Editorial Policy

A calculator is only worth as much as the figures behind it. This page states where those figures come from, how often they are checked, what they deliberately leave out, and what happens when one of them turns out to be wrong.

It is written to be checkable rather than reassuring. Where a claim has an exception, the exception is stated next to it.

Who Is Responsible

Any Help Me is an independent site with no parent company, no investors and no commercial relationship with any bank, lender, insurer, tax agent or health provider. Nobody pays to appear here, and no result any calculator produces is influenced by an advertiser.

It is run and maintained by one small team rather than a newsroom, and it does not employ accountants, tax agents, financial advisers or clinicians. That is the honest limit of what this site is, and it is why the sourcing below matters more here than a byline would: the authority behind a number on this site is the authority that published the number, not the person who typed it in.

Corrections, questions and complaints all go to hello@anyhelp.me, which is read by the people who maintain the site.

Where the Numbers Come From

Tax rates, thresholds, contribution caps and duty scales are taken from the body that sets them, never from another calculator or from a summary article. In practice that means:

• Australia: the Australian Taxation Office for income tax, PAYG and GST; the relevant state revenue office for stamp duty.
• United States: the Internal Revenue Service for federal brackets, the standard deduction and FICA rates and wage bases.
• United Kingdom: HM Revenue and Customs for income tax, National Insurance and Stamp Duty Land Tax.
• New Zealand: Inland Revenue for PAYE and GST.
• South Korea: the National Tax Service for income tax, and the four national insurance schemes for their own contribution rates and ceilings.
• Exchange rates: European Central Bank reference rates, published once per working day, fetched live by the currency converter.

Formulas that are not set by anyone, such as compound interest, loan amortisation or unit conversion, are arithmetic. They are implemented from the standard definition and checked against worked examples rather than sourced.

How Often They Are Checked

Every jurisdiction's figures are reviewed at least once a year, timed to that jurisdiction's own tax year rather than to the calendar. Australia changes in July, the United States and South Korea in January, the United Kingdom in April, and each is checked as its new year begins.

A review means going back to the source listed above and confirming each figure against it, not scanning for news of a change. A rate that has not moved is still re-read, because the failure that matters is not noticing.

What These Tools Are Not

Every calculator here is an estimate built for orientation: comparing two offers, sanity-checking a payslip, working out whether a plan is roughly affordable. None of them is a filing, a quote, a valuation or a diagnosis.

The specific omissions are worth naming, because a number with the wrong scope is more misleading than no number at all:

• Tax and salary tools apply the headline rules. They do not model itemised deductions, tax credits, salary sacrifice, pre-tax contributions, local or city taxes, or the many circumstances that change an individual's liability. Where a rate is approximated rather than applied in full, the calculator says so on its own page.
• Property tools ignore concessions, exemptions and first-buyer schemes unless a tool names them explicitly, and none of them is a lending decision.
• Health tools are general population formulas. They are not clinical assessments, they do not account for individual medical history, and no result from them should change a treatment, a medication or a decision to seek care.

Anything with consequences deserves the relevant authority's own calculator, or a qualified professional who can see your full circumstances. Nothing on this site is financial, legal, tax or medical advice, and it is not offered as a substitute for any of them.

Reporting an Error

If a figure looks wrong, it may well be. Send the tool name, what you entered, what it returned and what you expected to hello@anyhelp.me.

Reports are read and answered. A confirmed error in a rate, threshold or formula is corrected ahead of any other work, and the correction ships to everyone at once, because the whole site is static files with no per-user state. A report that turns out to describe correct behaviour still gets a reply explaining why.

Advertising and Independence

This site carries advertising, and it would be misleading to describe it otherwise. What advertising does not do is decide what gets built or what a calculator returns. No tool exists because an advertiser wanted it, no result is weighted toward a sponsor, and there are no affiliate links to lenders, brokers or insurers anywhere on the site.

The About page describes how ads and analytics are configured, including which external hosts are contacted and when, and the Privacy Policy covers what is and is not collected.

Changes to This Policy

If the sourcing, the review schedule or the limits above change, this page changes with them. It describes how the site is actually run, so it is worth nothing if it drifts from the practice.
