The Production Price shown at the top of the editor and in the price card is the sum, for the selected portion, of each ingredient's cost × quantity ÷ the ingredient's per each amount. It updates live as you change quantities. Profit is the selling price minus that cost, and the card lists suggested selling prices at 20 / 25 / 30 / 35 % margins plus a Custom Margin box. With several portions, click the small list icon next to the production price to open Production Price by Portion (selling price, production price, profit and %).

If you turn on Manually Override Production Price and enter a Manual Production Price for a portion, that value replaces the calculated cost for that portion. The admin list also colours each portion's margin green / grey / red.
