UK Savings Interest Calculator — Personal Savings Allowance & Starting Rate
Free UK savings interest tax calculator. Estimate tax on savings using the Personal Savings Allowance (PSA) and Starting Rate for Savings. See how much interest is tax-free.
The Personal Savings Allowance (PSA) lets basic rate taxpayers earn £1,000 of savings interest tax-free, higher rate taxpayers £500, and additional rate taxpayers £0. The Starting Rate for Savings provides a 0% tax rate on up to £5,000 of savings income, reduced by £1 for every £1 of non-savings income above the Personal Allowance. Most banks deduct 20% tax from interest automatically, so basic rate taxpayers don't need to do anything extra.
