Your recruitment team isn't just there to fill vacancies. It should help reduce the cost of filling them.
Recruitment agencies have their place. But if your internal recruitment team is growing, your agency spend shouldn’t be growing alongside it.
So how do you know whether your recruitment function is actually delivering a return on investment?
This guide shows you how to measure recruitment ROI, understand your true cost of hiring and build a recruitment budget that reduces unnecessary agency spend.
What does recruitment ROI actually mean?
Recruitment ROI isn’t simply about how many people you hire.
A high-performing internal recruitment team should help your business:
- Reduce external agency spend
- Lower cost per hire
- Fill vacancies faster
- Improve candidate quality
- Reduce recruitment administration
- Make better use of existing recruitment resources
- Build a reusable talent pipeline
The question isn’t just:
“How much did we spend on recruitment?”
It’s:
“What did we get back from that investment — and how much external spend did we avoid?”
Your recruitment team should be reducing agency dependency
If you’re investing in internal recruitment, one of the clearest measures of ROI is whether that investment allows you to bring more hiring in-house.
Think about it this way:
Your recruitment investment
Recruiter salaries
- ATS & recruitment software
- Job advertising
- Sourcing tools
- Recruitment administration
Your recruitment output
More candidates sourced
- More vacancies filled internally
- Faster hiring
- Better candidate experience
- Less agency spend
That’s the return you’re looking for.
How to build a recruitment budget that delivers ROI
1. Start with your current agency spend
Look at the last 12 months.
Calculate:
Number of agency hires × average salary × average agency fee
This gives you a baseline for your external recruitment spend.
Don’t forget retained search, specialist recruiters and other external recruitment costs.
2. Calculate your internal recruitment cost
Add up:
- Recruiter salaries
- Recruitment software
- Job boards
- Advertising
- Sourcing tools
- Candidate checks
- Recruitment administration
- Other recruitment technology
This gives you the actual cost of running your internal recruitment function.
3. Calculate your cost per hire
Your cost per hire can be calculated as:
Total recruitment costs ÷ number of hires
But don’t stop there.
Look at the difference between:
Internal cost per hire
and
Agency cost per hire
This helps you identify where your recruitment team can have the biggest financial impact.
4. Track the change over time
Your recruitment ROI becomes much clearer when you compare your numbers year-on-year.
Your recruitment team should become more valuable over time
The goal isn’t simply to maintain the same level of agency spend while adding an internal recruitment team.
It’s to build an internal function that becomes more capable, more efficient and less dependent on external recruitment over time.
- More hires handled internally.
- Less agency spend.
- Less recruitment admin.
- Faster hiring.
- Better visibility.
That’s what a recruitment function with measurable ROI looks like.
