Terms of Use

Calcmemo provides free browser-based calculators and explanatory material about Korean units, dates, charges, and public rules. No account is required.

The calculators are designed and tested to produce the stated result for the inputs and assumptions shown. A page that depends on law, a tariff, or an annual rate identifies its source-check date and important exclusions.

Results are still informational estimates, not legal, tax, accounting, employment, immigration, insurance, medical, or financial advice. An authority, employer, utility, contracting party, or qualified adviser may use facts this site does not collect. Their official decision or invoice controls.

You are responsible for checking the current source and the facts of your case before relying on a result for a filing, payment, deadline, contract, benefit claim, or other consequential action.

Electricity tariffs, contribution rates, tax rules, benefit limits, and public-holiday rules can change. A displayed check date records the last comparison made by Calcmemo; it does not promise that the issuing authority has made no later change.

Report a suspected error or outdated source to the contact address below. Corrections take priority over new features.

Google AdSense advertising may appear on the site. Google selects individual ads; advertising does not alter calculator logic or results.

Affiliate shopping links are currently paused. They may be restored later only where they are directly useful and relevant, with a visible commission disclosure on every page where they appear.

Calcmemo links to statutes, notices, tariffs, and other official sites so readers can inspect the source. Those sites are operated under their own terms and privacy policies, and Calcmemo does not control their availability or content.

Calcmemo's explanations and presentation may be quoted in limited part with clear attribution. Do not republish substantial parts of a page as your own. Calculation results are facts and may be used freely.

The site may be unavailable during maintenance, and calculators or explanations may be corrected, added, or removed. These terms may also change; material changes will be posted here with an updated date.
