Employee cost calculator
Full cost of an employee including contributions and overhead.
Fill in the fields and the result will appear here automatically.
This planning model adds gross salary before employee deductions, employer costs at the supplied rate and overhead for the same period. A 30% rate adds exactly 30% of salary, not one third. The multiple compares included costs with salary and depends on your inputs; it is not an industry norm. The tool does not determine take-home pay, current contribution rates, tax ceilings or cost per productive hour.
How it works
Formula and logic
Contributions = salary × rate ÷ 100. Total = salary + contributions + overhead. The multiple is the total divided by the salary. Salary and overhead must use the same month or year. Calculate tiered rates, assessment ceilings and exemptions separately before entering an effective rate. The tool does not divide the total by working hours. The supplied rate retains the original field range 0–200%, which is not a contribution benchmark.
Example
A salary of 180,000 with 30% contributions and 25,000 of overhead costs 259,000 — 1.44 times the salary. With no added costs, salary 100, rate 0% and overhead 0 give total 100 and multiple 1.
Fields and units
- Gross salary before deductions — $
- Employer contributions — %
- Overhead per period — $
How to use
- — Enter the gross salary for the period.
- — Enter the employer contribution rate that applies on top of it.
- — Enter overhead for the same period as an amount.
- — Use the same period throughout — monthly or yearly, not mixed.
- — Avoid counting benefits or paid leave in both salary and overhead; a fixed expense cannot be carried over as a percentage without checking.

FAQ
Are contributions added to the salary or taken out of it?
The entered rate represents employer costs added to gross salary. Employee deductions are not subtracted. Actual tax, contribution and payslip rules depend on jurisdiction and contract.
What belongs in overhead?
Desk space, equipment, software licences, training, recruitment amortised over the stay. Anything the business would stop paying if the role disappeared.
Why is the multiple useful?
It shows the relative budget under the same rate and cost structure: 259,000/180,000 = 1.4389… . Fixed overhead means the multiple must be recalculated for a different salary rather than carried over automatically.
Does this include paid leave?
Leave is not modelled separately. If annual salary already includes paid absences, do not add them again. Productive-hour cost requires dividing annual included costs by a justified working-hour estimate; there is no universal twelve-paid-months-for-eleven-worked rule.
