1. What is the Savings Interest Tax Calculator?

The Savings Interest Tax Calculator estimates the tax payable on savings interest based on UK tax brackets. It helps individuals understand their tax liability on interest earned from savings accounts and investments.

2. How Does the Calculator Work?

The calculator uses the simple tax formula:

Where:

• \( I \) — Interest earned (GBP)
• \( \text{Tax Rate} \) — Applicable tax rate (%) based on income bracket

Explanation: The calculation multiplies the interest earned by the applicable tax rate percentage to determine the tax amount payable.

3. Importance of Tax Calculation

Details: Accurate tax calculation on savings interest is crucial for proper financial planning, tax compliance, and avoiding underpayment penalties from HMRC.

4. Using the Calculator

Tips: Enter the total interest earned in GBP and the applicable tax rate percentage based on your income tax bracket. All values must be valid (interest ≥ 0, tax rate between 0-100%).
