Are you spending thousands on marketing staff without seeing the returns you expected?
Does your business need senior marketing expertise but can't justify the six-figure salaries?
Are you caught between building a full team and outsourcing everything, unsure which path actually delivers results?
If you're struggling to balance cost, expertise, and scalability in your marketing team, you're not alone. As a Fractional Marketing Director who's helped dozens of businesses navigate this exact decision, I'll show you exactly when to choose in-house, when to go fractional, and how to maximize ROI in either model.
By the end of this article, you'll know which marketing structure delivers stronger ROI at your revenue stage, and how to choose with confidence.
Full transparency: I deliver fractional marketing services, so I naturally bring perspective from that side. But this article is designed to give you a balanced, numbers-based framework to help you make the best decision for your business, whether that's fractional, in-house, or hybrid.
In-house marketing teams are full-time employees dedicated exclusively to one company, while fractional marketing teams are senior-level professionals who work with multiple clients on a part-time or project basis.
This fundamental structural difference affects everything from cost and commitment to expertise accessibility and strategic flexibility.
An in-house marketer sits at your office (or joins your Zoom calls) every single day. They know your brand inside out, attend all your meetings, and focus 100% of their working hours on your business.
A fractional marketer works with you for agreed hours each week or month. You might get 10, 20, or 30 hours of their time rather than a full 40-hour week. They bring experience from working across multiple businesses and industries.
The trade-off is between exclusive dedication and cost-efficient expertise. You pay more for full-time attention, but less for focused strategic input.
A full in-house marketing team of 3-5 professionals typically costs between £250,000-£500,000 ($312,500-$625,000) annually when factoring in salaries, benefits, software, and overhead, while a comparable fractional team ranges from £60,000-£180,000 ($75,000-$225,000) per year.
The cost differential becomes even more pronounced for small to mid-sized businesses that need senior-level expertise but can't justify multiple six-figure salaries.
Here's what those numbers actually include:
| Cost Category | In-House Team (3-5 people) | Fractional Team |
|---|---|---|
| Base salaries | £150,000-£300,000 ($187,500-$375,000) | £48,000-£120,000 ($60,000-$150,000) |
| Benefits & taxes | £40,000-£80,000 ($50,000-$100,000) | £0 (contractor) |
| Office space | £15,000-£25,000 ($18,750-$31,250) | £0 |
| Software & tools | £10,000-£20,000 ($12,500-$25,000) | £5,000-£10,000 ($6,250-$12,500) |
| Recruitment | £15,000-£30,000 ($18,750-$37,500) | £0 |
| Training | £10,000-£20,000 ($12,500-$25,000) | £0 |
| Management time | £10,000-£25,000 ($12,500-$31,250) | £7,000-£15,000 ($8,750-$18,750) |
| Total Annual Cost | £250,000-£500,000 ($312,500-$625,000) | £60,000-£145,000 ($75,000-$181,250) |
You're looking at 60-70% cost savings with fractional support. That difference represents money you can invest in advertising, product development, or simply keep as profit.
Bear in mind these figures assume you need continuous marketing support. The gap narrows if you already have some team members in place.

In-house teams offer unmatched brand immersion, immediate availability, and deep institutional knowledge that comes from working exclusively within one company culture and market position.
This dedicated focus allows in-house marketers to develop nuanced understanding of customer personas, product details, and internal processes that can take external teams months to acquire.
Here's what makes in-house teams powerful:
For businesses with complex products or highly specialised markets, this depth of knowledge can't be easily replicated. An in-house team member who's spent 18 months learning your technology stack brings value that's hard to measure but easy to feel.
Fractional marketing teams provide immediate access to senior-level strategists with cross-industry experience at a fraction of the cost of full-time hires, while offering exceptional scalability and reduced financial risk.
Companies can essentially 'rent' a CMO, content strategist, and paid ads specialist for the exact number of hours needed each month, rather than paying for 40 hours per week regardless of workload.
The advantages stack up quickly:
A Fractional Marketing Director often handles everything from content creation to CRM management, providing broad coverage without full-time costs.
In-house teams typically deliver superior ROI when a company has consistent, high-volume marketing needs, requires constant real-time collaboration across departments, or operates in a highly specialized or regulated industry.
