Agency Statistics & Benchmarks

Client retention statistics for agencies (2026)

In a 2025 benchmark of 300+ agencies, 8-figure agencies kept 92% of their clients each year and 7-figure agencies kept 78%. These client retention statistics cover agency and professional-services retention rates, the cost of replacing a client, client lifetime value and what the research says about loyalty. Each figure links to its source.

Key Takeaways

What is a good client retention rate for an agency?

For an established agency, 85% or more a year is in line with consulting and IT services firms, and the larger agencies in Predictable Profits’ sample reached 92%. Below 80%, you are replacing a fifth of your client base every year. Use our agency churn calculator to check your own rate.

85% / 83%

Average annual retention for business consulting and for IT and managed services firms. First Page Sage aggregates 14 secondary sources covering 10,214 firms (January 2023 to March 2025), so treat these as rough ranges.

82%

Average annual retention for software development firms, close to what development agencies can expect on ongoing work.

55-86%

Range of average annual retention across the 21 industries First Page Sage tracks, from hotels and hospitality (55%) to commercial insurance (86%). An earlier version of this page cited a 75-90% range (10-25% annual loss) that the current report no longer gives.

70.7%

Share of professional services revenue that came from existing clients in 2024 (57.9% from existing services and 12.8% from new services sold to them), up from 68.7% in 2023. SPI also found 70.1% of clients were willing to act as references. This replaces an 84% professional-services retention rate and a 65% existing-customer revenue share that could not be found in the sources cited earlier.

88%

Of digital agencies offer both projects and retainers; 91% offer retainers. Retention means something different for each: renewal for retainers, repeat projects for project clients.

How much does losing a client cost?

Replacing a client costs more than keeping one because new business needs sales time, proposals and onboarding. For example, an agency with 20 clients on $4,000 monthly retainers ($960,000 a year) loses about 4.4 clients a year at 78% retention, or roughly $211,000 in annual revenue to replace. At 92% retention it loses about 1.6 clients, or $77,000.

5-25x

Acquiring a new customer is five to 25 times more expensive than retaining an existing one, depending on the study and the industry. This is a widely cited range, not a precise agency figure.

Profit increase from a 5% increase in customer retention, from research by Frederick Reichheld of Bain & Company, who created the Net Promoter Score.

7%

Average share of revenue digital agencies spend on sales and marketing. Every lost client has to be replaced from this budget, mostly through referrals.

Loyalty leaders, companies at the top of their industry in Net Promoter Score or satisfaction for three or more years, grow revenue more than twice as fast as industry peers.

60-70% vs 5-20%

Probability of selling to an existing customer compared with a new prospect. Invesp attributes the figure to the book Marketing Metrics. It is an old, general-business estimate, not agency data, and the live Invesp page no longer shows it, so the link points to an archived copy from January 2024.

67%

More spent by the average repeat customer of online apparel retailers in months 31-36 of the relationship than in months 0-6 (23% more in groceries). This is retail data from 2000, included to show that spend per customer tends to grow with tenure. An earlier version of this page credited the figure to Shopify.

$5,475

Average cost per hire for a non-executive role in the US. This measures hiring, not client acquisition: it is the cost of replacing an account manager who leaves, which often puts the client relationship at risk too. An earlier version of this page cited $4,700 from older SHRM data.

Client lifetime value at agencies

Lifetime value connects retention to revenue: the longer a client stays, the more each acquisition pays back. Estimate yours with the client lifetime value calculator, and track renewals and upsells in your CRM.

$450K / 36 mo

Average client lifetime value at 8-figure agencies, over an average relationship of 36 months.

Source: Predictable Profits, 2025 Agency Growth Benchmark

$125K / 18 mo

Average client lifetime value at 7-figure agencies, over an average relationship of 18 months. Doubling tenure matters as much as raising fees.

Source: Predictable Profits, 2025 Agency Growth Benchmark

24% / 16%

Fast-growing agencies completed 24% more projects and served 16% fewer retainer clients than average. Promethean’s reading: recurring revenue gives a stable base, but growth came from new project work.

What keeps agency clients?

Public data on why agency clients leave is thin. The consistent themes are structured onboarding, a stable account team and regular proof of results. A client portal gives clients one place to see work, approvals and invoices. Our communication best practices and client retention strategies guides cover the habits behind these numbers.

Onboarding

Predictable Profits attributes the 92% vs 78% retention gap mainly to stronger onboarding processes and dedicated client success teams at 8-figure agencies.

42%

Of employees who quit say their manager or organization could have prevented it. This is staff turnover, not client churn, but losing the account manager a client trusts is a common trigger for an agency review.

Source: Gallup (July 2024)

75%

At least 75% of the reasons for voluntary employee turnover can be influenced by managers, based on a Gallup meta-analysis of 44 organizations, Gallup polls and exit interviews. This is older staff-turnover research; the 2024 Gallup figure above (42% preventable) measures what leavers themselves say.

77% / 36%

Of employees who quit, 77% left within three months of starting to look or did not search at all, and 36% did not talk to anyone before deciding to resign. Again this is staff data: account team departures happen fast and with little warning, so client relationships should not depend on one person.

73% / 70%

73% of B2B decision-makers say thought leadership is a more trustworthy basis for judging a firm’s capabilities than its marketing materials, and more than 75% say it led them to research a product or service they had not considered. 70% of C-suite leaders say a piece of thought leadership made them question whether to keep working with an existing supplier, which cuts both ways for agencies.

About these statistics

  • AgencyPro did not survey agencies for this page and has no original retention data of its own. Every figure is secondary: it summarizes published third-party research and links each figure to its source. The worked revenue example and section introductions are AgencyPro commentary.
  • Original research cited here: Predictable Profits (agency benchmark), SPI Research (professional services survey), Promethean Research (agency surveys), Gallup and SHRM (employer and employee data), Edelman-LinkedIn (3,484 executives) and the Bain and Mainspring retail study (2000). Secondary compilations: First Page Sage (an aggregation of other sources), Harvard Business Review (2014, summarizing earlier studies including Bain’s) and Invesp (2015, citing the book Marketing Metrics). Staff-turnover figures describe employees, not clients, and are labeled on each card.
  • Agency-specific retention figures come from Predictable Profits, an agency coaching firm whose 2025 benchmark covers 300+ 7- and 8-figure agencies and does not publish field dates or sampling. First Page Sage figures are an aggregation of secondary sources.
  • Figures were re-checked against their sources in October 2026. Employee-turnover figures from Gallup are kept and labeled as staff data, not client churn. Where a cited source no longer contained a figure (an 84% professional-services retention rate, Shopify’s 65% and 67% repeat-customer figures, a 75-90% retention range), it was replaced with the current figure for the same measure from First Page Sage or SPI Research. A second check in October 2026 restored three figures with their original sources: the 60-70% vs 5-20% selling probability (from an archived copy of the Invesp page), the 67% repeat-customer spend figure (Bain & Company, 2000, previously credited to Shopify) and Gallup’s 75% manager-influence finding (2008). An 80/20 revenue split attributed to HBR could not be verified in any published source and is not shown.
