I agree with what everyone said here. Especially Adrian_Thompson. Dave Ramsey's tips and program are really good for someone who is forehead deep in credit card debt and looking to get out from under it. But I do think he goes over the top at times. He calls for people to be on a rice and beans diet, get rid of any entertainment expenses, yada yada yada. Again, when you are drowning, that is probably a good idea to get yourself afloat. Otherwise, some moderation is called for.
Here's my takeaway from everything I've heard/read.
Communication. Talking about the budget and listening to each other is critical. You don't want to make your partner feel resentful about the budgeting/spending. Work it out together, and talk about it regularly. Even monthly if needed. Think of it a bit like a business. Make sure you are on the same page. It will make everything easier. Don't play a blame game. Once you are married, you are going to be a team. It will not help to say something is caused by one or the other. Just acknowledge that something is not going the way both of you want and try to adjust it.
Take advantage of free money. Even if you can't get to the 15% recommended level for retirement savings, at least get all the matching dollars that are on the table.
Get an emergency fund together. The $1000 pot is a good starting point. Once you have that, pretend that it isn't there. That way you won't use it because you have it. As income increases, try to put some of the increase into the emergency fund just to grow it. Once you can get to the 3-6 months of expenses, then you don't need to try to grow it unless income/expenses increase. Doesn't have to be the highest priority to get to 3-6 months, but you want to end up there.
Pay yourself first! This is for everything. Retirement, vacation, gifts, car savings, house savings, emergency fund, entertainment, whatever. Just figure out what you want/need to do and try to put money aside for it. This will have to be balanced against housing/food/utilities costs. We make it a point to put a certain amount per month into vacation fund, car fund, savings for the kids, emergency fund, etc. We do that right off the top. All of our credit card, housing expenses, utilities, and running costs all come after that. When you are starting out, it might not be much. And it is ok if you can't do it early on because you just don't make enough. But as income improves, try to put the increases into the pay yourself pool. As with the debt snowball stuff, the more you make paying yourself a priority, the quicker you can reach you goals...
Pay off the credit cards every month. This is the opposite of the "Take advantage of the free money" step. You don't want to give someone money for not much in return, if anything. If you have trouble keeping the credit card expenses under control, put the credit card away and
try to do cash. Use the credit card for emergencies. If you can't pay it all off, so be it. Just don't do the minimum payment. That way leads to drowning in debt.
Take advantage of free interest financing deals for big purchases. IF we are buy something like tires, furniture, materials for home improvements, we take advantage of a X month no interest deals. We figure out how much we need to pay per month to get it done before month X. It allows you to make a little more interest on your money, rather than the store/bank.
Pay off other debt as fast as you can. Housing debt is not one to worry about paying off as fast as possible. Unless that is your only debt.
And remember, nothing has to be set in stone. Just try to do your best. Some months you'll do great and have extra to put aside or spend, some months you will have greater expenses and might need to dip into some savings. It's ok. Just try to have a few things that are non-negotiable (like 401k match, rent/mortgage/food/electric/gas/water) and then work out the others as best as you can.
