      Hi Akash,
      I can do that. And make sure it work on a phone (that one doesn’t). But it is a bit complicated – I didn’t understand some of the questions. Send me an email with all the details about how the results are calculated and I can quote for the work.

    Hello I have changed the payment calculator to 12 to obtain the correct monthly payment, but I am still getting the annual figure?

      Hi Russell,
      Have you set the interest type to ‘amortisation’? Can you give me a link to the calculator page so I can see what data is being processed?
