Headcount Planning Template & Calculator

What is headcount planning and why does it matter?

Headcount planning is the strategic process of forecasting and managing the number of employees an organization needs to achieve its business objectives. It goes beyond simply counting open positions. Effective headcount planning aligns workforce capacity with revenue targets, accounts for expected attrition, allocates recruiting budgets efficiently, and ensures each department has the people resources needed to deliver on their goals. Without a structured headcount plan, companies often overhire in some areas while leaving critical gaps in others, leading to wasted budget and missed targets.

How do I determine the right attrition rate for my plan?

The most accurate attrition rate comes from your own historical data. Calculate your trailing 12-month voluntary turnover rate by dividing the number of voluntary departures by the average headcount over the same period. If you do not have historical data, industry benchmarks can serve as a starting point. Technology companies typically see 13-15% annual voluntary attrition, professional services 12-14%, healthcare 8-12%, retail and hospitality 30-60%, and financial services 10-13%. Keep in mind that attrition rates vary significantly by department, seniority level, and geographic location.

What costs should I include in "cost per hire"?

Cost per hire should encompass all expenses associated with filling a position. This includes:

• Job board postings and advertising (typically $300-$1,000 per role)
• Recruiter time and salaries (internal recruiting team costs)
• External agency fees if used (usually 15-25% of first-year salary)
• Interview costs (interviewer time, travel for candidates)
• Background checks and assessments ($50-$500 per candidate)
• Onboarding and training costs
• Technology and equipment setup for new hires

According to SHRM, the average cost per hire in the US is approximately $4,700, though this rises significantly for specialized and senior roles.

How should I distribute hires across quarters?

The optimal quarterly distribution depends on your business model and hiring capacity. Common approaches include front-loading hires in Q1-Q2 to maximize productivity for the full year, aligning with seasonal business patterns (such as retail hiring ahead of peak season), spreading hires evenly to avoid overwhelming your recruiting team, and back-loading when budget approval timelines require it. For most companies, a distribution of 30-30-25-15 works well, as it gets most hires in early while allowing buffer for adjustments later in the year.

What is the "ramp cost" and why does it matter?

Ramp cost represents the productivity gap between when a new hire starts and when they reach full effectiveness. During this period, you are paying full salary but receiving reduced output. For most professional roles, new employees operate at roughly 25% productivity in month one, 50% in month two, and 75% in month three. For complex technical roles or senior leadership positions, full ramp-up can take 6-12 months. This calculator estimates ramp cost as 30% of salary during the ramp period, reflecting the average productivity deficit. Understanding ramp cost helps you plan for the true investment in new hires beyond just their compensation.

Should I backfill every departing employee?

Not necessarily. Attrition can be an opportunity to reallocate resources or restructure teams. Before automatically backfilling a role, consider whether the position is still strategically important, whether the work could be distributed among remaining team members, whether automation or process improvements could absorb the workload, and whether the budget would be better allocated to a different role or department. This calculator provides three backfill strategy options: full backfill to maintain current headcount, critical-only backfill for essential roles, and no backfill to absorb attrition through natural efficiency gains.

How often should I update my headcount plan?

Best practice is to review and update your headcount plan quarterly at a minimum. Many high-growth companies review monthly. Key triggers for an off-cycle review include significant changes in revenue projections, unexpected attrition spikes, M&A activity, new product launches or market entries, and changes in business strategy. The plan should be treated as a living document that adapts to changing conditions, not a static annual exercise. Regular updates ensure your hiring targets remain aligned with business reality.

What is "fully loaded cost" per employee?

The fully loaded cost represents the total cost of employing someone beyond just their base salary. It includes health insurance and benefits (typically 15-25% of salary), employer payroll taxes like Social Security and Medicare (7.65% in the US), 401(k) or retirement matching (3-6%), workers' compensation insurance, paid time off costs, equipment and technology, office space or remote work stipend, training and development, and any other perks. For US-based employees, the fully loaded cost is typically 1.25x to 1.4x the base salary. This calculator uses the benefits multiplier you specify to approximate this total.
