Sales Tax Calculator

Instantly calculate sales tax, total price, or price before tax. Perfect for shoppers, businesses, and anyone needing quick, accurate tax breakdowns.

Understanding Sales Tax

Sales tax is a consumption tax imposed by governments on the sale of goods and services. It is typically collected at the point of sale and remitted to tax authorities by businesses. The rate and rules vary by country, state, and even city, making it important for both consumers and businesses to understand how it works. Some states in the U.S. have no sales tax, while others have combined state and local rates that can exceed 10%.

There are different types of sales taxes, including state, local, use, and excise taxes. Businesses must comply with the correct rates and regulations for their location, and consumers should be aware of how much tax they are paying on purchases. This knowledge is crucial for budgeting, pricing, and tax compliance.

How This Tool Works

The Sales Tax Calculator allows you to quickly determine the tax amount, total price including tax, or the price before tax. Simply enter the price and the tax rate, then choose whether you want to add tax to a base price or remove tax from a total price. The tool instantly calculates and displays the results, making it easy to understand the breakdown of your purchase or sale.

The calculator uses precise mathematical formulas to ensure accuracy. For adding tax: Tax Amount = Base Price × Tax Rate, Total Price = Base Price + Tax Amount. For removing tax: Base Price = Total Price ÷ (1 + Tax Rate), Tax Amount = Total Price - Base Price.
