Definition

Client retention rate measures the percentage of clients who continue working with a firm over a defined period. It's calculated by dividing the number of clients at the end of a period (minus new clients acquired) by the number of clients at the start, then multiplying by 100.

Why This Matters for Professional Services Firms

For professional services firms, retention rate is a critical metric that directly impacts revenue stability and growth. Industry benchmarks suggest healthy firms maintain 80-90% annual retention rates. Improving retention by just 5% can increase profits by 25-95%.

Formula

((Clients at End - New Clients) / Clients at Start) × 100
Clients at End:Total clients at period end
New Clients:Clients acquired during the period
Clients at Start:Total clients at period start
