Savings in an ISA
You can save up to £20,000 a year in ISAs and the interest is tax-free. £5,000 fits within the yearly ISA allowance, so all of the interest could be tax-free.
Why the interest rate matters more than it looks
Over ten years at 4% with interest added each year, £5,000 grows to about £7,401, against £6,095 at 2%. Inflation reduces what the money can buy, so a rate below inflation loses value in real terms.
