Tertiary Study Budget Calculator

This calculator builds a weekly budget for a tertiary student in New Zealand, showing whether your money coming in each week covers your money going out, and by how much. Studying full-time usually means juggling a student allowance or the living cost component of a student loan, casual or part-time work, and sometimes help from family or savings, against the reality of rent and power, food, transport and everything else from phone bills to course materials. You enter your expected weekly income from each source and your weekly costs under the same headings, and the calculator adds both sides to show your total income, total expenses, and the weekly surplus or shortfall between them. A surplus means you have room to build a small buffer or borrow less through the loan; a shortfall is an early warning to trim spending, pick up extra hours, or reconsider how much you draw down before debt piles up. Because the loan living cost has to be repaid later with interest once you are earning, borrowing only what you need is worth weighing up here rather than after the fact. Adjust any figure and the totals update instantly, so you can test different flatting, work or spending scenarios before committing to them. It is an estimate to guide your planning, not a substitute for your actual bank statements and loan documentation.

Borrowing the loan living cost means a bigger loan to repay later, so borrowing less where you can helps. A shortfall is a sign to trim spending or find more income before you fall behind. Estimate only, to support your budget.

How it works

The calculator adds your weekly income from an allowance or loan living costs, part-time work and any other sources, then your weekly expenses for rent, food, transport and other. The difference is your weekly surplus or shortfall. A surplus can build a buffer or reduce borrowing; a shortfall flags that you need to trim spending or lift income before debt builds up.

Worked example

Income of $300 living costs plus $150 of work is $450 a week. Expenses of $220 rent and power, $100 food, $30 transport and $80 other are $430. That leaves a $20 weekly surplus, a tight but balanced budget where any unexpected cost would need managing.
