How to calculate the amount of sales tax?

1.      Convert tax percentage into a decimal by moving the decimal point two spaces to the left.
2.      Multiple the pre-tax value by the newly calculated decimal value in order to find the cost of the sales tax.
3.      Add the sales tax value to the pre-tax value to calculate the total cost.

Calculating sales tax at time of purchase:

In order to calculate the sales tax of an item, we need to first multiply the pre-tax cost of the item by the sales tax percentage after it has been converted into a decimal. Once the sales tax has been calculated it needs to be added to the pre-tax value in order to find the total cost of the item. Let's start by working with an example. If a magazine costs $2.35 and has a 6% sales tax, then what is the total cost of the item. First, we need to convert the sales tax percentage into a decimal by moving the point two spaces to the left.

Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.

Round to two decimal places since our total is in dollars and cents.

Last, add this value to the pre-tax value of the item to find the total cost.

Calculating the sales tax percentage of a total:

If we are given the total cost of an item or group of items and the pre-tax cost of the good(s), then we can calculate the sales tax percentage of the total cost. First, we need to subtract the pre-tax value from the total cost of the purchase. Next, we need to create a ratio of the sales tax to the pre-tax cost off the items. Last, we need to create a proportion where the pre-tax cost is related to 100% and solve for the percentage of the sales tax. Let's start by working through an example. If a person pays $245.64 for groceries that cost $220.00 pre tax, then what is the sales tax percentage for the items.

First, subtract the pre-tax value from the total cost of the items to find the sales tax cost.

Next, create a ratio of the sales tax to the pre-tax cost of the items.

Last, create a proportion where the pre-tax value is proportional to 100% and solve for the percentage of sales tax.

Cross multiply and solve.

Isolate the sales tax percentage to the left side of the equation by dividing each side by the pre-tax value.

Round to two decimal places since our answer is in dollars and cents.

Last, we can check this answer by calculating the sales tax percentage of the total as seen previously.

First, we need to convert the sales tax percentage into a decimal by moving the point two spaces to the left.

Now, we need to multiply the pre-tax cost of this item by this value in order to calculate the sales tax cost.

There are two ways to do this.  The easiest way is to realize that the total cost is 107.5% of the price of the shirt.  This is like saying, "What is 107.5% of 44?"  

This can be rewritten as an equation:

You can also calculate the taxes first by taking 7.5% of 44:

Add this to 44 to get a total cost of $47.30.

Solution: 

There are two ways that you could set up this problem.  For the first way, you would ask yourself, "$76.96 is 104% of what original price?"  This would be represented as:

Likewise, you could start by asking yourself, "A 4% increase of what price ends up at $76.96?" This would be translated as:

Note that this is the same as the equation above.

Solve the first equation by dividing both sides by 1.04.  This gives you $74.

Solution: 

The easiest way to solve this problem is by realizing that you can apply an 8% tax to an amount by multiplying that amount by 108% or 1.08.  You could thus say to yourself, "$59.40 is 108% of what original amount?"  This can be rewritten as the following equation:

Dividing both sides by 1.08, you get .

Now, be careful!  The question asks NOT for the original price but for the tax amount, or .
