I love what Mint.com does for consumer households. The website offers many budget services, relevant financial planning advice, and much more. I’m not trying to sell anything for them—I’m unaffiliated. I just like them. And I’m not the only one. Many sites are giving them free adverising (such as I am here) simply because they like Mint so much.
There’s nothing else like it. You really ought to consider it no matter how detailed you are with finances. They can help you be better.
