Time to Hire vs. Time to Fill: What's the Difference?
These two metrics measure different things — and confusing them means you'll diagnose the wrong bottleneck.
Time to Hire
Days from when a candidate enters your pipeline (applies or is sourced) to when they accept the offer. Measures candidate experience and pipeline efficiency.
Time to Fill
Days from when a role is officially opened (approved headcount) to when it is filled (offer accepted). Measures total recruiting capacity and planning efficiency.
Example: A role opens on January 1. Your recruiter takes 2 weeks to post the job and start sourcing. The eventual hire applies on January 15 and accepts on February 14. Time to hire = 30 days (Jan 15 → Feb 14). Time to fill = 44 days (Jan 1 → Feb 14).
The 14-day gap between TTH and TTF represents recruiting setup time — a metric that only appears in time to fill. If you only track time to hire, you're missing the overhead cost of opening a role.

How to Calculate Average Time to Hire
To calculate your team's average across multiple hires in a period: sum all individual time-to-hire values and divide by the number of hires. Most ATS platforms calculate this automatically — but they often use inconsistent start-date definitions, so verify what date field your system uses as the start point.
