This mortgage repayment calculator will help you to find out how much your mortgage will be over your repayment term. This calculator will also show you the differences in the amounts you will have to pay back if you change the length of the mortgage term. Changing the term to a shorter one will cost more in the short term but will cost less over the life of the mortgage. For example if you pay your mortgage off over a five year term you will typically pay 1.17 times value of your mortgage back. When the term is changed to 30 years you typically pay back 2.28 times your mortgage. To use this calculator simply change the light blue variables and press update.
