Short answer: Fee for ending fixed mortgage early. Depends on rate changes since you fixed. Can be zero or thousands.
If you end a fixed-rate mortgage early, the bank charges a break fee. It covers the interest they expected to earn. If rates have risen since you fixed, the fee might be small or zero. If rates have fallen, the fee can be thousands. Always ask for the break fee before breaking. Sometimes refinancing saves money despite the fee.
Fixed Rate: 6.5%
Current Rate: 7.0%
Rate Difference: +0.5%
Break Fee: $0 (rates rose)
Alternative Scenario: If current rate 5.5%, fee could be $8,000
