Interest paid - what does it mean?

Ummm.... the day of the month that the end date of the loan falls on.  If the loan ends on the 23rd of a month, interest payments are paid on the 23rd of each month. 28, 29, 30 and 31 might be slightlty problematical, but rare. Any calculations you wish to make in a spreadsheet have to take place backwards from that end date, so to speak.

I suspect that that I am not the only one to use a word search in my spreadsheet to separate out interest, cashback and other payment types.

When updating my spreadsheets yesterday I noted that some of the terminology on the download has changed, so for example

Residential xxxxxxx - xxxxxxx (BPF289) monthly repayment (my added xxxxx)
has now become
(BPF289) Residential xxxxxx - xxxxxx interest payment


..... so if your word search was 'monthly repayment' you will not pick up the interest payment.  No big issue if you notice it but if you don't your totals won't tally.

Thought it worth a mention.

I think the change to statement entries after 26 March 2016 is that "monthly repayment" entries have been replaced by two entries: "capital repayment" and "interest payment".  I seem to remember someone asked for the statement to split these two items.

A multitude of reasons.

I like to know how my investments are performing on a continuing basis throughout the year, not just at year end.

I need to know my tax liabilities (I invest as an individual, through my Ltd Co and on behalf of my partner) so I can do a spot of balancing as required.

Taxation of companies is different to individuals some generated tax returns do not cater for this difference.

I invest through a fair number of platforms and have a decent 6 figure sum invested overall - it is easy to become 'platform heavy' if I spot a good loan, invest in that and reinvest all interest payments.

A check on the statement (if supplied) - one platform I invest through doesn't supply a statement so my figures provide the figure used on my returns.
