Recruitment KPIs Every Employer Should Track: 5 Critical Metrics
A Nairobi technology company hired three engineers in six months. All three left before their first anniversary. The managing director blamed the market. The HR manager blamed the candidates. Nobody looked at the hiring data. The time-to-fill was three days. The offer acceptance rate was 100%. On paper, the recruitment process looked efficient. In reality, it was fast and wrong.
The company brought the problem to us. They wanted to know why the hires were not lasting. We looked at their hiring process.
We found three things. The process was too fast – three days to fill a role, which meant the assessment was rushed. The assessment was weak – candidates were hired on presentation, not capability. The onboarding was rushed -new hires arrived without a plan.
We fixed all three. We rebuilt the assessment. We changed the interview questions and added a structured scorecard. We built a first-90-days plan for every new hire. The next three hires stayed.
Here are the recruitment KPIs that made the pattern visible, and what each one tells you.
The Five Metrics That Actually Predict Hiring Success
1. Time-to-fill.
How long does it take to close a vacancy? A long hiring process leads to lost productivity and candidate drop-off. But a very short process can also be a warning sign. If you are filling senior roles in three days, you are probably not assessing properly. The recruitment KPI matters, but it must be read alongside quality.
2. Quality of hire.
How well does the new employee perform after joining? This is more valuable than counting hires. Quality of hire can be assessed through performance against role expectations, manager feedback, time to productivity, and early retention. A company that fills vacancies quickly but repeatedly hires people who struggle is not tracking the right recruitment KPIs.
3. Offer acceptance rate.
How many candidates accept your offers? A low acceptance rate points to salary, employer branding, or slow decision-making. If several suitable candidates turn down offers, finding more candidates will not solve the problem. You need to understand why they are saying no. Understanding the market rate before the offer is made is where the fix starts.
4. New-hire retention.
How many employees are still with you after six or twelve months? High early turnover often reveals issues beyond recruitment. The role may have been misdescribed. The expectations may have been unclear. The onboarding that follows the hire is where the retention problem starts.
5. Source of hire.
Which channels consistently produce your best employees? The goal is not to collect more data. It is to make better hiring decisions. If referrals produce employees who stay and job boards produce employees who leave, the recruitment budget should follow the evidence. The recruitment KPIs tell you which channel deserves the investment.
Why Most Employers Track the Wrong Things
Most employers track vacancy fills. The role is open, the role is closed, and the recruitment team has done its job. That is a completion metric, not a quality metric. It tells you nothing about whether the person will stay, perform, or become a problem the line manager has to manage out.
We see this pattern in Kenyan businesses that hire quickly and lose quickly. The recruitment process is measured on speed. The cost of the bad hire is measured in resignations, re-recruitment, and the productivity lost while the role sits open again. When the role itself was wrongly defined, redefining the mandate before the next hire is where the fix begins.
Questions Employers Ask About Recruitment KPIs
“We do not have an HR system. Can we still track these recruitment KPIs?”
Yes. A simple spreadsheet works. We set this up for the Nairobi tech company in a week. Time-to-fill is tracked from the date the vacancy opens to the date the offer is accepted. The offer acceptance rate is a count of offers made against offers accepted. New-hire retention is a count of hires still employed at six months. None of it requires software.
“Which recruitment KPI should we start with?”
We tell employers to start with quality of hire and new-hire retention. Those two tell you whether the process is producing people who stay and perform. Time-to-fill and offer acceptance rate are secondary until the quality is consistent.
“Our recruitment team says the metrics are fine. Why are we still losing people?”
Because the metrics your recruitment team tracks may be completion metrics, not quality metrics. Filling a vacancy on time is not the same as filling it with the right person. Ask what the quality-of-hire score is. Ask what the six-month retention rate is. If those are not being tracked, the picture is incomplete. We review the recruitment KPIs for employers who suspect the picture is incomplete, and we tell them what the data actually shows.
“We use a recruitment agency. Should we still track these recruitment KPIs?”
Yes. The agency tracks its own performance, but you need to track the outcome. Time-to-fill measures the agency’s speed. Quality of hire and retention measures, whether the agency’s assessment was accurate.
“How long before we see a difference?”
Two hiring cycles. The first cycle sets the baseline. The second cycle shows whether the changes are working. If the quality-of-hire score is rising and the six-month retention rate is improving, the recruitment KPIs are working. If not, the assessment criteria need revisiting. We work with employers through both cycles.
What the Data Actually Tells You
The data does not tell you who to hire. It tells you where the process is breaking. A low quality-of-hire score does not mean the candidates were bad. It means the assessment was not testing the right things.
A low retention rate does not mean the employees were disloyal. It means the role or the onboarding was not what they expected.
Because recruitment KPIs are not about proving the hiring team is busy. They are about proving the hire will last.
