I agree with what some of the other posters have said. I also use an Excel spreadsheet to track budget and spending. I don't keep it to the penny, but it does give me a good framework.
I also tracked our spending for the first couple months to figure out what we REALLY spent. Instead of writing it all down in a notebook, which is a good idea, I kept all of the receipts and bills in a manilla envelope and then went through them every week or so. If I made a purchase and didn't get a receipt, I would write it down on a scrap of paper and throw that into the envelope. You'll be shocked by how much you are REALLY SPENDING on some things.
As far as your SO, well my DH isn't so much into the entire budgeting thing either, but he lets me control the finances -- mostly because I've proven to be good at it. We each get our own money to spend each month from the budget and have to check with each other before we make any big purchases -- which we also save in advance for so that we don't buy it on credit.
I also agree with ColinsMom about putting money into your 401k. If your company has one (even with no match), it's a great way to save. Tip: Whenever you get a raise, change your 401k contribution so that half of your raise is going directly into your 401k. After a couple years you could be maxing out your 401k. If you don't have a 401k, then you should think about getting either a Traditional IRA (contributions may be deductible on your fed taxes) or a Roth IRA (you don't pay taxes on the profit when you withdraw at 59.5+).
But, since it doesn't sound like you've got any savings put away at all, I would advise that most money you can manage to save should be put away in an EMERGENCY FUND. The best place to put this is the highest interest savings account (no checking) that you can get -- maybe a credit union or ING. This is your EMERGENCY FUND to be used if your car dies, you have unexpected medical costs, etc. It is not to be used for buying Christmas presents, clothes, dining, etc.
My story: About 5.5 years ago, DH and I had just bought our first home and were both making decent money as engineers. Boom! I got laid off. I found a new job in just a couple months but the scare made me take a good look at our finances and realize that at our rate we weren't going to be able to do many of the things we really wanted to do with our lives. I got pretty serious about cutting back our expenses in order to put together a sound emergency savings fund and to pay off our higher interest loans.
Fast forward to last year -- We had done well with our finances and our life planning. DH's income had increased and I was able to stay at home with our son and we were awaiting the birth of our daughter. And Boom! DH's contract was not renewed. We lived off our savings for 6 months while DH tried to start his own business and ultimately ended up taking a position with a new company. The 6 months without income set us back, but we never lost a night of sleep over it. We had enough savings to live off for at least a year!
Fast forward to this year -- We're still saving up to get back to our past levels, but the bills are paid and we're putting quite a bit aside also. So, it does work.
Here are my hints/tips/tricks for quick savings:
Do you have cable t.v. or phone add-ons (like caller id, call waiting, etc.)? Those are two things that I never had when we were first starting to do some serious savings. (Oh, you should have heard our family members complain when they would come to visit and we had no cable -- like they came to watch our t.v. rather than visit us.) Savings: $35/month or $420/year.
I anaylized our receipts and found that some restaurants were $10 more expensive per visit than others -- we cut out the expensive restaurants altogether and cut down our dining out to no more than once per week. Also, at $2 per soda, we stopped drinking soda when we went out to eat and instead ordered ice water with lemon. Savings: $30/month or $360/year.
We tried to cut down on paying for convenience items -- for instance, it costs more to purchase a rotisserie chicken (cooked) at the store than it costs to purchase the same kind of chicken uncooked and bake it in the oven for 2 hours and buying juice costs more in juice boxes than in a big jug which is usually more than buying the juice concentrate and mixing it myself. Likewise, it's cheaper to drink water out of the tap than to buy soda and it's cheaper to buy soda in a 2-liter bottle than in cans. Savings: $50/month or $600/year.
On our vacations, we could afford to stay delux, but even with the AP rate, that's over $200/wk more than a moderate. I'd rather save the $200.
Don't get me wrong -- it is HARD making the sacrifices, but SOOO worth it! When my husband sees someone his age driving a nice car, he'll often say "I wish I could have a car like that!" That's when I remind him that the guy driving the car is only leasing it and that the guy doesn't have money set aside for his retirement or his kids' college.
People still occasionally laugh at us for our frugality, but we have no debt other that our mortgage and a little left on DH's college loans and we're amassing some tidy savings. We'll get the last laugh.
Good Luck to you!
