Quarterly Revenue Growth

Quarterly revenue growth measures the percentage change in a company's revenue compared to the same quarter one year ago. This year-over-year comparison eliminates seasonal distortions, providing a clear view of whether the business is expanding, contracting, or maintaining its scale. Revenue growth is often considered the most fundamental indicator of business health.

The calculation:

Quarterly Revenue Growth = (Current Quarter Revenue - Same Quarter Last Year) / Same Quarter Last Year × 100

For example, if Q3 revenue this year is $2.5 billion versus $2.0 billion in Q3 last year, quarterly revenue growth is 25%.

Interpreting growth rates:

<ul>

30%+ growth: Exceptional; typical of high-growth tech or emerging companies

15-30% growth: Strong growth; often commands premium valuations

5-15% growth: Moderate; solid for mature companies

0-5% growth: Slow growth; may indicate market saturation

Negative growth: Contraction; requires investigation of causes

Why quarterly growth matters:

• Timeliness: More current than annual figures; captures recent momentum
• Trend identification: Sequential quarters reveal acceleration or deceleration
• Expectation setting: Analysts use growth rates to project future performance
• Valuation driver: Growth companies are valued on revenue trajectory

Important caveats:

• Easy comparisons: Growth looks artificially high if the prior year quarter was weak
• Acquisition effects: M&A can inflate growth without organic expansion
• Currency impact: International companies may see growth distorted by exchange rates
• One-time items: Large contracts or accounting changes can skew single quarters

Evaluate growth in context. Compare to industry peers, consider the company's size (smaller companies typically grow faster), and examine whether growth is organic or acquisition-driven. Sustainable growth matters more than one exceptional quarter.
