For many Australians, a mortgage represents the largest financial commitment they will ever have. A common question people ask is whether they should prioritise paying off their mortgage as quickly as possible or begin investing at the same time.
There is no single answer that suits every household. However, understanding the trade-offs between the two approaches can help investors make more informed long-term financial decisions.
Why Many Australians Prioritise Paying Off Their Mortgage
The traditional approach to wealth building in Australia has often been straightforward: buy a home, focus on reducing the mortgage as quickly as possible, and begin investing once debt levels are reduced.
- Financial security
- Lower debt levels
- Peace of mind
- Greater flexibility later in life
For many households, owning a home outright provides psychological comfort, particularly during periods of economic uncertainty.
The Opportunity Cost of Paying Down Your Mortgage
Every dollar directed toward additional mortgage repayments is a dollar that cannot be invested elsewhere. This concept is often referred to as opportunity cost.
If investments generate higher long-term returns than the interest rate on a mortgage, allocating some capital toward investing may improve long-term wealth outcomes.
Historical Long-Term Returns
| Asset Class | Approximate Long-Term Return |
| Mortgage Interest Rates | ~5–6% |
| Australian Shares | ~9–10% |
| Global Shares | ~8–10% |
| Australian Residential Property | ~5–7% |
Over long periods, share markets have historically delivered higher returns than typical mortgage interest rates.
A Simple Long-Term Example
| Strategy | Approach |
| Strategy 1 | Direct surplus cash toward paying down the mortgage |
| Strategy 2 | Invest surplus cash while continuing standard mortgage repayments |
In Strategy 1, the household becomes debt-free sooner. In Strategy 2, the household builds an investment portfolio while gradually reducing the mortgage.
The Psychological Factor
For many Australians, the emotional benefit of owning their home outright can outweigh potential financial benefits of investing earlier.
- Reduced financial stress
- Increased lifestyle flexibility
- Greater certainty in retirement
When Investing While Paying a Mortgage May Make Sense
- Stable and reliable income
- Surplus cash flow after expenses
- A long investment time horizon
- Comfort with investment market volatility
Longer investment horizons can allow investors to ride through short-term market fluctuations and benefit from long-term compounding.
