You've Got $10,000. What Should You Actually Do With It?

Offset the mortgage, keep it in savings, invest it, add it to super or do something else entirely? Here is how to think about it.

Key Takeaways

There's a big difference between having $10,000 and having $10,000 genuinely spare. Expensive debt and having some emergency savings should come first.
If you have a home loan with an offset facility, $10,000 sitting there at a hypothetical 6% mortgage rate could save roughly $600 in interest over a full year.
If you'll need the money in the next few years, keeping it accessible may matter more than chasing a higher return.
If you won't need it for a long time, investing becomes much more worth considering, but higher potential returns come with the risk of losing money.
Super can be tax-effective, but you're generally locking the money away. First-home buyers may have another option through the First Home Super Saver Scheme.
Don't overlook your own earning power. A qualification or skill that genuinely increases what you earn could be worth more than squeezing another 1% out of your savings.
You don't have to choose just one. Your $10,000 can have several jobs.

You've Done the Hard Part

There is $10,000 sitting in your account that you don't immediately need.

Now everyone has an opinion about what you should do with it.

Your parents say put it on the mortgage. Your mate says buy ETFs. Someone online says put it into super. Your savings account is paying interest, so leaving it there doesn't seem terrible either.

If you haven't worked out how much mortgage you can actually afford yet, that's worth doing before deciding where this $10,000 goes.

The annoying answer is that any of them could be right. Because the best place for your $10,000 isn't necessarily wherever you can get the highest return. It depends on what you actually need that money to do.

So let's put the same $10,000 through the options.

First, Is This Actually Spare Money?

Before deciding where your $10,000 should go, there's a more important question: Can you actually afford to do anything with it?

There's a big difference between having $10,000 and having a spare $10,000.

If you've got $5,000 sitting on a credit card charging you a huge amount of interest, worrying about whether an ETF might return 7% or your savings account pays 5% is solving the wrong problem.

The same goes if that $10,000 is every dollar you have. A share portfolio isn't particularly helpful when your car dies, the hot-water system gives up or you suddenly find yourself without an income.

As a general starting point, Moneysmart suggests having access to around three months of household expenses as emergency savings. The right amount will depend on your circumstances.

So before doing anything else, ask yourself:

Do I have expensive debt?
Do I have some emergency savings?
Am I going to need this money soon?

If the answer to any of those changes your situation, deal with that before worrying about which option has the prettiest return on a spreadsheet.

Option 1: Put It in Your Mortgage Offset

The boring option that's pretty hard to beat.

First things first: this only applies if you have a home loan with an offset facility. If you don't, skip ahead.

An offset is essentially a transaction account linked to your home loan. Instead of earning interest on the money sitting there, the balance reduces the amount of your mortgage that the bank charges interest on.

Let's keep the maths simple.

Mortgage: $500,000
Mortgage rate: 6%
Money in offset: $10,000

While the full $10,000 is sitting there, the bank effectively calculates interest as though your mortgage balance were $490,000.

If the $10,000 stayed there for the entire year and the mortgage rate remained at 6%, you'd save roughly $600 in mortgage interest.

That's not bad for money that's still sitting in an account you can access.

The Part People Sometimes Miss

That $600 isn't interest the bank paid you. It's interest you didn't have to pay the bank.

That matters because interest earned through a savings account generally forms part of your taxable income. The saving from your offset isn't bank interest income. It's simply an expense you avoided.

So a savings account paying 6% and an offset against a 6% mortgage aren't necessarily the same deal.

Offset and Redraw Aren't the Same Thing

They're often talked about as though they're interchangeable, but they're not.

An offset is a separate account containing your money. A redraw facility generally lets you access extra repayments you've already made against your mortgage. How easily you can get that money back depends on your lender and loan terms.

One Thing Worth Checking Tonight

Make sure your offset is actually linked to your mortgage.

