How to Calculate Beverage Cost and Price Menus for Cafes and Milk Tea Shops

Beverage costing and menu pricing is the process of determining the total raw material costs that make up a finished product (including beverage ingredients, packaging, and wastage buffer), thereby establishing a selling price that covers operating expenses and generates net profit for the shop. Doing this right from the start allows shop owners to know exactly how much profit is made on every cup sold, avoiding the common trap of "high customer volume but zero profit at month's end."

Working with SMEs and F&B businesses in Vietnam, I've noticed the most common mistake among new owners is pricing items simply by looking at a competitor's menu and subtracting a few thousand dong to be "more competitive." This article provides a step-by-step guide to standardizing your cost sheets and pricing your menu realistically.

What Is Beverage Cost and What Does It Include?#

Beverage Cost is the total direct cost of raw materials required to produce a finished drink delivered to the customer, typically expressed as an absolute amount (VND) or as a percentage of the selling price (Cost %).

Many shop owners only factor tea, milk, and coffee into their cost of goods sold, overlooking numerous associated expenses. A standard drink cost calculation must include three components:

1. Main and secondary ingredients (Ingredients): Coffee beans, brewed tea, fresh milk, condensed milk, creamer, sugar, syrups, toppings (tapioca pearls, jellies), ice cubes.
2. Packaging and accessories (Packaging): Plastic/paper cups, lids, straws, take-away bags, napkins, cup sealing film.
3. Standard wastage buffer (Wastage buffer): Ingredients left behind in shakers and measuring jiggers, spilled ground coffee, or expired brewed tea/pearls discarded at the end of a shift.

Why Do Busy Shops Still End Up with Zero Profits at Month's End?#

Pricing a menu without a detailed cost breakdown leaves a shop vulnerable to three major financial leaks:

• Overlooking takeout packaging costs: A set of a hard plastic cup, dome lid, straw, and T-bag carrier can cost between 1,500đ and 3,000đ. For a 25,000đ milk tea, missing this cost means instantly losing nearly 10% of revenue.
• Uniform pricing across all channels: A 30,000đ drink sold in-store might be profitable, but keeping that same price on food delivery apps (with 20% - 30% commission fees) turns every order into an operating loss.
• Blind discounting campaigns: Without knowing the gross profit margin of each item, launching "Buy 1 Get 1 Free" or "30% Off Storewide" promos directly eats away at rent and payroll.

5 Steps to Accurately Calculate Beverage Costs for Small Shops#

To build an organized costing sheet, all you need is Excel or Google Sheets and these five sequential steps.

Step 1: Catalog Ingredients and Convert to the Smallest Unit#

You purchase supplies in cartons, bags, jugs, or cans, but baristas prepare drinks using grams (g), milliliters (ml), or individual units. Therefore, you must convert the purchase price down to the smallest preparation unit.

Hypothetical conversion examples:

• Unsweetened fresh milk: Buying a 1-liter (1,000 ml) carton for 32,000đ -> Unit cost: 32đ / ml.
• Roasted coffee beans: Buying 1 kg (1,000 g) for 200,000đ -> Unit cost: 200đ / g.
• Plastic cup + lid + straw + bag: Purchased by the carton, averaged out -> Unit cost: 1,800đ / set.

Step 2: Standardize Recipe Measurements (Recipe)#

A Standard Recipe specifies the exact number of grams or milliliters of each ingredient required to make a drink for fixed cup sizes (S, M, L). If staff prepare drinks based on "gut feeling," cost spreadsheets on paper become completely meaningless in practice.

Step 3: Calculate Ingredient and Packaging Costs Per Cup#

Multiply the recipe measurements from Step 2 by the unit costs from Step 1, then add the cost of the takeout packaging set.

Step 4: Add a Wastage Allowance (Wastage)#

In daily operations, 1 kg of coffee beans never yields exactly 50 phin servings of 20g due to grinder retention, spills, and machine rinses. Similarly, condensed milk always sticks to the bottom of the can. Add a wastage buffer (typically 5% to 10% on top of total ingredient costs) to keep calculations aligned with actual month-end figures.

Step 5: Plug Into the Complete Cost Formula#

Total Cost Per Cup = (Ingredient Cost + Packaging Cost) × (1 + Wastage Rate)

Real-World Example: Costing a Pearl Milk Tea (Size M - 500ml)#

Suppose a small bubble tea shop establishes a standard recipe for 1 cup of traditional Pearl Milk Tea with the following cost table:

Thus, the actual cost to produce this cup of milk tea is approximately 10,600đ.

How to Price Your Menu to Guarantee Profitability#

Once you have the 10,600đ figure, should you sell this drink for 25,000đ, 30,000đ, or 35,000đ? Here are three combined methods to guide your decision.

1. Pricing by Target Cost Percentage (Target Cost %)#

A standard formula in the F&B industry is:

Projected Selling Price = Total Cost Per Cup / Target Cost %

Depending on your shop model (street cart, small takeout counter, or spacious air-conditioned lounge), target cost percentages vary because gross profits must cover rent, payroll, and utilities:

• If your target cost is 35%: Selling price = 10,600 / 0.35 = 30,285đ (Round to 29,000đ or 30,000đ).
• If you run a large space needing a 25% cost ratio to cover overhead: Selling price = 10,600 / 0.25 = 42,400đ (Round to 42,000đ).

2. Cross-Pricing Strategy Across the Menu (Menu Engineering)#

Avoid rigidly applying a flat 30% or 35% across every single menu item. A well-designed menu typically segments products into three categories:

• Traffic Builders / Loss Leaders: E.g., Black coffee, Vietnamese iced milk coffee, or plain black tea. You can accept a slightly higher cost percentage to keep prices accessible, drawing steady daily foot traffic.
• Signature Drinks: The shop's flagship items that build brand identity, priced at the standard target cost with consistent sales volume.
• High-Margin Upsells: Toppings (crystal boba, cheese foam, egg pudding) or pastries. For example, a portion of cheese foam costs around 2,500đ but easily sells as a 10,000đ add-on. When customers add toppings, the gross margin of the entire drink spikes significantly.

3. Integrating Recipes into Digital Operations#

Calculating on Excel is a solid start, but to monitor costs daily in live operations, you need to sync your recipe sheets with a POS system.

By setting up recipe specs in modern POS platforms—such as those within the GoMetap ecosystem—every time a cashier rings up a cup of Pearl Milk Tea, the system automatically deducts 150ml of tea base, 30g of creamer, and 1 cup from inventory. Furthermore, pairing digital membership cards (on Apple Wallet or Google Wallet) for point accumulation rather than offering direct item discounts is an excellent way to protect gross margins while encouraging repeat visits.

Action Checklist for Shop Owners Today#

You don't need to overhaul your entire menu overnight. Start taking control of your profits with these six practical steps:

• List your top 10 best-selling items: Standardize costs for this group first, as they account for the bulk of your revenue.
• Update your supplier price list: Review invoices from the past month and convert all ingredients to grams, ml, or individual units.
• Audit takeout packaging costs: Factor in cups, lids, straws, carrier bags, and plastic spoons for every item.
• Measure actual preparation at the bar: Shadow your baristas to verify whether real-world portions match your standard recipe on paper.
• Build a high-margin topping menu: Offer at least 3-5 profitable toppings and train cashiers to suggest add-ons (upsell) at checkout.
• Schedule quarterly cost reviews (every 3 months): Prices for milk, sugar, and coffee fluctuate often; review your cost sheets each quarter to adjust recipes or prices in time.
