Editorial standards & review process
PayoffTool publishes calculators and guides about money decisions, so accuracy and independence are not optional. This page explains how our content is made, checked, and corrected — and how we stay accountable to you.
Our promise to readers
- Accuracy first. Every calculator uses documented, industry-standard formulas you can verify on our methodology page.
- Plain, honest language. We explain trade-offs, not just outputs, and we flag assumptions and limitations clearly.
- Reader interest over advertiser interest. Advertising keeps the site free, but ads never influence the math, our recommendations, or what we publish. We do not accept payment to alter results or reviews.
- Privacy by design. Calculations run in your browser; we never receive the figures you enter. See our privacy policy.
How we research and write
Guides begin with the standard financial mathematics behind the topic (amortization, interest accrual, break-even analysis) and are written to be understandable without jargon. Where we cite a rule of thumb, we explain the reasoning so you can judge whether it applies to your situation. We favor worked examples over vague generalities.
How we review before publishing
- Calculation check. New or changed calculators are validated against independent references — typically a spreadsheet's
PMT/amortization functions — before release. - Clarity check. Every guide is read for accuracy, balance, and readability, and to confirm that assumptions and disclaimers are present.
- Link and consistency check. We verify internal links, cross-references, and that guidance is consistent across pages.
Keeping content current
We review our calculators and cornerstone guides periodically and whenever the underlying logic changes. When we make a substantive update, we revise the "last reviewed" date on the page. Financial conditions change, so we treat our content as living documents rather than set-and-forget pages.
Corrections policy
We correct errors promptly and transparently. If you spot a mistake — in a formula, an example, or a guide — please contact us. We investigate every report, fix confirmed errors quickly, and update the review date to reflect the change.
Not financial advice
PayoffTool is an educational resource. Our tools and articles provide general information and estimates, not personalized financial, tax, or legal advice. For decisions specific to your situation, consult a qualified professional. See our terms for details.
