Headcount Planning: What Each Hire Really Costs, and When to Make It

Headcount planning is the process of deciding who a company will hire, in which team and in which month, and what each of those hires will cost. A headcount plan lists every current employee and planned role with a start date and a fully loaded cost, then rolls them up into monthly payroll, burn and runway. For most startups, people are the largest single cost, so the headcount plan is where most of the operating budget is decided.

Two numbers usually surprise founders. The first is that an employee costs well over their salary. The second is that when you hire can matter as much as who. In the worked example below, hiring the same eight people at the start of the year instead of spreading them out costs an extra $480,000 and five months of runway.

What is headcount planning?

Headcount planning connects three things that are often managed separately: the hiring plan (who and when), the budget (what it costs) and the cash forecast (how long the money lasts).

A good headcount plan answers:

• Who are we hiring, and why? Each role is tied to a goal, such as more pipeline, faster product delivery or lower churn.
• When do they start? The start month often moves cost more than the salary decision does.
• What will each person cost, fully loaded? That means salary plus employer taxes, benefits, tools, recruiting and equipment.
• What does the plan do to burn and runway? Month by month, not just at year end.
• When does each hire become productive? This matters most for sales roles, which take months to ramp.

Headcount planning is usually done once a year as part of the annual operating plan, then updated every month as hires slip, roles change and revenue comes in above or below plan.

This free Excel headcount planning template does the math in this article. List your current team and planned hires, and it calculates fully loaded cost, monthly payroll by team, burn, ending cash and runway. It flags any month where runway falls below your target, and any roster row with missing inputs.

What's inside:

• Assumptions: employer taxes and benefits, per-head tools, recruiting and equipment costs, sales ramp time, starting cash, revenue and other operating costs. Each default either shows its source or is marked illustrative.
• Roster: up to 40 people and planned roles, with team, status, start month, base salary, variable pay and whether the role carries a quota.
• Monthly Cost: each person's cost by month, one-off recruiting and equipment costs in the hire month, and ramped capacity for quota-carrying reps.
• Summary: headcount and cost by team, revenue, burn, ending cash, runway on recurring burn and a runway-target check.

The example inside is an illustrative 12-person software company planning eight hires, the same company used in the worked example below. Move a hire two months later and watch runway change on the Summary sheet.

What a hire really costs

An employee's salary is only part of what they cost. The rest comes from employer payroll taxes, health insurance, retirement contributions, software, equipment and the cost of hiring them in the first place.

The U.S. Bureau of Labor Statistics measures this every quarter. In June 2026, private-industry employers paid $32.82 an hour in wages and salaries and $14.07 an hour in benefits. Insurance, retirement and legally required benefits such as payroll taxes came to $8.66 an hour. Measured against wages plus paid leave, which is how an annual salary works, that is about 24% on top of salary, which the template rounds to 25%. Bonuses and commissions add to it.

Hiring has its own cost. SHRM's 2025 benchmarking puts the average cost per hire at $5,475 for non-executive roles and $35,879 for executives. That figure covers external and internal recruiting spend, but not interviewers' time or the cost of the empty seat. A single agency placement can cost far more than the average.

One senior engineer, $160,000 base salary:

So a useful rule of thumb is that a salaried hire costs about 1.25–1.35x their base salary in the first year. A plan that budgets salary alone understates payroll by roughly a quarter.

Sales hires: plan for the ramp

Sales hires add a second gap: time. A new account executive is paid from day one but doesn't reach full productivity for months. In the Bridge Group's 2024 SaaS AE Report, covering 172 B2B software companies, the average account executive ramp time was 5.7 months, up from 4.3 months in 2020. The same report found only 51% of account executives hit quota, down from 66% in 2022.

Take an account executive with a $100,000 base and $50,000 of variable pay at target. At 25% taxes and benefits plus tools, their fully loaded cost is $191,100 a year, assuming variable pay at target is paid (or drawn) during the ramp. With a six-month linear ramp, they deliver about one-sixth of a fully ramped rep's output in month one, two-sixths in month two, and so on, reaching full productivity in month six.

Over their first twelve months, that adds up to 9.5 productive months, not 12. Per productive month, the first year costs about a quarter more than a fully ramped rep's.

The planning consequence is simple. A sales hire made in October contributes almost nothing to this year's revenue. If the plan needs more bookings in the second half, the hires have to land in the first. And if barely half of reps hit quota, revenue capacity should be planned below 100% of quota per rep.

Worked example: the same eight hires, two timelines

A software company has 12 employees and $3.0 million of cash. It brings in $150,000 of revenue a month, growing 4% a month, and spends $60,000 a month on everything other than people. It plans eight hires: two engineers and a senior engineer, two account executives, a sales development rep, a customer success specialist and a growth marketer. Both plans use the same people, salaries and assumptions as the template. Only the timing differs.

• Staggered: hires start between month 2 and month 10, as each role becomes necessary
• Front-loaded: all eight start in month 1

Illustrative. Revenue is identical in both plans. Runway is ending cash divided by that month's recurring burn, excluding one-off hiring costs. Ending cash and net burn mirror each other because both plans start from $3.0 million.

The team is identical by month 12, and so is the monthly burn from then on. But front-loading costs an extra $480,000 in payroll and per-head costs for people who are on payroll before they are needed. That leaves the company with five fewer months of runway going into its next raise.

Front-loading pays off only if the early hires bring revenue forward by more than they cost. Sometimes that's true, for example sales reps who need their ramp time before a busy season. Often it isn't. The plan should make the case for each early start explicitly.

How to build a headcount plan

1. Start with today's roster. List everyone on payroll with their team, salary and variable pay. This is the baseline, and it's often less accurate than founders expect.
2. Tie every new role to a goal. "Second account executive, to reach $X of new bookings by Q3" is a plan. "Grow the sales team" isn't.
3. Set the start month, then test it. Ask what breaks if the role starts two months later. If nothing does, move it.
4. Use fully loaded costs. Salary × (1 + variable pay) × (1 + taxes and benefits), plus tools, with recruiting and equipment as one-offs in the hire month.
5. Model ramp for revenue roles. Sales capacity should come from ramped quota-carrying reps, not from headcount.
6. Roll it into the cash forecast. Feed headcount cost into your 3-statement model or financial model, and check runway every month of the plan, not just at year end.
7. Set a runway floor and a trigger. For example, if runway falls below 12 months, unstarted hires pause until it recovers. The template flags any month below your target.
8. Update it monthly. Compare actual hires and start dates with the plan, and reforecast. Hiring rarely happens on schedule, and a late hire is cash saved that the forecast should show.

For week-by-week cash, a rolling 13-week cash flow forecast sits underneath the headcount plan and catches payroll timing issues early.

Common mistakes

1. Budgeting salary, not fully loaded cost. It understates payroll by about a quarter.
2. Counting heads instead of capacity. Five sales reps in their first months aren't five reps of quota.
3. Hiring to a year-end headcount number. Who you'll have in December matters less than when each person starts.
4. Forgetting one-off costs. Recruiting, agency fees and equipment land in the hire month and can make that month's burn spike.
5. A plan that never changes. If hires slip, the cash forecast should show the saving. If revenue lags, the plan needs a trigger to slow hiring.
6. No owner. Finance builds the model, but each department head should own their roles, start dates and the goal each hire serves.
