1. What is Sales Tax Rate?

The sales tax rate is the percentage of tax applied to a purchase. It's calculated by dividing the tax amount by the purchase amount before tax. Understanding this rate helps consumers and businesses budget accurately.

2. How Does the Calculator Work?

The calculator uses the sales tax rate formula:

Where:

• \( \text{Tax} \) — Amount of tax paid (in currency)
• \( \text{Amount} \) — Purchase amount before tax (in currency)

Explanation: The formula shows the proportion of tax relative to the purchase price, expressed as a decimal. Multiply by 100 to get the percentage.

3. Importance of Sales Tax Calculation

Details: Knowing the sales tax rate helps with financial planning, comparing prices across regions with different tax rates, and ensuring proper tax collection for businesses.

4. Using the Calculator

Tips: Enter the tax amount and purchase amount in dollars (or your local currency). Both values must be positive numbers, and the purchase amount cannot be zero.
