They look similar — two tall cups of cold brown liquid with ice. But an iced latte and an iced coffee are made completely differently, taste noticeably different, cost different amounts, and even have different amounts of caffeine. Understanding the difference is the first step to ordering the right cold drink for you.
How Each Is Made
The fundamental difference: espresso vs. brewed coffee. Espresso is made by forcing hot water through finely-ground coffee at high pressure — producing a small, concentrated shot (about 1 oz per shot). Brewed coffee is made by dripping hot water through coarser grounds — producing a larger, less concentrated liquid (8–16+ oz). An iced latte combines those small, intense shots with a large amount of cold milk. An iced coffee is mostly brewed coffee with just a splash of milk (if any).
This is why they taste so different. An iced latte is creamy, smooth, and mild — the milk dilutes and softens the espresso. An iced coffee is stronger, more traditionally "coffee-flavored," and less creamy — the coffee is the dominant flavor, not the milk.
The Full Comparison
| Attribute | Iced Latte | Iced Coffee | Winner |
|---|---|---|---|
| Coffee base | Espresso (1–3 shots) | Brewed coffee | Different |
| Milk amount | Heavy (~10–14 oz in a Grande) | Light splash (~1–2 oz) | Latte if creamy |
| Caffeine (Starbucks Grande) | 150mg (2 shots) | 165mg | Iced Coffee |
| Calories (2% milk, unsweetened) | ~130 | ~80 (splash of milk) | Iced Coffee |
| Price (Starbucks Grande) | ~$5.25 | ~$3.45 | Iced Coffee |
| Sweetness (default) | Unsweetened | Sweetened (Classic Syrup at Starbucks) | Latte if you avoid sugar |
| Flavor profile | Creamy, mild, smooth | Strong, bold, coffee-forward | Preference |
| Customization | Milk choices, syrups, cold foam | Milk, syrups, cold foam | Equal |
| Best for beginners | Yes — milk softens the coffee | No — strong coffee flavor | Latte |
Caffeine: The Counter-Intuitive Truth
Most people assume the latte has more caffeine because it contains espresso. The opposite is true at most chains:
| Drink (Grande) | Starbucks | Dunkin' |
|---|---|---|
| Iced Latte | 150mg (2 shots) | ~118mg (2 shots) |
| Iced Coffee | 165mg | ~297mg |
| Cold Brew | 205mg | ~260mg |
Brewed coffee extracts more total caffeine because there's simply more liquid coffee in the cup. An espresso shot has ~75mg in 1 ounce (extremely concentrated), but a Grande Iced Latte only has 2 shots. A Grande Iced Coffee has 16 ounces of brewed coffee, each ounce contributing ~10mg. Volume wins.

The Price Gap Is Huge
At Starbucks, the price difference between a Grande Iced Coffee ($3.45) and a Grande Iced Latte ($5.25) is $1.80 — a 52% premium. Over a 5-day-per-week habit, that's $36 per month or $432 per year. The iced coffee actually gives you more caffeine for less money.
The price gap exists because espresso requires an expensive machine, a trained barista to pull shots, and uses more milk. Brewed coffee drips passively into a pot. If you're budget-conscious, iced coffee is the smarter daily choice — save the latte for when you specifically want the creamy, milk-forward experience. See our budget guide for more cost-saving strategies.
What About Cold Brew?
Cold brew is a third option that sits between the two — and it's increasingly replacing both:
| Attribute | Iced Coffee | Cold Brew | Iced Latte |
|---|---|---|---|
| How it's made | Hot-brewed, then iced | Cold-steeped 12–24 hours | Espresso + cold milk |
| Acidity | Higher (hot brewing extracts acids) | 67% less acid than iced coffee | Medium (espresso-level) |
| Taste | Bright, sharp, traditional | Smooth, chocolatey, mellow | Creamy, mild, milk-forward |
| Caffeine (Grande) | 165mg | 205mg | 150mg |
| Price (Grande) | ~$3.45 | ~$4.25 | ~$5.25 |
Cold brew has become the default for many people because it's smoother and less bitter than iced coffee, cheaper than a latte, and has more caffeine than both. It's the best of both worlds. For the full breakdown, see our iced coffee vs cold brew comparison.
How Each Chain Makes Them Differently
At Starbucks
Iced Coffee: Brewed double-strength with their Pike Place blend, then cooled. Sweetened with Classic Syrup by default — say "unsweetened" to skip it and save ~80 calories. Available up to Trenta (30 oz). The cheapest caffeinated drink at Starbucks.
Iced Latte: 2 espresso shots (standard Signature roast) poured over cold 2% milk and ice. Unsweetened by default — add any syrup for flavor. Blonde Espresso is smoother if you find standard espresso too bitter. See our Starbucks guide for complete ordering tips.
At Dunkin'
Iced Coffee: Dunkin's flagship product and what they're famous for. Brewed with their proprietary blend, served over ice. Add flavor Shots (sugar-free) or Swirls (sweetened, creamy). A medium Dunkin' Iced Coffee (~$3.29) is arguably the best value in chain coffee. See our Dunkin' guide.
Iced Latte: Espresso + cold milk. Dunkin' uses their own espresso blend. The espresso is milder than Starbucks' — less bitter, more approachable. The default milk is whole milk (vs. Starbucks' 2%). Iced lattes at Dunkin' taste slightly creamier and less intense than Starbucks'.
At Dutch Bros
Iced Coffee: Not a menu focus — Dutch Bros specializes in espresso-based drinks, Rebels, and Faves. You can order an iced coffee, but it's not their strength.
Iced Latte: The default at Dutch Bros is espresso + half-and-half (breve), not 2% milk. This makes Dutch Bros lattes significantly richer and creamier — but also much higher in calories. Always specify "with 2% milk" or "with oat milk" if you want a lighter version. See our Dutch Bros guide.

Frequently Asked Questions
What is the difference between an iced latte and an iced coffee?
An iced latte is espresso + cold milk + ice. An iced coffee is brewed coffee + ice with a splash of milk optional. Lattes are creamier and milder; iced coffee has stronger coffee flavor. Different coffee bases (espresso vs. brewed) is the key distinction.
Which has more caffeine?
Iced coffee usually has more total caffeine. At Starbucks: Grande Iced Coffee = 165mg vs Grande Iced Latte = 150mg. Espresso is more concentrated per ounce but served in smaller quantities.
Is an iced latte or iced coffee cheaper?
Iced coffee is cheaper at every chain. Starbucks: $3.45 vs $5.25 (Grande). Dunkin': $3.29 vs $4.69 (Medium). The $1.80 daily gap = $432/year.
Is an iced latte just iced coffee with milk?
No. An iced latte uses espresso (concentrated, brewed under high pressure). Adding milk to iced coffee makes it "coffee with milk," not a latte. The espresso base is what defines a latte.
