Top 7 Factors in Home Loan Comparison
When interest rates shift, small differences in loan terms can cost you thousands. A focused comparison — using the right rate, fees and features — shows what a loan really costs over your balance.
Key Takeaways
- Use the comparison rate rather than the headline rate to see the true annual cost once fees are included. Always read the product disclosure statement for charges the comparison rate may omit.
- Check your LVR. Your loan-to-value ratio, loan purpose and credit profile shape every offer you receive. Staying at or below 80% LVR avoids lenders' mortgage insurance and typically delivers lower rates.
- Prioritise features. Offset accounts, redraw and split-loan options affect your cash flow and total interest more than a small headline-rate difference. Weigh each feature against its true cost.
- Score offers consistently. Use a checklist and sample calculations to rank loans by total cost across your intended holding period. This removes emotion and makes refinancing decisions easier.
- Get a tailored review. Run your numbers in a calculator, request personalised quotes and compare worked examples for your exact loan amount and LVR.
The Top 7 Factors to Compare
The single most useful starting point. It combines the headline rate with most common fees into one annualised figure, allowing a fair cost comparison across products.
Fixed, variable or split — each type behaves differently across rate cycles and affects your repayments, flexibility and access to features.
Establishment, package, monthly and discharge fees all add to your real cost. Annualise one-off charges so they're directly comparable across products.
Your loan-to-value ratio determines whether LMI applies. Crossing the 80% threshold can add thousands to your cost and restrict the offers available to you.
Offset accounts, redraw, split options and portability — assess their presence, withdrawal limits and costs. Features can shift total interest paid more than small rate differences.
Fixed-rate break fees, redraw restrictions and other product-specific limits all influence your long-run cost and ability to refinance or switch later.
Owner-occupier versus investor status, your credit score and repayment capacity all affect which rates and products lenders will offer you.
Why a Proper Comparison Saves You Thousands
The advertised rate shows only the interest portion. The comparison rate combines interest with most upfront and ongoing fees into a single annualised figure — making it the better starting point for shortlisting lenders.
Note: Comparison rates may not capture every charge. Always read the product disclosure statement and confirm lender-specific conditions before committing to a product. Rates shown are for illustration only.
Your LVR, loan purpose and borrower profile also shape the offers you receive. Crossing the 80% LVR threshold typically triggers LMI, which can effectively raise your rate by a meaningful amount. Investor loans and interest-only structures commonly cost more and carry fewer borrower-friendly features — factor those differences into every comparison.
Fixed, Variable and Split: How Each Behaves
Understanding how each rate type works across different market conditions helps you choose the structure that fits your cash flow and plans — not just the lowest rate available today.
| Loan Type | Best Suited To | Key Benefit | Main Trade-Off |
|---|---|---|---|
| Fixed Rate Certainty | Borrowers who need predictable repayments — renovations, family budgets, investment plans | Locked repayments for the fixed term, regardless of rate movements | Limited offset/redraw access; significant break fees if you exit early |
| Variable Rate Flexible | Borrowers who value access to features and expect rates to settle or fall | Full offset accounts and redraw access to reduce interest and manage cash flow | Repayments move with the cash rate; less certainty in a rising-rate environment |
| Split Loan Balanced | Borrowers wanting partial certainty without losing key features | Hedges rate risk while retaining offset access on the variable portion | More complex to manage; break fees still apply to the fixed portion |
A common split is 50/50 — half fixed for short-term certainty and half variable to retain offset access and allow extra repayments. When comparing options, include likely break fees, the value of retained offset access, and at least two realistic rate scenarios to see which structure performs over your intended holding period.
Fees and Features That Actually Move the Needle
Four fees borrowers often overlook account for a large portion of the true cost difference between products.
| Fee Type | Typical Range | How to Treat It |
|---|---|---|
| Establishment / Application | $150 – $990 | Annualise over your planned holding period for a fair comparison |
| Ongoing Package / Monthly | $6 – $20 per month | Multiply by 12 and add to annual cost; check if offset is included |
| Discharge / Exit | $150 – $795 | Factor in if you plan to refinance or sell within the loan term |
| Fixed-Rate Break | Varies significantly by lender | Request a break-fee estimate before fixing; include it in any refinance scenario |
Offset vs Redraw — Key Differences
Offset accounts reduce your interest by applying your savings balance against the loan, which can produce significant savings for borrowers who keep surplus funds near the mortgage. Redraw lets you access extra repayments but often comes with withdrawal limits or fees — and some lenders restrict offset to higher-cost packages.
Weigh each feature's actual value against its cost and be realistic about how you will use it. A $400/year package fee is worth paying if your offset consistently holds $40,000+. It is not worth paying for a redraw-only product.
A Practical Scoring Checklist
A weighted scoring system makes ranking offers consistent and removes emotion from the decision. Use the same loan amount, term and assumptions for every quote so products are genuinely comparable.
| Scoring Category | Weight | Relative Importance | What to Measure |
|---|---|---|---|
| Effective Rate | 50 pts | Comparison rate adjusted for your LVR and loan purpose | |
| Fees | 20 pts | Annualised upfront + ongoing fees across your holding period | |
| Features & Flexibility | 15 pts | Offset quality, redraw access, extra repayments, portability | |
| LMI & Loan Structure | 10 pts | LVR impact, fixed/variable split, break-fee exposure | |
| Lender Service | 5 pts | Application speed, service quality, digital tools |
Sample Calculations — $500,000 Loan, Year One
These figures illustrate how the combination of rate, offset and fees changes the real cost. Use your own numbers for an accurate comparison.
Repeat the calculation for years two to five using an expected rate path, then sum the totals and divide by 60 to get a monthly equivalent. Base your final decision on your holding period and cash flow — not just year one.
Next Steps: How to Run Your Comparison
-
1Record your assumptions
Note loan amount, term, planned extra repayments, expected holding period and whether the loan is owner-occupied or investment. Use the same figures for every quote.
-
2Run a calculator with your numbers
Enter headline rate, comparison rate, offset balance and fees. Test two or three LVR scenarios to see how rankings shift.
-
3Ask lenders consistent questions
Request the comparison rate for your exact loan amount and LVR, a full fee schedule, details of offset and redraw access, and sample break-fee scenarios if you are considering a fixed term.
-
4Prepare your documents early
Payslips, ID, a recent bank statement and the contract of sale speed up the quote process so lenders respond accurately and quickly.
-
5Score and rank offers using the checklist
Multiply each category score by its weight and total the points. The highest score reflects the best combination of cost, features and flexibility for your situation.
-
6Book a short loan review
A broker review of your current structure takes 20 minutes and can identify savings or flexibility improvements not visible in a rate comparison alone.
Questions to Ask Every Lender
- What is the comparison rate for my exact loan amount, term and LVR?
- What are all upfront and ongoing fees for this product?
- Is an offset account available, and how does it interact with redraw?
- What are the break fees if I fix for this period and exit early?
- Are there eligibility conditions or product switches that could change my rate later?
