We live off 2/3 my husbands income and have 1/3 automatically put into a savings account. Normal monthly expenses come out of the first amount, and things like taxes/tags and insurance for the car, home taxes and insurance, home improvements, etc. are taken from the savings, when they come due. I also fund my IRA account from the savings account. Any bonus money is also put into savings. We try to keep 3-6 months of expenses in savings. Any extra is invested for retirement.
Years ago, I always divided annual (and bi-annual) expenses into 12 months and put that amount into an envelope each month so that I could cover those items when they came due. If we knew we would need new tires that year, we would price them and save for that monthly, until we had enough for the tires. I like the automatic savings account much better.
We try not to get a tax return. Why should the government have the use of our money all year. I'd much rather plan to owe some than to get a whopping refund that drew NO interest.
I also have a Dollar Savings Account. That's where I deposit all my dollar bills all year long (I use cash only for weekly shopping from a budgeted amount). I also budget and pay myself $20 a month to cut my own hair, that adds up to be $240 a year that goes into the Dollar Savings Account. I almost always save about $1,000 a year with this savings method. This money is used for Christmas and emergency non-budget items.
