I've been a user of mint.com for years now to keep track of my money. I linked all my credit cards, banks, investments online accounts so it could pull the latest data live whenever I wanted to know what my money situation was. The problem with mint is they don't have a way to manually enter an account. There are some accounts like my 457b state retirement fund that they don't link up with, so I can't see how that account is growing. They also don't link up with stuff like annuities, or real value house values through zillow.com. So, I could kinda guess what my net worth was, but not really.
But, yesterday I learned of another site called www.adaptu.com which is the same sort of financial budget management site. It is simple and secure to use and it links up with all my accounts successfully (which mint constantly doesn't). I was able to enter the 457b accounts in manually to be considered in my networth, but I'll have to update the values every quarter since its not live linked. It also links your home value live to current market values on zillow. I love it! Now, I know exactly what my net worth is.
