1. What is Sales Tax?

Sales tax is a consumption tax imposed by the government on the sale of goods and services. It is typically calculated as a percentage of the purchase price and added to the final cost paid by the consumer.

2. How Does the Calculator Work?

The calculator uses the sales tax formula:

Where:

• \( Sale Amount \) — The original price of goods or services (in currency)
• \( Tax Rate \) — The applicable tax rate expressed as a decimal (e.g., 0.08 for 8%)
• \( Tax \) — The calculated tax amount (in currency)

Explanation: The formula multiplies the sale amount by the tax rate to determine the tax amount that will be added to the purchase.

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is essential for businesses to comply with tax regulations, maintain proper financial records, and provide customers with correct pricing information. It helps prevent underpayment or overpayment of taxes.

4. Using the Calculator

Tips: Enter the sale amount in your local currency and the tax rate as a decimal value (e.g., 0.075 for 7.5%). All values must be valid (sale amount > 0, tax rate between 0 and 1).
