I have a vague idea that instead of paying into a public sector pension (if the increase occurs) to instead pay off an extra £300 per month (mortgage is £1100 per month over 25 years)
I need to work out how many months it will knock off the term and also how much less interest i will pay over the term.
Ball park figures are about £25k less interest and 5-6 years less term. so in real terms about £100k could be saved up in the term at the end of the new term until the old term would have finished. Does thats ound right? Interest rate is about 4%
