What is the main benefit of following the matching principle in accounting?

The main benefit of following the matching principle in accounting is to align revenues with the expenses that brought them. This principle ensures that revenues are recorded in the same accounting period as the expenses incurred to generate those revenues. By doing so, it provides a more accurate picture of a company's financial performance within a specific period. This alignment helps in assessing how effectively a business is generating profit and managing its costs, thus offering clearer insights into operational efficiency and overall profitability. By presenting financial statements that reflect the true relationship between revenues and expenses, stakeholders—including management, investors, and creditors—can make more informed decisions based on realistic financial data.
