HECS vs Saving for a House Deposit — Which Should Come First? (Australia 2026)
If you have HECS-HELP debt and are saving for a house deposit, you face a common dilemma: should you direct spare savings toward repaying HECS, or accumulate your deposit as fast as possible?
The Two Competing Strategies
Strategy 1: Pay down HECS first (or simultaneously)
- Reduce HECS balance → reduce compulsory repayment → increase borrowing capacity → buy a more expensive property
- Cost: slower deposit accumulation → potentially longer to reach deposit target or LVR threshold
Strategy 2: Save the deposit, keep HECS
- Accumulate deposit faster → reach home ownership sooner
- Cost: carry HECS repayment obligation → lower borrowing capacity → lower maximum purchase price
What HECS Costs You vs What It Costs to Stay Renting
The comparison isn’t just HECS repayment vs interest — it’s also about time in the market.
If staying out of the property market for one additional year to repay HECS costs:
- 12 months additional rent (say, $25,000)
- Any property price growth during that year
In a rising market, the cost of waiting can exceed the benefit of entering with a lower HECS balance.
Conversely: In a flat or falling market, the cost of waiting is lower, and the case for optimising your financial position (including repaying HECS) is stronger.
The Mathematical Comparison
HECS “cost”: CPI indexation only (no interest). At 3% CPI: a $30,000 balance costs $900/year to carry.
Savings “return”: A high-interest savings account at 4.5–5.5% on $30,000 = $1,350–$1,650/year.
Net outcome of keeping $30,000 in savings (not paying HECS):
- Savings earn: ~$1,500/year
- HECS indexes: ~$900/year
- Net benefit of keeping in savings: ~$600/year
At current savings rates (above CPI), keeping savings to grow your deposit and letting HECS index has a small positive financial benefit — assuming you don’t need the borrowing capacity improvement.
However: this analysis only holds if your borrowing capacity is not the binding constraint. If HECS repayment meaningfully unlocks a higher purchase price, the equation changes.
Worked Example — Two Borrowers, Same Income
Both borrowers: $90,000 income, $30,000 HECS balance, $60,000 current savings
Alex: Repays HECS, then saves for deposit
- Year 1: Uses $30,000 to repay HECS; $30,000 savings remaining
- Years 1–3: Saves aggressively; reaches $90,000 savings in 3 years
- Enters market in Year 3: No HECS, 10% deposit ($90,000), borrowing capacity ~$590,000
- Target property: ~$660,000
Sam: Saves for deposit immediately (keeps HECS)
- Years 1–2: Saves $30,000/year; reaches $120,000 savings in 2 years
- Enters market in Year 2: HECS still $31,000 (after indexation), borrowing capacity ~$530,000
- Deposit: $120,000 (18%), borrowing: $545,000 needed
- Target property: ~$660,000 — but borrowing capacity capped at ~$530,000
- Gap: Sam can afford ~$620,000 max; Alex can afford ~$660,000
Sam enters the market 1 year earlier but at a lower maximum purchase price. Which is better depends on what happens to prices in the interim.
Decision Framework
| Your situation | Likely better approach |
|---|---|
| Small HECS balance (<$15,000) | Repay HECS first — low cost, meaningful borrowing capacity gain |
| Large HECS balance (>$50,000) | Focus on deposit; HECS repayment too costly relative to gain |
| High income ($120,000+) | Consider partial HECS repayment — the repayment obligation is large |
| Moderate income ($70,000–$100,000) | Modelled case-by-case; split approach common |
| Low income (<$65,000) | HECS repayment obligation is small; focus on deposit |
| Rapid savings growth possible | Save for deposit; HECS can wait |
| Rising property market | Prioritise entering market; keep HECS |
| Flat or falling market | More time to optimise; consider HECS repayment |
A Balanced Middle Path
Many buyers adopt a combination approach:
- Make modest voluntary HECS repayments each year (reducing balance and indexation)
- Continue saving the majority of available funds toward deposit
- Reassess once deposit crosses the 10% threshold (and borrowing capacity matters more)
This avoids sacrificing the deposit accumulation entirely while still addressing HECS growth.
Frequently Asked Questions
Is it better to pay HECS or put extra money in offset?
Once you have a home loan: putting money in an offset account reduces mortgage interest (at ~5.75–6.25%) and is completely flexible. HECS indexation is ~2.5–3% currently. An offset generally beats HECS repayment once you have a mortgage — use the offset, let HECS be repaid compulsorily over time.
What if I get a windfall (bonus, inheritance)?
A large lump sum gives you options: pay HECS in full (if balance is manageable) and use the rest as deposit, or go straight to a larger deposit. Model both scenarios for your specific purchase price and income.
Does the First Home Super Saver Scheme (FHSS) help?
FHSS lets you save for a deposit inside super (concessionally taxed at 15%) and withdraw up to $50,000 for a first home deposit. This can be combined with any HECS strategy — it is a separate tool for boosting deposit rather than addressing HECS.
