It supports popular types of employment: employment contract, mandate contract and B2B model with a simple tax simulation. The bid and parameter values are fully configurable in the form panel, so you get a result that is consistent with the current rules and your situation.
How the calculator works and what it takes into account
- Conversion of gross to net and net to gross with the option the full cost of the employer.
- Selection of the type of contract: employment contract, mandate contract, B2B with a simplified cost model.
- Configurable parameters: acquisition costs, tax relief, tax rate, social and health insurance contributions, PPK and other deductions.
- Breakdown of the result into individual components and a clear summary.
- Support for different salary ranges and simple annual scenarios.
Formulas and theory
Remuneration structure - core calculations
Gross remuneration includes all components on which contributions and tax are calculated. Net remuneration is the amount to be paid after deducting contributions and income tax advances in accordance with the selected contract type and parameters.
- Calculate the employee's social contributions from the base: retirement, disability, sickness benefits according to configurable rates.
- Health contribution basis = gross minus the employee's social contributions.
- Health contribution = health base × health rate.
- Tax base = gross minus employee's social contributions minus tax deductible costs.
- Tax advance = tax rate × tax base minus monthly relief (if applicable), after rounding required by regulations.
- Net salary = gross minus employee's social security contributions minus health insurance contribution minus tax advance minus other deductions (e.g. PPK, voluntary).
In the case of the opposite direction, we use iterative conversion. The calculator changes the gross amount so that, after deductions, the given net value is obtained within the given tolerance. Thanks to this, the result is consistent with the parameters of contributions and tax.
Employment contract and mandate
The employment contract standardly covers full social security contributions of the employee and the employer, as well as health insurance and tax advances. A mandate contract may have different contribution configurations depending on the status of the contractor. The calculator allows you to set the required contributions and tax-deductible costs according to the selected scenario.
B2B model - simplified approach
In the B2B model, net is often understood as the amount after tax and entrepreneur's contributions. In the calculator, you enter monthly revenues, costs and parameters of tax and contributions. The tool calculates the result after paying contributions and tax, and allows comparison to the UoP simulation.
Employer's total cost
The calculator can calculate the employer's total cost. This is the sum of gross remuneration and contributions financed by the employer. Components and rates are configurable and depend on the selected contract type.
How to use the calculator - quick steps
Step 1 - select the mode
Select the conversion direction: gross to net or net to gross. Indicate the type of contract: employment contract, mandate contract or B2B. If you count the employer's costs, activate the appropriate option.
Step 2 - enter amounts and parameters
Enter the gross or net amount. Adjust your tax deductible costs, tax relief and contributions. If necessary, select PPK or additional deductions.
Step 3 - check the breakdown of components
After conversion, you will see the amounts of individual contributions, the tax advance and the net result. The employer's cost with a breakdown on the employer's financing side is also available.
Step 4 - compare scenarios
Copy the results and compare different settings: different costs of obtaining, no relief, gross to net ratio when changing the basis. The tool will quickly show the impact of changes on your payout.
Calculation examples
Example A - employment contract, gross to net
Assumptions:Gross salary PLN 6,000, standard costs of obtaining, monthly relief applied, social and health insurance contributions according to default settings, without PPK.
- Employee's social contributions: total calculated from gross.
- Health contribution: from the base less social contributions.
- Tax advance: calculated from the basis after the costs of obtaining and taking into account the relief.
- Result:net and employer cost displayed in the broken down results.
Example B - mandate contract, full contributions
Assumptions:Gross remuneration PLN 4,000, full ZUS contributions on the contractor's side, percentage or lump-sum costs as set.
- The result depends on the adopted cost model and the tax rate applied.
- Effect:net presented with details of contributions and advance payment.
Example C - net to gross
Assumptions:Expected salary to be paid PLN 5,000 net, employment contract, standard parameters. The calculator iteratively finds the gross corresponding to the indicated net value.
- After calculation, you will see the suggested gross amount and the employer's cost.
Example D - B2B comparison to UoP
Assumptions:Monthly income PLN 12,000, costs PLN 2,000, contributions and tax as set, without PPK. For comparison, the UoP result for the gross amount of PLN 12,000.
- The calculator will show the result after tax and contributions and a simple difference to the UoP variant.
