“Your mortgage repayments aren’t just about the loan size—they depend on the interest rate, term length, and repayment strategy you choose.”

A $400,000 mortgage is one of the most common loan sizes in Australia. But how much will the repayments actually cost you each month? The answer depends on several factors, including the interest rate, the loan term, and whether you choose principal & interest or interest-only repayments.

At Energise Home Loans, we help Australians understand their repayment options and find the best structure to suit their lifestyle and long-term goals.

Typical Repayments on a $400,000 Mortgage

• 30-Year Loan at 6% Interest (P&I)
  Around $2,400 per month
  
  
• 25-Year Loan at 6% Interest (P&I)
  Around $2,580 per month
  
  
• 20-Year Loan at 6% Interest (P&I)
  Around $2,860 per month
  
  
• 15-Year Loan at 6% Interest (P&I)
  Around $3,380 per month
  
  

(Figures are estimates only—actual repayments will vary by lender and rate.)

Factors That Affect Your Repayments

• Interest Rate – Even a small rate cut can save you hundreds each month.
  
  
• Loan Term – Shorter terms mean higher repayments but less interest overall.
  
  
• Loan Type – Principal & interest vs. interest-only can change your monthly outgoings.
  
  
• Extra Repayments – Paying a little more each month can save years off your mortgage.
