TeaWisp Editorial · Updated October 29, 2026
To estimate the leaf cost of one preparation, divide the package price by its net tea weight, then multiply by the dry leaves you use. Compare the same currency and the same serving definition. A cheap-looking pack is not necessarily the cheaper daily choice.
Choose what you mean by a cup
A small tasting cup and a large mug are different servings. Start with a recipe for the tea you intend to drink, not an arbitrary spoonful. Record its dry leaf weight and water amount. This page is a budgeting calculation; it does not recommend increasing or reducing a tea’s dose to meet a price target.
Use a transparent example
Imagine a 50 g pack costing US$15 and a preparation using 3 g. These are invented arithmetic inputs, not a TeaWisp price or product recipe. US$15 ÷ 50 g × 3 g = US$0.90 in leaves per preparation. The pack contains 16 complete 3 g portions with 2 g remaining, rather than a guaranteed 17 identical preparations. Your actual weighed portions may vary.
Add costs without hiding assumptions
First calculate leaf-only cost so you can compare packages fairly. Then consider delivery, tax or duties shown for your destination, plus any equipment you actually need. If you allocate a US$5 delivery charge entirely to that same hypothetical pack, its landed cost becomes US$20 and the leaf allocation is US$1.20 per 3 g. In a mixed order, explain how you divide delivery rather than silently charging it to every pack.
Treat repeat infusions separately
Several infusions from the same leaves do not require several fresh leaf doses, but their volume and taste may differ. Count the servings you actually enjoy instead of relying on a promised number of resteeps. Water, energy and equipment are outside the leaf-only formula. If you discard unused tea, the cost of the tea you drink is higher than a calculation assuming every gram is used.
Buy an amount you can use
Check net weight, tea type, current price and delivery terms on the actual listing. A smaller pack can make sense when trying an unfamiliar tea, even if its price per gram is higher. Decide from your budget and likely use; this calculation does not predict quality or savings. Ask about unclear pack details before ordering.
| Example | Leaf cost per preparation |
|---|---|
| US$15 / 50 g; dose 3 g | US$0.90 |
| US$20 including allocated delivery / 50 g; dose 3 g | US$1.20 |
Questions
Can I compare two teas with the same teaspoon?
Not reliably by weight. Leaf shapes fill a spoon differently; use each tea’s recipe and a measured dose.
Does lower cost mean better value?
Only if the tea and quantity suit you. Preference, usable information and waste matter too.
