Savings in an ISA

You can save up to £20,000 a year in ISAs and the interest is tax-free. You have more than the yearly ISA limit, so part of £50,000 would need to go in a normal savings account, or be moved into an ISA over several tax years.

Why the interest rate matters more than it looks

Over ten years at 4% with interest added each year, £50,000 grows to about £74,012, against £60,950 at 2%. Inflation reduces what the money can buy, so a rate below inflation loses value in real terms.
