In short
A teacher's borrowing power depends on income after tax, HECS-HELP, living costs, other debts and the lender's test rate: usually your loan rate plus a 3% buffer. A HECS debt matters: on a $92,882 graduate salary it takes about $3,503 a year, roughly $292 a month, out of what a lender counts as available.
How to use the borrowing power calculator
- 1
Enter your salary and your partner's
Pick your state and step, or type your salary. Add a partner's income if you're applying together.
- 2
Add HECS and other debts
Switch on HECS-HELP for each person with a debt, and add credit card limits, car loans and personal loans.
- 3
Enter living expenses and dependants
Use your real monthly spending. Lenders compare it with a benchmark and use whichever is higher.
- 4
Set the interest rate
Enter the rate you expect to pay. The calculator adds a 3% serviceability buffer, as lenders do.
- 5
Read your estimate and repayments
See an estimated borrowing range and what the repayments would be at your actual rate.
How lenders assess a teacher's income
Lenders look at how much income you have left each month after tax, existing debts and living costs, and whether that covers the repayments on a new loan at a higher test rate. Teachers in permanent roles are usually seen as stable borrowers: salaries are set by public agreements, rise on known dates and are paid fortnightly.
- Base salary from your state's pay scale is counted in full for permanent and long-term temporary teachers.
- Allowances and incentives such as rural payments may be counted in part, or only if they're ongoing.
- Casual relief income is often averaged over a period, and some lenders want a track record first.
- HECS-HELP is treated like a debt repayment, because it reduces your take-home pay.
The 3% serviceability buffer
Banks test whether you could still make repayments if rates rose. The standard approach is to assess the loan at your interest rate plus 3 percentage points. If your rate is 6%, the lender checks you could afford repayments at 9%. That's why borrowing power is lower than you might expect from today's repayments alone.

Teacher-specific things to raise with a lender
- Known pay rises. Your next scheduled step and any agreed pay rise. NT teachers have 4.3% due from January 2027, and Tasmanian teachers 3% from March 2027. Some lenders consider these with evidence.
- Back pay coming. If you're owed back pay, such as Victorian teachers under the VGSA 2026 once approved, it's a one-off and is unlikely to be counted as income.
- Part-time work. Lenders use your actual FTE salary. If you plan to drop days after a baby, tell your lender: they're required to consider foreseeable changes.
- Rural and remote housing. If you're in subsidised housing (for example a 100% rental concession in remote NT), lenders treat your living costs differently.
- Professional packages. Some lenders offer discounts or waive lenders mortgage insurance for some professions. Whether teachers qualify varies, so compare offers.
What this estimate is and isn't
The calculator gives a realistic estimate based on the same building blocks lenders use: net income, HELP, debts, expenses and a buffered rate. It isn't a pre-approval. Each lender uses its own expense benchmarks and policies, so results differ between banks. A mortgage broker or lender can tell you what you'd actually be offered.
