2026 Update: Compass, Anywhere, and Century 21
Compass completed its acquisition of Anywhere on January 9, 2026, bringing Century 21, along with brands such as Coldwell Banker, Sotheby’s International Realty, and Corcoran, under Compass International Holdings.
That matters for a Century 21 vs Keller Williams comparison because Century 21 is now part of the broader Compass-owned structure. However, unless agent-facing terms change, the core comparison remains based on how Century 21 and Keller Williams operate for agents today, including commission structure, fees, brand positioning, office model, technology, training, and support.
The acquisition may affect Century 21’s scale, franchise exposure, technology roadmap, debt profile, and long-term strategy over time, but the practical agent-level impact will depend on integration plans, local office decisions, and franchise agreement changes.
Commission Structure
Both brokerages use franchise models where individual offices set specific terms, but the structural frameworks differ significantly. Century 21 offers multiple commission plans with varying caps and royalty structures. Keller Williams uses a standardized cap-based system with a fixed royalty that also caps.
The information below is provided for general comparison purposes only, based on sources available at the time of writing. Any plan summaries, figures, or calculation examples are illustrative only. Agents should verify all current terms directly with the brokerage they are evaluating before making a decision.
Century 21
Century 21 offers multiple fee structures depending on plan tier and franchise location. The two most common are the Kickstart plan for developing agents and the Relentless plan for top producers.
- Commission split: 70/30 to 90/10 (varies by plan tier and production)
- Royalty fee: 6% – 8% per transaction (does NOT cap – continues on every deal all year)
- Commission cap: $22,500 (Kickstart plan); up to $200,000 (Relentless plan)
- Monthly fees: $0 – $350/month (varies by office)
- Transaction fees: $95 – $295 per transaction (separate from royalty)
- E&O insurance: Varies by franchise location
A structural feature of Century 21’s model is the uncapped royalty. After the commission cap is reached, the 6–8% royalty continues applying to every transaction. At $500K GCI, that royalty represents $30,000 to $40,000 in annual costs. The Relentless plan’s $200K cap is a high enough threshold that few agents reach it within an anniversary year.
Keller Williams Commission Structure
Keller Williams uses a capped structure for both the split and the royalty. Once both caps are reached, agents pay only fixed monthly and per-transaction fees for the remainder of the anniversary year.
- Commission split: 70/30 baseline (varies by market center, negotiable)
- Royalty fee: 6% per transaction, capped at $3,000 per year
- Commission cap: $15,000 – $36,000+ (varies by market center)
- Monthly fees: $60 – $125+/month (desk + technology fees)
- Transaction fees: $50 – $399 per transaction (varies by office)
- E&O insurance: $122 – $350/month
Both the commission split and the royalty cap at Keller Williams. After the $22K cap (mid-range example) and the $3K royalty cap are reached, agents earn 100% commission with only fixed monthly fees and per-transaction charges remaining. At Century 21, the royalty does not cap and continues to apply on every transaction.
Keller Williams Profit Share Program
Keller Williams operates a profit share program that distributes a portion of market center profits to agents who recruit other agents. Century 21 does not offer an equivalent program.
KW distributes 48% of each market center’s profits to agents who have recruited other productive agents. The program works through 7 levels:
- Level 1: A portion of market center profits generated by agents personally recruited
- Levels 2–7: Decreasing percentages from agents recruited by your recruits, down seven generations
- Vesting: Full vesting after 7 years of participation
- Willable: Once vested, profit share becomes a willable asset
Most KW agents with limited recruiting activity earn modest monthly amounts from profit share, while agents who systematically build and maintain large downlines over years generate substantially higher annual amounts. After vesting, profit share continues to generate income separate from active sales activity.
Profit share aligns with agents who actively recruit and mentor; for agents who focus exclusively on personal production, the program may have limited weight in the brokerage decision.
Century 21 offers no revenue sharing, profit sharing, or agent attraction incentive. Income at Century 21 is tied to personal production.

Head-to-Head: $250K GCI Comparison
At $250,000 in gross commission income:
- Century 21: ~$47,125 in total costs – the agent keeps ~$202,875 (81%)
- Keller Williams: ~$30,730 in total costs – the agent keeps ~$219,270 (88%)
KW agents keep roughly $16,400 more per year at this production level. The difference is driven primarily by C21’s uncapped royalty fee – at $250K GCI, that royalty costs $17,500 at C21 versus just $3,000 (capped) at KW.
