Offset, redraw and paying your home loan off faster

The short answer

If you've got a home loan and your savings are sitting in a savings account, just stop. The money needs to be in one of two places: an offset or the loan itself.

Offset and redraw save you exactly the same interest while the money sits there. Where they differ is what happens the day you take it out, and that difference only really bites if the property might become a rental one day. Paying extra is the whole game on a variable loan and a capped one on a fixed loan. And the fastest way to pay a loan off has nothing to do with features at all: it's keeping your repayment where it is when the bank gives you a reason to drop it. This page is all of that, in order, with the full answer to each question one click down.

How interest is actually charged

Every feature on this page comes back to one piece of plumbing, so it's worth getting straight first. The bank works out your interest on the balance you owe, day by day, and adds it to the loan once a month. Not on the loan you signed up for. On what you owe today, tonight, and again tomorrow.

That's why timing matters more than people expect. A dollar that sits against the loan for the whole month saves you a month of interest on that dollar. A dollar that arrives on the last day saves you one day's worth. And a dollar sitting in a savings account at a different bank saves you nothing at all, while you pay tax on the little bit of interest it earns over there. The way I put it on every call: think of your offset as your new savings account, because it's interest saved, not interest earned, so there's no tax component. Your money is almost working fifty percent harder in an offset.

Offset and redraw are two different ways of putting the same dollar against the same balance. With redraw, the dollar goes into the loan and the balance drops. With an offset, the dollar sits in a separate account and the bank charges interest on the loan balance less what's in the offset. Illustrative, not a quote: $500k owing and $25k of spare cash gets you interest charged on $475k either way. Same interest saving, different plumbing. Everything else on this page is about what the plumbing does when you want the money back.

Offset, redraw or savings account

If you don't have a home loan yet, the first two aren't applicable. Offset and redraw only exist once there's a loan for them to work against, so your savings account is the right place until then. A first home buyer could also look at the super saver scheme as a way to build the deposit, but that's a separate question.

Offset is the flexible one. It's a separate account. It doesn't co-mingle with the loan, it can come with a debit card, and a lot of loans let you run several of them so you can bucket your money: bills, holiday, the shit-hits-the-fan fund, all offsetting the mortgage at once. The trade is that a loan with an offset usually carries a monthly or annual fee, and plenty of people are happy to pay it for the flexibility.

Redraw is the no-frills one. Your extra money goes straight onto the loan, the balance drops, and you can pull it back later if you need it. It usually comes on the cheaper, no-annual-fee loans. For someone who doesn't need buckets or a card and just wants the cheapest possible loan, redraw is the better deal, and the full comparison lands there for a lot of people.

The one warning. Pulling money out of redraw changes what that money is, from the loan's point of view. It's new borrowing, and the purpose of new borrowing is what an accountant looks at. On the home you live in, that barely matters. On an investment property it's the whole story: a $500k investment loan with $25k paid in and then redrawn for a car becomes a $475k property loan with a $25k car loan attached, in one facility, under one account number. That's why investment loans get an offset, not redraw. How the interest on any part of your loan is treated for tax is your accountant's call, not mine. What I can do is set the loan up so the question never has to be asked. If a future rental is even a maybe, offset keeps your options clean.

The available balance illusion. When a client tells me their balance, the next thing I ask is whether there's an amount that says available. That available amount is your redraw: the extra repayments and lump sums you've put in that the bank will let you take back. Balance $420k, available $35k means you owe $420k today and you're $35k ahead of where the minimum would have you. Yes, in most cases it's money you can spend. But it's still sitting inside a bank product with the bank's rules around it, and the moment it matters most is when you change lenders, because you get asked whether to keep it as cash or let the loan shrink for good.

Paying extra: what it does and what it doesn't

On a variable loan, there's generally no penalty for paying as much as you like. Pay it off in full tomorrow, put money in, pull money out. That's the trade you make for a rate that can move: the bank doesn't lock you in, so it doesn't charge you for leaving early or paying down faster. Every extra dollar cuts the interest you're charged next month, and the full answer on penalties is that short for variable.

On a fixed loan, there's a cap, and the cap is the whole point. Each bank sets its own limit on additional repayments during the fixed period, some per year, some across the whole term. It's typically a modest figure, enough for the odd bonus or tax refund, not enough to pay the loan off. Go over it and break costs can come into it, and they can be expensive, because the bank locked in its own funding for that term and you've left it out of pocket. So before you throw a lump sum at a fixed loan, find the cap in the contract or ask for it. If the lump sum is bigger than the cap, it might be better in an offset on a variable split, or held until the fixed period ends. This is the big reason a lot of people run a split: part fixed for certainty, part variable with an offset so the extra money has somewhere to go.

