Editorial Policy

This page explains how CalcTypes creates, reviews, tests, and corrects its calculators and supporting content.

Our core commitment:
  • Every calculator is built using standard, widely accepted formulas — not guesswork.
  • Every calculator is tested with worked examples and edge cases before publishing.
  • Advertising and affiliate relationships never influence calculator logic or results.
1) Our Editorial Mission

CalcTypes is committed to creating calculators that are simple, fast, and as accurate as possible. We believe a good calculator should not just produce a number, but help the user understand what that number means and what it doesn’t account for.

2) Who Creates Our Content

CalcTypes is maintained by Mohammad Faisal Khan (see our About Us page). All calculators, formulas, and supporting explanations are reviewed personally before publishing.

3) AI-Assisted Drafting & Human Review

Some supporting content on this site — such as explanatory text, FAQs, or examples accompanying a calculator — may be initially drafted with the help of AI tools. No content is published without human review.

Human oversight: Every page is reviewed by Mohammad Faisal Khan before publishing for accuracy, clarity, and relevance.

See our full AI Content & Editorial Disclosure for more detail on how and where AI assistance is used.

4) Formula & Rule Verification

We follow a consistent process when building a calculator:

  1. Formula selection: We use standard formulas and widely accepted calculation methods appropriate to the category (e.g., standard EMI/amortization formulas, standard BMI-style health formulas, standard Zakat nisab principles).
  2. Rule/rate verification (when applicable): For calculators that rely on rules or rates that change over time (such as income tax slabs), we reference official or authoritative sources where possible and note a “last verified” date on the calculator page.
  3. Transparency: Each calculator includes assumptions and methodology notes where relevant. See our Methodology page for category-specific details.
5) Testing Standards

Before publishing, we test each calculator using:

  • Worked examples — realistic input scenarios with manually verified expected outputs;
  • Edge cases — zero values, minimum/maximum tenures, very large or very small numbers, and boundary conditions;
  • Cross-checks — where practical, comparing results against known reference calculators or published examples.
6) Editorial Independence

Any advertising or affiliate relationships (when enabled) do not affect how we design our calculators, what formulas we use, or what results are shown. Monetization decisions are kept separate from technical and editorial decisions. See our Advertising Policy.

7) Corrections Process

If you find an issue, please contact us with:

  • the calculator name;
  • the inputs used;
  • the result shown;
  • the result you expected (and why).

We review every correction report. Where a genuine error is confirmed, we update the calculator and note the change via the “last updated” date on that page.

8) Ongoing Review & Updates

We periodically review calculators and update them when we verify changes in rules, rates, or methodology (for example, annual income tax slab changes). Category-specific review notes are described in our Methodology page.
