Mortgages that are offset might be an excellent method to cut costs and save money. They have the ability to either assist you in lowering your regular mortgage payments or in shortening the duration of your loan, which would assist you in paying off your mortgage faster.

As there aren’t that many, it’s likely that most people won’t even be aware of their existence, let alone appreciate their potential. Because of this, homeowners might not be taking advantage of some savings opportunities that would be very pleasant.

What Exactly Is an Offset Mortgage?

Mortgages and savings accounts are typically treated as two distinct financial instruments, but an offset mortgage brings them together.

You can avoid paying taxes on the interest you would receive on savings if you add it to your mortgage.

Interest is calculated on the principal balance of the mortgage, less any funds set aside in a savings account.

Maintaining the same monthly payments over the course of the loan’s lifecycle may also help you pay off your mortgage sooner. Alternately, you could merely decide to reduce the payments.

With a traditional mortgage, you can overpay and reduce your debt over time, but with an offset mortgage, your savings account balance does not affect your loan balance.

Instead of having to ask for the money back or refinance, you can just take it out whenever you want.

How Does an Offset Mortgage Work?

You have two options when seeking an offset mortgage.

If a borrower already has a mortgage, he or she should contact their lender to see if an offset is possible. To qualify for a mortgage savings link, borrowers often need a loan with a variable interest rate. If they have a fixed rate loan, they will have to wait until the term is up. After then, they are free to get a new mortgage with a variable interest rate and an offset savings account.

New borrowers have the option of working with their initial lender to establish an offset mortgage.

The offset savings account is compared by financial institutions to a home equity line of credit (HELOC) that is tied to the primary mortgage. Money placed into the account is applied directly to the principal of the mortgage. Daily interest is determined by the bank using the reduced principal balance.

Like a home equity line of credit (HELOC), the funds are available for use whenever necessary. But when you take money out of the account, interest costs go up and there is less money there to pay down the mortgage.

Offset Mortgage: Pros and Cons

At first glance, it may seem like offset mortgages have only positives; nevertheless, you should also think about the potential drawbacks before deciding if they are good for you.


  • The payment might be reduced. Your mortgage payment could be reduced if you have an interest-only mortgage and put some of the proceeds into savings. Paying less in interest on a larger balance in a savings account.
  • The mortgage could be paid off faster. Overpayments are made by borrowers using interest savings to pay off their mortgages earlier than the loan’s scheduled maturity date.
  • Easy and immediate access to funds. Since savings aren’t deducted from the principal, you should still be able to withdraw your money whenever you need it. This allows borrowers to put their savings toward paying down their mortgage balance without having to wait.
  • It’s possible to use any overpayments or skip a payment if necessary. If you have paid more than required on your offset mortgage, your bank may allow you to reborrow the difference. If you have overpaid on your mortgage, you may be able to delay future payments.


  • It’s possible that interest rates could increase. The interest rate you pay on your offset mortgage is subject to change.
  • It’s possible to pay an annual, monthly, or one-time price. The use of an offset account may cost you money on a regular basis. The upfront costs associated with an all-in-one or money-merge mortgage can be difficult to rationalize.
  • Borrowers can get this type of pricing only with loans that have an interest rate that can fluctuate. Offset mortgage products require you to wait until the end of your term before converting from a fixed-rate to a variable-rate loan.
  • Lack of available U.S. lending options. In the United Kingdom, Australia, and New Zealand, the offset mortgage is extremely popular, while in the United States, it is rather uncommon. The equivalent products offered by American lenders are known as “all-in-one” mortgages or money merge accounts. In essence, these are first-position HELOCs instead of savings-account-linked mortgages.

Should You Get an Offset Mortgage?

You should carefully consider your financial situation before applying for an offset mortgage. A conventional mortgage repayment plan may be more suitable if you are a basic taxpayer with only a consistent income and few savings.

On the other hand, an offset mortgage could be beneficial if you are a greater rate taxpayer and/or have large resources (over and above your deposit) that you don’t require immediate access to but could need in the future.

One of the best things about getting an offset mortgage is that you can access your offset funds whenever you like, without penalty or the requirement for a new loan.

Although you have the option to withdraw funds from your savings, doing so would reduce the positive effects of having an offset mortgage in the first place, so you’ll need to exercise some financial restraint. This is due to the fact that the greatest offset mortgage rates are almost always a fraction of a percentage point higher than conventional mortgage rates.

Therefore, you might consider saving for a larger down payment and continuing with a conventional mortgage having a lower loan-to-value ratio (LTV). The rule of thumb is that the LTV gets better as the interest rate gets down.

Tax implications for savings income must also be thought about. Higher-rate individuals can enjoy tax-free interest on the first $500 they earn from savings thanks to the Personal Savings Allowance (PSA). However, the offset choice may be even more advantageous if you are an extra rate taxpayer (i. e., if your taxable income is over $150,000).

Alternatives to Offset Mortgages

Mortgage products that permit overpayments of more than the customary 10% per month could be used instead of setting money aside for debt cancellation.

As we’ve discussed, having more leeway in your mortgage repayment terms may result in a higher interest rate than the lowest mortgage plans, but it may also help you pay off your loan sooner.

You should keep in mind that if you overpay on a conventional mortgage, you will never see those dollars again. It’s also important to check with your mortgage servicer to see if an overpayment is an option. If you don’t, you can have to pay substantial fees for paying off your loan early.

Bottom Line

If you believe an offset mortgage will benefit you, it is important to shop around for the most favorable offset mortgage rate.

It’s possible to get better rates on an offset mortgage by working with an independent broker, who can also assist with more complex and uncommon products, such a buy-to-let mortgage.

When it comes to choosing an offset mortgage, not everyone is created equal. Even if you’re sure an offset mortgage is the best option for you, it’s smart to check out the competition.

In addition to this, you will need to evaluate the savings rates you might obtain out of an offset mortgage in relation to the interest rates you would obtain if you were to simply deposit your money in a bank.


But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful.
