Comparison rates were supposed to help borrowers. Instead, they're based on a $150,000 loan and ignore offset accounts entirely. Here's a better way.

The Burger Problem

You know as well as anyone that what's advertised and what you get can be two very different things. Think hamburgers: the picture looks amazing, but what you unwrap looks like something found under a couch cushion.

Banks used to play the same game — advertising rock-bottom rates with fees buried in the fine print. The government introduced comparison rates to fix this. They didn't.

Why Comparison Rates Fall Short

Comparison rates are calculated based on a $150,000 loan paid over 25 years. If your loan is $500,000 or $800,000 (as most are these days), the comparison rate is barely relevant to your situation.

They also don't account for redraw fees, the benefits of an offset account, or waived credit card fees from a package deal. Two loans with identical comparison rates can have vastly different real costs depending on your circumstances.

A Better Way to Compare

Look at the total cost over the life of the loan. Factor in the fees you'll actually pay and exclude the ones you won't.

For example, comparing three $500,000 loans over 30 years:

Basic loan at 6.0%, $1,000 application fee, no ongoing fees: Total cost $580,191
Offset package at 6.1%, $395 annual fee: Total cost $602,641
Standard variable at 6.2%, $10 monthly fee: Total cost $606,044

The basic loan looks cheapest on paper. But if you maintain an average offset balance above $23,000, the offset package actually saves you more. And that's before considering the tax benefits if the property ever becomes an investment.

The Real Question

Don't ask "which loan has the lowest rate?" Ask "which loan will cost me the least over the time I'll have it, given how I'll actually use it?" That's a real comparison.
