Email [email protected]. I read everything and usually reply within a few working days.

Worth writing about

• A result that looks wrong. Send the exact inputs you used and the answer you expected. That makes it quick to reproduce and fix.
• A calculator you wish was here. Mortgage overpayments, car loans, savings goals, VAT.
• Something broken on your phone or browser. Say which one.

There is no contact form, because the site has no server to receive one and stores nothing. Email is the whole system.

I cannot give personal financial, tax or legal advice, and I cannot look at your individual loan or portfolio. That needs a qualified professional.
