Bridging Loan Costs in Australia (2026): Where the Money Actually Goes

Bridging Loan Costs in Australia (2026): Where the Money Actually Goes

Bridging finance is a short-term loan that carries you across the gap between buying your next home and settling the sale of your current one, a definition Moneysmart’s glossary puts in almost exactly those words. Most articles answer the question of what it costs by quoting a rate. We think that is the least useful place to start, because the rate is the one input you cannot see clearly until a lender prices your whole structure. What you can see clearly, before you speak to anyone, is the machinery: what the charges are, which ones are fixed, which ones scale, and which levers you control. That machinery is the subject of this guide. For how bridging works end to end, from peak debt to settlement, read our complete guide to bridging loans in Australia alongside this one.

What actually drives the cost of a bridging loan?

Strip away the fee names and a bridging loan has one dominant cost: interest on your peak debt, accruing for as long as the bridge runs. Peak debt is everything you owe while you hold both homes: your existing mortgage balance, plus the new purchase price, plus the buying costs, plus the interest that builds up along the way. That balance is the largest amount of money you will ever owe in the process, and every month on the bridge charges interest on it.

So the two levers are simple. Lever one is size: the bigger the peak debt, the more each month of the bridge costs. Lever two is time: the longer your old home takes to sell, the more months of interest accrue on that peak. Terms typically run 6 to 12 months in Australia, and the difference between the short end and the long end of that range is not a rounding error, it is months of interest on your largest ever balance.

Everything else you will be charged, and we itemise all of it below, is a setup cost that behaves much the same whether your bridge runs two months or ten. That distinction, the metered cost versus the fixed costs, is the single most useful idea in this article, and it explains almost every practical decision that follows.

Every bridging cost, itemised

Here is the complete list of what you pay on a bridging loan, described by character rather than by dollar figure, because the figures vary by lender, state and scenario while the machinery does not.

Capitalised interest

The main event. During the bridge, interest on your peak debt is usually capitalised: added to the loan balance each month rather than paid from your salary. You typically make no repayments during the bridging period. When your old home sells, the proceeds clear the accumulated interest along with the rest of the bridge, and the remaining balance becomes your end debt, an ordinary home loan. Because the interest joins the balance, later months accrue interest on earlier months’ interest, which is another reason the time lever matters. This cost scales with both levers: peak debt and months.

Establishment and application fees

A one-off charge from the lender for setting up the facility. It is broadly fixed: it does not meaningfully shrink because your bridge is short, and it does not balloon because your peak debt is large. On a long bridge it disappears into the interest bill; on a very short bridge it becomes a noticeable share of the total, which is a point we return to below.

Two valuations

A standard purchase needs one valuation. A bridging loan needs two, because the lender holds both properties as security: the home you are selling and the home you are buying. Valuations are priced per property, so this cost is effectively fixed, and it is one more fixed line that a shorter bridge does not reduce.

Legal and discharge costs on the old loan

Your existing mortgage has to be paid out and formally discharged when the old home sells. That involves a discharge fee from your current lender and the usual legal and registration steps. Fixed in character, modest in scale, and easy to forget when you are budgeting, because it belongs to the loan you are leaving rather than the loan you are getting.

Stamp duty on the new purchase

Not a bridging fee at all, but it belongs on the list because it is usually the largest single transaction cost in the whole changeover and it is commonly funded inside the bridge. Stamp duty scales with the purchase price and varies by state, exactly as it would on any purchase. The bridging twist is mechanical: when duty is added to the loan rather than paid from savings, it becomes part of your peak debt, and it quietly accrues interest for the life of the bridge.

Why a shorter bridge is not automatically proportionally cheaper

It is tempting to assume a three month bridge costs half of what a six month bridge costs. It does not, and the table above shows why: only one line on it is metered by time. Halve the term and you halve the capitalised interest, but the establishment fee, both valuations, the discharge costs and the stamp duty are exactly the same size on day one as they would be on a ten month bridge. The fixed costs do not care how fast you sell.

The practical consequence runs in two directions. On short bridges, the fixed fees dominate: they become a large share of a small total, so the loan’s cost per month looks worst precisely when the loan is briefest. On long bridges, the interest dominates and the fixed fees fade into rounding. Neither is a reason to avoid bridging; both are reasons to judge the structure on its total cost over your realistic timeline, not on any single fee or any single month.

There is a second trap inside the first. Chasing an artificially short bridge, by accepting a low offer on your old home just to end the interest meter, usually costs more than it saves. The sale price of your existing home moves the outcome by far more than an extra month or two of interest does, because the sale proceeds are what determine your end debt, the loan you keep for years after the bridge is forgotten. A shorter bridge at the cost of a weaker sale is very often the expensive option wearing a thrifty disguise.

Worked example: where the money goes on a 6 month bridge

This walkthrough reuses the live worked example from our bridging loans guide, with the bridge assumed to run around six months. It is illustrative, not a quote. You own a home worth $1,200,000 with a $400,000 mortgage, and you buy a $1,800,000 home before selling.

