Editorial & corrections policy
How Everyday explains calculation methods, distinguishes assumptions from official rules and handles corrections.
Explain the model, not just the answer
We distinguish formulas from assumptions. A fixed-rate amortization formula is not a lender quote, a constant-return projection is not an investment forecast, and a screening equation is not a diagnosis. We publish the inputs, calculation method, exclusions and examples needed to understand each result.
Sources and tax updates
For rules set by an agency, we prioritize official sources such as the IRS, state revenue departments, CDC and NIST. Tax parameters are labeled by tax year; support for one year or state does not imply support for every jurisdiction. Review dates on the tax methodology describe the parameter review, not a guarantee that all future changes are already reflected.
Authorship and review
GEOINNOVATION CO., LTD is responsible for this site’s published content. Educational explanations are provided by the Everyday editorial team; no professional license or independent expert certification is implied. Automated checks exercise the models and input validation, but cannot establish that every real-world tax or financial situation is supported.
Corrections
Report an issue at hoons9096@gmail.com, ideally with a public source and a reproducible example. We assess the applicable year and scope, correct confirmed errors and update the relevant explanation. We may narrow or disable a tool when a reliable result cannot be provided. We do not promise a response or correction deadline.
Advertising and independence
Any future advertising must be identifiable and must not be presented as a calculation result or official recommendation. Advertising does not make an illustrative rate or product suitable for a particular user. We do not promise AdSense acceptance or a particular search ranking.
