Published standards
Editorial policy
A calculator is useful only when a reader can understand where its numbers came from and where they stop applying. These standards govern every public PayrollFixPro tool.
Scope before coverage
Every calculator must identify its jurisdiction and calculation model. We do not describe a federal weekly overtime model as state-specific, a planning estimate as a payroll register, or a user-entered rate as an official rate.
Source hierarchy
Regulated limits and rates should cite a current primary source such as the IRS, US Department of Labor, Singapore CPF Board, or IRAS. Secondary sources may help explain context but do not replace the controlling source. Each tool lists the effective year or review date relevant to its formula.
Formula and testing standard
Inputs should map directly to the calculation described on the page. Before publication, a tool is checked with ordinary examples, zero values, threshold values, and annual caps. Outputs avoid unsupported precision and distinguish user assumptions from official constants.
Original value standard
We do not publish a new page merely by replacing a job title, country, or keyword in a common template. A page must solve a distinct task, explain a distinct model, or provide a meaningfully different workflow. Repetitive pages are consolidated or removed.
Corrections and updates
Reports should identify the page URL, disputed statement or result, reproducible input example, and an authoritative source when available. Confirmed material errors are prioritized over new content. The corrections page provides the current reporting channel.
Commercial independence
Advertising or future affiliate relationships do not change calculator formulas or source selection. A paid relationship must be labeled. PayrollFixPro does not currently rank providers through undisclosed payments, and generic outbound recommendation boxes are not part of the maintained calculator pages.
Professional-advice boundary
PayrollFixPro does not provide individualized legal, tax, accounting, payroll, or financial advice. A result is a planning aid and must not be the sole basis for a payment, filing, regulated decision, or contract interpretation.