Now read the table the way a banker reads it. Almost everything on it is money you would owe in any buy then sell changeover: the existing mortgage was already yours, and the purchase line, costs included, is what buying the new home requires however you finance it. The only line that exists because this is a bridging loan is the capitalised interest, roughly $70,000 accrued across the bridge in this illustration, and it is cleared in full by the sale proceeds the moment the old home settles. The peak debt of $2,230,000 looks frightening, but it is temporary scaffolding: nobody expects you to service it, and it stands only until the sale. What you actually live with afterwards is the end debt of around $1,130,000, an ordinary mortgage assessed on your income. The bridging specific cost of the whole exercise is the interest line, and both of its levers are visible right in the table: the size of the peak it accrued on, and the months it was given to run.

How to keep a bridging loan cheap

Every genuine saving on a bridging loan comes from working one of the two levers, or from keeping fixed costs from compounding. In practice that means four habits.

• Price the old home realistically. This is the biggest lever there is. Every week your home sits on the market at a dream price is another week of interest on your peak debt, and in a softening market the honest price and the cheap price are the same number. Our guide to upgrading in a falling market works through why the home you are selling and the home you are buying rarely move in step.
• Be sale ready before you buy. A short bridge is not achieved by hoping. It is achieved by having the agent appointed, the styling and photography planned, and the campaign ready to launch the week you commit to the purchase. Idle weeks at the start of a bridge cost exactly what slow weeks at the end cost.
• Plan the end debt, not just the bridge. The bridge is temporary; the end debt is the loan you live with for years. Structure it deliberately from day one, because once the bridge clears, it behaves like any other home loan, and everything in our plain English refinancing guide applies to it.
• Capitalise only what you must. Costs folded into the loan accrue interest for the life of the bridge. If paying the valuations or fees from cash is comfortable, the peak stays smaller and the meter runs on a lower balance. If cash is tight, capitalising is exactly what the structure is for; just make the choice knowingly.

Why we do not publish bridging interest rates

You will notice this article, unlike most of what ranks for this search, contains no interest rates. That is deliberate, and the reason is worth understanding because it tells you how bridging is actually priced.

Bridging is scenario priced. The rate a lender offers depends on the structure it is being asked to fund: whether the bridge is open or closed, the term, the loan to value ratio across both securities, lenders generally allowing up to around 80% LVR across the two properties, how the end debt services against your income, and whether interest is fully capitalised. Two borrowers asking the same question can carry two very different structures, and they will be priced differently for good reasons. A single rate published on a website is priced for the cleanest imaginable file, which is to say, probably not yours and probably not ours.

So we price the structure instead. Ahmed is a former banker: he builds the peak debt and end debt first, stress tests the timeline, and only then talks about rate, because by that point the rate finally means something. Any guide that quotes one bridging rate for everyone is describing somebody else’s loan. We would rather show you the maths on yours.

Run your own numbers

The two numbers that drive everything in this article, peak debt and end debt, take about a minute to estimate for your own situation. Our bridging guide includes a peak debt and end debt calculator: enter your home value, loan balance, purchase price and buying costs, and it does the two number arithmetic in your browser, with nothing stored or sent anywhere. Run your scenario, then look at the size of your peak debt and ask the two lever question: how many months am I comfortable carrying this, and what would shorten it?

Bridging loan cost FAQ

What drives the cost of a bridging loan?

Two levers: the number of months you spend on the bridge and the size of your peak debt, which is your existing mortgage plus the new purchase and its costs. Interest accrues on that peak debt for the life of the bridge, so a bigger peak or a longer bridge means a bigger bill. The remaining costs are mostly fixed setup fees.

What is capitalised interest on a bridging loan?

Capitalised interest is interest that is added to the loan balance during the bridging period instead of being paid monthly. It accrues on your peak debt while you hold both properties and is cleared when your existing home sells and the proceeds are applied to the loan. It is usually the largest single cost of a bridging loan.

Do I make monthly repayments during the bridge?

Usually no. Most bridging structures capitalise the interest, so it is added to the loan rather than paid from your salary, and some lenders set aside an interest budget within the loan so nothing leaves your pocket during the bridging period. Once the old home sells, the remaining end debt reverts to normal principal and interest repayments.

Why does a bridging loan involve two valuations?

Because the lender holds both properties as security, it values both: the home you are selling and the home you are buying. Each valuation is priced per property, which is why bridging carries one more valuation than a standard purchase. Lenders generally allow up to around 80% LVR across the two properties combined.

Can bridging costs be added to the loan?

Generally yes. Interest is usually capitalised into the loan by design, and buying costs such as stamp duty and legals are commonly funded within peak debt rather than paid from savings. The limit is the LVR cap across both properties, usually up to around 80%, so the more costs you add, the more equity the structure needs.

How long does a bridging loan usually run?

Typically 6 to 12 months in Australia. The term matters because time on the bridge is one of the two cost levers: every extra month adds another month of interest on your peak debt. Selling the existing home sooner shortens the bridge and directly shrinks the interest that capitalises.
