1. What is Sales Tax?

Sales tax is a consumption tax imposed by the government on the sale of goods and services. In the UK, this is known as Value Added Tax (VAT), which is currently set at 20% for most goods and services.

2. How Does the Calculator Work?

The calculator uses the sales tax formula:

Where:

• \( Sale\ Price \) — The original price of the item before tax (GBP)
• \( Tax\ Rate \) — The applicable tax rate as a decimal (e.g., 0.20 for 20%)
• \( Tax\ Amount \) — The calculated tax amount (GBP)

Explanation: The formula multiplies the sale price by the tax rate to determine the tax amount, which is then added to the sale price to get the total price.

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is crucial for businesses to comply with tax regulations, maintain proper financial records, and provide customers with correct pricing information.

4. Using the Calculator

Tips: Enter the sale price in GBP and the tax rate as a decimal (e.g., 0.20 for 20% VAT). All values must be valid (sale price > 0, tax rate between 0-1).
