I'm currently doing a couple of e-Learning subjects at uni and for one, I decided to build a simulation tool to be used to help educate people about how margin loans work. It's a bit rough around the edges and isn't fully functional yet (you can only select one investment - the STW ASX200 index tracking ETF), and I'm still writing the documentation and educational material to go with it ... but I was hoping some of you might like to have a play and see what you think. Margin Loan Simulator Please post feedback or questions. By the way - every time you change a setting, it is reflected in the URL of the page, so if you want to post a link to the simulator settings you're looking at in a forum post, we will be able to see pretty much exactly what you see by clicking on that link (with one limitation - if you set the period to one of "this quarter", "this financial year", "last 3 months", "last 6 months", or "last 12 months", these use the most up-to-date data available, and so they change on a daily basis as new data comes in (currently updated around 11pm). PS. I do intend to build a much more complex and complete version of this for Compare Funds at some point - which will include being able to simulate a portfolio of investments along with automatic investment plans and buy/sell triggers ... but that's a long way off yet.
