Person A
Has £100k mortgage at variable rate of 5%. Pays £5k in interest each year.
Person B
Has £100k mortgage at fixed rate 1%
Pays £1k interest each year.
It can’t be any more simple than that 😂
Now try calculating it in reality
Do a real example for both a fixed rate and a variable rate and include all the set up fees, early exit fees and all the other hidden crap for the fixed rate. Then when you have finished do another comparison at the end of the fixed period and see who owes the most on their property and then compare it a further month down the road when Mr Fix pays all the fees again and off you go again. Now calculate it 2 or 3 times assuming they have both moved and tell me where you are.
I am not disagreeing that a fixed rate is not cheaper for MONTHLY PAYMENTS but if you want to move house early, repay more, or anything else the fees are ridiculous. If you have an £800 a month payment on a variable rate over 25 years and you can manage an additional £100 a month you reduce your term by nearly 20% that's nearly 5 years quicker your mortgage is paid off. Banks and Building Society's don't lose money with Fixed Rate Mortgages they make more money that's why they do it. Try to get a genuine Variable Rate Mortgage linked to BOE Base Rates with a daily rate of interest if you don't believe me.
You can overpay on a fixed deal, usually by upto 10% of the total amount per annum. The lower the interest rate, the more capital you pay off via any overpayment. My 5 year deal, fixed at 1.89% had ZERO fees. It cost me nothing, zilch. Ok, you do have to pay a penalty, which decreases year on year, if you wish to move your mortgage. However, the whole point of fixing at such historically low interest rates is to leave it there!
Your argument is completely flawed Kev in all but the most isolated of cases, i.e someone who is constantly moving or paying off a mortgage early or overpay by more than 10% per annum. I can assure you that, unless you fit the above in all cases, you have been paying more interest than you needed to. It has cost you more and the bank has profited more from your borrowing.
There are plenty of online mortgage/interest calculators if you wish to prove me wrong.
