Just seen an ad in the paper for TSB, 1.70% AER on fixed term 2 year ISA, in plain speak what does this mean for say a £10,000 investment, what return? Currently with Santander who upped my ISA to 1.50%.
£10000 after 1 year will be £10170
After 2 years it will be £10343.
The Santander figure is £10302
So, even if the actual calculation is slightly different (eg may be no interest for first few days), it's going to be near enough £40 more than with Santander
