New share capital gains calculator site ukcgt.xyz is born!

Yesterday, I quickly created a new website at ukcgt.xyz. Since .co.uk and .com were already taken, I went with the .xyz domain as easy2boot.xyz uses it and it was the cheapest!

The new Hostinger site uses the same code as the ukcg page on the easy2boot.xyz site. I will put a link on the easy2boot.xyz page to point users to the new site soon.

Trading 212 and Interactive Investor .csv files have been well tested. I have also tested one Barclays .csv which seems to work OK. The cgtcalculator.com format and a few others are also supported (you can paste the text in or load is from a .txt file).

The new UKCGT site has a Forum, so please feel free to ask question or report issues.

If you want support added for a broker format, I must send me an example .csv file of a real UK-based account. You can mangle any ID numbers if you wish and reduce the rows, but any heading lines at the start should not be omitted or changed (I would prefer a freshly dowloaded file - preferable one with an example of different types of orders and some splits).





Simplest format for data entry

You can type or paste in a simple format such as the one below, with just the number of shares (qty) and price per share in £ if you wish.

B  01/03/2018   SWDA                 1000         3.6093        
B  28/08/2018   SWDA                 1000         4.1565     
S  28/11/2019   SWDA                 2000         4.6702      
B  05/12/2019   SWDA                  500         4.7012         
B  12/02/2020   EQQQ                  150         210.45         
B  18/03/2021   EQQQ                  100          247.8        
S  04/04/2021   EQQQ                  120          305.6         
B  10/06/2021   EQQQ                   50          299.2       
S  15/03/2022   EQQQ                   80          318.4   

Two extra columns for fees and tax will be added as zero when you click Calculate. The Price per share you use should be the Net price - e.g.  (total cost + tax + fees / no. of shares) = net price.

Other calculators

I have given links to some other calculators if you want to compare results.