The cost differential widens at higher production. At $500K GCI, the KW example shows roughly $34,500 lower total brokerage cost. Profit share, where applicable, would represent additional KW-side compensation not present in the Century 21 model.
At lower production levels ($100K GCI), the difference narrows to approximately $5,500 because the uncapped royalty has fewer transactions to apply against.
Training and Professional Development
Century 21 Training
Century 21 provides training through C21 University, an online learning platform with courses covering the fundamentals of real estate sales, marketing, and business development.
C21 University covers new agent onboarding, listing presentations, buyer consultations, technology adoption, and social media marketing. The corporate brand also provides ongoing webinars and regional training events.
The quality of training at Century 21 varies significantly by franchise. Some offices invest in local coaching programs, mentorship, and accountability groups. Others provide minimal support beyond what’s available online. Century 21’s training operates primarily through C21 University and franchise-level resources.
Keller Williams Training
Keller Williams was founded with a heavy emphasis on agent education, and the training infrastructure includes:
- Ignite: Comprehensive free training program for new agents
- BOLD: Intensive mindset and lead generation program (~$800)
- KW MAPS Coaching: Personalized one-on-one coaching (additional cost, various tiers)
- KW Connect: Online learning platform with hundreds of courses
- Market center training: Regular local classes, mastermind groups, and peer accountability
- Family Reunion / Mega Camp: Annual national events with top producers and industry speakers
KW’s training includes a business philosophy rooted in Gary Keller’s books. “The Millionaire Real Estate Agent” provides the framework used across all KW training: lead generation, time management, leverage through systems, and structured business development.
The two brokerages structure training differently in terms of scale and integration. Most KW core training is included in market center fees; specialized programs such as BOLD carry additional cost. Century 21’s training is delivered through C21 University and franchise-level resources.
Technology and Tools
Century 21 Technology
Century 21 provides a core set of technology tools through its franchise system:
- Zap (Moxi Works): CRM and marketing automation platform
- C21 Brand marketing suite: Templates, social media content, listing marketing
- Agent website platform: Template-based personal websites
- Listing syndication: Distribution to major real estate portals
- AI-powered tools: Listing descriptions and marketing copy generation
Century 21’s tools cover the standard franchise feature set. The Moxi Works partnership provides the CRM foundation. Many C21 agents supplement with third-party tools for specific functions such as email marketing and lead generation.
Keller Williams Technology
Keller Williams operates a proprietary technology platform built around Command:
- Command: Comprehensive platform combining CRM, marketing, lead generation, and transaction management
- KW App: Consumer-facing home search application
- SmartPlans: Automated marketing campaigns and follow-up sequences
- Designs: Marketing material creation with KW branding
- Opportunities: Lead routing and pipeline management
- Referrals: Internal referral management system
Keller Williams’ technology approach centers on Command as an all-in-one platform spanning CRM, marketing, lead generation, and transaction management. Command is comprehensive in scope; agent feedback varies on individual module quality compared to best-in-class standalone products. Some agents adopt the full ecosystem; others supplement with third-party tools.
The technology fee is included in monthly KW costs; agents pay for Command regardless of usage level. Agents who adopt the full ecosystem may save on third-party subscriptions.
Neither brokerage’s technology is considered industry-leading. Both provide adequate tools with room for improvement.
Culture and Work Environment
Century 21 Culture
Century 21’s culture is defined by accessibility and broad appeal. The brand is welcoming to agents at all experience levels, from brand-new licensees to seasoned veterans. Office culture varies by franchise, but common threads include:
- Practical, results-oriented environment
- Less formal than luxury-positioned brands
- Strong consumer brand recognition that agents can leverage
- Focus on community and local market expertise
The “Relentless” rebrand has introduced a more performance-focused element to C21 culture, particularly in offices that have adopted the newer commission plans. Overall, C21 remains one of the more approachable, middle-of-the-road cultures in real estate.
Keller Williams Culture
Keller Williams culture is distinctive and intentional. Built on the motto “God, family, then business,” KW creates an environment that blends personal development with professional growth. Key cultural elements:
- Education-first mentality – learning is valued and incentivized
- Recruiting is part of the culture (aligned with profit share)
- Agents share scripts, strategies, and best practices openly
- Entrepreneurial mindset – building a business, not just doing a job
- High-energy market centers with regular events and accountability groups
The profit share model creates a particular cultural dynamic. Because agents earn financial returns when their recruits succeed, there is a financial incentive to help new agents grow. Recruiting conversations are common at KW market centers.
