Revenue growth measures the percentage change in a company's trailing twelve-month revenue compared to [1 year / 3 years / 5 years] ago. It is the most fundamental growth metric and answers the basic question of whether the company's top line is expanding, contracting, or stagnating.
One-year revenue growth captures the most recent trend and is useful for identifying inflection points — accelerating or decelerating growth. Three-year growth provides a medium-term view that smooths out single-year anomalies and reveals whether the growth trajectory is sustainable. Five-year growth provides a long-term perspective that captures full business cycles and reveals the structural growth rate of the business.
Revenue growth should always be evaluated alongside margin trends. A company growing revenue at 20% but seeing margins compress may be buying growth at the expense of profitability. A company growing revenue at 8% with expanding margins may be creating more shareholder value.
