Some great advice here. I'll see if I can add anything.
1. INCOME vs. FIXED COSTS: You need to go through all of your monthly bills and see how much you two make and how much your FIXED costs are. Lets say you make $4000 each, or $8000 a month. Your mortgage costs $2000, car payments are $600, gym is $100, cable is $75, whatever. Write down all of the costs that DO NOT CHANGE month to month.
2. UTILITIES: Then, either take a representative month, or add up the past YEAR and divide by 12. I save ALL of our bills/statements as well as receipts. Figure out what an average month is for all of those (gas, elec, water, garbage, gasoline). Add that to #1. That may be another $1500-2000.
3. BUDGET: The biggest hurdle, at least for us, is food. We don't spend a lot on entertainment, so we allow ourselves a $62 DirecTV bill. We rarely rent videos. With 4 year old twins at home we don't go out much either. BUT, many people do. So, first, food. SET a budget. There have been months where we've spend $1500 on food. Crazy, huh? Didn't seem like it at the time. One special dinner out, one family dinner out, some fast food, and groceries. It's very easy to spend $250 a week on groceries if you don't pay attention. We reduced ours to $600 a month for all groceries and fast food and are not going out at all right now. I mean, we spent $500 on gasoline last month, so we've tightened our budgets.
4. COUPONS: They suck. BUT, it can save a little. The BEST way to do it is to buy stuff ON SALE with a COUPON and with a DISCOUNT CARD. Example: Jewel had General Foods items on sale. 10 for $20. With the discount card, 10 for $10. Add some coupons, it was 10 for $8. We bought 20, and got a variety of cereal, snacks, and breakfast bars that will last for months. For $20.
5. COOKING: Plan meals. I love to cook, but really only have about 10 things that I cook often. One is stir fry. I priced it out, and it costs me $9 to make dinner for 4 using 1 large chicken breast, green onions, 1 red onion, 1 large broccoli crown, handful of peapods, some cilantro, garlic, and teriyaki sauce. With rice. Another dinner I make is just thinly sliced chicken breasts dipped in flour with italian spices, and fresh capers sauteed in olive oil. Add rice-a-roni and a veggie (i like asparagus or brussel sprouts with salt and olive oil, but only on sale) and that's pretty cheap. Buy fresh each week, not too much, and make sure it doesn't go bad.
Best of luck, and PM me if you need any help. We use our CC to get miles, and balance our checkbook every month. Quicken is great, but it's a lot to deal with, IMO. In other words, as a fellow dunce, I don't use it. Bring home EVERY receipt and add it up each month. If you take out cash, understand where it all goes.
Peace,
