Law firms – like other professional service providers – rely heavily on client satisfaction and service quality to retain key accounts and differentiate from the competition. As such, NPS can be a leading indicator of revenue retention, growth, and brand differentiation in a crowded marketplace.

What is NPS?

Net Promoter® Score (NPS) is a client satisfaction and service quality metric based on a single survey question that asks legal clients how likely they are to recommend your firm to a friend or colleague. Clients respond using a numeric scale of 0-10, ten being extremely likely and zero being not likely at all.

NPS is calculated by subtracting the % of detractors (those who respond with a 6 or lower) from the % of promoters (those who respond with 9 or 10). Click here for a more detailed look at the NPS methodology.

NPS is unique because it offers standardized measurement and reporting on client satisfaction and service quality that can be applied across the legal industry as a whole, at the firm-level, within specific practice areas, even by partner or associate.

Legal Industry NPS in 2018

Law firm NPS is a target topic for Inavero’s annual industry benchmark study, and in 2018 legal clients reported an NPS rating of 19% based on overall satisfaction with their firm (our sample focused on legal clients in the U.S. and Canada).


*Please note, in an effort to round industry benchmarks to whole numbers the NPS calculation may appear off by 1%. For the legal industry, another layer of specificity demonstrates the following: 44.46% (% Promoters) – 25.92% (% Detractors) = 18.54% NPS


Year-over-year data shows that client satisfaction in the legal industry has declined since 2015, when clients rated the industry at 32% NPS. This downward trend, and the relative stabilization of client ratings below 20% NPS, suggest that legal service providers are struggling to meet (and exceed) clients’ service expectations.

For reference, global NPS standards classify 50% NPS as excellent and 70% NPS as world-class. And recognizable service leaders like Nordstrom have an NPS of 75% compared to Comcast, a notorious service laggard, whose clients give them a -1% NPS. Click here to learn more about the NPS methodology.

At 19% NPS, the legal industry benchmark for client satisfaction and service quality is average (at best). Which means that legal firms have a unique opportunity to stand apart from the industry by investing in client satisfaction and service quality.

How does your firm stack up?

If you’re not already leveraging NPS at your firm, we hope you consider this article a call-to-action. Not only do client satisfaction and service quality represent opportunities to differentiate in an increasingly commodified service industry, they are fuel for firm growth.

And if “you can’t manage what you don’t measure” – then you certainly won’t be able to improve it either.
