What Does a Cup Actually Cost?

Powder is priced by weight, which makes comparison awkward. Converting to cost per cup fixes that.

The calculation

servings = package weight ÷ per-serving amount
cost per cup = price ÷ servings

At 20 g per 150 ml, a 300 g package gives 15 servings.

• 300 g at ¥1,500 → ¥100 per cup
• 300 g at ¥2,600 → about ¥173 per cup
• 1 kg at ¥5,000 → ¥100 per cup

Strength moves the number

At 15 g per serving, 300 g yields 20 cups. Same package price, lower cost per cup.

You control the serving size, so you control the unit cost — not something bottled drinks allow.

With milk

A latte uses 18 g, so less powder, but milk costs something. At ¥200 per litre, 150 ml adds roughly ¥30.

Calculate the whole cup or the figure will mislead you.

Comparisons

A café matcha latte typically runs several hundred yen. Making it at home lands well below that.

Bottled tea sits around ¥100–150. Sweetened matcha is comparable or higher — but they are different categories, since one is unsweetened and functions as hydration.

Positioned as something you drink for the taste rather than for fluid intake, the comparison that fits is with snacks.

Bulk is conditional

Cost per gram falls with size and means nothing if the package outlasts its useful life.

Sellers suggest finishing opened matcha within two weeks to a month. A kilogram is 50 servings — close to two months at one cup daily.

Cost-per-cup arithmetic only holds if you finish the package while it is still good.

Contents differ at the same price

Two 300 g packages at the same price can have very different compositions. Ingredient lists run by weight, so the order tells you where the money went.
