1. Put the utilities on the average payment plan so you have a good idea what the bill will run monthly.
2. Make a list of these averages and the other fixed bills. If something is semi-annual or annual, divide the amount by 6 or 12 for a monthly total.
3. To have a good idea of what your variable expenses run, you can write down all your purchases for 2-3 months for an average of what you spend in each category.
4. Take note of anything clothing, yard tools, little appliances, etc that need to be replaced so you can guestimate your miscellaneous needs budget. Also remember to figure in ice melt, spring plants, trash bags, maintenance on the mower, replacement of yard tools, bug treatment and paint/caulking expenses which are seasonal.
5. When you have your 2-3 months of variable expenses recorded, note any trends you could change to spend less such as taking your lunch to work, doing movie night at home, reserving eating out for special occasionals, eliminating dry clean only clothing, or using pay at the pump and refusing to set foot in the convenience stores. Changing where you shop to the most consistently inexpensive place instead of driving all over town for the bargains also saves money. Shopping with a list on a full stomach helps a lot too.
6. To increase your savings rate, move over a set amount of money from checking to savings at the beginning of the month. Have this automatically done on your direct deposit or by the bank. If your bills were higher than expected because of a suprise car repairs or whatever, move over the money to cover it.
