Offset Mortgage


An offset mortgage is a type of home loan where a borrower’s savings account is linked to their mortgage account. The savings balance is used to offset, or reduce, the outstanding mortgage balance, resulting in lower interest payments on the loan. This arrangement allows borrowers to potentially pay off their mortgage more quickly and save on overall interest costs.


The phonetic pronunciation of “Offset Mortgage” is: OHF – seht Mawr – gij

Key Takeaways


  1. Flexible Payments: Offset mortgages allow you to make overpayments, underpayments, or even take a payment holiday, providing more control over your loan repayment schedule.
  2. Reduced Interest: By linking your savings and current accounts to your mortgage, the funds offset the mortgage balance and reduce the interest accrued on the loan, potentially shortening the repayment term.
  3. Increased Affordability: Offset mortgages can help borrowers pay off their loans faster and save money, offering tax advantages for higher-rate taxpayers and supporting increased affordability.


An Offset Mortgage is an important financial instrument in the business and finance world as it allows borrowers to potentially reduce their mortgage repayment periods and save significantly on interest payments. This type of mortgage works by linking a borrower’s savings account, and sometimes their current account, to their mortgage thereby “offsetting” the mortgage balance with the savings balance. This reduces the effective amount of mortgage on which the interest is calculated and makes repayments more manageable for borrowers. Offset mortgages provide flexibility, tax advantages for some, and the potential for better financial management, thereby making them a significant and beneficial option in the diverse range of mortgage products available in the market.


Offset mortgages serve as an effective financial tool for homeowners looking to reduce their mortgage interest payments while retaining convenient access to their savings. Its primary purpose is to help borrowers expedite the loan repayment process without sacrificing their liquidity. In an offset mortgage, a borrower’s savings and/or current account is linked to their mortgage, allowing any credit balance to be offset against the mortgage balance, thereby reducing the amount of interest payable on the loan. Essentially, borrowers are able to make extra repayments without committing their entire savings or losing the financial safety net they may need in case of emergencies.

This type of mortgage is especially beneficial for individuals with significant savings who wish to maximize their income while effectively managing their mortgage payments. Offset mortgages can not only help borrowers save thousands in interest payments over time, but they can also reduce the term of the mortgage. Additionally, this arrangement offers more flexibility compared to a traditional mortgage, as homeowners can withdraw their savings if necessary without penalty, depending on the terms and conditions of the mortgage. For borrowers who value versatility and financial security, offset mortgages provide a customized and advantageous strategy for managing both their home loans and their savings.


An offset mortgage is a type of home loan where the borrower’s savings account is linked to their mortgage account. The interest earned on the savings account is used to reduce (offset) the interest payable on the mortgage, thereby helping the borrower to pay off their mortgage more quickly and save on interest. Here are three real-world examples of offset mortgage:

1. Example 1 – ABC Bank Offset Mortgage: ABC Bank offers an offset mortgage where a borrower has a mortgage of $200,000 at an interest rate of 3.5% and a savings account with a balance of $25,000. Instead of earning interest on their savings account, the borrower offsets their mortgage interest. As a result, the interest is only calculated on the remaining $175,000 ($200,000 – $25,000). This allows the borrower to save on interest payments, potentially reducing the mortgage term and total interest paid over the life of the loan.

2. Example 2 – DEF Credit Union Offset Mortgage: DEF Credit Union provides an offset mortgage product where a borrower has a mortgage of £300,000 with an interest rate of 2.5%. They also have a savings account with a balance of £50,000. Linking the savings and mortgage accounts means that interest is only charged on £250,000 of the mortgage (£300,000 – £50,000). As a result, the borrower saves on interest, and potentially reduces the mortgage term and overall cost of the loan.

3. Example 3 – GHI Mortgage Company Offset Mortgage: GHI Mortgage Company has an offset mortgage for a self-employed borrower who experiences a variable income throughout the year. The borrower has a mortgage of $350,000 with an interest rate of 4.0% and a savings account with a balance of $60,000. By linking the savings account to their mortgage, the borrower offsets the mortgage interest on the remaining $290,000 ($350,000 – $60,000). This allows the borrower to save on interest payments while also providing a flexible financial tool for managing irregular income.

Frequently Asked Questions(FAQ)

What is an offset mortgage?

An offset mortgage is a type of home loan where a borrower’s savings account is linked to their mortgage. The amount saved is used to offset or reduce the interest calculated on the mortgage.

How does an offset mortgage work?

An offset mortgage works by allowing borrowers to use the balance in their linked savings account to reduce the interest charged on their mortgage. The balance in the savings account is “offset” against the mortgage balance, and the borrower only pays interest on the remaining amount. The more savings you have, the less interest you pay on your mortgage.

Are there benefits to an offset mortgage?

Yes, there are several benefits to having an offset mortgage. These include potentially lower interest payments, faster mortgage repayment, and maintaining access to your savings. Additionally, an offset mortgage may also save you money on taxes, as you will not be earning interest on your savings subject to tax.

Are there any disadvantages to an offset mortgage?

Some potential disadvantages of an offset mortgage can include higher mortgage rates compared to traditional mortgages, limited availability of offset products, and a potential reduction in savings interest if you could have earned a higher interest rate in a different savings account.

Can I access my savings if they are linked to an offset mortgage?

Yes, you can access your savings in an offset mortgage, just like a regular savings account. Keep in mind that withdrawing savings will decrease the amount offset against your mortgage, which may result in higher interest payments.

How can I apply for an offset mortgage?

You can apply for an offset mortgage through banks, building societies, or specialized mortgage lenders. It’s best to research and compare various lenders to find the right mortgage product for your needs. Consulting with a mortgage broker or financial advisor can also provide valuable guidance.

Is an offset mortgage suitable for everyone?

An offset mortgage is not suitable for everyone. It might be an ideal option for individuals with substantial savings or those who plan to receive regular deposits, such as a bonus or rental income, as the higher savings balance will lead to greater interest savings. Additionally, it’s crucial to weigh the potential benefits against the potential disadvantages before deciding if an offset mortgage is right for you.
