Turkey-Specific Tools

Tools prepared for Turkey-specific needs like salary, tax, severance, leave, and IBAN validation, all in one place.

This collection brings together the tools built specifically for Turkish regulations and everyday Turkish paperwork. Net-Gross Salary Calculator and Income Tax Calculator help make sense of a salary offer, while SGK Premium Calculator, Severance Pay Calculator, Notice Pay Calculator, and Overtime Pay Calculator speed up calculations that come up often in Turkish employment. Annual Leave Calculator shows the leave days earned based on seniority, and EYT Rough Check gives a rough first read based on your social-security start date — the official SGK record is what ultimately decides it. VAT Calculator covers everyday commercial transactions. Turkish Character Fixer repairs garbled ç, ş, ğ, ı characters, Turkish ID Number Validator and Turkish IBAN Validator check whether a number is algorithmically well-formed (not whether it's actually registered or active), and GPA Converter translates between the Turkish grading scale and the 4.0 scale.

What are these tools good for?

Generic calculators don't know Turkish labor law, Turkish social security (SGK) deductions or how a Turkish ID number is built. These tools follow those local rules. They're most useful for people working or hiring in Turkey.

Salary and tax

The Net-Gross Salary, SGK Premium and Income Tax Calculators are often used together: weighing a job offer, checking take-home pay after a raise, or seeing why pay drops when you move into a higher bracket later in the year. The VAT Calculator is a daily tool for anyone who invoices or quotes prices.

Leaving a job and work rights

  • Severance Pay Calculator: Kıdem tazminatı is statutory severance, roughly 30 days' gross pay per full year after at least one year of service.
  • Notice Pay Calculator: A notice period of 2, 4, 6 or 8 weeks depending on seniority.
  • Annual Leave Calculator: Legal leave days by years of service.
  • Overtime Pay Calculator: Hours over 45 a week are paid at a 50 percent premium.
  • EYT Rough Check: EYT is an early-retirement arrangement for people first insured before 8 September 1999.

Validation and text

The Turkish ID Number and IBAN Validators catch typos on forms. An ID number has 11 digits and the last two are check digits. A Turkish IBAN starts with TR and is 26 characters long. The Turkish Character Fixer repairs garbled letters like "ş" or "ı" that appear when encodings get mixed up. The GPA Converter turns a 100-point average into the 4.0 scale.

A sample workflow

A small company is hiring. The ID number and salary IBAN from the onboarding form go through the validators. The Net-Gross Salary Calculator turns the agreed net pay into gross, and the SGK Premium Calculator shows the full employer cost. If names in a staff list exported from an old system look broken, the Turkish Character Fixer cleans them up.

Tip

Validators only confirm that a number is well formed. They can't tell you it belongs to a real person or account. Salary, tax and severance figures depend on yearly parameters, so check current values with GİB, SGK or e-Devlet.
