing apples and oranges.

Calories From Fat

Multiply grams of fat by 9 to verify the math. If a label says 12 g fat, that’s ~108 calories just from fat, plus any minor calories from carbs or protein.

Ingredient Signals

Terms like “light,” “reduced fat,” and “fat-free” follow regulatory definitions. Light mayo generally has about half the fat of regular. Fat-free relies on water and thickeners and often leans sweeter or tangier to feel balanced.

Practical Uses That Keep Flavor High

Sandwiches

Spread edge-to-edge with a thin coat so each bite hits. Add crunchy lettuce or pickles for texture, which lets you use less for the same satisfaction.

Salads

In tuna or chicken salad, swap a third of the mayo with Greek yogurt and a squeeze of lemon. Light mayo works well here and stays creamy.

Dips And Dressings

Whisk light mayo with yogurt, lemon, and garlic for a quick dip. For slaw, thin the dressing slightly and toss well so it coats every shred without clumping.

Credible Numbers You Can Trust

You’ll see a consistent picture across independent databases and official datasets: regular mayo sits near 100 calories per tablespoon; light mayo often hits the mid-30s; fat-free drops near a dozen. That’s why portion size and style are the two levers that change your plate the most.
