Coffee Drink Profit Calculator
Enter your coffee dose (grams), the cost per kg of your coffee beans, the milk volume and cost per litre, any syrup or extra costs, and the cup and lid cost. The calculator gives you total drink cost, cost percentage at your current price, and the selling price needed to hit your target margin.
How to use this tool
- 1Enter the coffee dose in grams - a standard double espresso uses 18-22g. Adjust to your actual recipe.
- 2Enter the price per kg of your coffee beans from the supplier invoice.
- 3Enter the milk volume in ml - a flat white uses around 160ml, a latte 220ml, a cappuccino 120ml.
- 4Enter the milk price per litre.
- 5Enter cup and lid cost, and any syrups or extras. Then enter your selling price and target cost percentage to see margin.
Formula used
Example
Coffee cost: 18 x 0.028 = 0.50. Milk: 160 x 0.0014 = 0.22. Cup and lid: 0.16. Total: 0.88. At 4.50 selling price, cost percentage is 19.6% - within the 20-25% cafe benchmark. Profit per drink before labor and overhead: 3.62.
Coffee: 0.60. Milk: 0.35. Syrup: 0.23. Cup: 0.14. Total: 1.32. At 5.00 price, cost is 26.4% - slightly above a bare benchmark but the syrup surcharge customers often pay more for flavoured drinks. Adding a 0.50 surcharge brings the cost percentage to 22%.
Common use cases
- Calculating the real cost of every drink on a cafe menu before setting prices
- Deciding whether to add a surcharge for alternative milks (oat, almond, soy) and what the correct surcharge is
- Understanding the impact of switching to a more expensive single-origin coffee on your margin
- Identifying which drinks have the best and worst margins to inform menu promotion decisions
- Calculating the break-even number of coffees per day to cover fixed costs
Common mistakes
- Not including consumables like cups, lids, napkins, and stirrers - these add 10-20% to the apparent ingredient cost.
- Using a single milk price without accounting for alternative milks - oat and almond milk typically cost 2-3x cow's milk and require a surcharge.
- Underestimating coffee yield - a grinder that wastes 5% of coffee through clumping or purging adds real cost. Track coffee usage against sales to find your actual yield.
- Ignoring the cost of training-related waste during staff ramp-up - new baristas pull more failed shots.
Frequently asked questions
What cost percentage should a cafe target for coffee drinks?
Most cafes target 18-25% ingredient cost for espresso-based drinks. The low ingredient cost relative to selling price is what makes coffee a high-margin product. However, coffee businesses have high labor cost relative to drink volume, so a low drink cost percentage is essential to make the economics work.
How much does alternative milk cost to add?
Oat and soy milk typically cost 1.50-2.50 per litre compared to 0.80-1.40 for full-fat cow's milk. The additional cost for a flat white with oat milk (using 160ml) is around 0.20-0.35. Most cafes charge a 0.50-0.80 surcharge for alternative milks, which more than covers the cost difference.
How do I calculate my coffee cost per shot?
Take the price per kg of beans and divide by 1000 to get cost per gram. Multiply by your dose in grams. For example, 28.00/kg coffee with an 18g dose costs 28/1000 x 18 = 0.504 per double shot. For a single shot at 9g, the cost is 0.252.
Should I include milk steaming waste?
Yes, if significant. Baristas often discard unused steamed milk from pitchers that was prepared but not used. Some operations track milk waste at 10-15% above theoretical usage. If your actual milk usage is consistently higher than calculated, add a 10% waste factor to your milk cost.
