Our standard

Every tool should give a correct answer and show why. Each tool page documents its formula, its assumptions and worked examples, and shows when it was last reviewed.

How we build and check tools

• Formulas come from standard textbooks and public references (for example the quadratic formula, the amortization payment formula and the compound-interest formula).
• The calculation engine is covered by automated tests, and each tool is checked against hand-worked examples before release.
• Explanations are written for learners: plain language first, then the formal statement.

How content is produced, including AI assistance

We use AI tools to help research and draft explanations, guides and articles. We do not rely on AI for numbers: every figure in a worked example is generated by running the site's own calculator code, and the calculators are covered by automated tests and a build-time audit before each release. Rates, fees and tax rules that change over time (for example eBay fees, PPF and GST rates, income-tax slabs) are checked against the official source named on the page and carry an “as of” date where it matters. Finance pages show a named reviewer where one has reviewed them; health pages are general information and carry a medical disclaimer. AI-written text is never presented as personal experience.

Updates and corrections

We review tools whenever we change them and at least once a year. If you find an error, email [email protected] with the page URL, the inputs and the result you expected. We investigate promptly, fix confirmed errors and update the page's review date.

Independence and advertising

SolveCalcPro is funded by advertising. Ads are labelled, appear separately from tools and explanations, and never influence results or content. We do not accept payment to change a result or an explanation.

Who is responsible

Content is produced and reviewed by the SolveCalcPro editorial team at Hindustan Prime. We are not a licensed financial or tax adviser; see the disclaimer.