It sounds ridiculous, but ASIC recently found cases where customers' offset accounts weren't being managed correctly, meaning some people paid more mortgage interest than they should have. Banks have paid over $55 million in compensation to customers for offset account failures.

You can usually check through your banking app, online banking or statements. If you've refinanced or changed loan products, it's particularly worth checking that the link is still working.

Also check what you're paying for the feature. Some loans with offsets come with higher interest rates or additional fees. If you're paying hundreds of dollars every year for an offset you barely use, the maths may not stack up.

Best suited to: people with a home loan and offset facility who want to reduce mortgage interest while keeping access to their money.

Option 2: Leave It in a High-Interest Savings Account

Sometimes doing nothing is actually doing something.

Cash gets a bad reputation in investing circles. But sometimes cash is exactly what you need.

Hypothetical example: Say your savings account pays 5%. Your $10,000 would earn $500 over a year before tax. Bank interest generally forms part of your taxable income, so that doesn't necessarily mean $500 lands in your pocket after tax.

But a savings account has one enormous advantage: you can use the money when you need it.

If you're buying a home next year, replacing your car in six months or going travelling, that matters.

Imagine putting your house deposit into shares because you wanted a better return, then the market falls just before you're ready to buy. Long-term averages aren't much comfort when you need the money next month.

That's why the question isn't simply "Which option makes more?" It's also "When am I going to need this money?"

If the answer is relatively soon, keeping it accessible can be far more important than squeezing out the highest possible return.

What About a Term Deposit?

A term deposit lets you lock your money away for a set period at a fixed interest rate. That could make sense if you're thinking: "I need this $10,000 in two years, but I definitely don't need it before then."

The trade-off is flexibility. Getting the money out early can involve restrictions or lost interest.

It's not exciting. But neither is watching the money you need next year fall 20% because you put it somewhere it didn't belong.

Best suited to: emergency savings, short-term goals and money you're likely to need within the next few years.

Option 3: Invest It

More potential upside. More uncertainty.

Now we get to the option everyone online wants to talk about.

Hypothetical example: Say you invested $10,000 into a diversified investment and, purely for illustration, it averaged 7% a year. If that return compounded:

After 1 year: approximately $10,700
After 10 years: approximately $19,700
After 20 years: approximately $38,700
After 30 years: approximately $76,100

That's why investing gets people's attention.

But there's an important catch.

The Market Doesn't Give You 7% Every Year

One year you could be well up. Another year you could be down. The 7% example is just an illustration. It isn't a forecast and the figures above don't account for tax, investment fees or inflation. Actual returns will vary and can absolutely be negative.

So instead of asking "Will shares make more than my offset?" ask "When am I actually going to need this money?"

If there's a good chance you'll need the $10,000 within the next couple of years, putting it into shares means accepting the possibility that the market could be down right when you need to sell.

If it's money you genuinely don't expect to touch for a decade or more, those short-term ups and downs matter a lot less. That's when investing becomes a much more interesting conversation.

And investing doesn't have to mean picking three companies and hoping you've discovered the next big thing. A diversified fund or ETF can spread your money across many investments rather than having everything riding on a handful of companies. Moneysmart recommends considering your goals, how long you're investing for and how comfortable you are with the possibility of losing money.

You don't need to become the bloke at the barbecue explaining why one mining stock is about to "absolutely take off."

Best suited to: money you won't need for a long time and people comfortable watching the value move up and down along the way.

Option 4: Put It Into Super

Potentially great tax treatment. One massive catch.

Super is where this comparison gets interesting. Because putting extra money into super can come with tax advantages that you don't necessarily get from investing the same money outside super.

If you make certain before-tax contributions into super, including salary sacrifice, that money is generally taxed at 15% inside the fund rather than being taxed like the salary you would otherwise receive. For many Australians, that can be a lower tax rate.

That's part of what makes super so powerful over a long period.

But there's a rather large catch: you generally can't just take the money back out.