What paying extra actually does is shorten the loan from the inside. The term on the contract doesn't change. What changes is how far ahead of the schedule you are, and a loan that's consistently paid ahead simply finishes early. That's the mechanism behind every "pay it off faster" tip you've ever read, and none of the tips beat the plain version: pay more than the minimum, as often as you can, for as long as you can.

The fastest version costs nothing extra. Twice in the life of a loan the bank hands you a lower minimum repayment, and both times the winning move is to ignore it. The first is a rate cut. Your minimum often won't drop on its own, because reducing it means changing the terms of your contract and most banks want you to ring and ask. If you're comfortable paying what you're paying now, don't ring. The lower rate shows up as extra money going into your loan instead of into your account, and on a $500k loan that quietly takes years off the term. You're not doing anything clever. You're just not spending a pay rise you didn't ask for. The second is a refinance. The application form defaults to 30 years, and if nobody changes it, five years of progress on the old loan turns into 35 years of repayments across the two. It doesn't have to go back to 30: match the remaining term, shorten it, or reset to 30 and keep paying the old amount. On $500k with 25 years left, the gap between the two minimums is around $200 to $250 a month across a spread of example rates, illustrative, not a quote, and every dollar of that gap paid over five extra years is interest. The longer term is not what costs money. Paying the longer term's minimum is.

One small thing on weekly repayments, since everyone asks for the weekly number. Some banks quote a true weekly figure: monthly, times 12, divided by 52. Others quote an accelerated weekly figure: monthly divided by four. Four weeks a month sounds right, but there are 52 weeks in a year, not 48, so accelerated weekly has you paying the equivalent of thirteen months a year. It's a quiet way of overpaying without noticing, which is fine if you meant to, and worth knowing about if you're comparing two loans on their weekly numbers.

One loan or several

Rule one: anything borrowed for an investment purpose stays as its own loan. Full stop. If you've pulled money out to buy an investment property, and I put that loan together with the loan for the place you live in, your accountant is not going to be very happy with me. Working out how much of the interest belongs to which purpose becomes a spreadsheet exercise for the rest of the loan. So loans get split by purpose: owner-occupied in one, investment in another. That's not a preference, it's the line the tax office cares about.

Rule two: split by what you want to pay off fast. Sometimes people pull money out for a car. We keep the original home loan and set up a separate split that is the car money, so they know which is which and can focus on clearing that one first. You're not paying off a car over 30 years. Same for a renovation: a separate $40k split lets you see exactly how quickly it's going, and the difference between five years and thirty on that slice is real money.

When one loan is the right answer. If everything is owner-occupied purpose, for a lot of people it all sits in one: one rate, one repayment, one offset doing the work. There's nothing to gain from splitting a loan that was only ever for the house you live in. The time to revisit it is when the purpose changes: you pull equity for something new, or you move out and the place becomes a rental. Splits are a filing system, not a saving. They don't change what you owe or what you pay on it. They change what you can see, and for some people that visibility is exactly what gets the car money gone in three years.

Same loan, different lender, different answer

Here's the part a comparison table never shows you: every one of these features is set by each lender on its own terms. Two loans with "offset" in the product name can behave completely differently the day you need them to.

Take offset on a fixed rate. Some lenders offer a partial offset on fixed loans, where only a slice of your balance counts. Many offer none at all. If your savings sitting against the loan is a big part of how you manage money, fixing the whole lot at the wrong lender can switch that off for the entire fixed term. Take multiple offsets. Some products let you run several accounts against one loan, which is what makes bucketing work. Others give you one. Take redraw itself. Some banks let you redraw online in a day or two. Some have minimum amounts. Some charge a fee to redraw on a fixed loan. And a couple can reduce the available amount without much notice if the loan is in arrears, which is the single best argument for keeping your emergency money in an offset rather than inside the loan.

Take extra repayments on fixed. The cap is a different number at every lender, set per year at some and across the whole fixed period at others, and the break cost for going over it is calculated by each bank against its own funding, so nobody can tell you in advance what it'll be. Take the investment side. Not every investment loan comes with an offset: basic products often have redraw only, and if an offset is the point, it has to be part of the product choice on day one, not a request after settlement.

None of that is a reason to pick the loan with the most features. It's a reason to pick the loan whose features match how you actually run your money, and to know that we date lenders, we don't marry them. If the structure stops fitting, it moves.

The questions, one by one

Each of these has its own full answer, in the order they tend to come up. Find where you're at and go down a level.

Offset, redraw or savings account: where should my money sit?

Not in savings, if you've got a home loan. Offset is the flexible one with buckets and a card, redraw is the no-frills one on the cheaper loan. One warning if the property might become a rental.

