Corrections Policy

1. Our Approach to Corrections

We aim to publish accurate and reliable financial information, but mistakes can happen. When we identify a material error, our approach is to investigate it, correct it and consider whether any related content or calculations are also affected.

Accuracy is particularly important when publishing information about personal finance. A mistake involving a tax rate, allowance, financial rule, calculation or other material fact could affect how someone understands a subject or the result produced by one of our calculators.

Calfiny therefore treats corrections as part of our wider editorial responsibility rather than simply as occasional website maintenance.

Mistakes can happen

We aim to research, review and test our content before it is published, but no editorial or development process can guarantee that errors will never occur.

Information can be misunderstood or applied incorrectly. A source may be interpreted wrongly. Calculation logic can contain an error, or financial rules may change without an existing page being updated immediately.

Acknowledging that possibility is an important part of maintaining reliable financial content.

Our approach is not to defend published information simply because it has already been through our editorial process. If something appears to be wrong, we aim to examine it on its merits.

We focus on material errors

Not every change made to Calfiny is a correction.

We may routinely improve wording, formatting, navigation, design or explanations without the original content having been materially inaccurate.

Our corrections process focuses particularly on errors that could meaningfully affect what you understand, calculate or conclude from our content.

This could include an incorrect financial fact, outdated rate presented as current, calculation error, inaccurate description of a financial rule or another mistake that materially changes the information being provided.

We investigate before correcting

Receiving a report that something is incorrect does not automatically mean that the published information is wrong.

Financial rules can be complex, and apparently conflicting information may relate to different tax years, jurisdictions, definitions or circumstances.

Where a potential material error is identified, we aim to review the relevant evidence before deciding what needs to change. This may involve returning to the original source, checking more current information, reviewing our interpretation or examining the methodology behind a calculation.

The objective is to correct the underlying problem rather than simply changing something because a different figure or interpretation has been suggested.

Calculator errors receive particular attention

An error within a financial calculator can affect every result produced under the relevant circumstances.

If we identify a material problem involving a formula, rate, threshold, assumption, conditional rule or other part of a calculator’s logic, our aim is to investigate the underlying methodology and correct the calculator where necessary.

A calculator affected by a material calculation error may also need to be retested after the correction.

We may additionally review related explanations or other calculators where there is a reasonable possibility that the same issue affects them.

Corrections are part of maintaining Calfiny

Publishing accurate financial information is not a one-time process.

As Calfiny grows, existing content and calculators will sometimes need to be reviewed, updated or corrected. We consider that a normal part of maintaining a financial information website.

Our approach is straightforward: when we identify a material error, we aim to understand what went wrong, correct the affected information or calculation and consider whether the same problem could exist elsewhere on Calfiny.

2. What We Consider a Material Error

We distinguish between routine editorial changes and errors that could meaningfully affect the information you receive. Material errors receive greater attention because they may change what you understand, calculate or conclude.

Calfiny is updated for many different reasons. We may improve an explanation, simplify wording, adjust a page layout, update a link or correct a spelling mistake without the underlying financial information having been wrong.

Our corrections policy is primarily concerned with material errors — mistakes that could meaningfully affect the accuracy or interpretation of our content or calculators.

Errors in financial facts

Incorrect financial information can be material when someone could reasonably rely on it to understand a financial subject.

Examples could include an incorrect tax rate, allowance, contribution limit, interest rate, eligibility requirement or regulatory rule.

Context also matters. A figure may be accurate for one tax year but become misleading if it is presented as applying to another. Similarly, a financial rule that applies in one jurisdiction may be inaccurate if presented as though it applies universally.

Where an error of this kind could materially change the information being provided, we would generally treat it as requiring correction.

Calculation and methodology errors

Errors affecting our calculators can be particularly significant.

A formula may have been implemented incorrectly, a threshold could be applied at the wrong point, a rate might be assigned to the wrong portion of a calculation or the timing of contributions or compounding could be handled incorrectly.

The displayed result may look perfectly reasonable while still being wrong.