KW culture tends to attract agents oriented toward personal development, systems thinking, and long-term wealth-building approaches.
Brand Recognition and Market Presence
Century 21 Brand
Century 21 has high consumer brand recognition across U.S. markets, supported by decades of national TV advertising. The gold jacket and logo are widely recognized cultural elements in American real estate.
C21 operates 14,000+ offices across 86 countries and territories, making it one of the most geographically diverse real estate brands in the world. That global reach provides referral opportunities for agents who serve relocating clients.
The brand has worked to update its visual identity with a refresh and the “Relentless” campaign, moving from the historical gold-and-brown aesthetic toward a more contemporary visual style.
Keller Williams Brand
Keller Williams is the world’s largest real estate franchise by agent count, with 180,000+ agents across 1,100+ offices. The red KW signs are present in most American markets.
KW’s brand recognition is strong but different from C21’s. While C21 is known to virtually every consumer, KW is better known among real estate professionals and active buyers/sellers. KW’s brand is associated with agent training and professionalism rather than consumer-facing prestige.
Within the industry, KW has strong brand recognition. Being a “KW agent” is associated with the company’s training infrastructure. Among consumers, the brand is widely recognized but does not carry the same scale of decades-long consumer advertising as Century 21.
In practice, most real estate transactions are won on agent reputation and relationship, not brokerage brand. Neither brand provides a decisive competitive advantage in the average listing presentation.
Agent Support
Century 21 Agent Support
Support at Century 21 is delivered primarily at the franchise office level. The managing broker and office staff handle day-to-day questions, transaction support, and technology assistance.
C21 does not offer 24/7 support as a corporate standard. Support quality varies by office – larger franchises may have dedicated transaction coordinators and marketing staff, while smaller offices operate lean.
Corporate support focuses on brand resources, marketing materials, and technology platform maintenance rather than direct agent assistance.
Keller Williams Agent Support
KW market centers typically have a team leader, market center administrator, and in larger locations, additional support staff. The structure is more standardized than C21’s franchise-by-franchise approach.
KW does not offer 24/7 support. The community-driven culture provides informal support through peer relationships. Team leader compensation is tied to market center profitability, which is in turn tied to agent production.
The aligned-incentive structure at KW links team leader compensation to market center profitability, which is in turn tied to agent production. This creates a direct financial alignment between team leader and agent outcomes, with implementation varying across market centers.
Agent Profiles That Align with Century 21’s Model
Century 21’s structure tends to align with agents who:
- Want strong consumer brand recognition – C21’s name recognition among the general public is high across U.S. markets
- Prefer a culture with less recruiting emphasis than KW’s profit-share-driven approach
- Want a commission cap structure outside of KW’s culture model – C21’s Kickstart plan caps at $22.5K with the uncapped royalty applying separately
- Serve international or relocating clients and use C21’s 86-country office network
- Operate independently and prefer brand support without a community-heavy, event-driven office environment
- Identify a specific C21 office with managing broker and culture aligned with their working style
Agent Profiles That Align with Keller Williams’ Model
Keller Williams’ structure tends to align with agents who:
- Value KW’s education ecosystem, which includes Ignite, BOLD, MAPS Coaching, and KW Connect
- Prioritize lower brokerage costs at higher production levels through KW’s capped split and capped royalty
- Pursue passive income potential through the profit-share program by recruiting and mentoring other agents
- Operate within community-driven environments with regular training, events, and peer accountability
- Are newer agents seeking structured training, scripts, and systems at the launch stage
- Approach real estate with an entrepreneurial orientation and value a culture focused on business development
- Value long-term wealth building — profit share vests at seven years and becomes a willable asset
What Agents Also Ask
How does Century 21’s commission cap differ from Keller Williams’?
Both brokerages cap the commission split portion. The structural difference is in the royalty fee. Keller Williams caps its royalty at $3,000 per year. Century 21’s 6–8% royalty does not cap and continues to apply on every transaction throughout the anniversary year.
What plan tiers does Century 21 offer?
Century 21 offers multiple plan tiers depending on franchise location. The two most commonly referenced are the Kickstart plan, designed for developing agents with a $22,500 cap, and the Relentless plan for higher producers, with a cap that extends up to $200,000.
