Recruitment marketing agency or in-house: costs and break-even compared

The real question behind choosing a recruitment marketing agency

At its core, the choice around recruitment marketing is simple: do you buy in expertise, or build it internally? This decision affects your budget, your speed, and the knowledge you build up within the company. That's why it's worth looking beyond cost alone. The number of hires per year is often decisive; the maths looks very different at five hires than at fifteen. Scarcity in the labour market matters too. Hard-to-fill profiles often call for a specialist approach, which directly influences the choice between a recruitment marketing agency and in-house recruitment marketing.

When a recruitment marketing agency makes sense for your organisation

A recruitment marketing agency fits perfectly with a low or unpredictable hiring volume. You pay per campaign or per hire, so you're not tied to ongoing salary costs. That makes scaling up straightforward. On top of that, you bring in experience immediately. A specialist recruitment marketing agency knows exactly which channels work and actively steers on data, so you avoid a long learning curve and see results much faster.

There are different types of agencies out there. Some focus heavily on advertising and data, while others excel at employer branding or search. Want to see what this looks like in practice? Take a look at how agencies approach outreach at scale to work out which approach fits your situation best.

The downsides of a recruitment marketing agency in practice

The cost per hire through a recruitment agency is often considerably higher. Many agencies charge a percentage of the annual salary or a hefty fixed fee. As a result, the cost per hire through an agency rises sharply once you're hiring more people. That makes outsourcing your recruitment marketing far less attractive when the organisation is growing fast.

You also have less direct control over your employer brand. External partners simply know your company culture slightly less well, and that often shows in external communication and the candidate experience. Also pay close attention to who owns your employer brand data. Without clear agreements, candidate and campaign data can end up belonging to the agency. Always set out in advance who is the rightful owner of accounts, tracking pixels, and the talent pools you build.

When a recruitment marketing agency becomes less suitable and in-house gets stronger

Once you're dealing with a stable hiring volume, in-house recruitment marketing quickly becomes the cheaper option. The cost of an in-house recruiter stays largely fixed, while the number of hires rises. The logical result is that the average cost per hire drops. Internal teams also coordinate much faster with hiring managers and can adjust running campaigns immediately. When comparing a recruitment agency with an in-house team, it becomes clear that internal recruiters work far more efficiently once the processes are properly in place.

Recruitment marketing agency versus in-house recruitment marketing explained

Working in-house gives you full control over all your data and processes. You build valuable knowledge internally and continuously strengthen your employer brand. That comes with fixed costs, though, such as salaries, tooling and advertising budget. There's also a certain risk when critical knowledge sits with just one person.

An agency, on the other hand, offers plenty of flexibility and speed. You buy in targeted expertise without taking on direct employer risk for it. Of course, that comes with a certain dependency, plus less direct control over the work. Long-term contracts and minimum fees also have a significant impact on your budget. This choice therefore always comes down to a careful trade-off between flexibility and control.

Recruitment marketing agency or in-house: how to calculate the break-even point

Your recruitment marketing break-even point shows exactly when an in-house approach becomes cheaper. You calculate this using a few key variables: the expected number of hires per year, the average agency fee, a recruiter's salary, tooling costs and your advertising budget. Start by adding up all the agency costs and dividing that figure by the number of hires. Then do exactly the same for your expected internal costs. The option with the lowest outcome is, financially speaking, the logical choice.

An example at five hires a year: an agency charges £8,000 per hire, which comes to £40,000 in total. An in-house recruiter, by contrast, costs around £55,000. In this particular case, outsourcing is clearly the cheapest option.

An example at twelve hires a year: agency costs now come to £96,000. In-house costs sit at around £68,000, tooling included. At this volume, working in-house becomes considerably cheaper.

An example of the hybrid model: you handle most of the recruiting yourself and only bring in external capacity for the genuinely scarce roles. In various real-world examples from recruitment teams, you can clearly see that this approach often results in the perfect balance.

Making in-house scalable alongside a recruitment marketing agency

Your team's productivity ultimately determines how quickly you reach this financial tipping point. With the right tooling, you can reach far more candidates without having to hire extra people straight away. Think, for example, of making your personal LinkedIn outreach more efficient, so recruiters can start more quality conversations in less time. This shifts the break-even point firmly in your favour.

If you want a clear picture of how this works, take a look at the differences between working manually and using tooling. That makes it easy to work out what fits your team and your ambitious growth plans best.

Key things to watch when choosing a recruitment marketing agency

Always pay close attention to data protection rules and data ownership. Make sure you retain access to both the candidates and the campaign data collected at all times. Also ask the agency for full transparency on reporting and the KPIs achieved. Finally, look closely at the agreed contract length and the flexibility on offer. All of these factors determine how agile your organisation remains once hiring needs change suddenly.

Four questions to help you choose: recruitment marketing agency or in-house

• How many hires do we expect this year, and how stable is that volume?
• How scarce are the roles we want to fill in the short term?
• How important is control over data and processes to our own team?
• Do we prefer variable costs, or would we rather invest in fixed in-house capacity?

Frequently asked questions about a recruitment marketing agency and in-house

What's cheaper: a recruitment marketing agency or in-house?
With a consistently low number of hires, an agency is often cheaper. Once volume is higher and more stable, however, an in-house approach usually becomes more cost-effective because the cost per hire drops sharply.

When should you outsource recruitment marketing?
This is a highly logical step during unexpectedly fast growth, a lack of in-house knowledge, or when hiring for hard-to-fill roles. In these cases, you're essentially buying in the expertise and hiring speed you need straight away.

What are the main costs of an in-house recruiter?
The main cost items are base salary, employer costs, the required tooling and advertising budget. These costs also stay relatively stable, even as your recruitment output keeps growing.

Why does data ownership matter so much?
Because you want to retain control over your candidates, talent pools and the campaign data collected at all times. This ownership largely determines how independent you remain from external partners.
