Dunkin’ Green Tea Price by Size (2026)

A 10-ounce Small hot green tea starts near $2.29, which puts it among the lower-priced drinks on the Dunkin’ menu with prices. Moving up a size adds about $0.40 each time, while the cup grows from 10 to 14 to 20 ounces. Since the price climbs more slowly than the cup, the Large works out about 33% cheaper per ounce than the Small.

Some locations ring up all hot teas at a single price, so green tea may match black or herbal tea there. Iced green tea has no separate published price; it is probably charged like black Dunkin’ iced tea at $2.79 to $3.39, though that match is unverified. Franchise owners set final prices, so confirm your store’s number in the Dunkin’ app.

Dunkin’ Donuts Green Tea Caffeine: Hot vs Iced by Size

Dunkin’ Donuts green tea caffeine is modest: about 70 mg in a hot Small or Medium and 140 mg in a Large, both reported as minimums. Iced green tea holds about 45, 67 and 91 mg in its 16, 24 and 32-ounce cups. Even a Large hot green tea stays well below the 210 mg in a Medium hot coffee.

The odd one out is the hot Medium, listed with the same caffeine as a Small despite 4 more ounces of water. On paper that makes it the most diluted hot cup at about 5 mg per ounce, against 7 mg in a Small or Large. Because the 70 mg figure is a minimum, a real Medium may land higher, while iced green tea sits near 2.8 mg per ounce in every size.

Green Tea Caffeine vs Black Tea and Coffee

Bold Breakfast Black is listed at roughly 90 mg (Small or Medium) and 180 mg (Large), 20 to 40 mg more than green tea. Per dollar, a Large green tea gives about 45 mg and a Medium Dunkin’ hot coffee about 78 mg. Decaf black tea on the Dunkin’ hot tea menu has under 2 mg. A Large green tea is 35% of the 400 mg a day the FDA says is not generally associated with negative effects in most healthy adults.

Dunkin’ Donuts Green Tea Calories and Sugar

Plain Dunkin’ Donuts green tea calories are close to zero: a hot cup has 0 calories and unsweetened iced green tea about 5 in every size. Neither version contains sugar or dairy until you add something. That puts green tea beside black coffee and unsweetened iced tea as the lightest drinks on the menu.

Sweetened iced green tea changes the math, at about 70 calories in a Small and 100 in a Medium. That Medium holds about 25 g of sugar, 50% of the 50 g Daily Value the FDA sets for a full day of added sugar. Ordering it unsweetened with a flavor shot keeps sugar at zero and still adds taste.

What’s in Dunkin’ Green Tea and How It’s Made

Hot green tea at Dunkin’ is Harmony Leaf Green, a full-leaf tea packed in a pyramid sachet and steeped in hot water. It arrived on November 2, 2016, when Dunkin’ moved its whole hot tea line to full-leaf sachets alongside Bold Breakfast Black and three caffeine-free herbals. It is the only green tea among Dunkin’s six hot teas, and a plain cup has 0 calories and 0 g of sugar.

Iced green tea is green tea served over ice, either unsweetened (about 5 calories) or sweetened (about 100 in a Medium). Green tea is also the classic base for Dunkin’ Refreshers, which combine it with fruit flavor. For every tea Dunkin’ sells, hot and iced, start with our complete Dunkin’ tea menu.

How Green Tea Differs From Dunkin’ Matcha

Both come from the same tea plant, but green tea is steeped and the leaves stay behind, while matcha is ground leaf mixed straight in. Dunkin’ blends a sweetened matcha powder with milk, so a Medium Dunkin’ iced matcha latte lands near 180 calories.

Allergen and Diet Notes

Plain green tea is just tea and water. Most swirls contain dairy, and shared equipment means cross-contact can happen. Dunkin’ publishes an official allergen guide, and our allergen and ingredient breakdown walks through it.

Flavor Shots, Swirls and Other Green Tea Add-Ins

Green tea can take the same two flavor systems as Dunkin’ coffee, and your choice sets the calorie count. Unsweetened flavor shots such as Raspberry, Blueberry or Coconut add aroma with no sugar. Sweet swirls are creamy syrups, and each pump adds roughly 50–55 calories plus 12 g of sugar.

Standard builds use 2 pumps for a Small, 3 for a Medium and 4 for a Large, with no charge for those pumps. Extra pumps typically add $0.10 to $0.25 each, and our guide to every Dunkin’ flavor shot and swirl lists them all. The sweetened-plus-swirl row below is the one to watch, at about 61 g of sugar in a single Medium.

