<prompt> Human: My girlfriend and I are graduating this may. Our predicted combined salary out of school is about 110000. I used this calculator to find that after taxes and 10 to a roth 401K our predicted take home is about 6200 a month. Ive done a lot of research but we have never seen anything close to this amount of money, so I am a bit nervous about if I am planning correctly. My predicted monthly costs are about 5000. This includes rent, paying towards debt, utilities, food, bills, insurance car, health, rentershome, misc, entertainment and travel. Rent and debt being the largest costs. We have about 1300 left over for whatever. For the first year we would like to put this into a general saving account to have a bit liquid savings to fall back on just in case. After we have about three months worth of liquid savings, we would like to start investing this money. After the first year I plan to put the extra money into an SP 500 index fund.Does it look like we have forgotten anything in our costs? Should I save more than what I am planning on before I invest? Should I continue to save a significant amount of liquid cash after we have three months costs saved up? Is an index fund the correct type of investing I should be doing? Things to note: We are not planning on having kids. We are planning on getting a 10-15 year mortgage after about 5-10 years. Thats largely what the index fund will be working towards. There is a lot of rounding and guess work but I dont think my numbers are too far off from reality.edit: added food to the monthly budget  <response>: Time is your best friend when investing. Staring early is a good thing.
