Net salary calculator

Your net salary is the amount that actually reaches your account. Social and health insurance contributions and the income tax withheld are deducted from the gross salary agreed in your contract.

First the employee's contributions are worked out from the gross salary: 9.4% social insurance and 4% health. What remains is the tax base. The tax-free allowance is subtracted from it and the rest is taxed at 19%, or 25% on the part above the statutory threshold. The net salary is gross minus contributions minus tax.

• H: the gross salary agreed in the contract
• O: the employee's contributions: 9.4% social insurance and 4% health
• T: the income tax withheld after the tax-free allowance is deducted

The contributions and the maximum assessment base match the Social Insurance Agency figures effective from 1 January 2026. The tax amounts come from Slovak Financial Directorate notice 31/DZPaU/2025/I and are derived from the subsistence minimum of €284.13: the allowance is 21 times it, the higher-rate threshold 154.8 times.

Net pay as a share of gross falls as income rises: at lower salaries an employee hands over about a fifth, at higher ones close to a third. The tapering allowance and the higher tax rate above the threshold are what cause it.

• An employee in an employment relationship with a single employer.
• The tax-free allowance is applied monthly through the employer.
• The calculation excludes the child tax bonus and the allowance for a spouse.
• It excludes work agreements, separately taxed bonuses and supplementary pension contributions.
• Social insurance is charged up to a maximum assessment base; health insurance has no ceiling.

• Confusing the gross salary with the total cost of employment. The employer pays its own contributions on top of the gross.
• Assuming the higher tax rate applies to the whole income. Only the part above the threshold is taxed at it.
• Claiming the tax-free allowance with two employers at once. The law does not allow it, and it leads to a tax bill later.
• Expecting net pay to rise in step with gross. Because the allowance tapers, it rises more slowly.

• Inflation
• Real vs. nominal return
• Passive income
