Which recruiting metrics should you track first?

Start with one speed metric, one funnel metric and one outcome metric. Time to fill tells you how long seats stay empty, offer acceptance rate tells you whether your offers land, and new hire turnover tells you whether the people you hire stay. Agencies add fill rate and spread, because those two decide revenue.

Track each one the same way every month. A metric only becomes useful when you can compare it with last quarter and see which change moved it.

Frequently asked questions

What is the most important recruiting metric?

There is no single one. Most teams get the most value from time to fill, offer acceptance rate and new hire turnover together, because they cover speed, how well offers land and whether hires stay. Agencies should add fill rate and spread, since those drive revenue directly.

How often should recruiting metrics be reported?

Monthly works for most teams, with a quarterly review to spot trends. Weekly numbers swing too much on small volumes, so use them for pipeline management rather than for judging performance.

Are these calculators free to use at work?

Yes. They are free, need no account and run in your browser, so you can use them with real numbers without sharing anything.
