By applying customized formulas and Excel features, kitchen entrepreneurs can calculate COGS quickly, minimize calculation errors, and produce transparent reports. The implementation method is by providing presentation material to Tofu Factory employees. This solution is expected to provide time efficiency and increase profitability for tofu kitchen entrepreneurs in facing the challenges of market competition. The results obtained provide useful knowledge for tofu factory owners and employees who can understand the application of using Excel in determining HPP practically and simply.
