Sources & Corrections

1. How our calculators are made

Every calculator on CalculateThis.ai is defined by structured data: the input fields, the formula or calculation engine, and the output cards that explain the result. Pages are assembled from reusable templates, and each page displays the formula and assumptions it uses so you can see what is actually being calculated. Calculations run in your browser using the formula shown on the page.

We do not claim that every word on this site was written by a human. Some explanatory copy begins as a generated draft or is assembled from templates, and it is reviewed and corrected by our team before and after publishing. What matters to us is that the calculation itself is transparent: the formula is shown, the inputs are editable, and errors get fixed when they are reported.

2. What these results are — and are not

Calculator results are estimates based on the assumptions you enter and the formula on the page. They are not quotes, not professional advice, and not guarantees of an outcome. Rates, rules, and costs change, and different providers or jurisdictions can produce very different real-world numbers. Treat any result as a starting point and verify it against a current, authoritative source — or a licensed professional — before acting on it for a purchase, contract, filing, treatment, or investment decision.

3. Where our sources come from

Some calculators cite specific sources: official rates, published benchmarks, documented formulas, or other checkable references. Where a page has real source data, the page shows those sources near the calculator with the source name and link, and we state which parameters came from them.

Where a page does not have per-page source data, we do not invent citations. That page carries the general formula and assumption notes instead, and this policy applies to it. A source is listed only when we can point to the actual document or URL we used.

4. How to report an error

If a formula, result, rate, or explanation looks wrong, tell us and we will fix it. The fastest way is the “Spot an error or need an update?” link at the bottom of the calculator page, which opens an email to [email protected] with the calculator already identified.

• Include the calculator page URL (or calculator ID).
• Describe what looks wrong and, if possible, the numbers you entered and the result you expected.
• If you know the current source (rate, rule, or formula reference), include the link.

5. Review timeframe and how fixes land

We acknowledge correction reports within 2 business days and review them within 5 business days. If the report is confirmed, the fix is applied to the calculator’s source data — the formula, the inputs, or the explanatory copy — the affected page is regenerated, and the corrected version is deployed. The page’s “last updated” line changes when the correction ships, so you can tell the page has been revised. If a report is not confirmed, we reply with an explanation.
