Hi, I am with AIB who calculate interest daily. I also pay back my loan every fortnight but with a slight twist. Say your annual mortgage repayment is 15,000 p.a. This works out for most people at 1,250 per month. In this case, if you decide to pay bi-weekly, then pay back 1,250/4*52 per annum. This works out to be an annual mortgage re-payment of 16,250, higher than before! Why? Because there is actually more than 4 weeks in a month. Every 2 weeks, you will pay back 16,250/26 = 625.
Now this is important for 2 reasons:
1. Because if your bank is calculating interest daily (not monthly), you'll save thousands over the term.
2. You won't miss the extra money you are paying because it feels like you are paying the same amount every month. In fact, you're paying an extra month every year.
Banks do not advertise this method for obvious reasons. I was able to shave over 3 years off my term as a result of this.
Don't forget to negotiate your interest rate aswell.