Where a problem materially affects calculator results, we consider the underlying calculation or methodology to be the issue that needs correcting rather than simply changing the explanation surrounding it.

Material omissions

An error does not always involve publishing an incorrect statement.

Leaving out important information can also create a misleading impression.

For example, a financial rule may have an important eligibility condition or limitation that materially changes how it applies. If our explanation omits that condition and consequently suggests the rule applies more broadly than it does, the omission may warrant correction.

We consider whether the missing information could reasonably change how the content is understood.

Misleading presentation

Individual statements can sometimes be technically accurate while the overall presentation creates an inaccurate impression.

This may occur if uncertainty is presented as certainty, an estimate is described as a known outcome or important limitations are obscured by the way information is framed.

Where presentation materially changes the meaning of otherwise accurate information, we may treat that as an accuracy issue rather than simply a matter of editorial style.

Outdated information

Financial information changes.

Content becoming outdated is not necessarily evidence that it was incorrect when published. However, information may require correction or updating when it continues to be presented as current after a material rule, rate or threshold has changed.

We consider the nature of the information, the context in which it appears and whether a reasonable reader could be misled about its current relevance.

Routine editorial changes

Many changes do not constitute material corrections.

These can include fixing spelling or grammar, improving readability, changing formatting, updating navigation, replacing a broken link or rewriting an explanation without changing its substantive meaning.

We may make these changes as part of normal editorial maintenance without treating them as formal corrections.

The distinction is based on impact rather than the size of the edit. A one-digit error in a tax rate could be material, while rewriting several paragraphs for clarity might not alter the underlying information at all.

Our general test is therefore: could the error meaningfully change what someone understands, calculates or concludes from the affected content? If it could, we are more likely to treat it as a material error requiring investigation and correction.

3. How We Review Potential Errors

When a potential error is identified, we aim to investigate the underlying information before making a correction. This helps us distinguish genuine mistakes from differences in dates, definitions, jurisdictions or financial circumstances.

A potential error can come to our attention in several ways. It may be identified during an internal review, while updating related content, through testing one of our calculators or following feedback from a reader.

However an issue is identified, our aim is to understand what has happened before deciding what needs to change.

Returning to the underlying evidence

Where a potential error concerns a financial fact, we aim to return to the source used to support that information and check whether it was interpreted and applied correctly.

We may also consider whether more recent or more authoritative information is available.

For time-sensitive information such as tax rates, allowances, thresholds or regulatory rules, this includes checking that the information applies to the relevant period and jurisdiction.

Understanding apparent differences

Two sources displaying different figures do not necessarily mean that one of them is wrong.

Financial information can vary because sources relate to different tax years, countries, definitions, eligibility conditions or calculation methods. Statistics may also be revised or measured differently.

Where information appears to conflict, we aim to understand the reason for the difference rather than automatically replacing our existing information with an alternative figure.

Reviewing the wider context

Sometimes the problem is not an individual fact but the way several pieces of information have been combined or explained.

We may therefore review the surrounding section or page to determine whether the information remains accurate when read in context.

This can help identify situations where an individual statement is technically correct but the overall explanation could create a materially misleading impression.

Reviewing calculator methodology

Where a potential error affects a calculator, we aim to investigate the calculation itself rather than relying solely on whether the final result appears reasonable.

This may involve reviewing the formula, financial rules, assumptions, rates, thresholds, conditional logic, compounding or other elements that contribute to the result.

Where appropriate, we may compare outputs with independently calculated examples or authoritative information to establish whether the calculator is applying its intended methodology correctly.

Assessing the extent of the problem

An error identified in one place may exist elsewhere.

If the same financial fact, calculation rule or methodology is used across several pages or calculators, we may review related content to determine whether it is also affected.

This is particularly important where shared information has been reused across multiple tools or explanations.

Deciding what action is appropriate

Once we understand the issue, we can determine the appropriate response.

A genuine material error may require a correction to the published content, a change to calculator logic, further testing or updates to related pages. In other cases, the information may be correct but benefit from clarification to prevent misunderstanding.

