1. What is Financial Ratio Analysis?

Financial Ratio Analysis is a structured, quantitative method used to evaluate a company’s financial condition and performance by analysing data from its financial statements. These statements include:

The objective of ratio analysis is to convert raw financial data into useful metrics that provide insight into the operational efficiency, profitability, liquidity, and financial health of a company. It supports stakeholders in decision-making—from investors and lenders to internal management.

Example: Profitability Ratio – Net Profit Margin

Formula:
Net Profit Margin = (Net Profit / Revenue) × 100

Interpretation:
If a company has ₹10 crore in revenue and ₹1 crore in net profit:
Net Profit Margin = (1 / 10) × 100 = 10%
This means for every ₹100 earned, ₹10 is kept as net income. A higher margin shows better profitability.

Final Thoughts

Financial ratio analysis is a foundational pillar of corporate finance and investment decision-making. While it doesn’t provide the full picture alone, when combined with qualitative analysis, it becomes a powerful lens through which a company’s financial story can be understood.
