Ladies, help is needed as my brain is not what it used to be! We come off a fixed rate mortgage soon and the interest rate will be dropping quite considerably as we will be reverting to the base rate (currently 2.5%). How do I work out what the payments will be, taking into consideration what we are paying now at a rate of 5.98% (even typing that makes me shiver slightly, but 5 years ago a fixed seemed the best option!) I've tried ringing our provider who keep telling me someone will phone me back but they never do and I'm getting impatient! Any savvy finance guru's out there that can help me with the maths?
