SEMSIN: Korean calculators with their working shown
A collection of Korean calculators for employment rights, take-home pay, taxes, benefits, housing, and financial decisions.
- For
- Korean workers checking pay, leave, severance, or benefits
- Worth noticing
- The homepage dates its source checks to 2026-09-19 and says it separates estimated income tax from figures checked against official simulators.
Field notes
SEMSIN frames the calculators as rule-based checks, not just number generators: the homepage says it shows which constants and rules feed each result and marks where an estimate begins. Its examples include checking whether a variable loan rate could reverse a repay-versus-invest comparison, and distinguishing an unverified housing notice from one with no asset requirement. The site says its constants were checked against primary sources on 2026-09-19; actual calculator screens were not included in the extract.
