Editorial Policy

Our goal is to help consumers understand mortgage calculations and home-financing concepts using clear explanations, transparent assumptions, and practical examples.

Content should help readers understand what a calculation means, what assumptions affect it, and where an estimate may differ from an actual lender quote or real-world cost.

We aim to publish information that is accurate, understandable, and appropriately qualified. Financial concepts can vary based on loan program, lender, borrower, location, property, and market conditions, so we avoid presenting estimates as guaranteed outcomes.

Calculator logic and educational content should be consistent with the methodology documented for the Site. Important assumptions and limitations should be disclosed where they could materially affect a user's interpretation of a result.

See our Methodology page for more information.

When mortgage rules, legal requirements, government programs, or similar factual claims require external support, we prefer authoritative primary sources such as government agencies, regulators, government-sponsored enterprises, and official program documentation.

Secondary sources may be used for context, but they should not replace authoritative sources when the primary source is reasonably available.

MortgageCalculator.is may display mortgage rate tables, lender offers, referral links, advertisements, or other commercial content. Compensation may be received when users interact with certain offers or third-party services.

Commercial relationships should not change the mathematical formulas used by our calculators or require us to present an estimate as a guaranteed lender result.

Mortgage offers or rates displayed by third-party providers are separate from the interest-rate assumption entered into our mortgage calculator.

Third-party offers may contain their own eligibility requirements, APRs, points, fees, loan terms, and other conditions. Visitors should review the provider's disclosures before making a financial decision.

If we identify a material factual or calculation error, we aim to correct it promptly. Minor wording, formatting, grammar, and presentation changes may be made without a formal correction notice.

Readers who believe they have found an error can notify us through our Contact Us page.

Mortgage information can change over time. We may review and update pages when formulas, program rules, market conventions, source materials, or site functionality change.

An older publication or update date does not necessarily mean that a mathematical formula is outdated, but time-sensitive financial information should be reviewed when appropriate.

Content on MortgageCalculator.is is provided for educational and informational purposes. It is not individualized financial, lending, tax, legal, accounting, or real estate advice.
