About the Hiring Funnel Calculator
This hiring funnel calculator works backward from the number of people you need to hire. Enter your offer acceptance rate and the pass-through rate at each earlier stage — application review, phone screen and interview — and it tells you how many offers, interviews, screens and applicants your pipeline needs, plus the overall applicant-to-hire yield.
Recruiters and hiring managers use it to set sourcing targets at the start of a search, to explain to stakeholders why a role needs hundreds of applicants, and to see which stage is the bottleneck. Improving a weak stage (for example, a low offer acceptance rate) can shrink the top of the funnel far more than spending more on job ads.
By default each stage is rounded up to whole people, because you cannot interview 27.5 candidates — this is the safe planning number. Turn rounding off to see the pure ratio. Pass-through rates vary widely by role, seniority and sourcing channel, so use your own applicant tracking system history where you can; the defaults are only a plausible example for a professional role.
With the default inputs, the applicants needed is 467. Change any value above to recalculate instantly.
How to use the hiring funnel calculator
- 1Enter the number of hires you need for the role or hiring plan.
- 2Enter pass-through rates for each stage, ideally from your applicant tracking system.
- 3Choose whether to round up to whole candidates at each stage.
- 4Add sourcing cost per applicant and interviewer hours to size the effort.
- 5Use the applicant target to plan sourcing, and the tightest stage to decide where to improve.
Formula and method
A hiring funnel is a chain of conversion rates. Starting from the hires you need, each step backward divides by the share of candidates who make it through the next stage: hires ÷ offer acceptance gives the offers to make, offers ÷ the interview-to-offer rate gives interviews, and so on up to applicants. With rounding on, each stage is rounded up to a whole person before moving to the previous stage, which gives a slightly larger, safer target.
The overall applicant-to-hire yield is the product of all four rates, and its reciprocal is the number of applicants per hire. Sourcing cost is applicants × cost per applicant, and interviewer hours are interviews × hours each. The model assumes rates are stable across the search and does not include candidates withdrawing between stages unless that is built into your rates.
- Screen rate
- Share of applicants invited to a phone screen
- Interview rate
- Share of phone screens advanced to interview
- Offer rate
- Share of interviewed candidates who receive an offer
- Acceptance
- Share of offers accepted
Worked examples
5 hires for a professional role
With 80% acceptance, 5 hires need 7 offers (6.25 rounded up). At a 25% offer rate that is 28 interviews, which needs 70 phone screens at 40%, which needs 467 applicants at a 15% screen rate. The pure yield is 1.2%, about 83 applicants per hire, and sourcing costs 467 × $20 = $9,340.
Same funnel without rounding
Without rounding, 5 ÷ 0.8 ÷ 0.25 ÷ 0.4 ÷ 0.15 = 416.7 applicants. Rounding at every stage adds a buffer of about 50 applicants because each partial person is rounded up before multiplying back.
High-volume hourly hiring
20 hires ÷ 90% acceptance = 22.2, so 23 offers. 23 ÷ 70% = 32.9, so 33 interviews; 33 ÷ 60% = 55 screens; 55 ÷ 50% = 110 applicants. The yield is 0.5 × 0.6 × 0.7 × 0.9 = 18.9%, and sourcing costs 110 × $8 = $880.
Frequently asked questions
How many applicants does it take to make one hire?+
It varies enormously by role. High-volume hourly roles may need only a handful of applicants per hire, while competitive professional or technical roles with open job postings can need 50 to 200 or more. Your own funnel data is the best guide — divide applicants by hires over the last few searches.
What is a recruiting yield ratio?+
A yield ratio is the share of candidates who move from one stage to the next, such as screens to interviews. Multiplying the stage yields gives the overall applicant-to-hire yield, and its reciprocal is the number of applicants needed per hire.
What is a good offer acceptance rate?+
Many organisations aim for 80–90% or higher. A lower rate usually signals pay below market, a slow process, weak candidate experience or a mismatch in expectations discovered late. Because every offer represents several interviews, small gains here shrink the whole funnel.
Why round up at each stage?+
You cannot screen or interview part of a person, and falling one candidate short at a late stage can mean missing a hire. Rounding up at every stage gives a conservative target. Turning rounding off shows the pure mathematical ratio, which is useful for comparing funnels.
Which funnel stage should I improve first?+
Start with the stage that has the lowest pass-through rate, because the funnel multiplies: lifting a 15% screen rate to 20% cuts applicants needed by a quarter. Often the cheapest fix is better job descriptions and targeting, which raises the quality of applicants entering the funnel.
