TBH , I think BT are one of the better providers when it comes to explaining how the ETC is calculated ..the only variable is the ‘amount BT save by not providing service’ , in the example it’s £15 on a £35 monthly bill , but you may pay more or less than that , but the principal is clear , in the example if £140 is the amount BT would have received if the customer hadn’t quit early and the actual ETC is £67 , that’s around half , so a reasonable guide would be to add up the amount per month you would pay and half it , it won’t be exactly correct but will be in the ballpark
Example of a cancellation fee
- You pay £35 a month and you have four months left in your minimum contract period.
- We multiply £35 by four months, totalling £140.
- We take off VAT, reducing it to £116.67.
- We take off the costs we save, for example, £15 per month, multiplied by 4 = £60, leaving £56.67.
- We discount by 1% for early receipt, making £56.10.
- We add on VAT, making your final early termination fee £67.32.
