Ask HN: Rate my startup - automated financial planner

We have just released a beta version of an automated financial planning tool: http://www.fiveminuteretirementplan.com/<p>This tool dynamically creates ETF portfolios based on an investor’s risk tolerance and time frame.<p>The site includes a detailed description of the methodology used to create the financial plans along with links to a spreadsheet with the exact calculations. You can see the methodology and download the spreadsheet here: http://www.fiveminuteretirementplan.com/Home/Methodology<p>Our goal is to create a simple tool that allows a user to explore various "what if" scenarios to see how changing contributions, retirement date, etc. will affect their retirement plan.<p>Please reply with any improvements you think could be made to the site or methodology.
