SG&A Ratio
The SG&A Ratio expresses selling, general, and administrative expenses as a percentage of revenue, measuring the overhead efficiency of a business and its ability to scale revenues without proportionally increasing fixed-cost infrastructure.
SG&A encompasses all costs not directly tied to production: sales force salaries and commissions, marketing and advertising spend, executive compensation, rent for corporate offices, legal fees, and administrative headcount. In Indian financial reporting, these are typically disclosed as 'other expenses' or 'employee benefits expense' plus 'selling and distribution expenses' in the notes to accounts, requiring some aggregation by analysts.
A declining SG&A ratio as revenues grow is a positive signal — it indicates operating leverage in the cost structure, meaning the business is scaling without needing to add administrative infrastructure proportionally. This pattern was visible in Bajaj Finance during its rapid loan book expansion phase: technology-enabled processes allowed it to onboard customers at declining unit costs, compressing the SG&A ratio and contributing to margin expansion.
Conversely, a rising SG&A ratio in a mature business can signal efficiency deterioration — perhaps a growing management layer, elevated compliance costs, or a marketing-intensive attempt to defend market share. Investors scrutinising Nestle India, for instance, tracked advertising and promotional expenditure as a percentage of net sales carefully, as elevated A&P spending ahead of revenue recovery was a well-known indicator of competitive investment.
For technology companies, SG&A includes the cost of maintaining global delivery centres, sales offices in developed markets, and significant compliance overhead. The ratio in Indian IT majors — Wipro, HCL Technologies, TCS — differed based on the proportion of project-based versus managed-services revenue and the extent of onshore versus offshore delivery, reflecting different client engagement models.
SG&A benchmarking is sector-specific. Consumer staples companies naturally carry higher SG&A than industrial companies because distribution and brand-building are central to their value proposition. Comparing SG&A ratios across sectors is therefore less useful than comparing within a sector over time or against direct peers.
Red flags in SG&A analysis include: sudden jumps in 'other expenses' without revenue growth, elevated related-party service fee payments classified under administrative costs, and large increases in legal and consulting expenses which sometimes presage governance concerns. Indian annual reports often bury granular SG&A disclosures in notes, making forensic reading of those schedules part of rigorous fundamental work.
