Matcha Latte Cost Calculator

What does a homemade matcha latte really cost?

A latte has three cost parts: matcha, milk, and sweetener. This preset uses a 100 g bag of latte-grade matcha at $30, or $0.30 per gram. A 3 g latte uses $0.90 of matcha, and with about $0.45 of milk and syrup the total is roughly $1.35 per latte.

At five lattes a week against a $6 café latte, you'd spend about $6.75 at home versus $30 at the café, saving around $23 a week or about $1,210 a year. Enter your own prices to see your number.

How much matcha goes in a latte?

Ippodo Tea's latte recipe uses 1.5 teaspoons, about 3 g, whisked with 100 ml of 80 °C water and topped with 100 ml of milk. For a bigger 12 to 16 oz café-size drink, many people use 4 g or more. Each extra gram adds the price of one gram of matcha, so the per-gram cost matters most for latte drinkers.

Picking matcha for lattes

Milk and sweetener soften bitterness, so a pricey ceremonial matcha isn't required. A 2025 comparison of matcha grades found lower grades contain more polyphenols and fewer amino acids such as theanine, which explains why they taste more astringent straight but still work well with milk. Look at price per gram rather than tin price:

• $0.20 to $0.40 per gram: typical of larger culinary or latte bags
• $0.60 to $1.00 per gram and up: common for small tins of higher grades

These are examples, not a market survey; check current prices where you shop.

Milk is a real cost

Plant milks can cost twice as much as dairy per serving. Using 100 to 200 ml per latte, milk often costs more than the matcha itself when the matcha is a budget bag. Barista-style plant milks froth better but cost more again, so set the add-on field to match what you actually buy.

Freshness and bag size

A 100 g bag at five lattes a week lasts about six to seven weeks. Ippodo suggests using opened matcha within about a month for best flavor, so if you drink fewer lattes, a 30 to 40 g size may waste less even if it costs more per gram. Keep it sealed in a cool, dark cupboard away from strong odors.

When the café still wins

If you only buy a latte occasionally, a tin that goes stale before you finish it can cost more per drink than the café. The calculator's servings-per-tin and weeks-per-tin numbers make that easy to spot.