How does Keller Williams’ profit share work in practice?
Keller Williams distributes 48% of each market center’s profits to recruiting agents across seven levels. Vesting occurs after seven years of continuous participation, after which profit share becomes a willable asset. Income amounts depend on the size and productivity of an agent’s recruited downline.

Century 21 operates 14,000+ offices across 86 countries and territories, providing extensive international referral coverage. Keller Williams has international operations as well but at smaller scale, with the majority of its 1,100+ offices in the United States. Century 21’s international footprint is the larger of the two.

Century 21 Pros and Cons
The points below cover structural realities of the Century 21 model as it operates for agents today. Individual franchise quality, local management, and market conditions will shape your day-to-day experience within those structures.
Century 21 Pros
- Established global brand with a large referral network. Century 21 operates 14,000+ offices globally. For agents serving relocation-heavy markets, that footprint generates inbound referrals from other Century 21 offices – volume that a smaller or independent franchise network typically cannot match.
- Multiple plan tiers give production-based flexibility. The Kickstart plan (70/30 split, $22,500 cap) is designed for developing agents. The Relentless plan (90/10 split, up to $200,000 cap) suits higher producers. Agents are not locked into a single fee structure regardless of their production level.
- Structured training through C21 University. Century 21 offers an online learning platform with courses covering sales fundamentals, negotiation, marketing, and business development. NAR-accredited certification courses are available through the program, and new agent onboarding follows a documented structure rather than being left to individual office discretion.
- Non-competing broker model. Century 21 franchisees are not permitted to compete directly with their own agents for listings, which removes one common tension point in traditional franchise relationships.
- Consumer brand recognition lowers the credibility gap. In markets where clients are less familiar with an agent personally, the Century 21 name provides an immediate trust signal. For agents building a client base from scratch, operating under a nationally recognized brand can reduce initial friction in client conversations.
Century 21 Cons
- The royalty fee does not cap. At 6% to 8% per transaction, the royalty continues applying to every deal all year. At $250,000 GCI, the royalty in the worked examples above costs $17,500 per year at the 7% example rate. At $500,000 GCI, that cost ranges from $30,000 to $40,000. Keller Williams caps the same fee at $3,000 per year. This uncapped royalty is the primary driver of the cost difference between the two brokerages at mid-to-high production levels.
- Significant franchise variability. Commission splits, monthly fees, desk fees, and management quality all differ by franchise location. Two agents at different Century 21 offices can have entirely different economic arrangements. There is no single uniform Century 21 deal – the terms you receive depend on the local franchisee.
- No profit share or revenue share program. Century 21 does not offer agents any participation in the economics of recruiting. All income is tied to personal production. Agents who want a non-production income component must build it entirely outside of Century 21.
- Technology is fragmented across multiple platforms. Rather than a single integrated stack, agents work across 21Online, the Zap lead-generation system, and the Design Center for marketing assets. Agents moving between these tools report multiple logins and inconsistent data flow between systems.
- High-volume producers face rising royalty costs with no ceiling. Because the royalty does not cap, every additional transaction above the commission cap adds royalty cost. The difference in total brokerage cost between Century 21 and Keller Williams at $500,000 GCI is approximately $34,500 per year in the worked examples on this page, driven almost entirely by the uncapped royalty.
Bottom Line: Century 21 vs Keller Williams
Century 21 makes the strongest case for agents who prioritize consumer brand recognition, want access to a global relocation referral network, or are early in their career and benefit from plan-tier flexibility and C21 University’s structured training. The brand name travels across markets, and the Kickstart-to-Relentless plan progression gives newer agents a clear path as production increases.
For mid-to-high-volume producers, the economics favor Keller Williams in most scenarios. The capped royalty is the decisive factor: once the $3,000 KW royalty cap is hit, every additional deal costs nothing in royalty fees for the remainder of the year. At $250,000 GCI, the total brokerage cost difference in the worked examples above is approximately $16,400 per year in favor of KW. At $500,000 GCI, that gap reaches roughly $34,500. The KW profit share program adds a further economic dimension that Century 21 does not offer.
Agents evaluating options beyond these two should review the full brokerage comparisons library or the eXp Realty vs Keller Williams comparison for a model that layers revenue share and equity participation on top of the capped-fee framework.
