About

Korea Data Tools is a small set of free calculators in English for foreigners in Korea. It is part of zinnote.kr, which also runs ZIN Money and its English Korea Life Guide.

How the numbers are made

Every tool runs in your browser. Unit conversions use exact definitions (for example, 1 pyeong = 400/121 m²). The salary calculator uses the 2026 contribution rates published by the Korean government and explains its assumptions on the page. Rates change every year, so each tool shows the date its numbers are based on.

Not professional advice

Results are estimates to help you understand Korean numbers. For decisions about contracts, taxes or visas, check with your employer, the National Tax Service, or a professional.
