About SafeCalc

SafeCalc is a free set of calculators for numbers people in South Korea check often: monthly pay, severance pay, weekly holiday pay, loan interest and age.

Calculated in your browser

The amounts and dates you enter are not sent to a server. All calculations run in the browser you are using, and nothing is kept after you close the page.

Where the numbers come from

Social insurance rates, tax rates and the minimum wage follow official notices and laws, and are updated when they change. Each calculator explains how it works at the bottom of the page.
