The Operating Income Ratio (OIR) measures a company's operational efficiency by expressing operating income as a percentage of net sales. It indicates how well a company generates profits from its core operations before interest and taxes.

Where:

• \( Operating\ Income \) — Income from core business operations (USD)
• \( Net\ Sales \) — Total revenue after returns and allowances (USD)
