Calculate a purchase tax and tax-inclusive total from a price before tax and one percentage rate.
Tax Breakdown
How Sales Tax Is Calculated
The tax amount is the entered pre-tax purchase amount multiplied by the tax rate expressed as a percentage. The calculator adds that tax to the original amount to show the estimated total. For example, a rate of 6% means 0.06 is applied to the entered price.
Local rules can change the total
The tool applies one flat rate. It does not determine which items are taxable, combine state and local rates, apply exemptions, calculate tax-inclusive prices, or account for special product rules. Check the applicable tax authority or retailer for the correct rate.
Financial note: This is a basic arithmetic estimate, not tax advice or a substitute for official tax guidance.
Example and limitations
The result applies one tax percentage to the entered pre-tax amount. It does not look up local rates, exemptions, tax-on-tax rules, or special product categories.
