Bills we can compare—

Could save per year—

"Could be" figures use today's lowest rate or plan in each category for a typical household (7,000 kWh of power, fibre 300, 12 GB mobile). Insurance isn't estimated here because it depends on your cover; use the insurance tool instead.

When does your fixed rate end?

End of fixed term

Balance at that date

Rate you're on now

Banks let you lock a new rate up to 60 days before your term ends, and they'll usually honour the lower of the locked rate and the rate on the day. That window is where the money is.

Is it worth breaking your fixed rate?

Bank's wholesale rate for the time left

Banks calculate break fees from the drop in wholesale (swap) rates since you fixed, not from carded rates. We've pre-filled a typical figure; your bank will quote the exact fee free of charge, and the quote is only valid on the day.

Estimated break fee—

Interest saved till your fix ends—

Net result—

Estimate only. Formula: break fee ≈ balance × (your fixed rate − wholesale rate for the remaining term) × years remaining, discounted. Some banks offer a cash contribution when you refix that can offset the fee; ask. Not financial advice.
