ING Home Loan Calculator: Complete Guide to Mortgage Repayments
Module A: Introduction & Importance of ING Home Loan Calculator
The ING Home Loan Calculator is a sophisticated financial tool designed to help Australian homebuyers and property investors make informed decisions about their mortgage options. This calculator provides precise estimates of monthly repayments, total interest costs, and loan amortization schedules based on ING’s competitive home loan products.
Understanding your potential mortgage repayments is crucial for several reasons:
- Budget Planning: Helps determine how much you can comfortably borrow without over-extending your finances

Module C: Formula & Methodology Behind the Calculator
The ING Home Loan Calculator uses standard financial mathematics combined with ING’s specific loan parameters to compute accurate repayment figures. Here’s the detailed methodology:
1. Principal & Interest Calculations
For principal and interest loans, we use the standard amortization formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]
Where:
M = monthly repayment
P = principal loan amount
i = monthly interest rate (annual rate divided by 12)
n = number of payments (loan term in years × 12)
2. Interest-Only Calculations
For interest-only periods, the calculation simplifies to:
M = P × (i/12)
After the interest-only period ends, the calculator switches to principal & interest
for the remaining term using the adjusted principal balance.
3. ING-Specific Adjustments
- Offset Accounts: The calculator assumes any offset balance reduces the principal for interest calculations (ING offers 100% offset on eligible loans)
- Rate Discounts: Accounts for ING’s Orange Advantage discounts (up to 0.10% p.a. for eligible customers)
- Repayment Flexibility: Allows for additional repayments without penalty on variable rate loans
- Lenders Mortgage Insurance: Automatically factors in LMI for loans over 80% LVR (Loan-to-Value Ratio)
4. Amortization Schedule Generation
The calculator generates a complete amortization schedule showing:
- Monthly breakdown of principal vs. interest components
- Remaining loan balance after each payment
- Total interest paid to date
- Equity accumulation over time
For academic validation of these formulas, refer to the Khan Academy Finance Courses or University of Utah’s Mathematical Finance resources.
Module D: Real-World Examples with ING Home Loans
Let’s examine three realistic scenarios using current ING home loan products (rates as of June 2023):
Example 1: First Home Buyer – $600,000 Loan
- Loan Amount: $600,000
- Interest Rate: 3.49% p.a. (ING Orange Advantage variable rate)
- Loan Term: 30 years
- Repayment Frequency: Monthly
- Loan Type: Principal & Interest
- Offset Account: $20,000 balance
Results:
- Monthly Repayment: $2,639.48 (without offset: $2,665.72)
- Total Interest: $349,012.80 (saving $11,258 with offset)
- Loan Term Reduction: 7 months shorter with offset
- Break-even Point: After 5 years, 38% of payments go to principal
Key Insight: Even a modest $20,000 offset balance saves $11,258 in interest and shortens the loan by 7 months.
Example 2: Property Investor – Interest Only Strategy

Module G: Interactive FAQ – ING Home Loan Calculator
How accurate is the ING Home Loan Calculator compared to ING’s actual approval process?
The calculator provides estimates based on the information you input and standard ING loan parameters. However, there are several factors that might cause differences during the actual approval process:
- Credit Assessment: ING uses comprehensive credit scoring that considers your full financial history, not just the inputs here
- Living Expenses: ING applies the HEM (Household Expenditure Measure) benchmark which may differ from your actual spending
- Income Verification: The calculator assumes stable income, but ING may adjust for variable income (bonuses, commissions)
- Loan Features: Some ING products have specific conditions (e.g., Orange Advantage requirements) not fully captured here
- Rate Loading: If your LVR is above 80%, ING may apply slightly higher rates than shown
For precise figures, we recommend getting a pre-approval from ING after using this calculator for initial planning.
Can I include ING’s offset account benefits in the calculator?
The calculator allows you to model offset account benefits in two ways:
- Direct Input Method:
- Reduce your loan amount by your offset balance
- Example: $500k loan with $50k offset → enter $450k
- This shows the effective interest savings
- Comparison Method:
- Run two scenarios: with and without offset
- Compare the total interest and loan term differences
- Typically saves 0.5-1.5 years on a 30-year loan
Pro Tip: ING’s offset accounts are 100% offset with no monthly fees – more effective than many competitors who charge $5-$10/month for offset facilities.
For exact offset calculations, use ING’s dedicated offset calculator.
