Calculating tea margins is like peeling an onion – there are more layers than you expect. Beyond the obvious tea bag, you've got hot water, milk, sugar, side dishes and tableware. Each component chips away at your profit if you're not tracking it properly.
All cost items for tea
Tea looks straightforward, but here's what actually goes into that cup:
- Tea bag or loose tea
- Hot water (gas/electricity for boiling)
- Milk, sugar, honey
- Side dishes (cookie, pastry)
- Tableware (cup, saucer, spoon)
- Dishwashing and staff
💡 Example:
Tea with cookie for €3.50 incl. VAT:
- Tea bag: €0.15
- Water + energy: €0.05
- Milk (portion): €0.08
- Sugar: €0.02
- Cookie: €0.35
- Tableware + dishwashing: €0.10
Total cost price: €0.75
VAT and sales price conversion
Restaurant tea falls under 9% VAT. You'll want to calculate margins based on the price excluding VAT – that's your actual revenue.
⚠️ Note:
Most operators skip the energy costs for boiling water. That's the kind of thing you only learn after closing your first month at a loss – it adds €0.05-€0.10 per cup with today's energy prices.
Calculate margin with formula
The margin formula for tea breaks down like this:
Margin % = ((Sales price excl. VAT - Cost price) / Sales price excl. VAT) × 100
💡 Example calculation:
Tea with cookie €3.50 incl. VAT:
- Sales price excl. VAT: €3.50 / 1.09 = €3.21
- Cost price: €0.75
- Margin: ((€3.21 - €0.75) / €3.21) × 100 = 76.6%
That's a solid margin for beverages.
Side dishes make the difference
Plain tea delivers 85-90% margins. But those cookies and pastries? They'll drag your numbers down fast.
- Tea without side dish: 85-90% margin
- Tea with cookie: 70-80% margin
- Tea with pastry: 60-75% margin
Calculate water energy costs
Boiling 1 liter costs roughly €0.15-€0.25 in gas or electricity (varies with current rates). For a 250ml cup, that's €0.04-€0.06 per serving.
💡 Practical tip:
Switch to an electric kettle instead of stovetop boiling. It's 3-4x more efficient and saves €0.03-€0.04 per cup.
Healthy tea margin benchmarks
Standard margins for hot beverages in hospitality:
- Tea without side dish: 80-90%
- Tea with cookie: 70-80%
- Tea with pastry: 65-75%
- Coffee for comparison: 75-85%
⚠️ Note:
Margins below 65% mean you're leaving money on the table. Review your side dish costs or bump up pricing.
How do you calculate the margin on tea? (step by step)
Gather all cost prices
Add up: tea bag, water + energy, milk, sugar, side dish and tableware. Don't forget the energy costs for boiling water (€0.04-€0.06 per cup).
Calculate sales price excluding VAT
Divide your menu price by 1.09 to remove 9% VAT. For example: €3.50 / 1.09 = €3.21 excluding VAT.
Calculate your margin percentage
Use the formula: ((Sales price excl. VAT - Cost price) / Sales price excl. VAT) × 100. A healthy margin for tea is between 70-85%.

Frequently asked questions
Do I really need to include energy costs for water?
Absolutely, especially with current energy prices. Boiling water runs €0.04-€0.06 per cup and that adds up fast with high tea volume.
What is a normal margin on tea in a restaurant?
Tea without side dish hits 80-90% margin. With cookie: 70-80%. With pastry: 65-75%. Anything below 65% needs attention.
How do I calculate the costs of loose tea vs tea bags?
Tea bags run €0.10-€0.20 per piece. Loose tea costs €0.05-€0.15 per cup, but factor in extra prep time. Labor costs can offset the savings.
Do I need to include VAT in my margin calculation?
Never calculate margins with VAT included. Divide your menu price by 1.09 to get the excluding-VAT price for accurate margin math.
What if my tea margin is too low?
Review your side dish costs first, consider cheaper alternatives, or increase menu prices by €0.25-€0.50. Small bumps make big differences.
Should I track different tea varieties separately?
Yes, premium teas like Earl Grey or herbal blends cost more than basic black tea. Track them separately to avoid margin surprises.
How often should I recalculate tea margins?
Monthly minimum, or whenever ingredient costs shift significantly. Energy price changes alone can swing your margins by 2-3%.
