Capitalised LMI Explained: Should You Add LMI to Your Loan?

When LMI is unavoidable, you have two ways to pay it:

1. Upfront — pay the full premium as cash at settlement
2. Capitalised — add the premium to your loan balance

Most Australian borrowers capitalise LMI because it preserves their cash buffer. But that convenience comes at a cost: you’ll pay interest on the LMI for the life of the loan.

Use the LMI Calculator to see the side-by-side cost for your scenario, then read on for the trade-offs.

How capitalising LMI actually works

If your LMI premium is $14,000 and you choose to capitalise:

• Your loan balance increases from $720,000 to $734,000
• Your LVR is recalculated against the new balance — sometimes pushing you into a higher LMI tier (lenders typically allow capitalisation up to 95% LVR after the premium is added)
• You pay the LMI as part of your monthly repayment over 25–30 years

The real cost: an example

Let’s look at a typical scenario: $700k property, $560k loan (80% LVR after premium), 6.24% p.a. interest, 30 years.

	Upfront	Capitalised
Cash at settlement	$14,000 LMI	$0
Total loan balance	$560,000	$574,000
Monthly repayment	$3,438	$3,524
Lifetime interest	$677,500	$694,800
Total cost of LMI	$14,000	$31,300

Capitalising more than doubled the true cost of the LMI premium because you’re paying ~6% interest on it for 30 years.

When capitalising still makes sense

Despite the higher lifetime cost, capitalising is the right choice in several situations:

1. You need the cash for the property itself

Stamp duty, conveyancing, building inspections, moving costs, and immediate repairs can easily total $30k–$50k. If paying LMI upfront leaves you short on settlement, capitalise.

2. You plan to refinance or sell within 5–7 years

The interest cost compounds over decades. If you sell in year 5, you’ve only paid a fraction of the additional interest — and you’ll typically recoup it in property growth.

3. You want to keep an emergency buffer

Mortgage lenders increasingly want to see post-settlement reserves of 3–6 months’ repayments. Capitalising LMI keeps that buffer intact.

4. You can make extra repayments

If your loan allows extra repayments, you can pay down the capitalised LMI quickly to reduce the long-term interest cost. Even an extra $200/month can shave years and tens of thousands off the loan.

When upfront is better

Pay LMI upfront if:

• You have substantial savings beyond the deposit and won’t need them for settlement costs
• You’re on a fixed-rate loan with no extra-repayment flexibility
• You plan to stay in the loan for 20+ years without refinancing
• The upfront amount is small relative to the lifetime interest delta

A common middle ground: partial capitalisation

Some lenders allow you to capitalise part of the premium and pay the rest upfront. This can be useful if you want to keep some cash but are uncomfortable with the full long-term cost.

Ask your broker whether your lender supports partial capitalisation — it’s not always offered.

What about LMI tax deductibility?

For investment properties, LMI is generally tax-deductible over five years (or the loan term, whichever is shorter). This applies whether you pay upfront or capitalise. See our LMI for Investment Property guide for the full deductibility rules.

For owner-occupier loans, LMI is not tax-deductible regardless of how you pay it.

Quick decision framework

Ask yourself:

1. Do I have the cash to pay LMI upfront and settle without stress? If no → capitalise.
2. Will I sell or refinance within 7 years? If yes → capitalising is fine.
3. Can I make extra repayments? If yes → capitalising is manageable.
4. Am I on a 30-year fixed loan with no flexibility? If yes → upfront if you can.

Run your own numbers

The exact cost depends on your loan size, interest rate, and term. Our LMI Calculator shows the upfront vs capitalised comparison automatically — including the lifetime interest impact.

Key caution

The figures in our calculator are indicative. Lenders apply different rates and may recalculate the LMI premium when capitalising (because the higher loan-to-value ratio can push you into a higher tier). Always confirm the final premium with your lender or broker.
