Where the money goes

Social insurance takes ₩204,050 a month and income tax (with the 10% local income tax on top) takes ₩25,010. The largest single deduction is National Pension at ₩99,750. Over a full year that is about ₩2,448,600 in insurance and ₩300,120 in tax.
Income tax is low at this salary: the withholding table takes only ₩22,740 a month. Most of what you pay goes to the social insurances, which also earn you health cover and pension rights.
Compared with the minimum wage
₩2,100,000 a month works out to ₩10,048 an hour for a full-time job (209 paid hours a month, including weekly holiday pay). That is below the 2026 minimum wage of ₩10,320 an hour, which is ₩2,156,880 a month for 40 hours a week. If you work full time, check your contract with your employer or the labour ministry (call 1350). A lower salary can be legal if your contract has fewer hours.
What a raise is worth
Moving up to ₩26M a year adds ₩66,666 to your gross pay but ₩58,116 to your take-home pay each month — you keep about 87% of the raise. At ₩24M a year you would take home ₩86,750 less a month.
Severance at this salary
After working at least one year (15+ hours a week), you are owed severance pay (퇴직금) when you leave: roughly one month of average pay for each year — about ₩2,100,000 per year at this salary, more if you get bonuses. It must be paid within 14 days of your last day and is taxed separately. Work out your exact severance →
