Editorial Policy — How We Verify Numbers
Most of our tools and articles deal with money and law — take-home pay, severance, social insurance, unemployment benefits, tenancy. In these topics a single wrong number costs the reader real money. So we publish the process we use to check them. We did not write down any rule we do not actually follow.
1. Numbers come from primary sources
Rates, deduction tables and caps are never copied from other calculator sites. We read the statute or the agency that administers it.
| Topic | Where we check |
|---|---|
| Labour standards (leave, overtime premiums, weekly holiday pay) | Labor Standards Act, via the national statute database |
| Severance pay | Employee Retirement Benefit Security Act and its enforcement decree |
| Retirement income tax, year-end settlement | Income Tax Act + National Tax Service guidance |
| Four major insurances | National Pension, Health Insurance, Employment Insurance, COMWEL |
| Unemployment benefits | Employment Insurance Act + the Employment Insurance service |
| Brokerage fees, tenancy | Licensed Real Estate Agents Act, Housing Lease Protection Act |
Every article ends with a “Legal basis · Official sources” section linking what we read. Our standard is that a number without a link does not get published.
2. The calculators and the articles must agree
If a constant in the calculator code and a figure in an article drift apart, the site contradicts itself and the reader cannot tell which is right. It is a common failure and an avoidable one.
So we open the calculator source before writing and match its values. When a rate changes, the code and the articles are changed together. Changing only one side is treated as a defect.
For 2026: National Pension 4.75%, Health Insurance 3.595%, Long-term Care 13.14% of the health premium, Employment Insurance 0.9%, pension income ceiling ₩6.37m/month, tax-free meal allowance ₩200,000/month, minimum wage ₩10,320/hour — these values are identical everywhere on the site.
3. Automated checks before every deploy
- Any broken internal link (we do not deploy if one exists)
- All structured data (JSON-LD) parses
- No indexable page is unreasonably thin
- No duplicate titles, descriptions or H1s
- No unfinished placeholder text left on a public page
- Sitemap matches the actual pages
Tools are also opened in a real browser and used before release — we enter values, press the button, and check that the result appears, that nothing overflows horizontally on a phone, and that no JavaScript error is thrown.
4. What we refuse to do
| We do not | Why |
|---|---|
| Scrape data from other sites | We cannot stand behind a source we did not read, and we would inherit its errors |
| Fill in numbers we have not verified | If we do not know, we say it needs checking. We do not invent plausible values |
| Pad articles to hit a word count | That spends the reader's time and returns nothing |
| Give individual advice | We summarise general rules. Individual cases belong to the competent authority or a professional |
| Store what you type | Most calculations finish inside your browser. Exceptions are stated in the privacy policy |
5. If you find an error
Rules change and we get things wrong. Corrections from readers are the fastest way to keep this site accurate.
- Tell us through the contact page. Which page and which number is enough.
- A link to the statute or agency page helps us confirm it faster.
- Once confirmed we fix the page and update its “Updated” date. If the calculator code is affected, we change that too.
Every article shows a published and updated date. These are topics that change, so please weigh an older date accordingly.
6. Advertising disclosure
- This site is funded by Google AdSense advertising.
- Ads are placed automatically by Google. Advertisers have no influence over our articles or calculation results.

- Cookie use related to advertising is described in our privacy policy.
7. Who makes this
The site was started by someone who used to build internal tools at work. More background is on the about page.
We are not lawyers or tax accountants. Where interpretation is contested we say so rather than assert, and point you to the competent authority. Everything here is reference material and not legal or tax advice, as set out in our disclaimer.
※ This document describes only what we actually do. If we stop being able to follow a rule, we will change this page.
