The Loyalty Tax: Cost of Not Switching Banks

The loyalty tax is the financial penalty you pay for staying with the same bank while better rates exist elsewhere. On a $500,000 home loan, a rate gap of just 0.50% costs you roughly $2,500 per year in extra interest. On $50,000 in a savings account, earning 1.00% less than the best available rate costs you $500 per year. Across all your products, the total can easily exceed $3,000 annually.

How Banks Price Loyalty

Banks operate on a simple premise: existing customers are less likely to leave than new customers are to sign up. This creates a rational (for the bank) pricing strategy:

• New customers get competitive rates to win their business
• Existing customers gradually drift to worse rates through discretionary pricing, rate changes not passed on, or introductory rates expiring

The ACCC's residential mortgage price inquiry confirmed this pattern. On average, existing home loan customers pay 0.30-0.50% more than new customers for equivalent products at the same bank.

The 10-Minute Self-Audit

Here's how to check your own loyalty tax in under 10 minutes:

Step 1: Log into your banking app and note your current interest rates for your home loan, savings account, and any term deposits.

Step 2: Compare against the best rates:

• Home loans: Check our Best Home Loan Rates
• Savings: Check our Best Savings Accounts
• Term deposits: Check our Best Term Deposit Rates

Step 3: Calculate the gap using the tables above.

Step 4: If the gap is more than 0.15% on any product, you're paying a loyalty tax.

How to Negotiate (Before You Switch)

Switching isn't your only option. Banks have retention teams whose entire job is to keep you. Here's a script that works:

"Hi, I've been reviewing my finances and I've noticed my [home loan rate / savings rate] is not competitive. I've received a quote from [competitor] at [rate]. I'd like to know if you can match or beat this rate, otherwise I'll be proceeding with the switch."

Key tips:

• Have a specific competing rate ready (don't be vague)
• Be polite but firm
• Ask to speak to the "retention team" or "loyalty team" if the first person can't help
• If they offer a small discount, ask if they can do better
• Get any counter-offer in writing before closing other applications

This approach works because acquiring a new customer costs the bank far more than retaining an existing one.

When to Just Switch

Negotiation doesn't always work, and sometimes the gap is too large for a match. Switch outright when:

• The rate gap is more than 0.50% and your bank won't match
• Your bank only offers a temporary discount (e.g., 12 months before reverting)
• You want features your bank doesn't offer (offset account, better app)
• The switching costs are low relative to the annual saving

For savings accounts, switching is almost always worth it. There are no exit fees, no contracts, and you can open a new account online in minutes.

For home loans, refinancing costs $300-$1,000 for variable loans. If your annual saving exceeds $1,000, the refinance pays for itself within the first year. See our refinancing guide for the full process.

What This All Means for Your Wallet

Most Australians are paying a loyalty tax of $1,000-$5,000 per year across their banking products without realising it. The fix takes 10 minutes to diagnose and a phone call or a few weeks to resolve. Compare your current rates, call your bank with a competing offer, and switch if they won't move.