Put $10,000 into a savings account and you can change your mind next month. Invest $10,000 outside super and you can generally sell the investment if you need to, even if doing so at the wrong time might mean taking a loss. Put money into super and it's generally being put away for retirement unless you meet specific rules allowing earlier access.

That's a very different trade-off.

Don't Just Dump $10,000 Into Super Without Checking Your Cap

There's also a limit to how much you can contribute at the concessional rate. The general concessional contributions cap is currently $32,500 a year (from 1 July 2026, up from $30,000 in 2025-26).

Importantly, that doesn't mean you necessarily have another $32,500 available to contribute yourself. Your employer's compulsory super contributions already count towards that cap, as do salary-sacrifice contributions and personal contributions you claim as a tax deduction. Some people may also have unused cap amounts available from earlier years, depending on their circumstances.

So check your position before moving a large lump sum.

Buying Your First Home? There's an Exception Worth Knowing About

For eligible first-home buyers, the First Home Super Saver Scheme changes the conversation.

The scheme allows eligible voluntary contributions made into super to later be released toward your first home. Currently, up to $15,000 of eligible voluntary contributions from any one financial year can count towards the scheme, up to $50,000 across all years.

For eligible salary-sacrifice or tax-deductible contributions, generally 85% of those contributions can form part of the amount available for release, plus associated earnings calculated under the scheme.

So if you're saving for your first home, the decision isn't necessarily "super OR house deposit." Super can potentially form part of the house-deposit strategy. The rules matter though, so don't move money into super purely because you read one paragraph about FHSS.

Best suited to: money genuinely intended for the long term and eligible first-home buyers who understand how FHSS fits into their plans.

Option 5: Invest in Yourself

The option nobody puts in the calculator.

Here's one that gets ignored in most comparisons.

Hypothetical example: Say there's a qualification, licence or skill that costs $3,000 and gives you a realistic shot at moving into jobs paying $5,000 more a year.

That doesn't mean spending $3,000 automatically earns you another $5,000. There are no guarantees. But if employers in your industry genuinely value that qualification, it deserves to be part of the conversation.

That might mean:

A professional qualification
A trade ticket or licence
An industry certification
Software or technical training
A skill that opens the door to better-paid work

Especially when you're younger, one of your biggest financial assets isn't necessarily the $10,000 sitting in your bank account. It's the next 30 or 40 years of income you haven't earned yet. Increasing what you earn over that period could matter far more than perfectly optimising whether your existing savings earn 5%, 6% or 7%.

That doesn't mean buying every course advertised to you on Instagram counts as investing in yourself. If someone standing next to a Lamborghini promises their $7,000 course will have you financially free by Christmas, maybe keep the credit card in your pocket.

There should be a realistic connection between what you're paying for and better earning opportunities.

Best suited to: people with a clear opportunity to improve their earning power through a genuinely useful qualification, licence or skill.

What About Just Spending Some of It?

Here's something personal finance content doesn't say often enough: You're allowed to enjoy your money.

If you've got $8,000 of credit card debt and no emergency savings, blowing the whole $10,000 on Europe probably isn't doing Future You many favours.

But if your finances are under control, you don't have to optimise every last dollar. Maybe $9,000 goes toward your financial goals and $1,000 goes toward something you actually want. Or $8,000. Or $5,000.

The point isn't the number. It's that building wealth doesn't require treating every dollar you spend on yourself as a financial mistake.

Money is a tool, not a high score.

You Don't Have to Pick Just One

This might be the most overlooked option of all.

Finance discussions love turning everything into a fight. Mortgage vs shares. Super vs ETFs. Save vs invest. Real life doesn't require you to pick a team.

Someone with $10,000 might decide:

$5,000 toward emergency savings
$3,000 toward a long-term investment
$2,000 toward a holiday

A homeowner who already has an emergency fund might instead decide:

$7,000 toward the offset
$3,000 toward a long-term investment

Those aren't recommendations. They're examples. The point is your $10,000 doesn't have to have one job. You can prioritise security while still investing. You can reduce your mortgage while building investments elsewhere. And you can save for Future You without refusing to spend anything on Present You.

