How this adjustment works0.93x

This divides the open roles counted on the last business day of the month by average monthly hires, so it reads as roughly how many months of hiring it would take to clear the current stock of openings. A high figure means employers are posting faster than they can fill. It is an adjustment rather than a measured sourcing rate, which is why it is shown separately and can be switched off.

Without it, the same funnel gives 469 candidates per hire. With it, 469 x 0.93 = 438.

A deadline shorter than the benchmark does not make the funnel convert better, it just raises the weekly outreach you need. That is the number worth arguing over in a kick-off meeting.

Why follow-ups change the number so much8.8% to 16.3%

Gem measured a cumulative 8.8% reply rate after one email, 13.7% after two and 16.3% after three, on 6.2 million sequences sent in 2025. The second email is the single biggest gain. Ashby and Lever both found the same shape on earlier data, and all three agree a fourth email adds very little.

Sending three emails instead of one roughly halves the number of people you need to contact. No other input on this page moves the answer that far, and it costs nothing but follow-up.

168
Why most published funnels look easier168 vs 438

Ashby publishes interview passthrough rates blended across every source: 35% at the recruiter screen, 24% at the loop, 81% offer acceptance. Those are dominated by inbound applicants and lifted by referrals and internal moves. Chain them and you get 168 candidates per hire.

Gem measures the same stages on outbound candidates alone and finds them harder: they clear the first screen at 86% because a sourcer already vetted them, then convert at 18% to the loop, 22% to an offer and 73% to a hire. That is a 2.5% application-to-hire rate against 0.3% for inbound. Since this tool is about cold outbound, it uses the outbound numbers, which is why its answer is larger.

The chain reproduces Gem's own published checkpoints: 8.6% converted to process, against the 8% Gem states, and 2.5% application to hire, against the 2.5% Gem states.

Reply rates fell through 202515.2%-23%

Gem publishes both years and labels the change itself: 22.6% in 2024 against 16.9% in 2025. That is a documented decline, not a disagreement between sources. This tool uses the 2025 figure rather than the more flattering older one.

hireEZ's 15.2% is measured per message rather than per sequence, so it is not directly comparable with the others and is shown for context only.

23% — Gem, June 2024 to May 2025, outbound candidates

19.6% — Ashby, January 2022 to January 2024

16.9% — Gem, calendar 2025, the figure this tool uses

15.2% — hireEZ, January to June 2025

Reply rates differ by industry more than this tool assumes12% to 25%

Ashby reports little variation by industry, but its customer base is almost entirely venture-backed software. hireEZ measured a much broader base in the first half of 2025 and found a two-fold spread. If you recruit outside technology, expect the reply step to be worse than the default here.

Information technology: 25%

Communication services: 22%

Industrials: 22%

Health care: 12%

Professional and commercial services: 12%

The tool does not apply these automatically, because the market adjustment already carries an industry signal and applying both would count it twice. Use the override below instead.

Sequence: a typical sequence (blended average) (18.1% reply rate).
Pace: 146 candidates sourced per week over 63 days (29 per working day). Median time to first fill for mid level roles is 63 days.

Cross-check: Gem measures outbound candidates at 2.5% application-to-hire, which puts the same outreach at 371 candidates per hire. Published sequence reply rates span 15.2% to 23%, so treat this as a range.

The honest answer is a chain, not a rule of thumb

“How many candidates do we need?” usually gets answered with a number someone half remembers. The real answer is a chain of conversion rates, and each link has been measured on a large dataset. Source a hundred people and about twenty reply. Fewer than half of those replies are a yes. Of the people who start the process, roughly a third pass the recruiter screen, a quarter get through the interview loop, almost everyone clears final checks, and about four in five accept the offer.

Multiply the chain and you land near 200 sourced candidates per hire for a typical role. That number is not a guess, and it is not ours: it comes from Ashby’s analysis of more than 500,000 sourcing sequences and 54 million applications, cross-checked against Gem’s 1.2 million hires. The calculator shows every link, and you can open each one to see the metric, the dataset and the source.

Reply rate is where roles separate

The stage that varies most is the first one. Ashby measured a 42% reply rate for legal and recruiting candidates, 21% for engineers and 20% for finance, against a 19.6% average. Engineers receive the most sourcing outreach of any group and open the least of it, so an engineering search can need twice the volume of a legal one to produce the same hire. Those role figures are from 2022 to 2024, so the tool applies the ratio between them to today’s baseline rather than reusing the old absolute numbers.

