Tool pages show the inputs, formula or method, examples, benchmarks, and limitations whenever possible.
Accuracy
Formulas, methods, assumptions, and limits are shown on each tool.
Toolkit Shelf calculators and tools are meant for quick estimates, comparisons, drafting, checks, and everyday planning. Tool pages include the relevant formula or method whenever possible.
Results can change based on rounding, assumptions, local rules, tax treatment, fees, source data, or personal circumstances. Money, health, housing, tax, legal, and business tools are planning aids, not professional advice or approval decisions.
Benchmarks are treated as broad planning ranges unless a page explicitly names a source for that range. When a sensitive page uses an outside reference, the source note appears near the details section so the assumption can be checked.
Money, tax, health, and housing pages use source notes when a public reference helps explain a formula, limit, or warning.
Pages distinguish formula visibility, source notes, planning estimates, and user-entered assumptions. Expert review is not implied unless the page says so.
The contact page is the correction path for formula issues, confusing wording, missing assumptions, or outdated benchmarks.
Review labels
Review labels used on pages
These labels describe what is visible on the page. They do not imply expert review unless a page says so directly.
A calculator page shows the calculation formula and has been checked against the inputs and worked example shown on the page.
A generator, checker, analyzer, converter, or template page explains the visible method or rules used to create the output.
The page links to a public reference when an outside formula, benchmark, rule, or warning helps explain the result.
The page explains the user-entered assumptions even when no outside source is needed for the tool.
The result is for scenario planning and comparison, not a quote, approval, diagnosis, filing result, or professional decision.
The page has not been labeled as reviewed by a licensed expert, clinician, tax professional, engineer, attorney, or financial advisor.
Use outputs for planning and comparison. Rates, withholding, fees, eligibility, and local rules can change the real result.
Health calculators are screening or planning tools. They do not diagnose conditions or replace medical or nutrition guidance.
Material calculators estimate quantities and waste. Structural design, permits, site conditions, and code compliance require a qualified professional.
Pricing, invoice, runway, and sponsorship outputs are scenario estimates. Contracts, rights, taxes, payment timing, and market demand can change decisions.