How does ING’s rate compare to the RBA cash rate, and how often do they change?
ING’s home loan rates are influenced by but not directly tied to the RBA cash rate. Here’s how the relationship works:
| Factor | ING’s Approach | Typical Impact on Rates |
|---|---|---|
| RBA Cash Rate | Generally passes on changes within 1-2 weeks | 0.25% RBA change → ~0.20-0.25% ING change |
| Funding Costs | Depends on wholesale funding markets | Can cause independent rate movements |
| Competitor Actions | Monitors major banks’ rate changes | Often matches or slightly undercuts |
| Customer Loyalty | Orange Advantage discounts | Up to 0.10% p.a. discount |
| LVR (Loan-to-Value) | Higher LVR = slightly higher rates | +0.10-0.20% for LVR > 80% |
Rate Change Frequency:
- ING typically reviews rates on the 3rd Friday of each month
- Average 2-3 changes per year (vs RBA’s 8-12 cash rate reviews)
- Historically moves within 0-30 days of RBA changes
- Fixed rates change less frequently (quarterly reviews)
Track historical changes on the RBA website and compare with ING’s rate history.
What’s the difference between ING’s comparison rate and the advertised rate?
The advertised rate (e.g., 3.49% p.a.) is the base interest rate, while the comparison rate (e.g., 3.51% p.a.) includes most fees and charges to give a more accurate cost comparison. For ING home loans:
What’s Included in ING’s Comparison Rate:
- Base interest rate
- Standard establishment fees ($0 for most ING loans)
- Ongoing monthly/annual fees ($0 for Orange Advantage customers)
- Valuation fees (typically $300-$600, sometimes waived)
What’s NOT Included:
- Government charges (stamp duty, registration fees)
- Lenders Mortgage Insurance (if LVR > 80%)
- Early repayment fees (ING doesn’t charge these)
- Redraw fees (ING offers free redraw)
- Late payment fees
Why ING’s Comparison Rate is Often Lower Than Competitors:
| Bank | Advertised Rate | Comparison Rate | Difference | Why |
|---|---|---|---|---|
| ING | 3.49% | 3.51% | 0.02% | No ongoing fees, low establishment fees |
| CBA | 3.89% | 3.91% | 0.02% | $395 annual fee included |
| ANZ | 3.94% | 4.00% | 0.06% | $395 annual fee + $250 establishment |
| NAB | 3.88% | 3.90% | 0.02% | $395 annual fee |
Key Takeaway: ING’s comparison rate is typically very close to its advertised rate because of its fee-free structure. Always compare comparison rates when evaluating loans, not just the headline rate.
How does ING’s home loan calculator handle interest rate rises or potential future changes?
The calculator shows results based on the current interest rate you input, but you can model potential rate changes using these methods:
Method 1: Manual Scenario Testing
- Run your base scenario with current rates
- Increase the interest rate by 0.25%, 0.50%, 1.00% in separate calculations
- Compare the monthly repayment differences
- Example: $500k loan at 3.5% → $2,248/month; at 4.5% → $2,533/month (+$285)
Method 2: Stress-Testing Your Budget
- ING stress-tests applications at +3% above the loan rate
- Enter your rate + 3% to see if you could handle worst-case scenarios
- Example: Current 3.5% → test at 6.5% ($3,160/month for $500k)
- Ensure you have a buffer of at least $500-$1,000/month
Method 3: Using the Extra Repayments Feature
- Calculate your repayment at current rates
- Then calculate at higher rates but keep the same repayment amount
- This shows how extra repayments now can buffer future rate rises
- Example: Paying $2,533 now (4.5% rate) at 3.5% rate would save $42,000 interest
Historical Rate Rise Impacts (ING Data):
| Loan Amount | Rate Increase | Monthly Impact | Annual Impact | Time to Adjust Budget |
|---|---|---|---|---|
| $400,000 | 0.25% | +$58 | +$700 | 1-2 pay cycles |
| $500,000 | 0.25% | +$73 | +$875 | 1-2 pay cycles |
| $600,000 | 0.25% | +$87 | +$1,050 | 2-3 pay cycles |
| $500,000 | 0.50% | +$146 | +$1,750 | 2-4 pay cycles |
| $500,000 | 1.00% | +$295 | +$3,540 | 3-6 pay cycles |
Proactive Strategy: Use ING’s extra repayments calculator to build a buffer that can absorb future rate rises without lifestyle impact.