Can I pay extra off my home loan? Is there a penalty?

Variable, generally no penalty at all. Fixed, there's a cap on extra repayments set by each bank, and going over it can trigger break costs. Know the cap before the lump sum lands.

Is the available balance on my home loan really money I can spend?

Yes, in most cases. It's your redraw: the extra you've paid in that the bank will let you take back. The moment it matters most is when you switch lenders.

Should I combine my home loans into one, or keep them separate?

Investment purpose stays as its own loan, full stop. Beyond that, split what you want to pay off fast and combine what was only ever for the house you live in.

Can I use redraw on my investment loan?

Try not to. Redraw pays the loan down, and pulling it back out is new borrowing with a new purpose. An offset keeps the investment loan exactly what it was. The rest is a question for your accountant.

Does refinancing put me back to a 30 year loan term?

Not unless you let it. The form defaults to 30, and defaults can be overwritten. Match the remaining term, shorten it, or reset and keep paying the old amount.

Do repayments auto-adjust after an RBA cut?

Often, no. The minimum only drops when you ring and ask. If you're comfortable with the current repayment, don't ring: the cut goes straight at the principal instead.

Should I go fixed or variable?

Fixing buys certainty and costs you flexibility: capped extra repayments, limited or no offset, break costs if you leave. Variable buys the opposite. The split loan means you don't have to pick one.

What will my repayments be per week?

True weekly is monthly times 12 divided by 52. Accelerated weekly is monthly divided by four, which quietly pays a thirteenth month each year. Know which one you're being quoted.

The honest part

An offset is not free, and on a small balance it can cost more than it saves. The loan that comes with one usually carries a package or account fee, and if the most you'll ever have sitting in it is a couple of thousand dollars between paydays, the interest that money saves won't cover the fee. For that person, the cheaper no-frills loan with redraw is the better deal, and I'll say so rather than sell the feature. The offset earns its keep when there's a real balance living in it: an emergency fund, a savings pile, salary landing there and bills leaving from it.

The other honest bit is about discipline, because none of this works on its own. An offset with nothing in it saves nothing. A redraw facility you keep raiding for holidays is just a more complicated savings account. A 30 year term you meant to pay like 25 only helps if the extra repayment actually leaves your account every month. The features are plumbing. The habit is the thing. Set the direct debit at the higher number on day one and the plumbing does the rest without you thinking about it again.

Want to know if your loan is set up the right way round?

Send me your latest statement and I'll tell you whether your loan has an offset, a redraw or neither, what the fee is buying you, whether your investment split is clean, and what your repayment should be set at to finish early. If the structure is right, I'll say so and you stay put.

Common questions about offset, redraw and paying off faster

Is an offset account better than redraw?+

They save the same interest while the money sits there. Offset is a separate account with more flexibility, a debit card and often several buckets, and it usually comes with a fee. Redraw is money paid straight onto the loan that you can pull back later, usually on a cheaper loan. Offset is better if the property might ever become a rental, because taking money back out of redraw is new borrowing and that changes the purpose of the debt. Otherwise, pick the one that matches how you run your money.

Is there a penalty for paying extra off my home loan?+

On a variable loan, generally no. You can pay as much as you like, put money in and pull it out. On a fixed loan, each bank sets a cap on additional repayments during the fixed period, and going over it can trigger break costs, which can be expensive because they're the bank passing on its loss on the funding it locked in for you. Find the cap before you make the lump sum, or keep your flexible money on a variable split.

What is the fastest way to pay off a home loan?+

Pay more than the minimum, every month, and don't drop the repayment when the bank gives you the chance to. After a rate cut, most banks leave your direct debit where it is unless you ring, so leaving it alone sends the cut straight at the principal. After a refinance, don't let the term reset to 30 by default: match the remaining term or keep paying the old amount. Keep your savings in an offset or redraw against the balance rather than in a separate savings account, because interest is worked out daily on what you owe.

Should I combine my home loans into one?+

Anything borrowed for an investment purpose stays as its own loan, because blending it with the loan on the home you live in makes the deductible interest a spreadsheet exercise for your accountant. Beyond that, keep a separate split for money you want to pay off fast, like a car or a renovation, and combine the rest if it was all for the house you live in. Splits don't change what you owe or the rate. They change what you can see.

Can I have an offset account on a fixed rate loan?+

Sometimes, and it depends entirely on the lender. Some offer a partial offset on fixed loans where only part of the balance is offset, many offer none at all. If your savings sitting against the loan is central to how you manage money, the usual answer is a split: fix the part you want certainty on and keep a variable portion with a full offset and unlimited extra repayments.

Offset, redraw or savings account: where should my money sit?

The first decision, in full. Just stop leaving it in savings is most of the answer.
