Korean employment law gives you rights that may not exist back home — an extra paid day every week, statutory severance after one year, paid leave that accrues monthly. These tools apply the law and the official rate tables directly, and show you the working.
Korean payroll runs on rules that are published in Korean, updated every year, and rarely explained anywhere else. The withholding table that decides your income tax is a 588-row government document. The weekly holiday allowance has no equivalent in most countries, so nobody thinks to ask about it. Severance is a legal entitlement rather than a benefit your employer chooses to offer.
These tools apply the actual rules rather than a rough approximation, and each page explains where the number came from. If your payslip disagrees with the result, that gap is worth asking your employer about.
