What if you add a little each month?

Keeping the risk in proportion
Higher returns come with more risk. A cash account is predictable but may not keep up with prices. Savings and investments held in an ISA are free of UK income tax and capital gains tax. Outside an ISA, interest above your Personal Savings Allowance and gains above the annual exempt amount can be taxed.
