Frequently asked questions
Is remortgaging always worth it if the new rate is lower?+
Usually, but check for arrangement fees on the new deal too — a lower rate with a large upfront fee can sometimes cost more overall than a slightly higher rate with no fee, especially over a short remaining term.
What happens if I do nothing when my current deal ends?+
You'll typically move onto your lender's standard variable rate (SVR), which is usually noticeably higher than any fixed or tracker deal — this is exactly the gap this calculator is built to quantify.
Can I remortgage before my current deal ends?+
Yes, but you'll likely pay an early repayment charge unless you're within your lender's penalty-free switching window (often the last few months of your deal) — enter that charge in the exit fee field to see if switching early still pays off.
