What a hire really costs and how to budget for it
The salary on the offer letter is the part everyone sees. The employer pays a good deal more, and the business only benefits from the hours that are actually productive. This guide builds the full picture in the order a budget needs it: the yearly cost, the cost per useful hour, what raises and leave do to it, what losing the person would cost, and what each person has to bring in.
1. Salary plus everything on top
On top of gross salary the employer pays statutory contributions, which vary by country and are usually a percentage of pay, then benefits such as health cover, pension matching or allowances, then the overheads that exist because the person exists: a laptop, software seats, a desk, training. Together these commonly add a quarter to a half again to salary. The employee cost calculator adds them up and gives the yearly and monthly cost and the multiplier on salary, which is the quickest rule for future hires: a multiplier of 1.3 means a 50,000 salary costs 65,000.
2. The cost per productive hour
Dividing the yearly cost by contracted hours understates the real figure, because nobody is productive for every hour. Holidays, public holidays and sick leave reduce the weeks worked; meetings, admin and breaks reduce the productive share of each week. Forty-six working weeks at eighty percent productive time is a reasonable starting point for office roles. The same calculator gives the cost per productive hour, which is the number to compare with a contractor's rate, to use when pricing work by the hour, and to beat with the bill rate if the person's time is sold to clients. The day rate to salary calculator runs the comparison with a contractor the other way round.
3. Converting pay the way people talk about it
Candidates think in annual salary, hourly workers think in rates, and managers think in monthly budget. The salary to hourly calculator converts between annual, monthly, weekly, daily and hourly pay using the real hours and weeks rather than the 2,080-hour shortcut. The hourly figure is gross pay to the employee; the cost per productive hour from step two is what it costs the business, and the gap between them is the point of this guide.
4. Raises cost more than the raise
A five percent raise on salary raises the employer's contributions and often the benefits that scale with pay, so the cost to the business rises by more than five percent of salary. The pay raise calculator converts a raise between percentage and amount and shows the monthly and hourly difference for the employee; put the new salary back into the employee cost calculator to see the effect on the yearly cost. Budget raises across a team by the cost increase, not by the headline percentage.
5. Paid time off is a liability on the books
Leave accrues each pay period and is owed whether or not it is taken. For budgeting, it reduces the weeks worked in step two; for cash, unused leave may have to be paid out when someone leaves. The PTO accrual calculator works out accrual per pay period, the balance to date and the days still to be earned this year, which is also what an employee needs to plan a holiday without borrowing against future accrual.
6. What losing the person would cost
Turnover is the cost nobody budgets because it never arrives as one invoice. Recruiting, the weeks the seat is empty, onboarding, and the months during which a new hire is paid in full but produces a fraction of the output add up to a large share of the role's annual cost. The employee turnover cost calculator values each part from the role's daily cost and gives a cost per leaver and per year at your turnover rate. Set against that, a retention raise or better onboarding usually looks cheap.
7. What each person has to bring in
The hire pays for itself only if the business earns more because of it. Revenue per employee, and payroll as a share of revenue, are the two quickest checks: the revenue per employee calculator runs both before and after a planned hire. In services businesses the link is more direct: billable hours at the bill rate must cover the cost per productive hour with margin to spare, and the utilization rate calculator shows what share of available hours is actually billed. A role at sixty percent utilization costs the same as one at eighty; it just earns a quarter less.
Putting the budget together
For each role: salary, contributions, benefits and overheads give the yearly cost; weeks and productive share give the cost per useful hour; expected raises and leave adjust next year's figure; a turnover allowance covers the leavers you will have; and revenue per head or utilization says whether the team is paying for itself. The Team Cost & Headcount Planner keeps all of it per person in one workbook, including a hiring plan prorated for the year and the turnover calculation, so the budget updates when a salary or a start date changes.
Common mistakes
- Budgeting salary only. The on-costs are not optional and are often a third of the total.
- Dividing by 2,080 hours. Leave and non-productive time make the real hourly cost noticeably higher.
- Ignoring turnover. One leaver in a team of five can cost more than the raise that would have kept them.
- Hiring for capacity nobody has sold. Check utilization and revenue per head before adding a seat.
