How Many Servings in a Kilogram?
Putting matcha on a menu means knowing the per-serving cost. The arithmetic is simple.
The calculation
servings = package weight ÷ per-serving amount
cost per serving = purchase price ÷ servings
At 20 g, one kilogram gives 50 servings. At 18 g, about 55. At 15 g, about 66.
Purchase price of ¥5,000 per kilogram works out to ¥100 per serving at 20 g, or about ¥91 at 18 g.
Format changes the amount used
| Preparation | Typical amount | Servings per kg |
|---|---|---|
| Iced (water) | 20 g | 50 |
| Hot | 20 g | 50 |
| Latte (milk) | 18 g | ~55 |
| Shaved ice syrup | 20–25 g | 40–50 |
Lattes use less because dairy contributes body.
Add the secondary costs
A latte brings milk. At 150 ml from a ¥200 litre, roughly ¥30.
Per-serving cost is powder plus milk plus cup, lid, and straw. For takeaway, packaging weighs more heavily than people expect.
Build in yield loss
Calculated servings do not fully materialize.
Measuring variance, residue in the container, remakes. A few percent disappears. Estimating servings about ten percent below the calculation brings you closer to reality.
Confirm you can finish it
Fifty servings from a kilogram means 25 days at two per day.
Powder deteriorates after opening. Matcha sellers commonly cite two weeks to a month, which puts low-volume operations at a disadvantage with large packages.
Smaller, more frequent purchases can win on both quality and effective cost.
Set strength before price
Setting the price first and adjusting strength afterward produces inconsistency.
Decide the strength you want to serve, derive servings and cost from that. That order gives a stable menu item.
