How many calories is in a margarita on the rocks?

A margarita on the rocks is a classic tequila cocktail typically made with tequila, orange liqueur, and lime juice poured over ice. But how many calories are actually in one of these refreshing cocktails? Let’s take a closer look at the typical margarita ingredients and serving size to get an estimate of the calorie count.

Calories in Tequila

Tequila is the base spirit used in a margarita. An average 1.5 ounce (shot) serving of tequila contains around 105 calories. So for a standard margarita made with 2 ounces of tequila, that’s about 140 calories just from the tequila alone.

Tequila gets most of its calories from alcohol. Since alcohol contains 7 calories per gram, the more alcohol a spirit contains, the more calories it will have. Tequila typically contains 40% alcohol by volume (80 proof).

Calories in Orange Liqueur

The orange liqueur is the ingredient that gives a margarita its signature orange flavor. Popular orange liqueurs used include triple sec and Cointreau. A 1.5 ounce serving of triple sec contains about 105 calories, similar to tequila.

Orange liqueurs get their calorie content from both alcohol and added sugar. The sweet flavor comes from added sugars or syrups. So orange liqueurs contain more calories ounce-for-ounce than straight tequila.

Calories in Lime Juice

Freshly squeezed lime juice provides the tart, citrusy flavor that balances out the sweetness of the orange liqueur. Lime juice is very low in calories, with only about 20 calories in 3 tablespoons (1.5 ounces). So the lime juice adds minimal calories to a margarita.

Calories in Simple Syrup

Some margarita recipes also include simple syrup, which is equal parts sugar and water dissolved together. Simple syrup helps sweeten and soften the acidity of the lime juice. A 1 ounce serving of simple syrup contains about 105 calories, again mainly from the sugar content.

So if a margarita contains 1 ounce of simple syrup, that tacks on another 105 calories to the total count.

Calories in Ice

Margaritas are shaken or stirred with ice and then poured over fresh ice to be served on the rocks. The ice itself is calorie-free, so it doesn’t impact the calorie content.

However, drinking a margarita over ice will dilute the cocktail slightly compared to drinking it straight up. So the calories get “spread out” over a larger volume, reducing the calories per sip.

Standard Margarita Calories

A standard margarita recipe contains 2 ounces tequila, 1 ounce orange liqueur, and 1 ounce fresh lime juice. This works out to:

  • Tequila: 140 calories
  • Orange liqueur: 105 calories
  • Lime juice: 20 calories
  • Total: 265 calories

So in total, a standard 4 ounce margarita made with blanco tequila, triple sec, and fresh lime juice contains about 265 calories.

Margarita on the Rocks vs Straight Up

Does serving a margarita on the rocks change the calorie content compared to drinking it straight up without ice? Generally, no:

  • On the rocks – The ice dilutes the margarita slightly, but the total volume of liquid and calories remains roughly the same.
  • Straight up – No dilution from ice, so slightly more concentrated calories per sip. But the total calorie count is still 265 for a standard 4 ounce margarita.

So the on the rocks vs straight up preparation doesn’t significantly alter the total calorie content.

Factors that Increase Margarita Calories

While a standard margarita clocks in at 265 calories, the count can go up depending on the recipe. Factors that increase the calories in a margarita include:

  • Bigger glass size – A 6-8 ounce margarita glass with a bigger cocktail obviously has more calories.
  • More ingredients – Additional liqueurs like Cointreau or simple syrup boost calories.
  • Sugary drink mixers – Margarita mixes add lots of sugar and calories.
  • Flavored tequila – Flavored tequilas have added sugars.

To keep the calorie count lower, opt for a 4 ounce cocktail made with 100% agave blanco tequila and without sugary bottled mixes.

Low Calorie Margarita Options

Here are some easy tips for lightening up your margarita:

  • Use 100% agave tequila instead of a lower quality tequila with added sugars.
  • Go easy on the orange liqueur – try 3/4 ounce instead of a full ounce.
  • Skip the simple syrup altogether or reduce the amount.
  • Squeeze in a little extra lime juice to cut down the sweetness.
  • Add sparkling water for a spritzy, lower-calorie margarita.
  • Garnish with fresh fruit like lime, orange, or berries instead of salt.

With a few minor tweaks, you can still enjoy a flavorful margarita without all the extra calories weighing it down.

Skinnier Margarita Recipe

Here is a slimmed-down margarita recipe that doesn’t compromise on flavor:


  • 2 ounces blanco tequila
  • 1/2 ounce Cointreau
  • 1 1/2 ounces fresh lime juice
  • 1/2 ounce agave nectar
  • Lime wedge for garnish
  • Ice


  1. In a cocktail shaker, combine tequila, Cointreau, lime juice, and agave nectar with ice.
  2. Shake vigorously until well chilled.
  3. Strain into a rocks glass filled with fresh ice.
  4. Garnish with a lime wedge.

This light margarita has just around 200 calories – 25% less than a standard recipe. Yet it doesn’t compromise on flavor thanks to fresh citrus juice and good quality ingredients. Sip guilt-free and enjoy!

Calories in Margarita Variations

Margaritas are highly adaptable cocktails with many possible variations. Here are the approximate calories for some popular margarita spins:

Margarita Variation Calorie Count
Fruit margarita 250-300 calories
Skinny margarita 150-200 calories
Frozen margarita 300-500 calories
Margarita with soda 220 calories
Margarita on the rocks 265 calories
Blended strawberry margarita 350 calories
Cadillac margarita 300 calories
Skinny margarita 150-200 calories

In general, fruit purees and frozen blends pack on extra calories compared to a classic on the rocks margarita. Watch out for premixed, bottled margarita which can weigh in at 200 calories per serving or more.

Tips for Light Margaritas

Here are some final tips for keeping your margarita light:

  • Use 100% agave tequila for fewer calories than a mixto tequila.
  • Go easy on high-calorie orange liqueurs – 1/2 to 3/4 ounce is plenty.
  • Skip the simple syrup and use agave nectar instead if you need a sweetener.
  • Use fresh lime juice rather than sweet & sour mix.
  • Add some sparkling water to dilute and lighten the cocktail.
  • Garnish with fresh fruit instead of a sugary rim.
  • Enjoy on ice to naturally dilute the drink as you sip.

With some simple substitutions and smart tweaks, you can definitely still enjoy a margarita without sabotaging your healthy eating goals. Just be mindful of portion sizes. Salud!


A standard 4 ounce margarita on the rocks made with blanco tequila, orange liqueur, and fresh lime juice clocks in around 265 calories.
