For a calculation issue, include the calculator name, the values entered, the result shown and the result you expected. Please do not email payment-card numbers, passwords, tax identifiers or other sensitive information.
Response and scope
We aim to review useful reports, but cannot promise a response time or provide individual financial, legal or tax advice. Messages that are abusive, automated or unrelated may not receive a reply.
Before contacting us
Calculator results can differ from a receipt because of line-by-line rounding, location-specific tax treatment, fixed coupons, fees or merchant rules. Check these details first and tell us which applies.
