Mortgage Overpayment Calculator

Written by on 10 Dec 2007

After writing the Mortgage Overpayments article, I decided to put together an overpayment mortgage calculator, so you easily work out how much you can save by making overpayments. The tool calculates how much you can save, along with how much time you will be shaving off your mortgage.

Most lenders allow at least 10% penalty-free overpayments per annum, but it’s important you check with your lender. For more details on mortgage overpayments I would recommend reading the Mortgage Calculator article.

LIBOR stands for London Interbank Offered Rate and is one of the most active rates. LIBOR would be the part of your ARM rate that will adjust and go up or down at each adjustment period, therefore increasing your decreasing your rate and payment.
In addition to the more popular 2 and 3 year fixed period Adjustable Rate Mortgages, there are also ARMs that are fixed for a 5, 7 or 10 year period, and amortized over a 30 year period.
Typically, an ARM will have a fixed period for 2 or 3 years, then will adjust after that.
