This calculator uses the standard amortization formula to calculate monthly mortgage payments. It takes into account the loan principal, interest rate, loan term, and country-specific costs to provide accurate payment estimates.
Follow these steps to get accurate mortgage calculations:
The calculator uses the standard amortization formula to compute your monthly payment:
The formula calculates your fixed monthly payment that covers both principal and interest over the loan term.
M = P × [r(1+r)^n] / [(1+r)^n - 1]For most countries, the monthly rate is simply the annual rate divided by 12.
Your complete monthly repayment includes several components:
The total amount you pay each month consists of multiple parts that vary by country:
The base payment that pays down your loan and covers interest charges.
Australian home loans may include Lenders Mortgage Insurance and first home buyer benefits.
Australian mortgages offer fixed-rate terms (1-5 years) then refinance. First Home Guarantee Scheme (Oct 2025) allows 2-5% deposits without LMI. Stamp duty varies significantly by state ($18,500-$30,000+ on $500k property). Offset accounts and redraw facilities provide flexible prepayment options.
As of October 2025, eligible first-home buyers can purchase with deposits as low as 2% through government-backed guarantee.
Standard lending requires 5-20% deposit, but First Home Guarantee allows 2-5% for eligible buyers.
Required when deposit is less than 20% (LVR above 80%) - premium can be capitalized into loan.
One-time property transfer tax paid at completion - rates and concessions vary dramatically by state.
Annual property tax for local services - varies by location, typically $1,200-$2,000 annually ($100-$167/month).
Required by lenders before completion - national average $500-$1,200 annually ($42-$100/month) for $500k property.
Australian mortgages typically offer 1-5 year fixed rates, then refinance to better rates or extend term.
Lower LVR (more equity) gets better interest rates - 20% deposit typically gets prime rates.
Term length impacts monthly payment and total interest - 25 years is most common in Australia.
Features that allow you to reduce interest while maintaining access to extra payments.
Investment properties have different lending criteria and costs compared to owner-occupied homes.
State-specific grants available for first-time homebuyers - amounts and eligibility vary by state.
The calculator provides several important metrics to help you make informed decisions:
Understanding the breakdown of your monthly and total costs helps you plan your budget and compare loan options.
Key ratios and schedules that help you understand your mortgage structure and payment progression.
The percentage of the home value you're borrowing. Lower LTV typically means better rates.
A month-by-month breakdown showing how each payment is allocated.
Monthly mortgage payment is calculated using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the principal loan amount, r is the monthly interest rate, and n is the total number of payments. This covers principal and interest only.
