When reporting a calculation problem

It helps if you include:

• Which calculator you used (link to the page)
• The times or numbers you entered
• The result you got and the result you expected

We can't give individual legal or payroll advice. For questions about your entitlements, contact your employer or your local labour authority (see overtime basics for official links).
