What refinancing break-even does and does not show
The calculator compares amortizing payments on the remaining balance, then divides refinancing cash costs by any monthly payment reduction. It also compares total modeled payments over the stated terms.
- Break-even divides upfront cost by monthly payment reduction.
- A shorter term can raise the payment while reducing total cost.
- Compare lock-in periods, legal charges and product conditions.
Break-even needs both a time and a staying plan
Recovering transaction costs only matters if the new facility remains active beyond that month.

Use the remaining balance and term
A refinance decision begins today, not at the original purchase. Enter the current principal and years remaining so past costs are not counted again.
Use the proposed effective rate, term and all compulsory legal, valuation, discharge and administration costs. A headline rate without transaction costs cannot establish break-even.
Compare term changes beside payment changes
Extending the term can lower the payment even when lifetime cost rises. Shortening the term can raise the payment while reducing total cost, which makes a simple payment-based break-even less useful.
Read the monthly difference, cost recovery month and total modeled cost together. If the new payment is not lower, judge the offer through term, risk and total cost instead of forcing a break-even result.
Check whether the household will stay past break-even
A cost-recovery month matters only if the facility remains in place beyond it. A planned sale, another refinance or an early-settlement charge can prevent the savings from being realized.
Stress-test a rate change when either facility can reprice. Verify lock-in terms and product flexibility from current written documents before acting.

Common questions about this calculator
What does a simple break-even month mean?
It is the upfront refinancing cost divided by monthly payment savings. It does not capture every term change, rate risk or early-settlement condition.
Can a refinance be useful when the payment rises?
Possibly. A shorter term may raise the payment while lowering total financing cost, so compare complete term and cost instead of payment alone.
