Calculate the Net Price, the Sales Tax or the Total Price

By entering a number in one of the fields (Net - Tax - Total), this calculator automatically fills in the empty boxes. For example, if you want to calculate the net price and the sales tax from a total amount of $90 with a 20% rate, just enter 90 in the "Total" box, and the application reveals the net amount, which is $75, as well as the tax amount, which equals $15.

You will find another example in the image below.

In this example, we want to convert a total of 4500 into its net price. The result, as shown, is 3750.

Sales tax: calculate and reverse

This calculator can perform the reverse sales tax calculation. So every user can find the amounts associated with a given tax amount.

Sales tax rates

In the United States, sales tax rates vary by state and even by city or county: the combined rate is usually between 0% and about 10%. For example, the base state rate is 7.25% in California and 4% in New York State, while the combined rate reaches 8.875% in New York City. Some states, such as Oregon and Delaware, have no sales tax at all.

Rate not in the list?

For specific rates, select "Other" and enter the desired rate.

With this feature, you can use any percentage for the tax calculation — including VAT rates from other countries.

Net field

The Net field is the total before tax.

Total field

The Total field is the amount including all taxes.

Approximate result

In some cases, entering an amount in the Total field can lead to a slight difference of about $0.01. This means the total recalculated from the obtained net price may differ by 1 cent from the initial amount.

For example, if we look for the net price of a total of $2,584.83 with a 2.1% rate, the result is $2,531.67. But if we redo the calculation the other way, we get a total of $2,584.84. So there is a one-cent difference between the entered total and the recalculated total.

What is sales tax?

Sales tax is an indirect consumption tax added to the price of goods and services, paid only by consumers. Businesses collect this tax and remit it to the state and local authorities. In many other countries, the equivalent is the VAT (value-added tax) — this calculator works for both.
