A common question we hear is: should you use surplus cashflow to reduce debt or invest for the future?
The short answer is that both can be effective ways to build wealth.
The right approach depends on your personal circumstances, financial goals, tax position, and tolerance for risk.

Summary
There is no single answer that suits everyone.
Reducing debt can improve cashflow, lower interest costs, and provide greater certainty.
Investing can help build long-term wealth, offer income and capital growth, and in some cases be implemented in a tax-effective way.
For many people, the decision is not about choosing one strategy forever. It is about finding the right balance between certainty today and potential growth over time.
Should I borrow money to invest?
Paying down debt can strengthen your financial position in several ways.
It can:
For people who value certainty, debt reduction can feel like meaningful progress because the benefit is immediate and measurable.
Investing surplus cashflow may help you build wealth over the long term.
It can:
However, investing also involves uncertainty. Returns are not guaranteed, and values can rise or fall over shorter periods.
In many cases, yes.
As a general rule, high-interest debt should usually be repaid as quickly as possible. This often includes:
Because the cost of this debt is often high and ongoing.
Interest rates on these types of loans are commonly higher than the returns you might reasonably expect from investing after allowing for tax and fees.
Paying off this debt can therefore deliver a reliable financial benefit equal to the interest you no longer need to pay.
Once these debts are repaid, it is also important to avoid building them up again. Otherwise, you may simply replace one high-interest balance with another.
Generally, yes.
Reducing debt is often considered a lower-risk strategy because the benefit is more predictable.
The effective return is:
Investing, by comparison, involves:
Investing may become more attractive when your debt has a relatively low net interest rate and you have a long-term investment horizon.
This is more likely to apply when:
Over longer periods, investing in growth assets such as shares or property may produce stronger long-term returns than simply directing all surplus cashflow to low-interest debt.
There are several reasons for this:
That said, higher potential returns always come with higher risk. A suitable strategy should reflect your goals and capacity to stay invested through market fluctuations.
Yes, very much.
In Australia, the tax treatment of debt can materially affect whether it makes sense to repay debt faster or invest surplus cashflow instead.
Non-deductible debt is debt where the interest is not tax deductible.
Common examples include:
Because interest on these debts is usually paid from after-tax income, the effective cost can be relatively high. This often makes non-deductible debt a stronger candidate for early repayment.
Tax-deductible debt is debt where the interest may generally be claimed as a deduction, depending on how the borrowed funds are used.
Examples may include:
Because the interest may reduce taxable income, the effective after-tax cost of the debt can be lower than the stated interest rate. In some cases, this may make it more reasonable to invest surplus cashflow rather than repay that debt aggressively.
As always, the right approach depends on your broader strategy, objectives, tax position, and risk profile.
A home loan is usually non-deductible debt, which means repayments are made from after-tax income. For that reason, many people prioritise reducing their home loan before increasing investments.
However, if your home loan rate is relatively low, your cashflow is strong, and your long-term goals favour wealth accumulation, a combined approach may be appropriate.
Yes. In many cases, a balanced approach can work well.
The best strategy does not always need to be all or nothing.
A balanced approach might include:
This approach can help you make progress on more than one goal at the same time.
It can offer a practical middle ground.
A balanced strategy may:
For some people, this can be more engaging and therefore easier to maintain than a strategy focused entirely on one side of the equation.
Before deciding whether to reduce debt, invest, or do both, it helps to ask:
Both debt reduction and long-term investing can be sound financial strategies.
The most appropriate balance will depend on factors such as your goals, time horizon, tax position, tolerance for risk, and existing debt structure. A well-considered strategy should reflect your broader financial circumstances rather than a single rule of thumb.
