To figure out the sales tax on a calculator, you need to follow a few simple steps. Let’s say you have a product with a net price of $45. The first thing you need to do is calculate the tax amount. To do this, multiply the net price by the tax rate, which in this case is 4%.
Using a calculator, you can easily perform this calculation. Enter the net price of $45, followed by the multiplication symbol (*), and then enter the tax rate as a decimal, which is 0.04. Press the equals (=) button, and the calculator will give you the tax amount. In this case, the tax amount would be $1.8.
Once you have calculated the tax amount, you need to find the gross price, which is the net price plus the tax amount. To do this, add the tax amount to the net price. Using the same example, the gross price would be $45 + $1.8 = $46.8.
In summary, to figure out the sales tax on a calculator, you need to multiply the net price by the tax rate to find the tax amount, and then add the tax amount to the net price to find the gross price. It’s a simple calculation that can be easily done on a calculator.
