Comparing a R50 million company to a R5 billion one seems pointless until you convert everything to percentages. Common-size analysis strips out the scale differences and shows you the underlying economics of how businesses operate.
You'll learn to create common-size income statements where every line item becomes a percentage of revenue, and common-size balance sheets where everything's a percentage of total assets. Suddenly you can see that two companies in the same industry have completely different cost structures, or that one carries way more inventory relative to sales than its competitors.
Patterns emerge quickly
This technique reveals things absolute numbers hide. A company growing revenue by twenty percent sounds impressive until common-size analysis shows gross margin compressed from 42% to 38%—they're buying growth by cutting prices. Another company might show stable revenue but SG&A expenses creeping from 18% to 23% of sales, eroding profitability.
We cover both vertical analysis, comparing line items within a single period, and horizontal analysis, tracking percentage changes across time periods. You'll practice identifying which metrics matter for different business models and industries.
The course includes extensive work with retail, manufacturing, and service companies because their common-size profiles look completely different. Retailers typically show thin margins with high inventory turnover. Software companies have gross margins above 80% but heavy R&D spending. Understanding these patterns helps you spot outliers and anomalies.
Industry benchmark databases
You'll learn to use Risk Management Association and other sources for industry-standard ratios
By the end, you can take any set of financial statements and quickly assess whether the company's cost structure, asset base, and capital allocation align with industry norms or deviate significantly.
