About the Headcount & Hiring Plan
Hiring is one of the largest and least reversible costs a growing company takes on, and the timing of each hire matters as much as the salary. This planner lets you lay out every planned role with its department, start month, and annual salary, then shows both the full-year salary cost and the prorated cost for the current year based on when each person actually starts.
That distinction is the whole point. A role budgeted at $130,000 costs the full amount only if the person works all twelve months; a mid-year hire costs a fraction of that this year. Seeing both numbers side by side keeps your annual budget realistic while making clear what the run-rate cost will be once everyone is on board.
How the Headcount & Hiring Plan works
For each role you enter a start month from 1 to 12 and an annual salary. The prorated this-year cost is salary times (13 minus start month) divided by 12. A January start (month 1) gives (13 - 1) / 12 = 1, the full salary. A start month is clamped between 1 and 12 so the fraction stays valid.
The totals row sums two columns: the full-year cost, which simply adds every annual salary, and the prorated this-year cost, which adds each role's prorated amount. Full-year total shows your eventual run rate; the prorated total shows what actually hits this year's budget given the staggered start dates.
Worked example
The sample plan has five roles totaling $535,000 in full-year salary: a Software Engineer at $130,000 (start month 1), Product Manager at $140,000 (month 3), Sales Rep at $90,000 (month 4), Designer at $110,000 (month 6), and Support Specialist at $65,000 (month 9).
Prorated, the engineer counts fully at $130,000 (starts in January), the PM at 140,000 x 10/12 = $116,667, the sales rep at 90,000 x 9/12 = $67,500, the designer at 110,000 x 7/12 = $64,167, and support at 65,000 x 4/12 = $21,667. Those sum to roughly $400,000 for this year, $135,000 less than the full-year run rate of $535,000, thanks to staggered starts.
Tips & common mistakes
- Salaries are only part of the cost; add a loaded-cost multiplier of about 1.25 to 1.4 to cover payroll taxes, benefits, and equipment when you present the true budget impact.
- Stagger start months deliberately to smooth cash flow; the prorated total drops sharply when key hires start later in the year, which can bridge a tight quarter.
- Use realistic start months, not optimistic ones; roles often take one to three months to fill, so a role you open in month 3 may not have someone starting until month 5.
- Group by department mentally as you plan so you can spot whether growth is balanced or overloaded in one function like sales or engineering.
- Revisit the plan quarterly; a delayed hire frees prorated budget that can fund an earlier start elsewhere without changing the full-year run rate.
Headcount & Hiring Plan: frequently asked questions
How is the prorated this-year cost calculated?
It is annual salary times (13 minus start month) divided by 12. A month-1 start yields a factor of 12/12 = 1 (full salary), while a month-4 start yields 9/12 = 0.75. So a $90,000 role starting in month 4 costs $67,500 this year.
Why is the full-year total higher than the prorated total?
The full-year total assumes every role is filled for all twelve months, showing your eventual run rate. The prorated total reflects staggered start dates, so mid-year hires cost less this year. In the sample, that gap is $535,000 versus about $400,000.
Does the plan include benefits and payroll taxes?
No, it uses base annual salary only. Real fully loaded cost is typically 25-40% higher once you add employer taxes, benefits, and equipment. Multiply the totals by roughly 1.3 for a more complete budget figure.
What does a start month of 1 versus 12 mean?
Month 1 is January (or the first month of your fiscal year) and month 12 is the last. A month-1 hire is counted at full annual salary this year; a month-12 hire is counted at just 1/12 of it, since they only work one month in the period.
Can I model replacing a departing employee?
Yes. Add the replacement as a new role with the month they start, and if the departing person leaves partway through, their prorated cost captures the months they were paid. Together the two rows approximate the overlap or gap cost of the transition.
