Measuring Recruiting Marketing: Cost per Hire, Funnel Drop-Off, and Time-to-Fill Honestly

The same SME that knows its machine utilization to the percent and its customer acquisition cost to the euro often cannot say what its last hire cost, how long the position stood open, or which channel produced its best people. Recruiting sits in an accountability gap: HR tracks administrative completion, leadership feels the pain of vacancies, and nobody owns the numbers in between. The result is that budget flows by habit, the same job board subscription renewed annually because it was renewed last year, while the channels that actually produce hires go unfunded because nobody proved they work.

The fix is not an analytics platform. It is a handful of numbers, honestly collected, reviewed at the same monthly rhythm as your marketing and sales metrics. A spreadsheet suffices at SME scale. What matters is that the numbers exist, that they are honest, and that someone with budget authority looks at them regularly. Measurement is what converts recruiting from a recurring emergency into a managed system, exactly as it once did for your demand generation.

Cost per hire is total recruiting spend over a period divided by hires made in it, and the temptation is to count only job board invoices. Count honestly: agency and headhunter fees, referral bonuses, career page and content work, fair appearances, and a reasonable estimate of the internal hours spent screening and interviewing. The honest number is usually a multiple of the flattering one, and that is the point: it makes visible what a failed process costs, and it justifies upstream investment that looked expensive against the flattering number.

Time-to-fill, the days from opening a position to accepted offer, is your speed metric, and it carries a shadow number that matters more: the cost of the vacancy itself, in overtime, declined orders, and overloaded colleagues, for every day the position stays open. You do not need that number to be precise; even a rough day-rate for an unfilled role changes decisions, because it reframes recruiting spend against the cost of not hiring. Track both per role type, since a metric averaged across machinists and office roles hides everything useful. And note the honest tension: pressure to shrink time-to-fill degrades hiring standards, which is why these two numbers must never be read without the quality number that follows.

Source of hire is the cheapest, highest-leverage measurement you are not doing: for every application, record where it came from, and for every hire, trace it back. Ask candidates directly how they first heard of you, because the click source and the true source differ, someone who saw your apprentice's videos for a year and then searched your name is not job board traffic no matter what the form says. After a year you will know your real channel mix, and it almost never matches the budget mix. That comparison, hires by source versus euros by source, is the single most useful chart in recruiting.

Funnel drop-off tells you where the system leaks. Count the stages: views of the ad, applications started, applications completed, first conversations, offers made, offers accepted, and still employed after a year. Each ratio names a different problem, weak ads, broken forms, slow process, uncompetitive offers, or misleading promises, and each problem has a different owner and fix. Without stage counts, every debate about recruiting is opinion; with them, the leak is usually obvious within one review. This is identical to funnel analysis in marketing, and whoever runs that analysis for your demand gen can run this one in an afternoon a month.

The metrics above measure efficiency; quality of hire measures whether the machine produces the right output. Keep it simple and honest: is the person still here after a year, would the hiring manager enthusiastically hire them again, and are they performing at or above what the role needs. Reviewed by source, this is what stops the race to the bottom, because it reveals when a cheap fast channel produces hires who leave, and when an expensive slow one produces people who carry the company. Retention of hires by source and by cohort is the long-term truth-teller about both your recruiting promises and your actual workplace.

Then give the numbers a rhythm, because unreviewed metrics decay into decoration. Monthly: open positions, pipeline by stage, time-to-fill on current searches, and drop-off anomalies. Yearly: cost per hire, source mix versus budget mix, one-year retention, and the budget shifts those numbers demand. Keep the honesty rules explicit: count full costs, trace true sources, and report the numbers that embarrass you, since those are the only ones that change anything. An SME that runs this modest system for two years stops arguing about recruiting from anecdotes, and starts compounding the same way its marketing did when it first got real measurement.
