Ever wondered how many calories are actually in your daily cup of tea? Plain brewed tea is nearly calorie-free, but the milk, sugar, honey, and syrups you add can turn a healthy drink into a 100–300 kcal indulgence. This Tea Calories Per Cup Calculator lets you see exactly where those calories come from, based on your cup size and the specific milk and sweeteners you use.
It's perfect for tea lovers tracking their daily intake, anyone on a weight-management plan, or simply the curious. The calculator covers black, green, white, oolong, herbal, and matcha teas, with common milk options from skim to heavy cream and sweetener choices like sugar and honey. Quick presets for classic British tea, London fog, matcha latte, and plain green tea let you get an answer in seconds — then tweak the ingredients to match your exact mug.
Just enter your cup size, choose your additions, and hit Calculate for a full calorie breakdown.
🧮 Tea Calories Per Cup
Estimate calories in your cup of tea, including milk, sugar, and honey.
How to Use This Tool
- Select your tea type. Plain brewed black, green, white, oolong, and herbal teas add almost no calories; matcha powder adds a small amount because you drink the ground leaves.
- Enter your cup size in cups, fluid ounces, or millilitres. The calculator scales every ingredient to that volume.
- Set the amounts of sugar and honey in teaspoons. Leave them at 0 for an unsweetened brew.
- Add milk or cream. Pick a unit for the amount (fl oz, tbsp, or ml), then choose the milk type from whole, 2%, skim, oat, almond, half & half, or heavy cream.
- Press Calculate for the total and a per-ingredient breakdown.
Formula Explained
Total calories come from four parts:
Total kcal = base tea + sugar + honey + milk/cream
- Base tea: 0 kcal for plain steeped tea; about 6 kcal per 240 ml for matcha.
- Sugar: 1 tsp granulated sugar ≈ 16 kcal.
- Honey: 1 tsp honey ≈ 21 kcal.
- Milk/cream: calories depend on the milk type and the volume added, using USDA-derived values per 100 ml.
This is why the same cup size can range from under 5 kcal to more than 200 kcal depending only on what you add. Calorie values follow USDA FoodData Central averages.
Reference Table: Add-In Calories
| Add-in | Amount | Approx. kcal |
|---|---|---|
| Sugar | 1 tsp (4 g) | 16 |
| Honey | 1 tsp (7 g) | 21 |
| Whole milk | 30 ml (1 fl oz) | 19 |
| 2% milk | 30 ml | 15 |
| Skim milk | 30 ml | 11 |
| Oat milk | 30 ml | 14 |
| Almond milk | 30 ml | 5 |
| Half & half | 30 ml | 39 |
| Heavy cream | 30 ml | 102 |
Worked Examples
Plain black tea with a splash of whole milk: 240 ml black tea (0 kcal) + 1 fl oz whole milk (~19 kcal) = about 19 kcal per cup.
Sweet chai-style cup: 240 ml black tea (0 kcal) + 2 tsp sugar (32 kcal) + 1 fl oz half & half (39 kcal) = about 71 kcal per cup.
Matcha latte: 240 ml matcha (6 kcal) + 4 fl oz oat milk (~56 kcal) = about 62 kcal per cup.
Tips & Best Practices
- Barista oat and soy milks are often sweetened; check the carton because calories can be 20–30% higher than the unsweetened version.
- Flavored syrups are a hidden calorie source. One pump of vanilla or caramel syrup adds roughly 20–25 kcal — treat them like a sweetener and add them manually if you know the brand.
- If you drink several cups a day, the milk and sugar calories multiply. A 3-cup habit with 2 tsp sugar each adds about 96 kcal per day.
- Use a kitchen scale or measuring spoon at least once to calibrate what “one teaspoon” looks like in your cup.
Frequently Asked Questions
Does plain tea itself contain calories? Black, green, white, oolong, and herbal teas brewed from leaves contain negligible calories — usually less than 2 kcal per cup. Matcha is the exception because the whole leaf powder is consumed, adding roughly 6 kcal per 240 ml serving.
Why do milk calories vary so much? The fat content drives the difference. Skim milk is about 35 kcal per 100 ml, whole milk about 62, half & half about 130, and heavy cream about 340. A small splash has little impact, but a large café-style pour does.
Are zero-calorie sweeteners counted? No. This calculator counts granulated sugar and honey only. Stevia, monk fruit, sucralose, and similar non-caloric sweeteners add negligible calories and can simply be left at 0.
