Name: Net Profit Margin

Definition: Net profit margin shows how much profit remains after paying all costs — including operating expenses, interest, and taxes — for every dollar of sales. A higher margin means the business is efficient and keeps more of its sales as bottom-line profit. Falling margins may signal rising costs or pricing pressure.
