About This Calculator
This sales tax calculator helps you quickly determine the sales tax amount and total (gross) price for any purchase. Enter the net price (pre-tax amount) and the applicable sales tax rate to see how much tax you are paying and the final cost.
The calculation is straightforward: Tax Amount = Net Price x (Tax Rate / 100) and Total Price = Net Price + Tax Amount. The calculator supports reverse calculations -- if you know the total price and need to find the tax rate, simply adjust the inputs until the net price matches.
Sales tax is a consumption-based tax applied at the point of final sale. It is widely used across the United States at state and local levels, with rates varying from 0% to over 10% depending on the jurisdiction. Unlike VAT (common in Europe, India, and other regions), sales tax is collected only once from the end consumer by the retailer.

Frequently Asked Questions
How do I calculate sales tax from the net price?
Multiply the net price by the sales tax rate divided by 100. For example, if the net price is $100 and the sales tax rate is 8%, the tax amount is $100 x 0.08 = $8.00. The total price (gross) is $100 + $8 = $108.00.
What is the difference between sales tax and VAT?
Sales tax is a single-stage tax applied only at the point of final sale to the consumer. VAT (Value-Added Tax) is a multi-stage tax applied at every step of the production and distribution chain. Both ultimately burden the consumer, but VAT allows businesses to reclaim tax paid on inputs.
Which US states have no sales tax?
Five US states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska and Montana allow local jurisdictions to impose their own sales taxes.
How do I calculate the sales tax rate from the total?
To reverse-calculate the sales tax rate, subtract the net price from the gross price to get the tax amount. Then divide the tax amount by the net price and multiply by 100. For example, if gross is $108 and net is $100, the rate is ($8 / $100) x 100 = 8%.
Is sales tax the same across all states in the US?
No, sales tax rates vary significantly by state. Combined state and local rates range from 0% in Delaware, Montana, New Hampshire, and Oregon to over 10% in Louisiana and Tennessee. Local jurisdictions can add their own sales tax on top of the state rate.
Do I charge sales tax for out-of-state customers?
In most cases, you do not charge sales tax for out-of-state orders unless you have a physical presence (nexus) in the buyer's state. However, many states now have economic nexus laws requiring out-of-state sellers to collect tax once they exceed a certain sales threshold.
What is the sales tax rate in India?
India does not have a federal sales tax. Instead, it uses a Goods and Services Tax (GST) system with rates of 0%, 5%, 12%, 18%, and 28%. Some items like alcohol and petroleum are taxed separately by state governments.
