Thanks for the article Jamie. What would be a better frequency of payment for a) Fixed rate loans and b) Variable loans ? Weekly, fortnightly or monthly? (assuming any option is doable) I will be on a fixed rate loan of an IO loan and want to be able to save every penny I can. I am paid weekly and can put that money into the offset account. So interest accounted on a daily basis will bring the payments down. It seems to me that a monthly payment would be the most fruitful way forward in my case. Or did I get it wrong ?
