If you are considering investing £20,000.00 in a NatWest Cash ISA, the returns will depend on the specific interest rate and term you choose. As per the latest information available from NatWest, here are the key options for fixed-rate Cash ISAs:

1. One-Year Fixed Rate Cash ISA: This account offers an interest rate of 4.01% AER (Annual Equivalent Rate) tax-free per annum. For a £20,000 investment, at this rate, you would earn approximately £802 in interest over one year.

2. Two-Year Fixed Rate Cash ISA: This account provides a slightly lower rate of 3.86% AER tax-free per annum. With a £20,000 investment at this interest rate, the interest earned over two years would be about £1,544.

It is important to note that both options entail no withdrawals or deposits during the term of the ISA.

You can review these options further on NatWest's official pages. For more details on the Fixed Rate Cash ISA and current offerings, visit NatWest's Fixed Rate Cash ISA page. You can also compare other ISA options on their ISA overview page.
