If you have an account which issues you with a passbook you can easily see the value of your savings as they are entered. Otherwise statements should be sent regularly to you. Generally, the rate of interest you earn varies with the sum you have deposited. It is said to be 'tiered'. As an example, the rates of interest paid on different sums in the National Savings Investment Account are given in Table 4 .
Some accounts pay interest gross, that is, without deduction of income tax.
Others pay the interest net, that is, after deduction of tax at the standard rate. Accounts with interest paid gross may be more attractive to non-taxpayers, as this saves you the bother of claiming back tax later from the Inland Revenue.
