Tea house owners consistently underestimate their true margins because they calculate tea and treats separately instead of as a combined offering. This leads to pricing mistakes that can cost you thousands in lost profit each month.
Why tea house margin is different
A tea house differs from a restaurant because your main product (tea) has a very low cost price, but also a lower selling price. Your business model depends on the combination of tea and small treats.
💡 Example typical tea house revenue:
- Tea: 60% of items, 35% of revenue
- Pastries/cookies: 30% of items, 45% of revenue
- Lunch items: 10% of items, 20% of revenue
Calculate your food cost per product group
For a tea house you calculate the margin per product category separately, because they vary greatly:
- Tea: Low cost price (€0.15-0.40 per pot), low selling price (€2.50-4.50)
- Pastries: Higher cost price (€1.20-2.80 per piece), higher selling price (€3.50-6.50)
- Savory snacks: Variable cost price (€0.80-3.20), selling price (€2.50-8.50)
💡 Example margin calculation tea:
You sell Earl Grey tea for €3.20 (incl. 9% VAT)
- Selling price excl. VAT: €3.20 / 1.09 = €2.94
- Cost price tea bag + water + milk/sugar: €0.25
- Food cost: (€0.25 / €2.94) × 100 = 8.5%
Margin: 91.5% - extremely high!
Calculate blended margin
You calculate your total tea house margin by taking all product groups together, weighted by revenue share.
💡 Example total calculation:
Daily revenue €450 (excl. VAT):
- Tea: €160 revenue, €15 cost = 9.4% food cost
- Pastries: €200 revenue, €65 cost = 32.5% food cost
- Lunch: €90 revenue, €28 cost = 31.1% food cost
Total: €108 cost on €450 revenue = 24% food cost
Total margin: 76%
Specific points of attention for tea houses
At a tea house there are additional cost items that affect your margin. From years of working in professional kitchens, I've seen these overlooked costs add up quickly:
- Packaging: Tea bags, crockery, napkins cost €0.05-0.15 per customer
- Fresh products: Pastries have short shelf life, plan purchases carefully
- Seasonal fluctuations: Winter = more hot tea, summer = iced tea and cold drinks
- Sitting time: Guests stay for a long time, calculate revenue per hour per table
⚠️ Note:
Include packaging costs (tea bags, sugar packets) in your cost price. With 200 cups of tea per day this costs you €30-60 per month extra.
Optimization tips for tea house margin
Increase your margin by smartly steering your product mix:
- Promote premium teas: Specialty teas often have a higher selling price at the same cost price
- Homemade pastries: Baking yourself gives 15-25% better margin than purchased
- Tea-pastry combinations: Bundle offers increase average transaction value
- Seasonal menu: Hot chocolate in winter, iced tea in summer
💡 Example optimization:
By getting 30% of your guests to add a slice of cake:
- Extra revenue: €4.50 per cake (excl. VAT: €4.13)
- Extra cost: €1.40 per cake
- Extra margin: €2.73 per cake = 66% margin
With 60 extra cakes per week = €8,500 extra margin per year!
Benchmark figures tea house
Common margins for tea houses:
- Tea only: 85-95% margin
- Purchased pastries: 65-75% margin
- Homemade pastries: 75-85% margin
- Total tea house concept: 70-80% margin
If you're below 65% total margin, check your purchases and product mix. Tea houses can achieve high margins through the low cost price of tea.
How do you calculate your tea house margin? (step by step)
Split your revenue per product group
Divide your daily revenue into tea, pastries, lunch items and other products. For each group, note the revenue excl. VAT (divide by 1.09). This gives you insight into where you make your money.
Calculate cost price per product group
For each group, add up all purchasing costs: ingredients, packaging, and any extras like sugar and milk. Don't forget small cost items like tea bags and napkins.
Calculate weighted total margin
Calculate per group: (purchasing costs / revenue excl. VAT) × 100 = food cost %. Your total margin = 100% - weighted average food cost of all groups combined. This is your true tea house margin.
✨ Pro tip
Track your tea-to-treat attachment rate every 2 weeks - aim for 75% of tea customers to order a pastry. If you're below this, test combo pricing like "Tea + Scone for €6" to boost average transaction value.

Frequently asked questions
Why is my tea house margin so low despite cheap tea?
Your margin is probably being squeezed by expensive purchased pastries or an incorrect product mix. Check if you're selling enough tea relative to more expensive products, and consider baking yourself for better margins.
Should I include packaging costs in my cost price?
Yes, absolutely. Tea bags, sugar packets, stirrers and napkins cost €0.05-0.15 per customer. With 1000 customers per month this is €50-150 in extra costs that will squeeze your margin if you don't account for them.
Is it worth baking myself for my tea house?
Often yes. Homemade cakes and cookies have 15-25% better margin than purchased, plus you have control over quality and ingredients. Do factor in labor costs and extra equipment in your calculation.
