Tax on your interest
At 4%, £10,000 earns £400.00 a year. That is within the £1,000 allowance for a basic-rate taxpayer, so no tax would be due.
Basic-rate taxpayers can earn up to £1,000 of savings interest tax-free (the Personal Savings Allowance), higher-rate taxpayers £500 and additional-rate taxpayers none. People with low other income may also have a starting rate for savings band of up to £5,000. Interest in an ISA is always tax-free.
What if you add a little every month?
Adding £100 a month to £10,000 at 4% would take the pot to about £18,784 after five years, compared with £12,167 with no top-ups. You would have paid in £16,000 of that.
How to get a better rate
- Compare easy-access, notice and fixed-rate accounts: fixed accounts usually pay more but lock the money away.
- Check whether the headline rate is a short-term bonus that drops after a year.
- Switch when your rate falls: banks often cut rates on old accounts.
- Use your ISA allowance each year so that interest stays tax-free.
- Keep an emergency fund of three to six months of spending in an instant-access account.
