Bankwest Offset Account Calculator

An offset account is a type of savings account where your interest earnings are used to offset (reduce) the interest you owe on your home loan. This calculator helps you determine how much you can save by using an offset account with Bankwest.

What is an Offset Account?

An offset account is a savings account linked to your home loan. When you deposit money into the offset account, the balance is used to reduce the amount of interest you owe on your home loan. This can help lower your overall interest costs and potentially save you money over time.

Offset accounts are different from regular savings accounts. With a regular savings account, your money earns interest, but it doesn't affect your home loan interest. With an offset account, the money in the account is directly applied to your home loan balance.

Benefits of Offset Accounts

Lower interest costs on your home loan
Potential tax benefits (depending on your situation)
Convenient way to manage your home loan interest
Can help you pay off your home loan faster

How Offset Accounts Work

The basic principle of an offset account is straightforward. When you deposit money into your offset account, the balance is subtracted from the principal amount of your home loan. This reduces the amount of interest you owe each month.

Monthly Interest Calculation:
Monthly Interest = (Principal - Offset Balance) × (Interest Rate / 12)

Key Considerations

Offset accounts typically have lower interest rates than regular savings accounts
You can only offset the principal amount of your home loan, not the interest
If you withdraw money from your offset account, the offset balance decreases
Some offset accounts have minimum balance requirements

Feature	Offset Account	Regular Savings Account

Example Calculation

Let's look at an example to see how an offset account can work. Suppose you have a $300,000 home loan with a 4% interest rate. You decide to open an offset account with Bankwest and deposit $50,000.

Monthly Interest Calculation:
Monthly Interest = ($300,000 - $50,000) × (4% / 12) = $250,000 × 0.003333 = $833.33

Without the offset account, your monthly interest would be $1,000. With the offset account, you're paying $833.33 per month, saving $166.67 each month. Over a year, that's a savings of $2,000.

Frequently Asked Questions

Can I withdraw money from my offset account?: Most offset accounts have restrictions on withdrawals. You typically need to give notice and may be subject to penalties if you withdraw money that would reduce your offset balance.
Are offset accounts tax deductible?: The tax treatment of offset accounts depends on your individual circumstances. In some cases, the interest earned on an offset account may be taxable. It's important to consult with a financial advisor or tax professional.
What happens if I don't maintain the minimum balance?: If you don't maintain the minimum balance required for your offset account, you may lose the offset benefit. Some banks will automatically remove the offset if the balance falls below the minimum.
Can I have multiple offset accounts?: It depends on your bank and the terms of your home loan. Some banks allow multiple offset accounts, while others may only allow one. It's important to check with your bank before opening additional offset accounts.
How do I open an offset account with Bankwest?: To open an offset account with Bankwest, you'll need to contact your bank or visit a Bankwest branch. You'll typically need to provide details about your home loan and the amount you want to deposit into the offset account.
