We read every message. We can’t give financial or tax advice, but we can explain how a calculator works, fix mistakes and take requests for new countries and tools.
General questions
How a calculator works, feedback, country requests, press and privacy requests.
Report an error
A figure, rate or explanation that looks wrong. Tell us the calculator, the inputs and what you expected.
Before you write
- Please don’t send personal financial details. We never need your name, account numbers, payslips or tax documents. A description of the inputs is enough.
- We can’t tell you whether to borrow, save, overpay or invest, or what to put on a tax return. For that, speak to a qualified, regulated adviser.
- For a share link that reproduces a problem, use the calculator’s “Share link” button; it contains only the figures you entered.
We aim to reply within five working days. Many answers are already on the methodology page and in the guides.
