Contact AtoZ Calculators About a Specific Tool

A clear message helps us understand what happened and which part of a calculator needs review. Start by naming the calculator exactly as it appears on the page. Then list the values you entered, including units, dates, percentages or selected options. Add the result shown on screen and explain what you expected to see.For example, a useful Asphalt Calculator report would include the length, width, compacted thickness, density and displayed weight. A Chronological Age Calculator report should include the birth date, comparison date and displayed years, months and days. A finance-calculator report may need the pay period, percentage or deduction option used, but it should never include an employer login, bank number, tax identification number or complete payroll record.If the problem occurs only on a particular device, tell us whether you used a phone, tablet or computer and name the browser. You may also mention the action that caused the issue, such as selecting Calculate, changing a unit or opening the page from a saved link.

Types of Messages We Review

Report a Calculation Problem

Send a report if the displayed result does not match the formula or explanation on the page. Include a reproducible example with every input. We can then repeat the calculation and compare the output with the stated method. A message that only says “the answer is wrong” does not provide enough information for a technical review.

Report Outdated Information

Some calculators and articles refer to tax rules, public programs, rates or official guidance that can change. If you find outdated information, include the page name, the sentence or field concerned and a link to the current official source. We will compare the two sources before changing the page.

Suggest a New Calculator

You can suggest a calculation that is not yet listed in our All Calculators directory. Explain the question the tool should answer, the inputs a user would have and the result it should display. A link to an accepted formula, public standard or official data source is helpful when the subject depends on defined rules.

Report a Website Problem

Contact us if a page does not open, a button does not respond, an image is missing or the layout becomes difficult to use. Include the page address, device type and browser name. If an error message appears, copy its exact wording. This information helps separate a page problem from a browser extension, old cache or temporary connection issue.

Share General Feedback

Feedback about field labels, instructions, result explanations and navigation can help us improve the website. Point to the exact section and describe the change that would make it easier to understand. We may not apply every suggestion, but specific examples are useful during content and interface reviews.

Information to Include in Your Message

• Your name and an email address where you can receive a reply.
• The exact calculator or page name.
• The public page URL.
• All values entered, together with their units or selected options.
• The result displayed by the calculator.
• The result or behaviour you expected.
• The device and browser used if the issue is technical.
• A link to an official source if you are reporting an outdated rule or rate.

Review the message before sending it. Dates, decimal places and measurement units are often important. A complete example can reduce the need for follow-up questions.

Information You Should Not Send

Do not include passwords, verification codes, private account links, bank or card numbers, tax identification numbers, complete payslips, medical records or other sensitive personal information. We do not need these details to review a calculator or website problem.For a paycheck question, use sample or non-identifying numbers where possible. For a health-related or puppy-growth question, describe the calculator behaviour without sending confidential records. If your question requires personal financial, medical, legal or veterinary advice, contact an appropriately qualified professional instead.Messages submitted through the contact form are used to review and respond to the enquiry. Read our Privacy Policy for more information about website data practices.

What Happens After You Contact Us

We first review the message to identify the page and type of request. A calculation report may be tested with the same values. A broken-link report may be checked against the destination page. An outdated-information report may require comparison with a current official source.Genuine enquiries are usually reviewed within two to three business days, although a technical or research-based question may take longer. Sending the same message repeatedly can make the conversation harder to track, so please allow time for review before following up.A reply may ask for a missing input, page address or browser detail. It may also explain that the calculator is producing the expected mathematical result but that the user’s project, payroll system or organisation applies an additional rule outside the tool.

Calculation Results and Professional Advice

AtoZ Calculators provides general calculation tools and explanatory information. Contacting the website does not create a professional-client relationship. We cannot approve a construction design, prepare a tax return, interpret an employment agreement, diagnose a medical condition or provide veterinary treatment.Construction quantities can change because of site measurements, waste, compaction, product specifications and local requirements. Pay estimates can change because of current tax rules and personal deductions. Health, body-shape and puppy-growth results are general estimates. Use the appropriate professional when a decision carries significant financial, safety, health or legal consequences.

Check These Steps Before Reporting a Technical Problem

1. Confirm that every required field contains a valid value.
2. Check the unit shown beside each measurement or rate.
3. Refresh the page and enter the values again.
4. Try the page in a private or incognito browser window.
5. Temporarily disable a browser extension that blocks scripts, if appropriate.
6. Check whether the problem occurs on another browser or device.

If the issue continues, send the details through the form. Do not change security settings or install unfamiliar software simply to test a calculator.

FAQ’S

How soon should I expect a reply?

We aim to review genuine enquiries within two to three business days. Messages that need technical testing or source verification may take longer.

Can you calculate a result for me by email?

The public calculators are available for direct use. We can review a possible fault, but we do not provide personal tax, engineering, health, legal or financial calculations by email.

Can I request a new calculator?

Yes. Describe the intended users, required inputs, desired output and accepted formula or source. Suggestions are reviewed, but submission does not guarantee publication.

Can I report a broken external link?

Yes. Include the AtoZ Calculators page, the link text and the destination that failed to open. If you know an updated official URL, include it for review.

Should I send a screenshot?

A screenshot can help with a layout or error-message problem, but remove personal information before attaching or sharing it. The written message should still include the page URL and steps that produced the issue.

Where should I start if I only need a calculator?

Return to the AtoZ Calculators homepage for popular tools, or open the complete calculator directory to browse by category.

Messages About Sources, Corrections and Reuse

If you are contacting us about a factual statement, identify the exact wording and provide a current source that directly addresses it. Official government pages, published standards and established research sources are more useful than an unsourced summary. We will review the source in context because a newer publication does not always replace a rule used for a different year, location or purpose.For a correction request, explain the practical effect of the proposed change. A field label may need clearer wording even when the formula is correct. A formula may need an update when the underlying rule has changed. Separating those two cases helps us test the appropriate part of the page.Questions about quoting, linking to or reusing website material should identify the page and intended use. A link to a public calculator is generally different from copying its full text, design or code. Send enough information for the request to be reviewed, and wait for written permission when permission is required.

Keep a Copy of Your Calculation Details

If a result matters to your enquiry, keep a simple record before submitting the form. Note the page URL, date, input values, selected options and output. A browser refresh or later content update may make the original state difficult to reproduce.This record should contain only the information needed to explain the calculation. Replace personal or confidential values with safe example numbers whenever the same behaviour can be demonstrated that way. A reproducible example protects your privacy and gives us a practical case to test.

When Another Organisation Controls the Answer

Some questions cannot be settled by the website team. An employer or payroll provider controls the figures on an actual payslip. A building authority interprets local code requirements. A supplier confirms product properties and order quantities. A doctor or veterinarian evaluates an individual health concern.We can explain the published calculator and review a possible website fault. We cannot change a third party’s records, approve a project or require an organisation to accept a result. Contact the organisation responsible for the final decision when its method differs from the general estimate shown here.
