원가 계산기

Simply enter your ingredient purchase information, and we will automatically calculate the cost ratio for each menu item.

◆ Costs at a Glance
Check the cost ratio, margin, and ingredient proportion for each menu item on a single screen. We will automatically alert you to menu items with high cost ratios.

◆ Easy Ingredient Management
Once ingredients are registered, they are shared across multiple menus. If the purchase price changes, the cost ratio for all connected menus is automatically recalculated.

◆ Price Simulation
"What if the price of coffee beans goes up?", "What if the selling price is raised?" — Check changes in the cost ratio in advance before actual implementation. If you enter your daily sales volume, we will calculate the impact on daily and monthly margins.

◆ Sample Menus by Industry
Cafe, Snack Bar, Chicken, Bakery, Burger — Select an industry, and sample menus and ingredients will be automatically populated so you can start immediately.

◆ Fully Offline Operation
You can use it without an internet connection. All data is stored only on your device and is not transmitted to a server.
