An example:

Annual Zone 3-5 £776
Annual Zone 3-6 £928

Difference £152
The price of the new ticket is £2.54 x 184 days, which is £467.36.

Therefore, the additional amount to be paid for the changeover is
£467.36 - £391.92, which is £75.44.

I think it's weird that your figure is so close to ½ of the previous
one.

Actually, if you look at my original post, I quoted £76 for the extra
to be paid, it is in the paragraph after the 'Difference £152' (6
months being 50% of the twelve months validity for the annual. I only
did a quick and nasty calculation, not taking into account that months
have different numbers of days, hence 184 days in Barry's calculation,
compared to 6months in mine and that you are surrendering the old
ticket and using the value towards the cost of buying the new).

So Barry's more correct working saves the punter 56p In the case of
LUL, I was told that any ticket office can do the upgrade.
