Fortnightly Budget

So I got paid today! Yay! I get paid every two weeks, so this budget is obviously until I get paid again in two weeks. I know most Americans seem to be paid monthly, but in Australia, the majority of people are paid fortnightly (do you guys call is bi-weekly?). Due to the nature of my job and university (they're linked), my rent, utilities and meal fund are all non-negotiable and come straight out of my paycheck. As I can't reduce these even if I wanted to and as I never see the money, I haven't included them here. I also contribute 10% to my superannuation each fortnight which I also haven't included, again, because I don't see it.

So here goes!

Fixed Expenses

Mortgage Payment $180

Car Payment $170

Total $350

Savings

Car Fund

(to cover insurance, rego and maintenance) $70

God-Daughter's Fund

(to give to her on her 18th birthday) $5

Emergency Fund $250

Total Savings $325

Discretionary

Everything

(groceries, eating out, mobile phone etc.) $300

Graduation Bill

(paying it now to get a head start) $50

Total Discretionary $350

How does that look? Any gaps? Anything I'm spending too much on?
