Private equity money keeps flowing into budget coffee chains. With deep pockets, these chains buy beans and supplies in bulk, using economies of scale to drive costs down. Meanwhile, independent café owners who set prices by eyeballing the shop next door — without knowing their own true cost per cup — are in a far more precarious spot than they used to be, unable to tell whether each sale turns a profit or a loss. This piece walks through café cost accounting step by step, from converting each ingredient into a per-cup cost to totaling the full cost of a drink, and on to the formula for setting a price that builds in your target margin. By the end, you'll be able to calculate exactly what your best-selling drink costs to make — and what you need to charge to actually make money on it.
Why "A Little Cheaper Than the Shop Next Door" Leads to Losses
A price set by gut feeling has no foundation. Pricing off the shop next door means following their cost structure, not reflecting your own. If that shop buys beans in bulk at a discount, the moment you match their price tag, you may be losing money on every cup without even realizing it. That's how a café ends up busier than ever, with more customers coming through the door, while the bank balance at month's end never moves.
The starting point for costing a café menu is pinning down the "cost per unit." Looking only at your total monthly ingredient spend won't tell you which drinks turn a profit and which ones bleed money. You have to break the numbers down to the level of a single cup before you have any real basis for setting a price.
Step 1: Break Every Ingredient Down to a Per-Cup Cost
List every ingredient that goes into a single cup, then convert each one's purchase price into a per-cup figure based on how much you actually use. A simple three-column table does the job: purchase price, purchase unit, and amount used per cup.
Say you buy beans at ₩30,000 per kilogram and use 18 grams per cup — that works out to ₩540 in beans per cup. If a liter of milk costs ₩2,500 and a latte uses 200ml, that's another ₩500. Add ₩200 for a disposable cup and lid, and the ingredient cost of a latte comes to ₩1,240. Don't skip small-seeming items like syrup, whipped cream, straws, or cup sleeves — those little line items add up and shift the total.
Stopping here only gets you halfway. Rent, labor, utilities, and card processing fees all go out the door a little at a time with every cup sold. Divide your total monthly fixed costs by your projected monthly cup volume to get the fixed-cost share per cup, then add that to your ingredient cost. That sum is the real cost of a single cup at your shop.
Step 2: Add Your Target Margin to Set the Price
Once you know the cost, the price follows a formula: Selling price = cost × (1 + target margin). Take the latte above: a ₩1,240 ingredient cost plus its share of fixed costs brings the per-cup cost to ₩2,400. Set a target margin of 25%, and the selling price comes out to ₩3,000, with a profit of ₩600 per cup. Here's how that flows from ingredient cost to selling price to profit:
Break the cost down, add it back up, multiply by your target margin, and you get both the price and the per-cup profit in one step. The real value of this formula is in running it backward. If you want to price at ₩2,800 to stay competitive with the shop next door, subtract your cost from that price first to see how far your margin actually shrinks. If what's left falls short of your target, the answer isn't to drop the price further — it's to find a way to bring the cost down instead.
Once You Know Your Cost, Price and Profit Line Up
Without knowing your cost, pricing is guesswork and profit is luck. Once you know it, you can see exactly how much each drink earns — and only then can you decide which items to push and which to drop from the menu. A business that actually makes money starts with a structure where every single cup turns a profit.
If pricing strategy is the blueprint, cost management is what translates that blueprint into everyday numbers. Even the best pricing strategy stays just a plan on paper if you miss a rise in bean prices or a creeping increase in milk usage. A cost sheet is a ledger you update every time an ingredient price changes.
A Cost-Accounting Checklist You Can Start Today
Try running the numbers on a single menu item, in this order.
1. List every ingredient in your best-selling drink. 2. Convert each ingredient's purchase price into a per-cup cost based on how much you use. 3. Divide your monthly fixed costs by your projected monthly cup volume and add that share to your cost. 4. Multiply the total cost by your target margin to set a price, then compare it to what you're currently charging. 5. Whenever an ingredient price changes, update your cost sheet and re-check your pricing.
If your current price is lower than what you calculated, you're losing money on every cup right now. If it's higher, that gap is your shop's breathing room. The owner who can state the exact cost of their own cup of coffee, in numbers, is the one who can hold their ground next to the big money moving in.