Same $10,000, Four Completely Different Answers

Let's take four Australians with exactly the same amount of money.

Sarah, 24. Sarah rents, doesn't have much emergency savings and wants to travel next year. Putting the whole $10,000 into shares gives her more potential upside, but it also exposes money she's likely to need soon to market movements. First thing for Sarah to consider: keeping enough of it accessible.

Jack, 34. Jack has a mortgage around 6%, an offset facility and an emergency fund already sorted. Putting the $10,000 in his offset could immediately reduce the mortgage interest he's being charged while leaving the money accessible. First thing for Jack to consider: his offset.

Daniel, 29. Daniel rents, has no expensive debt, has his emergency savings sorted and doesn't expect to need the $10,000 for a decade or more. A bad year in the share market doesn't necessarily force him to sell. First thing for Daniel to consider: long-term investing becomes much more reasonable.

Emma, 27. Emma has savings and discovers an industry qualification costing $3,000 that employers in her field genuinely value. Completing it could improve the roles and salaries available to her, although nothing is guaranteed. First thing for Emma to consider: whether some of the money could increase what she earns.

Same $10,000. Four people. Four completely different answers.

What If You Don't Have $10,000?

Nothing magical happens when your bank account reaches five figures. We picked $10,000 because the maths is easy.

The same questions apply if you have $1,000, $5,000 or an extra $200 left after payday. You don't need to wait until you're "good with money" to start making deliberate decisions with it. Start with what you've got.

The 30-Second Test

Before you move the money anywhere, run through this:

Have expensive debt? Start there.
No emergency savings? Build some breathing room.
Have a home loan with an offset? Work out what the offset could save you.
Need the money within the next few years? Think carefully before exposing it to market falls.
Don't expect to touch it for a long time? Investing becomes more worth considering.
Saving specifically for retirement? Look at whether super makes sense.
Could spending some of it realistically increase your income? Don't overlook yourself.
More than one answer applies? You can split the money.
Still don't know? There's no rule saying you have to move all $10,000 today.

So, What Should You Actually Do?

If this sounds like you	Start by looking at	Why
You have credit card or expensive personal debt	Pay down debt	High interest is working against you
You have little emergency savings	Emergency fund	Having accessible cash gives you breathing room
You have a home loan with an offset	Offset	Can reduce mortgage interest while keeping your cash accessible
You'll need the money within a few years	Savings, term deposit or offset	Less risk of needing to sell an investment at the wrong time
You won't need the money for a long time	Diversified investing	You have more time to ride out market falls
You're specifically building retirement wealth	Super	Potential tax advantages, but less access
You're an eligible first-home buyer	FHSS plus accessible savings	Super may be able to form part of your deposit strategy
A qualification could realistically increase your income	Invest in your skills	Higher earnings can benefit you for years
Several of these describe you	Split the money	Your money doesn't need to serve only one purpose

This isn't a ranking. Having a mortgage doesn't automatically mean every spare dollar belongs in your offset. Being 25 doesn't automatically mean you should throw everything into ETFs. And putting money into super isn't automatically smart just because the tax treatment can be attractive.

Start with what the money needs to do. Then choose the tool.

The No BS Verdict

The best return isn't always the biggest percentage on a spreadsheet.

An offset might look boring, but reducing mortgage interest while keeping your money accessible can be a pretty compelling deal. Investing might build considerably more wealth over decades, but you're accepting uncertainty along the way. Super can offer attractive tax advantages, but you're generally giving up access to the money. Investing in your skills might produce a bigger return than any of them.

And sometimes keeping the money in cash is exactly the right decision.

The question isn't "Where will this $10,000 make the most money?" It's "What does this $10,000 need to do for me?"
