Hi,
This was a real pain to work out I hope this is helpful???????????;0)
130000 mortgage at fixed 5.59% for 2 years mortgage over 30 years, this illustration includes the period of SVR after the fixed rate ends.
Repayment 750p.m Balance after 5 years 121,080
I.O. 605p.m Balance after 5 years 130,000
Saving over 5 years on I.O.= 8,700 Balance paid off after 5 years on repayment = 9,020
Difference = 320
I hope this gives you some idea how things could work for you either way, and whether you would benefit from the 145.00 saving each month??
