Mortgage refinance calculator guide
WeCovr's mortgage refinance calculator estimates monthly payment differences and break-even timing when refinancing a mortgage. It is useful for quick remortgage scenario planning before deeper advice.
How this mortgage refinance calculator works
The calculator compares a current payment estimate against a new payment estimate using the remaining balance, time left, and two different rates.
It also uses the refinance fees to estimate how long it may take the lower payment to recover those upfront costs.
Uses remaining mortgage balance, years left, current rate, new rate, and fees.
Returns current and new payment estimates.
Shows estimated monthly saving and fee break-even timing.
Why refinance decisions are more complex than payment alone
Early repayment charges, product fees, incentives, changes to term, and whether you add fees to the balance can all change the real value of refinancing.
How to use the result
Use it as an initial screen for whether a remortgage may be worth exploring, then check the full product terms before acting.

FAQs
Does this include early repayment charges?
No. You would need to account for those separately if they apply.
Why can break-even matter?
Because a lower payment is not automatically worthwhile if the upfront fees take a long time to recover.
Can I use this for remortgaging with a changed term?
This version assumes the remaining term stays the same, so it is a simplified scenario tool.
Is refinancing always better when the new rate is lower?
Not necessarily. Fees and other product terms can offset part or all of the saving.
