Where our numbers come from

Every rate, threshold and rule in a calculator comes from a primary source: legislation, regulations, or the official guidance of the government body that sets the figure. We cite sources by name and number so they can be found, for example the Canada Labour Code s.235, Ontario's Employment Standards Act, 2000 s.58, New Zealand's Minimum Wage Order 2026 (SL 2026/16), Australia's Fringe Benefits Tax Assessment Act 1986 and UK statutory instrument SI 2026/15.

News articles, comparison sites, other calculators and data aggregators can alert us that a rate has changed. They are never used as the source of a figure, because they often show the previous year's numbers.

Each calculator page lists the exact documents it relies on in its Sources section, with the date each one was last checked.

How every calculator is built

Every calculator goes through the same five steps before it is published, and again whenever a rate or rule it uses changes.

1. Research the ruleRead the primary source in full and record the rate year, every threshold, the rounding method and the exceptions, such as a province with its own rule or a cap that applies above a certain income.
2. Model it independentlyWrite the calculation as a separate Python model, with every rate held as a named value linked to its source, and test it at and around each threshold.
3. Build the live calculationWrite the calculator that runs on our server. It must return the same answer as the model on every test case before it can go live, and it shows a full breakdown, not only a total.
4. Generate tables and examplesProduce reference tables and worked examples from the checked model rather than typing them by hand, because hand-typed rows are where errors creep in.
5. Review before publishingCheck every figure, source link and date on the page, then publish with an Updated date and a Sources list showing when each source was checked.

Who writes and checks the calculators

Calculators and guides are researched, built and checked by My Easy Calculator, an independent website with no ownership links to any bank, lender, insurer, adviser or government body. Before a page is published or updated, every figure and source on it is checked against the official publication.

We do not list individual authors yet. When we do, each person will be named on our About page with their role and relevant experience, and the calculator pages they work on will link to them. We will not use invented names, credentials or reviewer titles.

How content is produced

We use AI writing and coding tools to help draft explanations, organise research and write code. They do not decide any figure. Every rate, threshold, formula, worked example and source on a page is checked by a person against the official publication before it is published, and calculators must match the independent model described above.

We say this openly because how content is made matters when it deals with money and legal rights. If you find something that reads well but is wrong, please tell us so we can fix it.

Estimates and interpolation

Some official sources publish only part of a scale, such as the fee at a few property values, or stop at a ceiling. Where a calculator has to fill a gap, it says so on the page.

The same applies to ranges that are not set by law. Common-law severance in Canada, for example, is shown as an estimated range alongside the statutory minimum, and the page explains the difference.

Updates and corrections

A calculator is re-checked whenever a rate or rule it uses changes. For most tax and pay figures that means at least once a year when the new tax or rate year starts, plus any mid-year change such as a minimum wage increase.

The Updated date on a calculator page changes only when its figures have genuinely been re-checked, together with the check dates in its Sources list. We do not refresh dates to make a page look newer.

Report an error

Email info@myeasycalculator.com or use our contact page with the calculator page, the inputs you used and the official source that shows a different figure. Replies usually take up to 2 business days. We re-check the figure against the official source and fix the calculator, its tables and its examples if they need it.

Where a correction changes a result someone may have relied on, we say what changed on the page rather than correcting it silently.

Guides and blog articles

Articles on our calculator blog follow the same rules: figures come from official sources, each guide states the tax or rate year it applies to, and guides link to the calculator that does the sum. When the rules behind a guide change, we update it or mark the figures that no longer apply.

We do not publish market predictions, investment tips or opinion presented as fact. Guides explain how official rules work and how to apply them.

Advertising

The site is free because it shows ads served by Google AdSense. Every ad is labelled Advertisement and placed away from calculator inputs, buttons and results, so it cannot be mistaken for part of a calculator or clicked by accident.

Advertisers have no say in what we calculate or write, and no ad changes any result. We do not use pop-up or overlay ads that cover a calculator. How Google uses data for ads is explained in our Privacy Policy and Cookie Policy.
