Should I Break My Fixed Mortgage?

Rates have dropped and you're still locked into a higher fixed term. Is it worth paying the bank's break fee to refix lower now, or better to sit tight until your term ends? This weighs the interest you'd save against the fees you'd pay, over the months you have left. Everything stays in your browser.

Documentation to refix

Keeping the old (higher) repayment after refixing lower puts the difference straight onto principal, so you pay the loan down faster.

Each line is the cumulative interest (plus one-off fees for breaking) paid so far. Breaking starts higher because of the fees, then rises more slowly at the lower rate. Where the lines cross, the fees have paid for themselves — after that, breaking is ahead.

Our Recommendation

Breaking looks worthwhile — refixing at 5.79% saves roughly $8,996 of interest over the remaining 18 months, which clears the $3,750 in fees and leaves you about $5,246 better off. The fees pay for themselves after about month 8. Ask your bank for a written break-cost figure before committing — it moves with wholesale rates.

Informational only, not financial advice. The break fee is an estimate — only your bank can calculate the exact figure, and it changes daily with wholesale rates, so always get it in writing before deciding. This compares interest and fees over the remaining fixed term only; it doesn't model what rates do after your term ends.