If our review finds that the original information is supported by the appropriate evidence, we are not obliged to change it simply because it has been challenged.

Our objective is to investigate potential errors fairly, establish what the evidence supports and correct the underlying problem when a material mistake is confirmed.

4. How We Make Corrections

When a material error is confirmed, we aim to correct the underlying problem rather than simply changing the wording around it. The action we take depends on the nature and potential impact of the error.

Once we have established that published information is materially incorrect, our priority is to make the affected content accurate.

The appropriate correction will depend on what went wrong. A factual error in a guide may require a relatively straightforward amendment, while a problem with a calculator’s methodology may require changes to the calculation itself followed by further testing.

Correcting written content

Where a material error affects a financial guide or other written content, we aim to correct the inaccurate information and review the surrounding explanation where necessary.

This may involve replacing an incorrect figure, updating a financial rule, clarifying an important condition or rewriting a section where the original presentation could create a misleading impression.

Our objective is to leave the page accurately explaining the subject rather than simply making the smallest possible edit.

Correcting calculators

Where an error affects a Calfiny calculator, correcting the surrounding text is not enough.

We aim to identify and correct the underlying problem within the calculation. Depending on the issue, this could involve a formula, rate, threshold, allowance, assumption, conditional rule, compounding method or another part of the calculator’s logic.

The corrected calculator may then be retested using appropriate examples to confirm that the change has resolved the problem without introducing another error.

Reviewing related content

A confirmed error can sometimes extend beyond a single page.

The same rate, threshold, financial rule or methodology may have been used in several guides or calculators. Where there is a reasonable possibility that this has happened, we aim to consider whether related content also needs reviewing.

This is particularly important where information or calculation logic has been reused across Calfiny.

Material corrections and routine edits

We do not intend to publish a formal correction notice for every change made to the website.

Spelling corrections, formatting changes, improved wording, updated links and other routine editorial amendments may be made without a correction notice where they do not materially change the financial information being presented.

Where an error is more significant, we may provide additional transparency about the correction where we believe this would be useful to readers.

The appropriate approach will depend on the nature of the error, its potential impact and whether someone who previously relied on the information could benefit from knowing that it changed.

Updating dates where appropriate

Correcting or materially updating content may also result in its review or update information being changed.

We aim not to create the impression that an entire page has been substantively reviewed merely because a minor formatting or editorial amendment was made.

Where dates are displayed, they should provide useful context about the currency of the information rather than simply making older content appear newer.

Corrections should address the cause

An effective correction does more than replace the visible error.

Where reasonably practical, we also want to understand why the problem occurred. This can help us determine whether the same issue could affect other content and whether our research, testing or editorial process could be improved.

Our approach is therefore to correct the inaccurate information, address the underlying calculation or methodology where necessary, review related content when appropriate and use significant errors as an opportunity to improve how Calfiny works.

5. Reporting an Error

If you believe something on Calfiny is inaccurate, outdated or not working as intended, we want to know. Reader feedback can help us identify potential problems that may require investigation or correction.

Despite our research, review and testing processes, errors can occasionally be missed. Readers may also notice information that has changed since a page was last reviewed or encounter a calculator result that appears inconsistent with the circumstances they have entered.

If you believe you have identified a problem, you can contact Calfiny and ask us to review it.

What you can report

You can report a potential error involving any part of Calfiny, including our financial guides, calculators and supporting information.

This might include:

• a financial fact that you believe is incorrect or outdated;
• a tax rate, allowance, threshold or other rule that appears inaccurate;
• a calculator result that does not appear to reflect the information entered;
• a possible error in a formula, assumption or calculation method;
• information that appears to apply to the wrong tax year or jurisdiction; or
• an explanation that you believe creates a materially misleading impression.

You can also tell us about broken functionality or other problems that prevent you from using a calculator as intended.

Information that helps us investigate

You do not need to provide a detailed technical explanation to report a potential error.

However, where possible, it is helpful to tell us which page or calculator is affected, what you believe may be incorrect and why you think there is a problem.

