A headcount plan says how many people you want on staff by year-end. A hiring capacity plan says what it will take to get them: how many applicants, how many hours of your managers' time, and how many weeks. Most companies skip the second step, then discover in March that every manager is interviewing at once and nobody is doing their actual job. This guide walks through the method with worked numbers you can replace with your own.
Step 1: count the hires, not the headcount
Net growth understates the real number. If you have 60 employees and plan to grow to 72, you aren't making 12 hires. You're making 12 plus however many people leave.
Pull last year's departures from payroll or your HR file. Suppose 9 people left out of an average of 58 staff: that's roughly 15% turnover. Applied to an average of 66 staff next year (halfway between 60 and 72), expect about 10 departures. Your hiring target is therefore:
- growth hires: 12
- replacement hires: about 10
- total: about 22 hires
That's nearly double the number most owners would say if asked. Replacement hires also arrive unannounced, so they're the ones that create panic.
Step 2: group roles into families
Different roles behave differently. Group your 22 hires into two to four families that share a pipeline. A typical split:
| Role family | Planned hires | Notes |
|---|---|---|
| Customer-facing staff | 12 | Higher volume, faster process |
| Specialists | 6 | Smaller pool, longer search |
| Supervisors and managers | 4 | Mix of internal and external |
Each family gets its own conversion rates in the next step. Treating them as one average hides the specialist roles that will take three times as long.
Step 3: work out your stage conversion rates
For each family, reconstruct the last three to five hires. For each, count how many people reached each stage. Here's an illustrative set for the customer-facing family:
| Stage | Candidates per hire | Pass-through |
|---|---|---|
| Applied | 80 | |
| Passed screening | 16 | 20% |
| Phone screen completed | 10 | 63% |
| Interviewed | 5 | 50% |
| Offered | 1.3 | 26% |
| Accepted | 1 | 77% |
And for specialists, where the pool is thinner but the screen pass rate is higher:
| Stage | Candidates per hire |
|---|---|
| Applied | 30 |
| Passed screening | 9 |
| Phone screen completed | 6 |
| Interviewed | 3.5 |
| Offered | 1.4 |
| Accepted | 1 |
If you've never tracked this, your first set of numbers will be rough. That's fine; the plan is mostly sensitive to the big stages, and you'll improve the numbers as you go. Our recruiting metrics service sets up the tracking so next year's plan starts from real data.
Step 4: multiply out the volume
Now multiply hires by candidates per hire.
Customer-facing (12 hires): 960 applicants, 192 screened in, 120 phone screens, 60 interviews, 16 offers.
Specialists (6 hires): 180 applicants, 54 screened in, 36 phone screens, 21 interviews, about 8 offers.
Supervisors (4 hires): suppose 25 applicants per hire, 3 interviews per hire and about 5 offers in total: 100 applicants, 12 interviews.
Across the year that's roughly 1,240 applications, 156 phone screens and 93 interviews. Laid out like that, the question is no longer "can we hire 22 people?" but "who is going to read 1,240 applications and run 93 interviews?"
Step 5: convert volume into hours
Assign a realistic time to each activity, including note-taking and scheduling:
| Activity | Minutes each | Count | Hours |
|---|---|---|---|
| Screening an application | 3 | 1,240 | 62 |
| Phone screen (incl. notes) | 30 | 156 | 78 |
| Interview, per interviewer | 75 | 93 × 2 interviewers | 233 |
| Debrief and decision | 20 | 93 | 31 |
| Offers and reference checks | 90 | 29 | 44 |
That's about 450 hours of recruiting work in the year, or roughly 11 full working weeks, before anyone writes a job ad or answers a candidate's question. Spread across managers, it's manageable. Landed on one office manager in a busy quarter, it isn't.
This is the number that justifies process changes. If a structured hiring process cuts interviews per hire from 5 to 4 by screening better, it removes 12 interviews a year in the customer-facing family alone: about 30 interviewer-hours, plus the debriefs.
Step 6: put it on a calendar
Hires don't arrive evenly. Map them by month using the business plan (when new locations open, when contracts start) and spread replacement hires evenly unless you know your turnover is seasonal.
Then add lead time. If a customer-facing hire typically takes 5 weeks from posting to acceptance, plus 2 weeks' notice for the new person, the role must open 7 weeks before the start date. For specialists, it might be 10 weeks plus notice.
Plot the result and look for collisions: months where several families are recruiting at once and the same managers are interviewing for all of them. Those are the months to plan around, by opening some roles early, or by running a focused candidate attraction campaign before the crunch.
Canadian seasonality matters here. Employers with outdoor or seasonal work often hire in late winter for spring starts, while many office employers see a slow August and a busy September. The region pages describe how climate and local labour pools shape timing in each province and territory.
Step 7: test the plan against reality
A capacity plan is only useful if you check it. Each month, compare:
- hires made versus planned
- applications received versus needed
- actual conversion rates versus assumed
- recruiting hours spent versus planned
If applications fall short, the fix is at the front: your job ads and careers pages. If applications are fine but hires lag, the fix is in the middle: speed and process.
Common mistakes in hiring plans
Ignoring turnover. As Step 1 shows, it can nearly double the hiring load.
Using one conversion rate for every role. Specialist and volume roles behave completely differently.
Forgetting interviewer time. Two interviewers per interview doubles the hours, and managers' time is the scarcest resource.
Assuming every offer is accepted. Build in declines, and track the reasons.
Planning once a year. Business plans change; the hiring plan has to move with them.
Making it routine
Build this as a single spreadsheet with one tab per role family and a summary tab that adds up hours and months. Refresh conversion rates each quarter from your applicant tracking system, and review the summary at the same meeting where you review sales or operations. Hiring capacity is an operating constraint like any other.

Frequently asked questions
What is hiring capacity planning?
It's working backwards from the number of people you need to hire to the volume of candidates, hours of screening and interviewing, and weeks of lead time that the hiring will take. It shows whether your team can actually deliver the plan.
Where do I get conversion rates if I've never tracked them?
Reconstruct them from the last few hires using your inbox, job board accounts and calendar. Rough numbers from five real searches beat industry averages from somewhere else.
How often should the plan be updated?
Review it monthly against actual hiring, and rebuild it when the business plan changes. The conversion rates themselves should be refreshed every quarter.
Does this include replacing people who leave?
It should. Expected turnover is usually the largest hidden part of a hiring plan, and the method below adds it explicitly.
