Breakeven point
The year the cheaper-so-far loan stops being cheaper, if that ever happens.
No breakeven over the term
Scenario B stays ahead on cumulative total paid for every year of the loan. There's no breakeven, so the lead is permanent.
Loan balance over time
What is still owed at the end of each year.
Cumulative interest paid
Interest adds up fastest in the early years, while the balance is highest.
Fees, offsets, redraws, and rate changes after rollover are not modelled; results are a clean like-for-like comparison of repayment structures. Default rate as of September 2026.