If the issue concerns a calculator, providing the inputs you used and the result you received can help us reproduce and investigate the calculation.

If you have an authoritative source that appears to contradict information published on Calfiny, you can also include that when contacting us.

How to contact us

Potential errors can be reported through our Contact page.

Please provide enough information for us to identify the affected content or calculator. You do not need to provide unnecessary personal or financial information when reporting a problem.

In particular, please do not send passwords, account numbers or other sensitive financial information.

Reports are reviewed, not automatically accepted

Receiving an error report does not necessarily mean that the information on Calfiny is incorrect.

Financial rules can vary according to factors such as tax year, jurisdiction, eligibility and individual circumstances. Different sources may also use different definitions or calculation methodologies.

We therefore aim to investigate material reports against appropriate evidence before deciding whether a correction is required.

Where our existing information is supported by the relevant evidence, we may decide that no correction is necessary. In some cases, however, feedback may reveal that an explanation could be clearer even if the underlying information is correct.

Reader feedback can improve more than one page

A useful error report may identify a wider issue.

If the same information, rule or methodology is used elsewhere on Calfiny, we may consider whether related pages or calculators should also be reviewed.

This is particularly important for calculation errors because the same underlying rule could potentially affect multiple results or tools.

We welcome constructive reports of potential inaccuracies. Our aim is not to assume that Calfiny is correct because something has already been published, but to investigate credible concerns, follow the evidence and correct material errors when they are confirmed.

6. Our Corrections Commitment

Accuracy requires a willingness to correct mistakes. When a material error is identified, we aim to investigate it fairly, correct the underlying problem and consider whether anything else on Calfiny may also be affected.

Corrections form part of Calfiny’s wider approach to accuracy and transparency. Research, editorial review and calculator testing are designed to reduce the likelihood of errors before publication, but they cannot guarantee that mistakes will never occur.

What matters is how we respond when a potential problem is identified.

Take material errors seriously

We aim to give particular attention to errors that could meaningfully affect what someone understands, calculates or concludes from Calfiny.

This includes incorrect financial facts, outdated information presented as current, materially misleading explanations and errors affecting calculator methodology or results.

Routine editorial changes may be handled differently because they do not alter the substantive financial information being provided.

Follow the evidence

A correction should be based on appropriate evidence rather than assumption.

When a potential material error is identified, we aim to investigate the relevant facts, sources, rules or calculation methodology before deciding what needs to change.

If the evidence shows that Calfiny is wrong, our objective is to correct the error rather than defend the existing content simply because it has already been published.

Correct the underlying problem

Where a material error is confirmed, we aim to address its cause rather than only its most visible effect.

For written content, this may mean correcting a financial fact and reviewing the surrounding explanation.

For calculators, it may require correcting the underlying formula, rate, threshold, assumption or calculation logic and then retesting the affected functionality.

Where there is reason to believe the same problem may exist elsewhere, we may also review related content or calculators.

Be proportionate about correction notices

Transparency does not require every spelling change, formatting adjustment or minor clarification to receive a formal correction notice.

We distinguish between routine editorial maintenance and corrections that materially alter financial information.

Where a correction is significant enough that additional transparency would be useful to readers, we may provide information about what was changed.

Learn from significant errors

A correction can also identify an opportunity to improve our processes.

Where appropriate, we may consider why an error occurred and whether changes to our research, sourcing, calculator testing, editorial review or maintenance processes could reduce the likelihood of a similar problem occurring again.

The purpose is not to create an unrealistic expectation that mistakes can be eliminated completely, but to learn from them when they reveal something that could reasonably be improved.

Remain open to being corrected

We want Calfiny to earn trust through the way it handles financial information, not by claiming that everything we publish will always be perfect.

Readers are therefore welcome to report potential errors through our Contact page, and credible concerns should be considered on their merits.

Our corrections commitment is straightforward: investigate credible concerns, follow the evidence, correct material mistakes, fix the underlying problem and learn from significant errors where we reasonably can.
