Formula used

Monthly payment = P × r ÷ (1 − (1 + r)^−n). Current interest uses the remaining balance minus any offset balance. New-loan interest uses the offered rate, or a weighted split between the new rate and current rate when split-loan mode is selected. Total upfront cost = discharge fee + fixed-rate break costs if selected + early repayment penalty + valuation fee + legal costs + establishment fee + rate-lock costs. Break-even month = first month where cumulative interest saving reaches total upfront cost, plus any processing delay expressed in months.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for a first-pass refinance decision where the main question is whether the rate saving covers the cost of switching before the loan ends.

  • The comparison keeps the same starting balance for both loans.
  • Rates are treated as fixed nominal annual rates converted to monthly periods.
  • Switching costs are treated as upfront costs, not rolled into the new loan.
  • Offset balance reduces the current-loan interest path only; offset, redraw and package-account features on the new loan are not modelled.
  • Term restructure uses the new term for the new-loan payment while the comparison still reports savings over the current remaining term.
  • Split-loan mode treats the fixed portion at the new rate and the variable portion at the current rate as a simplified weighted interest comparison.

Master’s Tip

How to use the result well

Master's Tip: a lower rate is not enough by itself. Print the cost line, payoff date, break-even month and total remaining interest saving before switching lenders.

Method

Monthly payment = P × r ÷ (1 − (1 + r)^−n). Current interest uses the remaining balance minus any offset balance. New-loan interest uses the offered rate, or a weighted split between the new rate and current rate when split-loan mode is selected. Total upfront cost = discharge fee + fixed-rate break costs if selected + early repayment penalty + valuation fee + legal costs + establishment fee + rate-lock costs. Break-even month = first month where cumulative interest saving reaches total upfront cost, plus any processing delay expressed in months.

  1. A $580,000 balance at 6.15% with 240 months remaining compared with 5.79% has about $174 first-month interest saving. With $1,050 total switching costs and a 21-day processing delay, the practical break-even is about month 8. If valuation, legal, break or rate-lock costs change, the break-even month moves with them.

Assumptions

  • The comparison keeps the same starting balance for both loans.
  • Rates are treated as fixed nominal annual rates converted to monthly periods.
  • Switching costs are treated as upfront costs, not rolled into the new loan.
  • Offset balance reduces the current-loan interest path only; offset, redraw and package-account features on the new loan are not modelled.
