How Many Carbs Are In A McDonald's Iced Coffee?

A small sweetened McDonald’s iced coffee has about 25g of carbs, black iced coffee sits near 0–1g, and a large sweetened iced coffee reaches about 47g.

Here’s the quick answer most people want before ordering. Carbs in McDonald’s iced coffee come almost entirely from the liquid sugar and any flavored syrup. Brewed coffee itself contributes essentially none. If you want the fewest carbs, order it black over ice. If you want a sweet sip, choose a size and flavor knowing the ranges below.

Carbs In A McDonald’s Iced Coffee By Size And Flavor

McDonald’s lists nutrition for each drink on its menu pages. Pulling from those entries, plus the black-iced-coffee listing, here’s a simple table you can scan before you hit the speaker box.

Drink (U.S. Menu)	Size	Total Carbs
Iced Coffee, Black	Medium	1g
Iced Coffee, Black	Small	≈0–1g (estimated from brewed coffee data)
Iced Coffee, Black	Large	≈0–1g (estimated from brewed coffee data)
Iced Coffee (Liquid Sugar + Cream)	Small	25g
Iced Coffee (Liquid Sugar + Cream)	Medium	32g
Iced Coffee (Liquid Sugar + Cream)	Large	47g
French Vanilla Iced Coffee	Small	25g
Caramel Iced Coffee	Small	23g
Sugar-Free French Vanilla Iced Coffee	Small	9g

Why the spread? The brew itself is near-zero carb; the liquid sugar and flavored syrups add the grams. If you order black, you’re essentially at zero. If you keep the sweetener and scale up to a large, carbs climb fast.

Featured Numbers Straight From The Menu

McDonald’s product pages show the carb counts you see above: small iced coffee at about 25g of carbs, large iced coffee at about 47g, and the medium black iced coffee at about 1g. Those pages also call out the ingredients, including liquid sugar and cream. If you need a reference that brewed coffee itself is virtually carb-free, medical and nutrition listings for plain brewed coffee show 0g carbohydrate per cup. Links are in the body below.

What Counts As “Iced Coffee” Here

This page is about McCafé iced coffee—brewed coffee poured over ice, with cream and optional flavor syrups. That’s different from espresso drinks (like iced latte) and from blended frappes. If you’re asking “how many carbs are in a mcdonald’s iced coffee?” you’re almost always talking about this brewed-coffee base with or without sweetener.

How Flavor Choices Change The Carb Load

Black Over Ice

Order “black iced coffee” (no liquid sugar, no cream) and you’re near 0–1g. That aligns with brewed-coffee nutrient data, which lists zero carbohydrate for an 8-ounce cup.

Regular Sweetened (House Liquid Sugar + Cream)

This is the default sweet order in many markets. A small sits around 25g carbs. Moving to medium and large pushes carbs up to the low 30s and the high 40s.

Flavored Syrups

French Vanilla and Caramel smalls land near the same ballpark as a small regular sweetened. Sugar-free French Vanilla drops that number into single digits for the small size. If your location lets you adjust pumps, fewer pumps mean fewer carbs.

Ordering Tips To Hit Your Target

Say The Carbs Out Loud

If you’re counting grams, say it when you order: “black iced coffee,” “no liquid sugar,” or “sugar-free vanilla, just a splash of cream.” Staff hears these requests all day. Keep it crisp and they’ll build it that way.

Pick The Sweetener Strategy

Skip liquid sugar: This takes most of the carbs off the table. Sweeten at home if you need control.
Ask for sugar-free vanilla: When available, it trims carbs compared with the regular sweetened version.
Go lighter on pumps: If your store allows it, “one pump” or “half syrup” is an easy cut.

Mind The Size

Size multiplies syrup. If you like it sweet, sticking with a small keeps the count sane. If you need a large cup in hand, black is the simplest path.

Ingredient Notes That Explain The Numbers

McDonald’s iced coffee uses brewed 100% Arabica coffee over ice. Carbs show up when you add the house liquid sugar and flavor syrups. Cream contributes minimal carbohydrate compared with the sweetener. That’s why a black iced coffee sits near zero while the same cup with liquid sugar jumps into double digits.

Why Black Is Basically Zero

Plain brewed coffee contains 0g of carbohydrate per cup in standard nutrition listings. That’s why “how many carbs are in a mcdonald’s iced coffee?” often has two answers: near-zero if it’s black, or a higher number once sweetener enters the cup.

Quick Ways To Reduce Carbs Without Losing The Iced Coffee Feel

Start With Black, Add A Dash

Order black, then add a modest splash of cream at the condiment area if your restaurant offers it. You keep carbs low while softening the edge.

Choose Sugar-Free Syrup

When available, sugar-free French vanilla drops the carb count. The small-size listing lands in single digits, which is a big swing for anyone tracking numbers.

Own The Sweetness Level

Not every store will change pump counts, but many will. Asking for one pump or half syrup trims grams without turning your drink into plain iced coffee.

Customization And Carb Impact (Estimates)

Change	What It Does	Carb Impact
Order Black (No Liquid Sugar, No Cream)	Removes sweetener entirely	Drops to ≈0–1g
Ask For “No Liquid Sugar”	Keeps coffee + ice + cream only	Removes most carbs in sweetened drink
Switch To Sugar-Free Vanilla	Replaces sugary syrup	Small lands near 9g
Downsize Cup	Less syrup and cream	Small < Medium < Large
Fewer Pumps (If Allowed)	Less sweetener per cup	Linear cut per pump
Add Sweetener Yourself	Use packets or drops you track	Control exact grams

Practical Orders For Different Carb Goals

Zero-To-One-Gram Crowd

Order “black iced coffee.” If you want a touch of cream, keep it to a splash. That keeps the drink crisp and the carb number tiny.

Single-Digit Target

Go small with sugar-free French vanilla. It’s sweet, it’s iced, and the listed carb number stays in single digits.

Classic Sweet Cup With Boundaries

Choose a small regular sweetened iced coffee, or ask for fewer pumps in a medium. You’ll get the familiar taste while keeping the number under control.

Sourcing, Variability, And A Quick Method Note

Numbers in the first table come from McDonald’s U.S. product pages for iced coffee and flavored variants, plus the black iced coffee entry. Plain brewed-coffee carb data is pulled from a clinical nutrition listing that shows 0g carbohydrate for brewed coffee. Menus can change by location and season; stores may pour syrup differently; and nutrition pages sometimes update. If you’re tracking daily totals, check the in-app nutrition calculator for your nearest store before you order.
