my budgeting is rather (erm) complicated.
firstly, i work out how much i need to cover bills, set expenses and weekly cash in wallet. I always leave a buffer by over-estimating. this money always stays in my primary account. if there's money left over at the next pay day, it's added to my savings.
next, i take most of the remainder and dump it in my savings account. i keep this account at a separate bank (with no card access to it), so i can't touch that money unless i go to the trouble of transferring it back and waiting for the transfer to clear. this is my "true" savings account. money in here is being put aside, not to be touched unless it's an emergency, or i'm buying something big (house, car, major holiday etc)
finally, i put a smaller amount of money into a second savings account i hold at the same bank as my primary account. i call this my "ladies nice things" account, but really it's where i put some spare cash so that if i do see something i would like to splurge on that i can afford, i can use this money. i also use this account for setting extra money aside when i'm saving for smaller ticket items (like the new computer i want, or a short, small holiday).
i did some shopping around and both of my savings accounts are high interest and don't have fees associated with transactions, so it's worthwhile having my money in there. my old "ladies nice things" account wasn't high interest and had transaction fees, so i found i wasn't using it.
the ratio of money put into real savings vs ladies nice things savings varies. if there is something particular i want to purchase, i may swing the favour more toward ladies nice things. otherwise, most of it goes to real savings. either way, i have set myself a minimum contribution to each account on a monthly basis, just to ensure i do actually save some money.
finally - even though i have a credit card, i don't use it if i don't have the money in the bank to cover the purchase i'm making. i use my cc instead of EFTPOS as there's no transaction fees on my card. the credit facility (spending more than i can afford) is again an emergencies only buffer.
i'd much rather sacrifice some fun and save money for a bit, letting it earn interest for me until i can afford something, rather than buying it now and paying a much higher rate of interest on the credit card while i pay it off.
