Natwest ISA interest rates 2008

autolycus

I am trying to check the Natwest Cash ISA interest rates and the dates of any changes from November 2008 to March 2009. I can only find the rates from April onwards on the Natwest web site, and I am not confident of the accuracy of any answers I might get by phoning my branch.

Does anyone have any references, please, or even information from their own notes?

Thanks

Nope, but if you have any questions about the calculation I might be able to help (because I kept a beady eye on them too). 2% bonus started at 7.32 from memory.

If you calculate monthly interest then be aware it will be the GROSS figure and not the AER. The AER is acheived once it's all compounded.

Nat West months are variable, so sometimes it's 27 days and other times 32, doesn't appear to be very consistent, so if you calculate interest you need to calculate the correct number of days e.g.
capital at start of month * gross rate * number of days / 365

Having said that I haev always found our two accounts to be correct.
