While ratio analysis is useful, it also has several limitations. Since ratios are calculated from past financial statements, they reflect historical conditions and may not represent the current or future financial performance of the business. Moreover, ratios can become misleading if the underlying accounting data contains inaccuracies, manipulations or inconsistencies. Another limitation is that ratios do not consider qualitative factors such as management efficiency, economic conditions or market competition. Industry norms also vary widely, making comparisons difficult. Inflation can distort financial values as well, reducing the reliability of ratios over time. Overall, ratios should be used carefully along with other financial and non-financial information for accurate interpretation.
