Group 1: Salary & Taxes – Calculate correctly, receive fully.

Calculate Gross salary ↔ Net salary

This is the most frequently used tool in the collection.

This feature is useful for both employees negotiating salaries and HR departments when preparing payroll.

Calculating personal income tax (PIT)

Not limited to office salaries, the personal income tax calculator supports many types of income: salaries, business income, real estate, securities, etc. The 5-tier progressive tax rate schedule, applicable from 2026, is fully updated, providing accurate results instantly.

Calculating pension in 2026

This tool forecasts monthly pension amounts based on the total number of years of social insurance contributions, the benefit rate (45%–75%), the average monthly salary used for social insurance contributions, and the new retirement age. Those approaching retirement age can proactively plan starting today.

Group 2: Social and Labor Insurance – Understanding Your Rights

Unemployment benefits

This tool calculates the monthly unemployment benefit amount as 60% of the average salary of the 6 months prior to losing the job, and also determines the number of months of benefits and the total benefit received. Newly unemployed workers can immediately check their eligibility for support.

One-time social insurance payment

Many people are unsure exactly how much they will receive when withdrawing their social insurance contributions in a lump sum. This tool calculates the details based on the latest price adjustment coefficients, supports both mandatory and voluntary social insurance, and includes a breakdown of each year's insurance contributions.

Maternity leave

The 2024 Social Insurance Law regulates many maternity benefits. The tools include all seven types of benefits: childbirth, convalescence, prenatal check-ups, miscarriage, and other special cases – ensuring mothers don't miss out on any benefits.
