About Sales Tax

Sales tax is a consumption tax imposed by the government on the sale of goods and services. The tax is usually calculated as a percentage of the purchase price.

Tax Exclusive vs Tax Inclusive
  • Tax Exclusive: The tax is added to the purchase price. This is the most common method in the United States.
  • Tax Inclusive: The tax is already included in the displayed price. This method is common in many countries outside the US, like in Europe (VAT).
Formulas Used
  • Tax Exclusive:
    • Tax Amount = Purchase Price × (Tax Rate ÷ 100)
    • Final Price = Purchase Price + Tax Amount
  • Tax Inclusive:
    • Tax Amount = Purchase Price × [Tax Rate ÷ (100 + Tax Rate)]
    • Pre-Tax Price = Purchase Price - Tax Amount
Important Notes
  • Sales tax rates vary by location (state, county, city) and sometimes by product category.
  • Some items may be exempt from sales tax in certain jurisdictions (e.g., groceries, medications).
  • This calculator provides estimates. For exact tax calculations related to your business, consult with a tax professional.

For example, you might see rates like 4%, 6%, or even 9.5%. This feature can save time by allowing you to quickly select a rate without having to look it up each time.

Understanding Tax Amount and Final Price

  • Tax Amount: This is the amount you pay on top of your purchase price based on the tax rate.
  • Final Price: This is the total amount you will pay, which includes the purchase price plus the tax amount.
