Editorial Policy

Last updated: May 5, 2026

Content Standards

Each calculator page is built around a specific user decision. We avoid publishing generic finance filler and focus on practical explanations, examples, and tradeoffs tied to the tool on the page.

Finance content can affect real decisions, so calculator pages must explain assumptions, avoid guarantees, and remind users that results are estimates. When a page covers taxes, borrowing, investing, or retirement, it must avoid personalized advice and point users toward qualified professionals for individual decisions.

Formula Review

Calculator formulas are reviewed for reasonableness before publication. When a tool uses a common convention, such as amortization math, the 4% retirement rule, annual percentage rate, or future value calculations, the page explains the convention and the limitation.

Review focuses on whether inputs are clearly labeled, defaults are reasonable, edge cases are handled, and the result text does not overstate certainty. Financial calculators can make a number feel more precise than it really is, so each page should explain what the math includes and what it leaves out.

Sources And Assumptions

CalculateThisNow favors common, transparent formulas over hidden scoring systems. For example, loan pages use standard amortization math, payoff pages simulate monthly interest and principal reduction, and retirement pages explain simplified safe withdrawal and future value assumptions.

When a page uses a rule of thumb, the rule is presented as a planning shortcut rather than a promise. The page should make clear that taxes, fees, lender terms, investment returns, inflation, insurance costs, and user behavior can change real-world outcomes.

Corrections

If a reader reports a formula issue, unclear explanation, or broken link, we review the page and make corrections when appropriate. Send correction requests to [email protected] with the page URL and details.

Useful correction reports include the page URL, the inputs used, the output shown, and why the result seemed incorrect or unclear. We prioritize issues that affect calculator math, user understanding, accessibility, broken links, and legal or privacy clarity.

Independence From Personal Advice

The site publishes educational calculators and guides, not individualized advice. Calculator results should not tell a user what product to buy, what investment to choose, or whether a specific financial decision is right for them. When a topic is likely to depend on personal circumstances, pages point users toward qualified professionals.

Update Practices

Pages are updated when formulas, assumptions, examples, or legal disclosures need revision. Date stamps are used on legal and policy pages so users can see when those pages were last reviewed.
