Time to fill is a metric that measures the average number of days it takes to fill an open position from the date a new role is posted to the date a candidate accepts an offer.
Time to fill is different from time to hire, with the former measuring the entire hiring period and the latter focusing on the candidate's journey through the hiring pipeline.
For internal searches, time to fill can be a useful KPI, but for external searches, it may not fully capture the value of a search firm.
To calculate time to fill, organizations can track the total number of days from the job posting date to when a new hire accepts an offer, and consider variations based on role, industry, and seniority.
