additional mortgage repayment or credit card

i'm adding an additional $500 a fortnight into my mortgage..
am i better off putting that money into my credit card debt??

any advice would be super

thanks

Definitely - get rid of the credit card debt first ... the interest rate you are paying is probably twice as high as your mortgage - and will take less time to clear. Once you have cleared that debt, you will have even more money available to pour into your mortgage (should you wish to do so).

I made some explanations about the maths involved in my article: How to Save Effectively

thanks sim

Have you considered redrawing some money on your home loan to pay out the credit card debt?
Assuming the fees aren't too high you could end up saving by paying less in interest. Run the numbers first though because paying high interest for a few months on the money may still be cheaper than paying lower interest for years on the mortgage.
