Key Insights
Sales tax is a government-imposed charge on goods and services.
Sales tax is a mandatory charge applied when a good or service is sold. The seller is responsible for collecting this tax from the buyer and then remitting it to the government. The collected tax revenue is used by the government to fund public services such as infrastructure development (e.g., roads, water lines) and public education (e.g., paying teachers).
Calculating sales tax involves converting the percentage to a decimal and multiplying by the item's price.
To calculate the final cost of an item including sales tax, you first need to determine the sales tax rate, which varies by location and item, typically ranging from 4% to 9%. This percentage is then converted into a decimal by dividing by 100 (e.g., 8.25% becomes 0.0825). Next, add 1 to this decimal (e.g., 1 + 0.0825 = 1.0825). Finally, multiply the original price of the item by this new number (1.0825 in the example). The result should then be rounded to the nearest hundredth to determine the total cost.

Understanding Sales Tax
Sales tax is a mandatory charge on goods or services.
Sales tax is a type of tax that is applied whenever a good or service is sold. The seller collects this tax from the buyer and then transfers it to the government. Governments use these funds to pay for public services like roads, water lines, and teachers' salaries.
Some US states have no statewide sales tax.
There are five states in the United States that do not impose a state-level sales tax. These states are Delaware, Alaska, Montana, New Hampshire, and Oregon.
Sales tax rates vary and some items are exempt.
The rate of sales tax is calculated as a percentage of the purchase price and varies depending on the state and the specific item being bought. Generally, sales tax rates fall between 4% and 9%. Some items, like groceries and certain prescription medications, may be exempt from sales tax in some locations.
How to Calculate Sales Tax
Frankie's book purchase: initial price and total money available.
Frankie wants to buy a book that costs $5 before sales tax. She has a total of $6 available and wants to ensure she has enough money to cover the book's price plus the sales tax.
Determining the sales tax rate for the book.
After researching, Frankie finds out that the applicable sales tax rate for the book is 8.25%.
Converting the sales tax percentage to a decimal.
The first step in calculating the total cost is to convert the sales tax percentage into a decimal. For an 8.25% sales tax, this is done by dividing by 100, resulting in 0.0825.
Calculating the total cost by multiplying the price by 1 plus the decimal tax rate.
To find the total cost, Frankie multiplies the original sales price of the book ($5) by 1 plus the decimal sales tax rate (1 + 0.0825 = 1.0825). So, the calculation is $5 \times 1.0825 = 5.41125$.
Rounding the total cost to the nearest hundredth.
The calculated total cost of $5.41125 needs to be rounded to the nearest hundredth to represent standard currency. Rounding this number gives a final price of $5.41 for the book.
Confirming Frankie can afford the book.
Since the total cost of the book with sales tax is $5.41, and Frankie has $6, she has enough money to purchase it.
Encouragement to practice calculating sales tax.
