The Tax on Savings Interest Calculator helps UK taxpayers estimate the amount of tax they need to pay on their savings interest income for the 2023-24 tax year. It uses the standard tax calculation formula based on your interest income and applicable tax rate.
The calculator uses the tax calculation formula:

Explanation: The calculator multiplies your total interest income by your tax rate (converted to decimal) to determine the tax liability.
Details: Accurate tax calculation on savings interest is crucial for compliance with UK tax laws, avoiding underpayment penalties, and effective financial planning. Different tax bands may apply based on your total income.
Tips: Enter your total interest income in pounds sterling and your applicable tax rate as a percentage. Ensure both values are positive numbers, with the tax rate between 0-100%.
