Once you have collected and allocated your costs, you need to analyze and interpret your data to generate meaningful insights and recommendations. You should use appropriate techniques and tools to organize, visualize, and summarize your data and highlight the key findings and trends. For example, you can use charts, graphs, tables, dashboards, and reports to present your data in a clear and concise way. You should also use relevant ratios, metrics, and benchmarks to evaluate your data and compare it with your goals, standards, or industry averages. For example, you can use the contribution margin ratio, the break-even point, the return on investment, or the cost-volume-profit analysis to assess your profitability and efficiency.