Best Value: Which Green Tea Size and Order to Buy

Measured by the ounce, the Large is the clear value at about 15.4¢, while a Small costs 48% more per ounce and a Medium 24% more. The Medium returns the fewest milligrams per dollar (26 mg), because its reported caffeine matches the Small at a higher price. A Large returns the most caffeine for each dollar, about 45 mg against 31 mg for a Small.

Two Smalls cost $4.58 for the same 20 ounces and caffeine as one Large at $3.09, so the single cup saves $1.49. Green tea also keeps breakfast cheap: a Medium costs $2.00 less than a Medium hot matcha latte. The second table below prices full orders, including green tea with an Egg and Cheese Wake-Up Wrap.

Cheapest Way to Get a Fruity Green Tea

A Medium Refresher costs about $4.29 for 120 to 170 calories. A Medium unsweetened iced green tea with a Raspberry or Blueberry shot gives fruit flavor for 10 to 15 calories. Using the $3.09 black iced tea price as a stand-in, the swap saves about $1.20, so confirm your store’s price first.

Best Dunkin’ Green Tea Orders, Ranked by the Numbers

The best green tea order depends on your goal: fewer calories, more caffeine, fruit flavor or a sweeter cup. Each pick below is ranked on the menu’s own numbers rather than taste claims. All of them use standard menu options, so they work at the speaker or in the app.

Two rules cover most of these picks: go unsweetened with a shot for flavor without sugar, and go Large for more caffeine per dollar. If sweetness matters, cutting the swirl to one pump keeps a Medium near 55–60 calories instead of 155–170. Our ranking of the healthiest Dunkin’ drinks shows where green tea lands overall.

Dunkin’ Green Tea vs Matcha, Black Tea and Other Drinks

Green tea sits in the middle of Dunkin’s tea caffeine range, below black tea and well above decaf and herbal tea. A Medium hot green tea costs $2.69 with about 70 mg, while a Medium hot matcha latte costs $4.69 and an iced matcha latte delivers about 120 mg. Black tea gives more caffeine for less, at about 90 mg for $2.49.

Calories split the menu into two clear groups. Plain teas and black coffee stay at 0 to 5 calories, while the milk-based Dunkin’ chai latte reaches about 290 calories and 40 g of sugar in a Medium. A Medium iced matcha latte sits near 180 calories and a Medium iced espresso latte near 170, so anything made with milk carries far more calories than plain tea.

Pick the Right Green Tea Order for Your Goal

How to Order Hot or Iced Green Tea at Dunkin’ (App, Drive-Thru, In Store)

Order in this sequence: size, hot or iced, green tea, then sweetened or unsweetened and any flavor. Naming green tea matters, because a plain iced tea order gets black tea by default. Hot green tea comes as just tea and water, so milk, sugar or a flavor shot only goes in when you ask for it.

Ordering ahead in the Dunkin’ app shows what your own store charges, since green tea prices differ between franchises. Signed-in Dunkin’ Rewards members also earn points on qualifying purchases toward free drinks. The Dunkin’ cup size chart lists the ounces in every hot and iced cup if you are deciding between sizes.

1. Pick a size: hot 10, 14 or 20 oz; iced 16, 24 or 32 oz (no confirmed Extra Large).
2. Ask for green tea by name rather than just “iced tea”.
3. Choose unsweetened or sweetened, then add an unsweetened shot for flavor without sugar.

Final Verdict: Is Dunkin’ Green Tea Worth It?

Dunkin’ green tea is worth ordering when you want a low-cost, zero-calorie cup with light caffeine. A hot cup costs $2.29 to $3.09, stays at 0 calories in every size and reaches about 140 mg of caffeine in a Large. Unsweetened iced green tea is nearly as light at about 5 calories, and our Dunkin’ calorie chart shows how few drinks match that.

The strongest value is a Large hot green tea, while a Medium unsweetened iced green tea with a fruit shot is the best flavored pick. Skip sweetened tea with swirls, which reaches about 250–265 calories in a Medium. For a creamier green drink, the matcha latte costs about $2.00 more, and the full Dunkin’ drinks menu lists every other option.

Prices here are typical 2026 US prices, and each franchised store sets its own. Nutrition and caffeine numbers are published estimates, and some caffeine figures are listed as minimums. When a figure is missing, such as an iced green tea price, the answer says so.
