Hi,

Last year I place £24,200 in to nationwides online cash isa. Through out the year I added the total amount for my allowance which was £5,340. The intrest rate on this account was 3.10% that inclued a bonus rate which I think should have lasted a full 12 months.

I had my statment though and I only recived £331.31 instrest. From using a instrest calculater and just using my inital investment of £24,200 the tax free instrest on a rate of 3.1% is about £750. Have nationwide made a mistake? or am I just working this out incorrecty?

Thanks

Joe.
