Comparing Prices per Serving
Powder is priced by weight, which makes shelf comparison awkward. Converting to cost per serving fixes it.
The calculation
servings = package weight ÷ per-serving amount
cost per serving = price ÷ servings
The standard is 20 g per 150 ml, so 300 g gives 15 servings.
- 300 g at ¥1,500 → ¥100 per serving
- 300 g at ¥2,600 → about ¥173
- 1 kg at ¥5,000 → ¥100
Strength moves the number
At 15 g per serving, 300 g yields 20 cups. Same package price, lower cost per cup.
You set the serving size, so you set the unit cost — not available with bottled drinks.
With milk
A latte uses 18 g, so less powder, plus the milk. At ¥200 per litre, 150 ml adds roughly ¥30.
Total the cup or the figure misleads.
What to compare against
Café matcha latte — several hundred yen. Home preparation lands well below.
Bottled tea — ¥100–150. Sweetened matcha is comparable or higher, though the categories differ: one is unsweetened and functions as hydration.
Positioned as something you drink for the taste rather than for fluid intake, snacks are the fairer comparison.
Bulk is conditional
Cost per gram falls with size, and means nothing if the package outlasts its useful life.
Post-opening guideline: two weeks to a month. A kilogram is 50 servings — close to two months at one a day.
The arithmetic only holds if you finish it while it is good.
Contents differ at matching prices
Two 300 g packages at the same price can be built very differently.
Ingredient lists run by weight, so the order shows where the money went.
