What is the revenue growth rate?

Revenue growth rate measures the percentage increase in revenue between two periods, most commonly year-over-year (YoY). For consulting firms, growth rate indicates market demand, competitive positioning, and execution effectiveness. Healthy growth rates vary by firm stage: early-stage firms may grow 50-100%+ annually while mature firms target 10-20% sustainable growth. Growth must be balanced against profitability and capacity constraints.

Key characteristics

• Calculated as (current period revenue - prior period revenue) ÷ prior period revenue × 100

• Most commonly measured year-over-year to eliminate seasonality

• Early-stage firms often achieve 30%-100%+ growth rates

• Mature consulting firms typically target 10-20% annual growth

• Organic growth is distinguished from acquisition-driven growth

• Must be sustainable given capacity and profitability constraints

Why it matters for service firms

Growth rate determines the trajectory of firm value and founder wealth creation. A $2M firm growing at 20% annually reaches $5M in 5 years. The same firm at 10% growth reaches only $3.2M. For owners planning eventual exits, growth rate directly impacts valuation multiples: firms growing 25%+ often command 2x the multiple of flat firms. However, growth must be profitable and sustainable; unprofitable growth destroys value. The best firms balance healthy growth with strong margins.

Real-world example

Trident Consulting tracks 5-year revenue progression: Year 1 ($1.2M), Year 2 ($1.5M, +25%), Year 3 ($1.65M, +10%), Year 4 ($1.9M, +15%), Year 5 ($2.3M, +21%). Compound annual growth rate (CAGR): 17.7%. The founder analyzes growth sources: 65% from existing client expansion, 35% from new clients. This ratio indicates healthy client relationships, but there is an opportunity to improve new business development. Setting Year 6 target at $2.75M (+20%) requires $450,000 in growth: $290,000 from expansion (historically reliable) and $160,000 from new clients (needs enhanced BD effort). The founder invests in business development resources to support the growth plan.
