Comparison is rate-only. A complete refinance call also weighs term, redraw, offset, fixed vs variable, and exit triggers. Speak with an accredited broker before deciding.
Assumptions
  • Both loans are interest only on a flat balance, at the rates entered, for the whole window.
  • Switching costs are the amount entered, paid at the start of the new loan.
  • The serviced P&I figures are a reference only: equal monthly payments that repay the balance over the window.

Illustrative estimate only, based on the inputs and assumptions shown. This is not a quote, credit approval or commitment to lend. Actual interest, fees, repayments and terms may differ. Costs not included are listed below.

Costs not included
  • Break costs and discharge fees on the current loan, unless you include them in switching costs
  • Lender fees, legal, valuation, settlement and government registration costs, unless you include them in switching costs
  • Default interest, default fees and enforcement costs

How the comparison works

The calc uses interest-only monthly cost (balance times rate divided by twelve) for the like-for-like total, which is correct for short-dated private files that don't amortise. For borrowers servicing P&I, both serviced figures are shown alongside as a reference. The break-even line is switching costs divided by the monthly saving; if the new rate is not cheaper, no break-even fires.

When refinancing private to private makes sense

When the original facility was sized for a 6-month bridge but the underlying transaction has extended to 18 months. Or when the original lender will not extend at a rate that reflects the de-risked file. Refinancing within private credit is normal and often cheaper than rolling the same facility. Speak to an accredited broker about whether your file fits.
