Methodology and Sources

Trond Nesse — Publisher, Earning One

This page explains how Earning One builds calculators and guides, what source types are used as baseline references, and where the limits of the site begin. The goal is transparency: readers should be able to tell what is modeled directly, what is simplified, and what should be checked against an official source before acting on it.

Core publishing approach

Earning One is built around practical decision questions rather than broad lifestyle finance coverage. Most pages sit at the intersection of pay, time, withholding, inflation, and household pressure because that is how these issues appear in ordinary life. The site tries to make those connections explicit instead of treating each topic in isolation.

Pages are intentionally compact compared with a large finance portal, but the target is still substance: a page should help a reader frame a clearer comparison, understand a tradeoff, or spot a hidden assumption that affects a real decision.

How calculators are built

The calculators on Earning One do not claim to be official payroll, tax, or customs engines. They are planning tools. That means the formulas are intentionally transparent and user-adjustable rather than fed by a large hidden ruleset.

The salary calculator uses user-entered hourly pay, hours, weeks, overtime assumptions, and a blended withholding percentage.
The inflation calculator uses user-entered salary and inflation assumptions to show erosion in buying power and break-even income.
The tariff calculator separates nominal tariff rate from pass-through rate so readers can model scenarios instead of assuming one policy headline equals one retail outcome.

This approach is useful for comparisons and planning because it keeps the logic visible. It is less useful when a reader needs an exact payroll result, a tax filing output, or a legally binding customs figure. In those cases, the correct move is to use the relevant official or employer-specific source.

Primary source categories

Earning One uses primary public references as baseline anchors when building or reviewing content. These references are not treated as complete replacements for judgment, but they set the standard for definitions and context.

IRS Tax Withholding Estimator for withholding context and why paycheck estimates can differ from final tax outcomes.
U.S. Department of Labor overtime guidance for overtime framing and work-hour assumptions.
Bureau of Labor Statistics CPI materials for inflation background and CPI interpretation.
U.S. Customs and Border Protection trade resources for tariff process context.
U.S. International Trade Commission tariff schedule resources for tariff classification background.

Why the site still uses simplified models

Official systems are usually more detailed than a planning tool should be. The site simplifies on purpose so a reader can understand what changes the answer. A withholding estimate that exposes the percentage assumption is often more useful in early decision-making than a black-box figure that looks precise but cannot be stress-tested.

The same principle applies to inflation and tariff pages. Real households face category-specific inflation. Real import costs depend on contracts, exemptions, logistics, and market power. The site makes those limits explicit because clarity about uncertainty is part of the value.

How guides are written

Guides are built to extend the tool output, not duplicate it. A useful guide should explain what the number means, when it becomes misleading, and how to use it in an actual conversation or decision. Examples include comparing job offers, evaluating a raise, understanding why net pay is lower than expected, or translating inflation into household planning.

The writing style stays deliberately plain. A page should be understandable without specialized finance language. Where a concept is inherently technical, the site tries to translate it into questions a reader can actually use.

Update and correction standard

Pages are reviewed when assumptions age badly, official context changes, links stop working, or readers point out a weak explanation. Corrections are encouraged through the Contact page. A correction request is most useful when it includes the page URL, the exact line or assumption being questioned, and a source or real-world example that shows the gap.

What the site is not

Earning One is not a substitute for tax software, payroll records, legal advice, or a licensed financial planner. It is also not a broad market-news site. The value of the site should come from practical interpretation and decision support, not from trying to compete on volume or headline churn.
