Salary is only one part of employee cost
An employee’s base salary is not usually the full economic cost to the employer. Bonus, employer payroll charges, benefits and other recurring costs can add to the annual amount. Recruitment, onboarding and exit payments create additional costs that should not be confused with the continuing salary run rate. This calculator makes those components visible rather than hiding them inside one unexplained percentage.
Use single-employee mode for an annual cost estimate, employee groups for teams with different compensation assumptions, and headcount planning for changes during the year. The outputs are positive expenses. They are not take-home pay, employee income tax or a payroll remittance schedule. A useful finance estimate requires a clear scope before it requires a complicated formula.
The recurring employee-cost formula
Base salary cost equals average FTE multiplied by annual salary per FTE. Bonus equals that base multiplied by the bonus percentage. Payroll taxes and benefits equal base salary plus bonus, multiplied by the user-supplied employer percentage. Other recurring cost per FTE is multiplied by average FTE and added separately. This last field can capture costs not already included in the percentage.
For one full-time employee with salary of 100, bonus of 10% and employer burden of 20%, salary is 100, bonus is 10 and burden is 22. Recurring annual cost is 132 before other additions. Its annualized monthly equivalent is 11. Enter all amounts in the same currency and scale, so this example could equally represent thousands.
Choose your own payroll and benefit assumptions
Employer costs depend on location, compensation structure, benefits policy, employee category and the specific planning purpose. This tool intentionally does not infer statutory rates from a selected currency. Choosing EUR does not select the employment rules of a particular country. Obtain the relevant assumptions from your payroll team, advisers or company planning data and enter them explicitly.
The burden percentage here applies to salary plus bonus. If a benefit is already included in that percentage, do not enter it again as another recurring cost. If a fixed benefit is more accurately modeled per employee, place it in the separate field and adjust the percentage accordingly. The calculator does not apply a further automatic burden to severance, hiring fees or termination costs; include any associated amounts deliberately.
FTE is a capacity measure, not always a person count
Full-time equivalent expresses working capacity relative to one full-time role. Two people working half time can represent one FTE. Salary per FTE should therefore describe the full-time annual equivalent, not the part-time employee’s already reduced cash salary. Multiplying a part-time salary by a fractional FTE again would understate the intended cost.
For a stable team, enter the FTE level expected throughout the period. If part-time arrangements, unpaid leave or vacancies change materially, use an average that reflects the available information. The calculator accepts fractional FTE. In its compact hiring plan, hires and exits are also FTE equivalents; per-hire and per-exit costs consequently use that same simplified volume basis.
Employee groups make the estimate more useful
Teams often have different salaries, bonus structures and benefit costs. Employee-group mode supports up to twelve groups, each with its own FTE, annual salary, bonus, burden and other recurring cost. Group names are descriptive only. Adding a new group does not change the assumptions of existing groups, and switching methods preserves entered values during the page session.
For example, ten FTE at salary 100, bonus 10% and burden 20% cost 1,320 annually. Five support FTE at salary 60, no bonus and burden 20% cost another 360. The combined total is 1,680 for fifteen FTE, or recurring cost of 112 per FTE. This weighted result is more informative than averaging the two salary rates without considering team size.
Opening, closing and average FTE are different
Closing FTE equals opening FTE plus hires minus exits. Recurring personnel cost, however, depends on the capacity employed during the year, not merely the closing position. Hiring two people in December should not automatically create two full years of salary expense. Conversely, using closing FTE after departures can understate costs incurred earlier in the period.
Without exact dates, the default assumes all net changes take effect at mid-year: average FTE = opening FTE + 0.5 × hires − 0.5 × exits. Start-of-year and end-of-year alternatives are available. These are explicit annual approximations, not a detailed event calendar. Simultaneous hires and exits are not assigned different dates, so a rapidly changing workforce may require the full model’s dated schedule.
Worked hiring-plan example
Start with ten FTE, hire two and record one exit. Closing FTE is eleven. Under the mid-year convention, average FTE is 10.5. At salary 100, bonus 10% and burden 20%, base salary cost is 1,050, bonus is 105 and payroll burden is 231. Recurring personnel cost is therefore 1,386 before other recurring expenses.
Assume hiring cost of 5 per hire, termination cost of 3 per exit and two months of severance. Hiring costs are 10, termination costs are 3 and severance is 1 × 2 × 100 ÷ 12, or approximately 16.67. Total annual personnel cost is approximately 1,415.67. The recurring monthly equivalent remains 115.50; it excludes these one-time additions.
Keep hiring, onboarding and exit costs separate
Hiring cost is hires multiplied by cost per hire. Termination cost is exits multiplied by cost per exit. Severance is exits multiplied by severance months and annual salary divided by twelve. These amounts are not reduced by the annual FTE timing weight because a fee or exit payment can arise once even if the employee works for only part of the year.
Single-employee mode lets you add one hiring event and one exit event as optional costs. Its recurring amount remains a full-year run rate; use headcount-plan mode when salary itself should be time-weighted. Include recruitment or onboarding costs only once, and distinguish a direct incremental cost from an allocation of existing staff time. Those choices determine what “fully loaded” means in your analysis.
Turn the estimate into a personnel forecast
Build the forecast from operational drivers: needed capacity, expected salary levels, bonus policy and realistic hiring or attrition assumptions. A salary increase changes cost per FTE, while new roles change the quantity of FTE. Keeping those effects separate makes it easier to explain a budget variance and to see whether a higher expense total reflects growth, pay inflation or a different team mix.
Some teams can be connected to business volume, such as revenue per consultant or support capacity per customer. A driver relationship is an assumption about required staffing, not a guarantee of revenue. In the Revenue Model and the full financial model, check the commercial and capacity assumptions together rather than assuming every additional hire immediately creates sales.
Personnel expense, cash and the financial statements
An annual expense estimate does not establish the exact cash-payment dates. Bonuses may be accrued before settlement, payroll liabilities may carry over a reporting date, and hiring or exit payments can occur at different times. The monthly output is annual recurring expense divided by twelve, not a promise that each month’s payroll cash flow will be identical.
Personnel costs also need an accounting classification. Some belong in production costs, others in selling or administration; certain activities may require a different treatment under the applicable accounting policy. Avoid adding the total again if salaries are already embedded in another cost line. The Three-Statement Model connects personnel assumptions to the wider forecast while keeping expense recognition and cash timing conceptually distinct.
Checks before using a fully loaded cost estimate
Confirm that salary is annual, bonus and burden are entered as percentages, and FTE is measured consistently. A value of 20 means twenty percent, not 0.20 percent. Exits cannot exceed opening FTE plus hires in the planning period. Zero average FTE makes a per-FTE ratio unhelpful, even if one-time exit costs still exist. The tool reports that limitation instead of inventing a ratio.
Keep a short record of assumptions and exclusions: benefit scope, annual timing convention, hiring volumes, severance basis and currency scale. Do not present an illustrative employer percentage as a legal rate. For a hiring decision, combine this estimate with expected contribution, financing capacity and organizational needs. The calculation improves transparency; it does not decide which role should be hired or removed.
Frequently asked questions
Is this a country-specific payroll calculator?
No. It uses the employer burden and benefit assumptions you provide. It does not calculate local statutory contributions, personal taxes, net pay or payroll compliance obligations.
Does monthly cost include hiring and severance?
The monthly result is recurring annual personnel cost divided by twelve. One-time costs appear separately and are included in total annual personnel cost, making the distinction clear.
How is average cost per FTE calculated?
Recurring annual cost is divided by average FTE. One-time costs are excluded from this run-rate measure. If average FTE is zero, the ratio is omitted and a clear explanation is shown.
