Mint is a free way to manage your money online. It helps you track your spending and saving with a great user interface. It takes a few minutes to set up, you have to link your accounts to it. But once the set up is complete you can quickly see charts and graphs of when and where you are spending your money.
You can setup budgets for spending in different categories. Then you can set up a variety of notifications, like when you have exceeded your budget in a category. There is also a new goals feature which lets you set financial goals and easily track their progress. I’ve been using the service for about 6 months now and I am very please with the results.
