About

Calcable is a set of calculators for problems with awkward rules: Korean tax, salary and property math, plus hobby calculators that work anywhere. Everything is available in English and Korean.

Each calculator lists the rates, formulas and the date they were last checked, right on the page. If a result can't be traced back to a rule, we don't publish the calculator.

Results are estimates for reference, not tax or legal advice. Check with a professional or the relevant authority before acting on them. Found a wrong figure? Use the contact page — we verify, fix and update the date.
