Interest-Only Mortgage Calculator for Australia

Our free calculator helps you estimate monthly repayments when you’re only paying the interest on your mortgage. This is ideal for property investors, people managing cash flow, or anyone looking to reduce early loan payments while planning for the future.

Understand Your Interest-Only Payments Easily

How can our interest-only mortgage calculator help you?

Interest-only loans let you pay just the interest for a set period, keeping your monthly repayments lower at the start. The actual loan principal doesn’t reduce during this time, which can be useful if you’re investing or want extra cash flow.

By entering your loan amount, interest rate, and interest-only term, our calculator gives you an instant estimate of monthly payments. You can see how much you’ll pay each month, plan your budget, and understand how repayments will increase once you start paying off the principal. This makes it easier to decide if an interest-only loan fits your financial strategy and helps avoid surprises later in the loan term.

Things you should know

Frequently Asked Questions

Everything you need to know about using our Interest Only Mortgage calculator.

An interest-only mortgage is a type of home loan where you pay only the interest for a fixed period, usually 1–5 years. This keeps monthly repayments lower early on, which can help with cash flow, especially for property investors or those managing other expenses. However, the principal loan amount doesn’t reduce during this period, so planning for higher repayments later is essential.
With an interest-only loan, your monthly payments cover just the interest charged by the lender. The principal remains the same until you start making principal-and-interest repayments. After the interest-only period ends, repayments typically increase to pay off both principal and interest over the remaining term. These loans are often used by investors or borrowers wanting short-term financial flexibility.
Interest-only loans suit property investors or borrowers who want lower initial repayments to manage cash flow. They can also help those expecting future income growth or planning to sell or refinance before the principal repayment starts. However, they may not suit first-home buyers who need to reduce their loan balance from the start.
An interest-only mortgage calculator gives an instant estimate of monthly repayments during the interest-only period. By entering your loan amount, interest rate, and term, you can see how much you’ll pay each month, plan your budget, and understand how repayments will increase when principal payments begin. It’s a simple way to manage expectations and avoid surprises later.
Potentially, yes. Since you’re not reducing the principal during the interest-only period, the total interest paid over the life of the loan may be higher compared to a principal-and-interest loan. Careful planning and understanding your repayment schedule can help manage costs effectively.
Yes. After the interest-only period ends, you’ll start repaying both principal and interest. Most lenders allow this, but your monthly repayments will increase. Using a calculator beforehand can help you estimate the future repayment amount and plan your finances accordingly.
