The National Anti-profiteering Authority (NAA) in India has issued letters to 50 consumer goods companies and over-the-counter drug makers to check if they have passed on the benefits of reduced GST rates to consumers. NAA is questioning the pricing strategies of companies like Mankind Pharma, Johnson & Johnson, and Colgate-Palmolive. Cost-volume-profit (CVP) analysis is an important tool that provides information on the behavior of costs with changes in volume, break-even points, sensitivity of profits to output changes, and profits for projected sales levels. Break-even analysis determines the sales volume needed to cover total costs and is a key aspect of CVP analysis.
