Thenes 0 Posted April 30, 2009 I apologise if this has been asked somewhere before but I'm trying to set some costs for postage and insured postage. How is the Insurance Base Cost calculated for Postage with Insurance or rather Registered Post? How is the 4.35 calculated? I'm assuming these costs are input without GST, if so - eg. the Additional Insurance Cost is set at 1.15 (for a $1.25 per extra $100 value of an item sent?). I know it's just 0.01 out, but is this to do with rounding? I'm trying to understand the calculations as the price for Registered Post is different from what I'm calculating. Many Thanks :blush: Share this post Link to post Share on other sites
