1. What Is Sales Tax Rate Calculation?

Sales tax rate calculation determines the percentage of tax applied to a purchase by analyzing the relationship between the tax amount and the pre-tax price. This is essential for financial analysis, accounting, and understanding tax implications.

2. How Does The Calculator Work?

\[ \text{Tax Rate} = \left( \frac{\text{Tax Amount}}{\text{Pre-Tax Amount}} \right) \times 100 \]

Where:

$ \text{Tax Amount} $ — The amount of tax paid in dollars ($)
$ \text{Pre-Tax Amount} $ — The original price before tax in dollars ($)
