Using the new BPF calculations announced a couple of days ago an item listed for £27.84 will have BPF added at 7% for the first £20 plus 4% for the remaining £7.84 plus 10p flat-fee - I make that £1.40 + £0.31 + £0.10 = £1.81 and the item total including BPF would be £27.84 + £1.81 = £29.65
On double-checking that I have just noticed that only applies to items listed on or after 17 July 2025; items listed prior to that date would attract a BPF of 4% + 75p flat-fee, which would be £1.11 + £0.75 = £1.86 giving an item total price of £27.84 + £1.86 = £29.70
@siybon Sorry to say that you under the new BPF rates you won't be able to tweak your list price so that shows as £29.95. It's a rounding issue as a result of using split percentages and then adding the flat-fee. It works like this:
You want to list at £29.95 including the BPF. Your start amount therefore needs to be £29.95 - £0.10 = £29.85 minus the % element of BPF. For the first £20 that is 7% (£1.40), giving you £29.85 - £1.40 - £20.00 = £8.45 attracting a BPF rate of 4%, or £0.33, leaving a net amount of £8.45 - £0.33 = £8.12
Your starting price is therefore needs to be £29.95 - £1.40 - £0.33 - £0.10 = £28.12 but working forwards from that gives you £28.12 + £1.40 (7% of £20) + £0.32 (4% of £8.12 - it's actually £0.3248 rounded down) + £0.10 = £29.94.
Changing your start price to £28.13 won't work either because 4% of £8.13 is £0.3252, which would be rounded up to £0.33 and give a final price including BPF of £28.13 + £1.40 + £0.33 + £0.10 = £29.96
Of course all this is using just the latest BPF calculation structure, which has just changed rather significantly even though it was only introduced six months ago. Give it another six months and it will probably change again...