Follow-ups are the lever that actually moves the number

Of everything on the page, the input that changes the answer most is not the role or the industry. It is how many emails are in your sequence. Gem measured a cumulative 8.8% reply rate after one email, 13.7% after two and 16.3% after three, across 6.2 million sequences sent in 2025. The second email is the single biggest gain. Sources differ on where the returns stop: Gem puts the optimum at four emails, while Lever measured gains continuing to six on 2018 data.

Sending three emails instead of one roughly halves the number of people you need to contact. A recruiter who sends one email and gives up is doing about twice the sourcing work for the same hire.

Industry decides how hard the market is pushing back

Conversion rates describe your process. They say nothing about whether every other employer is chasing the same people. For that the calculator uses the US Bureau of Labor Statistics JOLTS release, which reports actual hires and unfilled openings by industry every month. Dividing openings by hires gives a plain measure of how far demand runs ahead of what the industry can fill.

  • Government sits at about 2.37, the tightest supersector, though federal government alone is tighter still at 3.55.
  • Financial services at about 2.03 and healthcare at about 1.98, well above average.
  • All industries average 1.37.
  • Construction at about 0.77, where hiring is fastest and churn highest.

The tool applies that ratio as a clearly labelled multiplier, shows the raw hires and openings behind it, names the exact BLS series so you can pull the data yourself, and lets you switch it off. It is the one figure that is an adjustment rather than a measured sourcing rate, so it is never folded in silently.

Use it to set expectations before the search, not after

The most useful moment for this number is the kick-off meeting. A hiring manager who wants three engineers this quarter is asking for several hundred sourced candidates, a few hundred outreach replies and a dozen interview loops. Showing that chain, with citations, turns “why is this taking so long?” into a conversation about capacity. Copy the plan out of the tool and paste it into the intake doc.

When you have your own conversion rates, use them. Enter any stage as a percentage and the whole plan follows your data, with the drill-down marking which rates are yours. Then build the search itself with the Boolean Search String Builder, widen it with the Synonym Expander, and point it at public profiles with the X-ray Search Builder.

Frequently asked questions

Across all roles the current benchmarks multiply out to roughly 165 sourced candidates per hire. That starts from a 16.9% reply rate and a 9.4% interested rate, measured by Gem across 6.2 million sequences sent in 2025, then a 35% recruiter-screen passthrough, 24% interview-loop passthrough, 95% final-checks passthrough and 81% offer acceptance from Ashby's 54 million applications. Reply rates fell sharply during 2025, from 22.6% to 16.9%, so any calculator still quoting the low twenties will understate the work by a wide margin.

Four published datasets. The outreach steps come from Gem's 2026 email outreach report, covering 6.2 million sequences sent in 2025, which is the most recent large dataset available. The interview steps come from Ashby's Recruiting Operations Benchmarks, 54 million applications across 93,000 jobs. Gem's 2026 Recruiting Benchmarks Report, 165 million applications and 1.2 million hires, cross-checks offer acceptance and outbound conversion. Hiring conditions by industry come from the US Bureau of Labor Statistics JOLTS release. Every figure names its source, dataset and date, and links to it.

Because reply rates do. Ashby measured legal and recruiting candidates replying at about 42% against a 19.6% average, with engineers at 21% and finance at 20%. Those figures are from 2022 to 2024, and reply rates have fallen since, so the tool applies the ratio Ashby measured to the current 2025 baseline rather than reusing the old absolute numbers. The relative gap is the durable finding: a legal search and an engineering search are not the same amount of work.

It compares your industry's unfilled openings per hire against the US average of 1.37, using Bureau of Labor Statistics JOLTS data. Financial services runs at about 2.03 and healthcare at 1.98, so both are meaningfully harder than average, while construction runs at 0.77. This is the one number in the tool that is an adjustment rather than a measured sourcing rate, so it is shown separately, the raw hires and openings are displayed, and you can switch it off.

Yes, and you should when you have them. Open the override section and enter any stage as a percentage; the whole calculation and the copyable plan follow your numbers, and the drill-down marks which stages are yours rather than a benchmark.
