Comparison Rate Calculator

Comparison Rate Calculator See the True Cost of Your Loan

This comparison rate calculator works out the true comparison rate on a home loan once fees and any introductory rate period are factored in. Enter your loan amount, term, intro interest rate and term, the standard or revert rate, and your upfront, ongoing, and end fees, and it returns your comparison rate, intro and revert monthly repayments, total interest payable, total fees, and total payments.

Many loans start with an introductory or honeymoon rate for a set period before reverting to a standard rate. The advertised intro rate looks appealing, but it only tells part of the story once fees and the revert rate are added in. Output is an estimate based on your inputs, not a loan offer.

How the Comparison Rate Is Calculated

The comparison rate is a legally required figure in Australia designed to show the true cost of a loan as a single percentage, folding in most fees alongside the interest charged. It’s meant to let borrowers compare loans on a like-for-like basis rather than relying on the headline rate alone.

For a loan with an intro period, the comparison rate blends the intro rate, the revert rate, and the fees charged across the full term. Upfront fees are paid once at settlement, ongoing fees recur monthly or annually, and end fees apply when the loan is discharged. A loan with a low intro rate but high fees can carry a comparison rate close to, or even above, a loan with a slightly higher intro rate and low fees. This calculator does that blending for your specific numbers rather than relying on the lender’s published comparison rate, which is based on a standard loan amount that may not match yours.

How to Use the Calculator

You’ll need the loan details from a product disclosure statement or a lender’s quote:

• Loan amount and loan term

• Intro interest rate and intro term, in months

• Standard or revert rate, what the loan reverts to once the intro period ends

• Upfront fees, charged once at settlement

• Ongoing fees, monthly or annual

• End fees, charged at discharge

The comparison rate calculator returns your comparison rate, your monthly repayment during the intro period, your monthly repayment after it reverts, total interest payable across the loan, total fees payable, and total payments over the full term. Running it with your actual loan details gives a more accurate figure than the lender’s standard comparison rate.

How ADA Financial Services Helps

A comparison rate calculator gives you a single figure to compare against other loans. A broker tells you whether that figure holds up once your actual loan amount and circumstances are factored in, and whether a lower intro rate is worth the fees attached to it.

ADA Financial Services compares intro rate and standard loan products across our lender panel and models the comparison rate against your real numbers rather than the standard $150,000 benchmark most lenders publish. We assess fees, features, and what happens once the intro period ends, so the loan you choose still makes sense after the rate reverts. Our fee is paid by the lender at settlement in most standard cases, disclosed in writing before any application proceeds. We’re based on the Sunshine Coast and work with borrowers across Northern Australia.
