What is Sales Tax

Sales tax is a direct tax collected by the government, local or national, for the sales of goods and services.

Calculations

To calculate the total sales tax, devide the sales tax by 100 (to get the percentage) and multiply it to the item price. To get the total price, add the total sales tax to the price.

Formulas

Total Sales Tax:

st = p * (t / 100)

Where:
st = total sales tax
p = price of the item
t = sales tax
            
Total Price:

tp = p + s

Where:
tp = total price including sales tax
p = price of the item
s = total sales tax
