Mortgage Payoff Summary
What is an Offset Mortgage?
An offset mortgage is a type of home loan that links a mortgage account with a transaction or savings account. The money you hold in the offset account directly reduces the mortgage principal on which interest is calculated.
For example:
- Mortgage amount: $300,000
- Offset account balance: $20,000
- Effective principal for interest calculation: $280,000
By reducing the principal, you pay less interest, and this can shorten the mortgage term, even if you continue making the same monthly repayments.
Offset mortgages are popular in countries like Australia, the UK, and Canada because they allow homeowners to save on interest without locking money away in fixed accounts.
How to Use the Offsetting Mortgage Calculator
Using this calculator is simple, and it can save you time and give accurate insights.
Step 1: Enter Your Mortgage Amount
Input the total mortgage you owe or plan to borrow. This is the principal amount of your home loan.
Step 2: Enter Your Interest Rate (%)
Fill in the annual interest rate of your mortgage. Use your lender’s current rate or projected rate for accurate results.
Step 3: Enter Mortgage Term (Years)
Specify the total duration of your mortgage. Most home loans are 25–30 years, but this can vary.
Step 4: Enter Your Offset Account Balance
Add the current balance of your offset account. The higher this balance, the greater your potential savings.
Step 5: Click Calculate

Example Calculation
Let’s take an example:
- Mortgage Amount: $300,000
- Interest Rate: 5%
- Mortgage Term: 30 years
- Offset Account: $20,000
Step 1: Calculate the effective principal:300,000−20,000=280,000
Step 2: Calculate monthly payment using the standard mortgage formula:MonthlyPayment=1−(1+r)−nr×P
Where:
- r = monthly interest rate (5% ÷ 12)
- P = effective principal ($280,000)
- n = total number of payments (30 × 12 = 360)
Result:
- Monthly Payment: $1,502.00
- Total Interest Paid: $245,000.00
By using the offset account, the borrower saves thousands in interest over the mortgage term compared to a standard mortgage without an offset.

Tips for Maximizing Offset Mortgage Benefits
- Keep More in Your Offset Account: The higher your offset balance, the lower the interest paid.
- Regular Contributions: Deposit extra funds into your offset account to reduce principal faster.
- Track Interest Savings: Review your monthly statements to see the savings impact over time.
- Combine with Extra Payments: Offset accounts can be used alongside extra repayments to accelerate loan payoff.
- Refinance Wisely: If your current mortgage doesn’t allow offset accounts, consider refinancing to a flexible mortgage.
Offset Account vs. Traditional Savings
Unlike a traditional savings account, money in an offset account doesn’t earn interest. Instead, it directly reduces the mortgage principal, which is often more tax-efficient than earning interest in a savings account.
This makes offset accounts particularly beneficial in countries where mortgage interest is not tax-deductible. The reduction in interest often outweighs savings account returns.
Why Every Homeowner Should Consider an Offset Mortgage
- Long-Term Savings: Even a small offset account balance can save thousands over decades.
- Flexible Access: Unlike term deposits, you can withdraw funds from an offset account when needed.
- Mortgage Reduction: Lower principal results in shorter mortgage terms.
- Peace of Mind: Clear visibility on how your money impacts your mortgage helps in financial planning.
