Understanding how interest only loans work can help you make smarter financial decisions – especially in today’s changing interest rate environment.
Many borrowers compare interest only loans with regular interest and principal repayments but aren’t always sure which option fits their situation best.
This guide explains interest only loans in a simple, practical way so you can decide with confidence.
What Are Interest-Only Loans?
With interest only loans, your repayments cover only the interest for a fixed period.
This means you are not paying off any part of the original loan amount during the interest-only phase.
Because repayments are lower, interest only loans feel easier on the monthly budget.
However, your loan balance stays the same until the interest-only period ends.

How Long Does the Interest-Only Period Last?
Most lenders offer 1-5 years of interest-only repayments.
During this time, you enjoy the lowest possible monthly instalments.
Once the period ends, your loan switches to standard interest and principal repayments, which are usually higher.
Why Borrowers Choose Interest-Only Loans?
Interest-only isn’t always bad-it can be helpful in the right circumstances.
Many people use it strategically to manage short-term financial pressure.
Common reasons to choose interest-only include:
- Lower repayments create short-term breathing room
- Ideal during renovations or property upgrades
- Helpful for investors managing multiple loans
- Suitable during major life changes like parental leave
- Flexible option when taking a personal loan alongside a mortgage
Sometimes borrowers choose interest-only simply to stabilise their monthly budget for a year or two.

Expert Insights: When Interest-Only Makes Sense
