Here is out I cut $25,000 in debt down to $12,500 in a year.
Stop dining out. This includes fast food & junk at work. $3 for coffee adds up. I feel crazy guilty for having $4 worth of soda and snacks today. That was almost 1/2 my junk at work budget for the week. You have to take cash out for this stuff and once it's gone, it's GONE.
Stop dining out. Over the weekend, FI and I had two awesome 1lb ribeye steaks (these things were an inch thick and almost no fat!), mashed potatoes, rice pilaf and a bottle of $15 wine. The whole meal came to $35. For TWO 1lb ribeye steaks! Cooked exactly how we like them! And an entire bottle of wine! That is $17.50 per person. The same meal at a mid-range restaurant would have cost double, possible triple if you factor in the wine.
Does anyone really need to have 327 cable channels? No. Cancel them. Get a cheap Netflix account. Or better yet, make a game out of watching every dvd you already own.
Carpool or walk. I carpool with my roommate twice a week now. Saves me probably $50 a month. And if I can walk to a location, I do. Saves me in 3 ways: I'm less apt to buy more than I need since I have to carry it back. I save $$ on gas for stop & go around town trips. I'm healthier and in theory less likely to get sick and need to buy more medicals.
Read all the books you already have. Don't buy new ones. Go to the library. You can get cds and dvds to listen/watch there as well.
Really, really think about what you are buying. Do you REALLY want it? How long before you get sick of it? How needed is it? Do not impulse buy. If you want it bad enough, go back in a day or two for it. This makes a huge difference. In the age of the interwebs, almost nothing can't be found again.
Do you really need to buy gifts for every single person you know on their bday/anniversary/etc? I used to. Then one day I just said "ENOUGH!". 36 year olds do not need a birthday party every year. I will send a card and my good wishes and that's it. No more $25- $40 several times a month for assorted things that come up. I noticed after I implemented this that most of my friends followed suit and no longer do we need to go out and have a gala every time someone's b-day comes up. Instead, we get together and have a pizza or something at someone's house. I will buy gifts for 1. My toddler nieces 2. My fiance and 3. My mother. That's it.
Home maintainence : make sure your windows are sealed and engery efficient. Make sure your faucets don't leak. Don't wash laundry unless you have a full load. In fact, you probably don't need to wash every item after one use. I have jeans I wear 5-6 times before they get a real wash. Until then, they get hand spot washed. Keeps them in better shape too. They last longer. Be aware of your heat, eletric and water usage.
Unless you are a 17 year old high school girl, chances are very high that your peers could care less about what kind of fashion you wear. So shop your closet. My goal for 2010 was to buy NO new clothes or shoes at all. (except socks and underwear as needed) So far, so good. Try to go without new cosmetics (or just don't use them), no mani/pedi, no trips to the salon except for trims. Fashion is expensive and really not necessary. I found that even when I bought new clothes, I'd fall back on wearing the same ones I wore before I bought the new ones anyway.
Switch from name to store brands. This goes for everything from instant rice to laundry detergent. You probably won't know the difference. My roommate swore he could tell the difference between his $11 Tide and my $3 Purex. Well, he assured me he had no allergies so one day, without him knowing, I swapped the contents. He told me he liked the new scent Tide was using. When I finally told him, he never bought Tide again.
Lower your interest rates. I got an interest rate cut from 22% to 10.99% by doing a balance transfer. This means that instead of 5 years to pay my debt, it will take 2.
In addition to saving money, you can also earn more money every month by selling your old junk. I make approx $400 a month selling stuff on Ebay and/or selling dvds/cds at local used cd/dvd stores. I've made $1236 so far in 2010. I have another round of auctions (11 of them) going now that have 5 days to go. They are already up to $42. This means that this week I will get at least $42 for 11 random items that were gathering dust in my room. And this is just from junk that is in my room, apartment etc. I haven't even looked in my scary, dark basement storage area yet. I hear tell that there are large plastic bins full of cds and old collectibles in there.
