How to Calculate Coffee Cost Per Cup for Your Café or Canteen
Most café and canteen operators know what they pay per kilogram for coffee. Fewer know their actual cost per cup — and fewer still have calculated whether their selling price is covering ingredient cost, equipment depreciation, milk, and labour.
This guide provides the framework to calculate coffee cost per cup accurately, and the breakeven margins needed to make bulk buying decisions.
The Cost Components You Need to Track
For filter coffee (decoction method):
- Coffee powder cost per kg
- Milk cost per litre
- Sugar cost per kg
- Fuel/electricity for heating
- Equipment depreciation (filter device, vessel, strainer)
- Labour time
For instant coffee:
- Instant powder cost per kg
- Milk cost per litre
- Sugar cost per kg
- Fuel/electricity
- Hot water equipment cost
Most buyers track only #1. This creates systematic underpricing.
Filter Coffee Cost Calculation (Per Cup)
For a standard 150 ml filter coffee cup (South Indian style):
| Ingredient | Quantity | Unit Cost | Cost per Cup |
|---|---|---|---|
| Filter coffee powder (60:40) | 8–10 g decoction yield | ₹300/kg | ₹2.40–3.00 |
| Full-fat milk | 100 ml | ₹65/litre | ₹6.50 |
| Sugar | 8 g | ₹45/kg | ₹0.36 |
| Fuel/electricity | — | estimate | ₹0.30 |
| Total ingredient cost | — | — | ₹9.56–10.16 |
At these inputs, a 150 ml filter coffee cup costs approximately ₹10 in ingredients alone. This does not include overhead, labour, equipment, or profit.
Common selling prices and implied margins:
| Selling Price | Ingredient Cost | Gross Margin | Covers What |
|---|---|---|---|
| ₹15 (Darshini) | ₹10 | 33% | Marginal — covers ingredients + partial overhead |
| ₹25 (small café) | ₹10 | 60% | Covers overhead, some profit |
| ₹45 (mid-tier café) | ₹10 | 78% | Strong margin — sustainable |
| ₹80 (premium café) | ₹12 (70:30 blend) | 85% | Excellent — specialty positioning justified |
Instant Coffee Cost Calculation (Per Cup)
For a 150 ml cup using agglomerated instant coffee with hot milk:
| Ingredient | Quantity | Unit Cost | Cost per Cup |
|---|---|---|---|
| Instant coffee (agglomerated) | 6 g | ₹750/kg | ₹4.50 |
| Full-fat milk | 80 ml | ₹65/litre | ₹5.20 |
| Sugar | 8 g | ₹45/kg | ₹0.36 |
| Electricity (kettle/urn) | — | estimate | ₹0.15 |
| Total ingredient cost | — | — | ₹10.21 |
Instant coffee is not significantly cheaper per cup than filter coffee at B2B input prices. The cost difference narrows at scale because of how efficiently instant dissolves (no decoction waste, no grounds).
Tea Cost Calculation (Per Cup)
For a 200 ml masala chai cup:
| Ingredient | Quantity | Unit Cost | Cost per Cup |
|---|---|---|---|
| Assam CTC dust | 3 g | ₹280/kg | ₹0.84 |
| Full-fat milk | 120 ml | ₹65/litre | ₹7.80 |
| Sugar | 10 g | ₹45/kg | ₹0.45 |
| Spice blend | 1.5 g | ₹800/kg | ₹1.20 |
| Fuel | — | estimate | ₹0.30 |
| Total ingredient cost | — | — | ₹10.59 |
Tea has a lower powder cost but a higher milk-to-volume ratio, resulting in similar per-cup cost to filter coffee.
How Bulk Buying Affects Your Cost
Buying in larger quantities reduces the input cost per kg:
| Quantity | Filter Coffee (60:40) est. price | Saving vs. 5 kg |
|---|---|---|
| 5 kg | ₹320/kg | — |
| 25 kg | ₹295/kg | ₹1.25 per cup |
| 100 kg | ₹270/kg | ₹2.50 per cup |
At 200 cups per day, a ₹2.50 per cup saving equals ₹15,000 per month. Bulk buying is the single most direct lever for improving margins without raising prices.
The Monthly Budget Calculator
Use this formula to estimate your monthly spend:
Monthly spend = cups per day × 30 × cost per cup
| Business Scale | Daily Cups | Monthly Ingredient Cost (est.) |
|---|---|---|
| Small café / tiffin | 50 | ₹14,000–18,000 |
| Mid-size Darshini | 200 | ₹55,000–72,000 |
| Corporate canteen | 500 | ₹1,40,000–1,80,000 |
| Large canteen | 1,000 | ₹2,80,000–3,60,000 |
Using This to Make Better Supplier Decisions
The question when evaluating a supplier is not just price per kg — it is price per cup after accounting for yield, consistency, and waste.
A cheaper powder with more moisture content or inconsistent grind will produce lower yield per kg and require more powder per cup. A ₹20/kg cheaper powder that requires 15% more per cup is actually more expensive.
Ask your supplier: what is the recommended usage per cup, and what is the yield from their specific product?