Organisations with annual revenues exceeding £10-20 million ($12.5-$25 million) and established product-market fit often reach the inflection point where dedicated internal resources become more cost-effective than external support.
You'll see better returns from in-house teams when:
Your marketing volume justifies full-time roles. If you're publishing daily content, running multiple ad campaigns simultaneously, and managing complex automation sequences, you need people working on this 40 hours a week.
Integration is critical. Companies where marketing needs to constantly coordinate with product development, customer success, and sales benefit from having marketers in every conversation.
Specialisation matters deeply. Financial services, healthcare, or technical B2B companies with lengthy sales cycles often need marketers who spend months understanding compliance requirements and technical specifications.
You're building long-term brand assets. When your strategy focuses on building thought leadership, community, and multi-year content programs, the continuity of in-house teams pays dividends.
Fractional teams excel for startups, scale-ups, and mid-sized companies that need strategic leadership and specialized execution but lack the budget or workload to justify multiple full-time senior hires.
They're particularly valuable during transitional periods, such as launching new products, entering new markets, or rebuilding after a marketing leadership gap; when companies need expertise fast without long-term commitment.
Fractional support delivers better value when:
You need strategy more than volume. If your problem is "we don't know what to do" rather than "we can't execute fast enough," you need senior strategic thinking, not junior executors.
Budget constraints are real. When you're choosing between hiring one mid-level marketer or accessing three senior specialists fractionally, the math often favors fractional.
Your needs fluctuate. Seasonal businesses, project-based companies, or those in rapid growth phases benefit from flexible support that scales with demand.
You're filling a gap. Lost your marketing director? Need coverage while you recruit? Fractional support keeps momentum going without rushing hiring decisions.
You want to test before committing. Not sure if you need a full-time CMO? Work with a fractional one first. You'll learn exactly what that role should look like for your business.
As your Fractional CMO, I provide strategic guidance to align your marketing team around building customer relationships and driving growth, giving you leadership without the six-figure salary commitment.
A hybrid model combining core in-house team members with fractional specialists often delivers the best of both worlds, providing brand continuity while accessing specialized skills as needed.
Many growing companies employ 1-2 full-time marketers to handle daily operations and brand stewardship, then augment with fractional experts for strategy, specialized channels like SEO or paid media, or overflow capacity during launches.
This hybrid approach typically looks like:
The hybrid model gives you consistency where it matters and flexibility where it helps. Your in-house team maintains brand voice and handles urgent requests, while fractional specialists bring expertise and strategy when you need it.
This structure works brilliantly for companies in the £2-10 million ($2.5-$12.5 million) revenue range. You get enough internal capacity to keep things moving, plus strategic guidance to make sure you're moving in the right direction.
The right choice depends on your company's revenue stage, marketing maturity, budget constraints, and whether you need generalist executors or specialized strategic guidance.
Companies with less than £5 million ($6.25 million) in annual revenue typically see better ROI from fractional arrangements, while those above £20 million ($25 million) often benefit from transitioning to predominantly in-house structures with fractional specialists for niche capabilities.
Use this decision framework:
| Your Situation | Recommended Model |
|---|---|
| Startup (under £1M/$1.25M revenue) | Fractional team or individual |
| Growing (£1-5M/$1.25-6.25M revenue) | Fractional director + contractors |
| Scaling (£5-10M/$6.25-12.5M revenue) | Hybrid: 1-2 in-house + fractional leadership |
| Established (£10-20M/$12.5-25M revenue) | Small in-house team + fractional specialists |
| Enterprise (£20M+/$25M+ revenue) | Primarily in-house with fractional for gaps |
Start by asking yourself three questions:
If you answered "yes" to all three, in-house makes sense. If you said "no" to any of them, fractional or hybrid models likely deliver better ROI.
You've now seen how in-house and fractional models stack up, and what kind of marketing structure drives the best ROI at different stages.
If you're feeling stuck or unsure about your next hire, you're not alone. The businesses I work with are often in the same position when they reach out. Most growing companies face this exact challenge: needing marketing expertise without the overhead of full-time senior hires.
The smartest path forward? Start with fractional support to prove what works, then build your in-house team around those proven strategies. Companies under £5 million ($6.25 million) typically see significantly better ROI from this approach, while those over £20 million ($25 million) often benefit from dedicated internal teams with fractional specialists filling specific gaps.
