<prompt> Human: How do you feel about the advice given in this article There doesnt seem to be much discussion around here about debt to income ratios but there does seem to be a lot of discussion today about people with a lot of debt or having debt collectors hounding themSheryl Garrett, the founder of the Garrett Planning Network, says a good rule of thumb is to have a debt-to-income ratio of less than 36. If you exclude the mortgage payments, aim for less than 28, she says.Those of you out there looking to take on more debt should keep an eye on your DTI ratio and evaluate the size of your emergency fund as mentioned in this article. Its not enough to just say you need 6 months in an E-fund, you need to figure out if you can get away with less or if you need more based on your current obligations.The greater your obligations, the more emergency cash you should have squirreled away, planners say. A single mother with a mortgage would want several months if not more than a year of cash to cover expenses, for example. A freshly graduated single person who has no student debt and who is renting an apartment might need only three months worth.  <response>: What caught my eye was the line about discretionary expenses should be two thirds of your total expenses. This seems a bit excessive to me. If youre spending 3000 a month and 2000 should be something that can be cut if theres an emergency, why are you spending so much in the first place? Unless theyre counting savings and contributions to investements, that just seems like spending way more than you need to
