Our Australia mortgage calculator helps you estimate your mortgage payments and total loan costs with enhanced accuracy and regulatory compliance. Follow these steps to get comprehensive results:
Step 1: Enter Basic Loan Information
Property Price
- Enter the total purchase price of the property
- Include any closing costs if you want them factored into your total cost
- Use the actual price you're paying, not the listing price
- Range: $50,000 to $10,000,000+
Deposit
- Enter the amount you'll pay upfront
- Aim for 20% to avoid LMI (Lenders Mortgage Insurance)
- Include any earnest money or deposits
- Auto-calculation: LMI will be automatically calculated if deposit < 20%
- Minimum: 5% for most lenders (higher LMI costs)
Interest Rate (p.a.)
- Use the nominal interest rate from your lender
- Compare rates from multiple lenders for the best deal
- Consider both fixed and variable-rate options
- Range: 1.00% to 15.00%
Comparison Rate (p.a.)
- Enter the comparison rate including most fees and charges
- This helps you compare loans on a level playing field
- Note: Comparison rate based on a $150,000 loan over 25 years. WARNING: This comparison rate applies only to the example given.
Loan Term (Years)
- Choose between 15, 20, 25, or 30 years
- Shorter terms mean higher periodic payments but less total interest
- Longer terms mean lower periodic payments but more total interest
- Most common: 25-30 years for first home buyers
Repayment Frequency
- Weekly: 52 payments per year (most frequent, lowest total interest)
- Fortnightly: 26 payments per year (popular in Australia)
- Monthly: 12 payments per year (traditional)
- More frequent payments can reduce total interest paid
Loan Type
- Principal & Interest: Standard loan where you pay both principal and interest
- Interest Only: Pay only interest for a set period (usually 5-10 years)
- Interest-only loans have lower initial payments but higher long-term costs
Step 2: Add Annual Costs
Annual Council Rates
- Check your local council website for current rates
- Council rates vary by local government area
- Use the assessed value, not the purchase price
- Auto-distribution: Will be divided by your chosen payment frequency
- Typical range: $1,000 - $3,000 annually
Annual Home Insurance
- Get quotes from multiple insurance companies
- Include both building and contents insurance if needed
- Consider the replacement cost, not the market value
- Auto-distribution: Will be divided by your chosen payment frequency
- Typical range: $800 - $2,500 annually
Step 3: Include Australia-Specific Fees
LMI Premium (Lenders Mortgage Insurance)
- Check the box if you want to include LMI
- Required if deposit is less than 20%
- Premium varies by deposit percentage and loan amount
- Auto-calculation: Based on loan-to-value ratio (LVR)
- Note: Actual LMI premiums depend on lender, LVR and loan size—contact your lender for a quote.
State Selection
- Select your state for accurate stamp duty calculation
- Each state has different rates and concessions
- First home buyer concessions available in most states
- States: NSW, VIC, QLD, WA, SA, TAS, NT, ACT
Application Fee
- One-time fee charged by the lender for processing your loan
- Varies between lenders
- Can range from $0 to $600+
- Typical: $200 - $500
Step 4: Optional Extra Payments
Extra Periodic Payment
- Additional amount you plan to pay each period
- Can significantly reduce your loan term and total interest
- Even small amounts can make a big difference over time
- Example: $200 extra fortnightly can save $100,000+ in interest
One-time Extra Payment
- Lump sum payment you plan to make in the first period
- Could be from savings, bonus, or other windfall
- Immediately reduces your principal balance
- Impact: Reduces total interest and loan term
