Hi --- Off the cuff that equates to a charge of 19.4% APR interest
£4895 borrowed over 60 months = £128.06 / month
Total charge for credit = £2788.53
Total Repayment = £ 7683.53
================ ================
At 7% APR it should be £96.93 / month....... (the correct rate)
Total charge for credit = £ 920.61
Total repayment = £ 5815.61
I think you will find they have added loan PPI on top of the finance deal and perhaps added an extended warranty policy, these are NOT compulsory and are expensive ways of them earning profit from you.IF you do want PPI shop around for your own you will find it lots cheaper buying it independently.
Seriously do not sign this agreement until they have given you a full breakdown of everything you are responsible for paying all itemised and properly seperated for you, if you are in doubt get a breakdown then take it to the Citizens advice to make sure you fully understand exactly how much you're expected to pay for what. ???
