Understand your pay and the assumptions behind it

Who runs the site?

Moneysalary is operated by one working professional and funded through advertising. It began with the operator’s own need to compare changing salary-tax and social-insurance calculations, and is shared for others with similar questions.

The site is independently operated without professional advice from a tax accountant, labor consultant or financial institution. Tax and insurance information is checked against primary materials from the Korean National Tax Service and relevant insurance agencies. Company salaries and forward-looking scenarios include estimates. Check official sources and qualified advice for actual tax or financial decisions.

Operating principles

• Explain the applicable year, rates and deduction assumptions. Distinguish announcements and proposals from rules already in force.
• Distinguish official rates, a company’s reported average compensation, the site’s own estimates and assumptions entered by a user.
• Keep collection limited. Calculations generally run in the browser. Sending a private message stores its content and an optional reply email on the server. Sharing, advertising and analytics are explained in the privacy policy.

Sources and calculation methods

Main references include the National Tax Service, National Pension Service, National Health Insurance Service and Korea Workers’ Compensation & Welfare Service. Check the source and applicable date on each tool or guide. A reference to an official withholding table does not mean that every estimate reproduces that table: the English salary tool uses the simplified regular-employee model described in its method notes.

Choose the model you need in the calculator overview, or read the English guides for the context behind a calculation.

How company salary estimates are prepared

Company pay by grade and the site’s reference rankings are estimates compiled from public job advertisements, reports, media and community reviews; they are not company-confirmed individual salaries. Separately labeled average employee pay, with its source and business year, is a reported value or calculated from reported total pay and employee counts.

The data provides general context for job seekers and employees. It does not guarantee an actual offer or rank a company’s overall quality. Grade, experience, performance and negotiation can substantially change actual pay. Correction requests are reviewed against supporting evidence; the site does not intentionally retain incorrect information or seek to damage reputations.

How information is checked and corrected

• Check legislation and agency announcements first, and distinguish publication dates, application deadlines and effective dates.
• State whether amounts are gross or net, annual or monthly, and explain assumptions that affect the result. An estimate is not presented as a confirmed payment.
• Preserve guide publication dates. Show a separate modification date when the text, calculation assumptions or sources materially change, rather than changing dates alone.
• Review error reports against evidence and consider appropriate corrections or removal. The site does not operate public comments.

Limits and correction requests

All results are general reference estimates. Actual taxes can differ with deductions, credits, household eligibility and employer-specific exempt pay. Use National Tax Service resources or professional advice for tax decisions. If a formula, rate or company figure is wrong, send a private report identifying the source and issue. Reasonable correction and removal requests are reviewed. The terms of use explain the service limits and permitted use of its content.
