Calculating the final price of a product in the US can be confusing because sales tax rates vary between states and local jurisdictions.
For a $100 product, the amount you actually pay can be higher after sales tax is added.
To make these calculations easier, I created a free US Sales Tax Calculator with DailyCodeTools.

What Does the Calculator Do?
The calculator can help you quickly estimate:
- Sales tax amount
- Final price after tax
- Pre-tax price from a tax-inclusive amount
- Discounted price
- Taxable shipping or handling charges
- Effective tax rate
- Total out-of-pocket cost
How Is Sales Tax Calculated?
The basic formula is:
Sales Tax = Taxable Amount × Sales Tax Rate
For example, if a product costs $250 and the applicable sales tax rate is 8%:
$250 × 8% = $20
The estimated final price would be:
$250 + $20 = $270
You can enter the amount and tax rate into the calculator instead of doing the calculation manually.
Calculate the Price Before Tax
Sometimes you already know the final price, including sales tax, but want to find the original price.
The basic formula is:
Pre-Tax Price = Final Price ÷ (1 + Tax Rate)
The calculator's Extract Tax mode can make this calculation easier.
Calculate Tax After a Discount
Discounts can change the amount on which tax is calculated.
For example:
Original Price: $500
Discount: $50
Taxable Subtotal: $450
Tax Rate: 8%
Sales Tax: $36
Final Cost: $486
The calculator allows you to include a discount when estimating your total cost.
What About Shipping?
For online purchases, shipping and handling charges can sometimes be relevant to the taxable amount.
The calculator lets you enter shipping or handling fees so you can include them when appropriate.
Keep in mind that the tax treatment of shipping varies by jurisdiction.
Why Are US Sales Tax Rates Different?
The US does not have one single nationwide retail sales tax rate.
Sales tax can involve:
- State taxes
- County taxes
- City taxes
- Special district taxes
As a result, the applicable combined rate can depend on where the transaction is taxed.
For an exact tax obligation, always verify the applicable rate and rules with the relevant tax authority.
Who Can Use This Calculator?
This tool can be useful for:
- Online shoppers
- Small business owners
- Freelancers
- E-commerce sellers
- Developers building pricing tools
