The True Hidden Cost of an Open Role

Every position in your company exists for a reason: to produce measurable, tangible results.
When that seat is empty, your business is losing value by the hour. Let me explain how.
Let’s say:
- The role has a salary of $150K/year (in tech/engineering, this is the median)
- It’s been open for 90 days (which is common in today’s market)
Estimated cost of vacancy after 90 days? ➡️ $103,846
Here’s why:
On average, a fully-functioning employee produces 2x to 3x their salary in annual ROI.
So, every day the position goes unfilled, your business misses out on that potential return.
Simple formula:
(Annual Value of Role) ÷ (Work Days per Year) × (Days Open) = Cost of Vacancy e.g. ($300K ROI ÷ 260 days) × 90 days = $103,846 in lost value
And that’s not including:
- The added workload on current staff, pulling them away from their core responsibilities (fast track to burnout)
- The ramp-up period needed to get new hires to full productivity
- Training, onboarding, and internal resource costs
Why Agency Recruiters Make Sense:
Hiring speed matters!
An experienced recruiter can help you reduce time-to-fill, improve hire quality, and minimize lost ROI.
Typical timelines:
- Agency recruiter: 6–8 weeks time to fill (early as 4 weeks depending on the difficulty of the role)
- Internal team: 11–13 weeks (while juggling other responsibilities)
If your role has been open for more than 4 weeks, it’s time to bring in reinforcements. Yes, agency fees are higher upfront, but they save you far more over time.
Here’s how:
Example ROI (Based on $150K Salary)
- 30-day ramp-up to full productivity (some cases longer)
- The break-even point is around month 7
- Total value of role over 12 months:
a) At 2.7x ROI → $405,000
b) At 8.3x ROI → $1,245,000
(Recruiter fee (25–30% of $150K salary): → $37,500–$45,000 upfront)
Net Gain After Recruiter Fee
At 2.7x ROI:
- Total value: $405,000
- Minus fee: $45,000
- Net gain: $360,000
At 8.3x ROI
- Total value: $1,245,000
- Minus fee: $45,000
- Net gain: $1.2 million
Speed matters. Even with a higher upfront cost, working with the right recruiter protects profit, restores team bandwidth, and drives massive long-term value.
Even at the low end of the ROI scale, you’re seeing a net gain of $360K by year-end, not including avoided burnout, team retention, and the operational momentum regained by filling the role faster.
Hiring speed isn’t a luxury; it’s a measurable business advantage.
