We opened up a 529 plan. With IRAs (which we do have) you can either pay "before tax dollars" and pay taxes later, or you can pay "after tax dollars" and not pay later. With the 529, we pay $50-75/month before taxes into the fund, and if used for education later, we still don't pay taxes! The best part of this for us is this: we linked our 529 plan to our credit card, and the card pays us 2% of everything we spend BACK TO OUR 529, which is in addition to our "on purpose" savings.
To be able to do this, we went back a few months and looked at every dollar we were spending, then tweaked it where we could, and created a workable budget. This included a $200/month "miscellanious" because that seems to be a thing with us...whether it be a brake job on my car, new tires for my husband's car, or a great deal comes up for a table in our empty breakfast room. If we don't spend the 200, we'll happily bank it, as we are saving money. Anyway, we have a working budget and not just what we wish we were able to do (ha) and then we use that 529 Mastercard for EVERYTHING that will allow us to pay with credit! EVERYTHING but the mortgage, car payments, and stuff that gets taken out of the checks automatically (savings/insurance). That way we get 2% of everything back, put into our son's college fund. A lot of people do this with credit cards and collect air miles, but honestly, I think the college education is not only more important and valuable, but my friends have said that cashing in those miles can be a pain. I'll take good old fashioned money over intangible (and possibly expiring) miles anyday of the week. :)
I understand this could get some people into trouble (using the credit card all the time); most people would suggest something like envelopes with cash in it for each expense and when the money is gone, you don't spend more, and a credit card is only good for a real emergency. That is precisely why we studied our past spending habits (3 months back) before making a budget. #1 to know what we do in "real life", #2 to figure out where we could make changes and cut back, and #3 to make this budget workable so we would actually use it. I have a folder which I use as an expense journal to help keep my budget on track. With this folder, I would write Month: October and the monthly budget total. Then I'll write below that "Week 1" and will list what I spend where, and the totals for grocery, household, and misc (since they aren't one time payments like a bill). Then I subtract those totals from the monthly budget of those expenses. Week 2, the same thing. To tell the truth, using the credit card for everything actually HELPS this process because you can see everything you and your husband spend everyday, you're accountable to each other because you can both look at it, and you don't have to worry about missing receipts=unaccounted for money. The folder is helpful for me because it's like a check register/total so that I know where I'm at on my spending. For food, I may spend much more on 1 week when I buy a value pack of meat and then less the next when I buy no meat at all. I don't believe in the weekly budget being "concrete" because different things come up, as long as it all balances out in the end of the month to be my goals. But I know on week 3 that I only have $__ to spend going in. Then we pay the card off, so we're not incurring debt. Does that make sense?
Then there's the every week stuff: sales papers for food come in the mail on Thursdays. Every Thursday I just work it into my normal routine to keep a basic inventory of what I have in my house (fridge, freezer, pantry), and then I go through the sales papers to see who has what on sale to determine which grocery store I'm going to this week (I go to 1 grocery store for meats and special sales, and Walmart 1x/week for the rest of the stuff: milk, etc that I know is cheaper there). I use the sales papers, the inventory already in my home, and my little coupon file to determine the next week's menu and make my shopping list accordingly. It sounds like a lot, but honestly this is about 30-45 minutes a week and it saves me more money in half an hour than I could earn in 2 hours working to have a simple shopping list already made so I don't buy random things and have to go shopping again 2-3 times a week. The "budget folder", if you keep up with it, wouldn't be more than 10 minutes a day even if you went through a Walmart receipt to list household goods separately from food expenses. Hope one of these things can help you out, or give you ideas for your own home.
