What is annual recurring revenue?

Annual recurring revenue is the annualized value of recurring contracts, calculated as MRR multiplied by 12. ARR provides the clearest picture of a consulting firm's stable revenue base and is the primary metric used in firm valuations for recurring revenue businesses. Growth in ARR indicates successful expansion of retainer relationships and improved revenue quality.

Key characteristics

• Calculated as MRR × 12 for current run rate

• Also calculated as the sum of annual contract values for all recurring agreements

• Primary valuation metric for recurring revenue consulting firms

• Tracked alongside ARR growth rate (year-over-year change)

• Excludes non-recurring project revenue and one-time fees

• High-growth consulting firms target 30-50% annual ARR growth

Why it matters for service firms

ARR is the metric that determines the valuation of consulting firms for recurring revenue businesses. A firm with $1M ARR might sell for $2-3M (2-3x ARR), while a firm with $1M in unpredictable project revenue might only command $500,000-$800,000 (0.5-0.8x). ARR growth rate further influences multiples: firms growing ARR at 40%+ command 4-6x multiples. For founders, understanding the relationship between ARR and valuation provides a clear incentive to convert project revenue to recurring models where possible.

Real-world example

Momentum Consulting has $95,000 MRR from 14 retainer clients, yielding $1.14M ARR. Project revenue adds another $800,000 annually, bringing the total revenue to $1.94M. Two years later, after focused effort on retainer conversion, MRR grows to $165,000 ($1.98M ARR) while project revenue holds at $750,000. Total revenue is $2.73M. When the founder receives acquisition offers, the improved revenue mix dramatically impacts valuation. The $1.98M ARR component values at 2.5x ($4.95M) while project revenue values at 0.7x ($525,000), for a total enterprise value of $5.48M versus approximately $2.5M the original revenue mix would have commanded.
