Why Numford

Built so you can check our work.

  • Sourced and dated

    Every rate links to the official page it came from. Each calculator shows the date we last checked it.

  • Every cent itemised

    Each fee gets its own line, with the working behind it. No hidden totals.

  • Private by design

    No accounts. What you type into a calculator stays in your browser.
