Report a calculator problem

Please include the page URL, the inputs you used, the result shown, and the result you expected. A screenshot is helpful when the issue involves layout, charts, the map, or a mobile device. Do not include payment details, reservation numbers, account credentials, identification, or other sensitive information.

Report outdated information

Send the sentence or number that appears outdated and link to the current primary source when possible. We prioritize broken official links, changed entrance or reservation rules, date-sensitive benchmarks, and claims that could lead a traveler to under-budget.

Suggest a useful tool

Describe the planning question, the inputs a traveler would know, and the result that would help them make a decision. The best additions solve repeated tasks with transparent math rather than hiding assumptions behind a single score.

Response expectations

We review every useful correction, but cannot promise individual travel advice or a response time. Calculator and source corrections may be published without identifying the person who reported them.
