<prompt> Human: Monthly Income, expenses, and potential retirement contributions hereI am really interested in opening up my first retirement fund in the next few weeks and have been rigorously researching my options. I plan on investing in the Vangurd 2055 Retirement fund as my main fund. I am planning on contributing the maximum 5,500 per year but was wondering if that would be too high if a percentage relative to my income. Additionally, I am unsure what I should do with the remaining income I would have at the end of the month. Should that be put in savings, a general investment account, or even a rainy day fund? My income and expenses will remain constant until I graduate in May. All feedback would be greatly appreciated. Thanks!  <response>: You wont regret socking away the maximum allowed sum in a tax-protected retirement fund. Starting at 22 will pay off in spades down the road. Way down the road... 40 years from now.Having said that your firm priorities should be:1. Rainy day cushion fund equal to three to six months living money2. Maximize retirement savings3. Savings for a big near-to-medium-term purchase car, house, etc.4. General investment accounts
