Editorial policy: how we check our figures

Last updated: November 4, 2026

This page explains who makes MyCalcKit, where our figures come from, how calculators are checked, how pages are kept current, and how to report a mistake.

Who writes MyCalcKit

MyCalcKit is researched, written and built by Arpit Chauhan, an independent publisher based in India. The byline "MyCalcKit Editorial Team" on our pages refers to this editorial process, not to a large newsroom. MyCalcKit is not a bank, a tax firm or a financial adviser, and it is not paid by any of them. More on the about page.

Where our figures come from

  • Official sources first: tax brackets, allowances, contribution limits and rates come from the body that sets them, such as the IRS, HMRC and GOV.UK, the Canada Revenue Agency, the Australian Taxation Office, Ireland's Revenue, India's Income Tax Department, central banks and national statistics offices.
  • Health formulas come from health authorities and published research, such as the CDC, NIH and the original papers behind each formula.
  • Not from other calculator sites: we do not copy figures from other calculators or blogs.
  • Every page lists its sources, so you can check each figure yourself.

How we check calculators

  • Before a calculator is published or updated, the figures it uses are checked against the current official source.
  • Worked examples on a page are recalculated separately and must match what the calculator shows.
  • Automated checks run on updates: broken links, structured data, and that no result shows an error or a blank value on desktop or mobile.

How we keep pages current

  • Tax and rate figures are re-checked when governments publish new figures, such as a new tax year or budget, and when we are told about a change.
  • Every calculator and guide shows a "Last updated" date. The date changes only when the content has actually been re-checked or changed. We do not refresh dates for appearance.

Corrections

If you find a mistake, email hello@mycalckit.com or use the contact page with the page address and an official source. We review reports and fix confirmed errors on the page.

Advertising and independence

MyCalcKit is free and funded by Google AdSense ads. Ads appear in marked slots and never inside calculator results. Advertisers have no say in our formulas, figures or what we write, and we do not accept payment for placements or recommendations.

Not professional advice

Our calculators give estimates for general information. For decisions about your own money, taxes or health, check the official source and speak to a qualified professional. See our disclaimer.
