Understanding economic costs on a fixed rate loan (2024)

What are 'economic costs'?

When NAB lends you money for a fixed period of time, we borrow it from the financial markets. This consists of funds from other banks, customer deposits, blue chip investors etc.

The interest rate on the money we borrow is known as the 'cost of funds'. If you make additional repayments, or pay out your fixed rate loan early, the original loan term remains the same. Accordingly, an economic cost is charged to us and this is why we pass this cost on to you.

When could I be charged economic costs?

During a a fixed rate period when you:

make extra repayments
pay out yourloanearly
switch to a different interest rate
switch from a fixed rate loan to a variable rate loan.

Can I make extra repayments?

Some loans allow you to make extra repayments without being charged economic costs. Our NAB fixed ratehome loans, for instance, allow you to make up to $20,000 in extra repayments during a fixed rate period without incurring economic costs.

How are economic costs calculated?

The things NAB will look at include:

the change in the cost of funds since you took out your fixed rate loan
the term remaining in the fixed rate period
the amount you’re repaying.

If the cost of funds drops and you pay off more than the scheduled repayments, you could be charged economic costs.

How much are economic costs?

The cost of funds changes each day—which obviously affects the calculation of economic costs. You'll need to talk to your home loan expert or banker to get a quote. Talk to them before you pay it out or change your loan.

Avoiding economic cost

Economic costs can be considerable so think hard about the pros and cons of a fixed rate loan before you decide to fix it. If you’re hoping to pay your loan off early, then a fixed rate loan mightn't be a great idea.

If you already have a fixed rate loan and you’re thinking about making extra repayments, talk to a home loan expert first.
