These simple steps help us identify the page, reproduce the issue and respond more efficiently.
- Use one clear subject for each message instead of combining unrelated issues.
- Include the complete 1Dollars page URL, not only the calculator name.
- Copy important values and results into the email body, even when you attach a screenshot.
- Explain what you expected to happen and why the current behavior appears incorrect.
- Link to an official or primary source when your request depends on a law, tax year, government rule, scientific method, standard or program condition.
- For display issues, include your device type, browser, approximate screen size and the steps that reproduce the problem.
- Do not send repeated follow-up messages for the same request unless you have useful new information.
How to report a calculator problem
A calculator can produce an unexpected result because of a formula error, an unhandled input, a unit mismatch, rounding, a time-sensitive rule, a page-script failure or a difference between the tool's stated method and the result a user expected. A complete report helps separate these possibilities.
Calculator report template
Where possible, test the page once after refreshing it and confirm that the units, tax year, jurisdiction, rate basis and optional settings match your scenario. Please do not include bank statements, identity documents, medical records or confidential account information.
Content corrections and update requests
1Dollars publishes both stable calculations and time-sensitive content. A geometry formula may remain unchanged for years, while tax bands, contribution limits, government benefits, insurance rules, examination scales, nutrition information, brand menus or regulated assumptions can change.
For a correction request, identify the sentence, table, default, formula or output that needs review. Explain the issue in your own words and provide the most authoritative available source. Useful references include government departments, regulators, standards organizations, official product documentation, research publications and current program rules.
Every requested change is reviewed before publication. Submission does not guarantee that the page will be changed, and we may preserve the existing content when the source does not support the request, applies to a different jurisdiction or date, or conflicts with the calculator's clearly stated method.
Suggesting a new calculator or feature
Suggestions are welcome across all current 1Dollars categories, not only finance. A strong proposal explains the question users are trying to answer and the calculation method required to answer it.
Describe the use case
- What should the tool calculate?
- Who is likely to use it?
- What decision or task would it support?
- Does a similar tool already exist on 1Dollars?
Describe the calculation
- Required and optional inputs
- Expected outputs, units and steps
- Global, country or jurisdiction scope
- Formula, standard, research or official source
We review genuine suggestions, but a submission does not create a development commitment, publishing deadline, ownership interest or payment obligation.
Technical and accessibility reports
When reporting a website problem, tell us what you were trying to do, what happened, whether the issue repeats and whether it affects one page or several pages. Include the device, operating system, browser and approximate viewport size when known.
Accessibility feedback may cover keyboard operation, focus visibility, form labels, contrast, touch-target size, screen-reader announcements, zoom behavior, table readability, motion, result order or content that is difficult to understand. A screenshot or short screen recording can help, but written reproduction steps are still important.
Security reports: Do not exploit a suspected vulnerability, access information that is not yours, disrupt the website or publish sensitive technical details before contacting us. Send a concise description, affected URL, reproduction steps and potential impact.
Privacy, cookie and data requests
Email contact@1dollars.org with the subject line Privacy Request. Explain the request, the communication or information involved, your location when relevant, and the email address previously used to contact us.
Depending on the request and applicable law, identity verification may be required before information is disclosed, corrected or deleted. Because most calculators do not require an account, we may have limited ability to connect anonymous or automatically collected data with a particular individual.
Review the 1Dollars Privacy Policy for information about voluntarily submitted details, calculator inputs, cookies, analytics, advertising, retention, security and available choices.
Advertising, media and partnership inquiries
Relevant proposals should explain how the opportunity fits the purpose of 1Dollars and provides genuine value to calculator users. Please include:
- Your full name, role and official business email address
- Company or organization name and website
- Type of campaign, partnership, integration, interview or media request
- Target audience, geographical market and proposed placement
- Expected deliverables, timeline, measurement requirements and budget
- Any legal, compliance, licensing or disclosure information relevant to the proposal
Commercial proposals are evaluated for relevance, user value, transparency, accuracy and compliance with current editorial and advertising standards. Payment does not guarantee acceptance, a particular ranking, positive coverage, an endorsement or a change to calculator results.
