What is Sales Tax?
Sales tax is a consumption tax imposed by governments on the sale of goods and services. The tax is typically calculated as a percentage of the purchase price and added at the point of sale. Sales tax rates vary by:
- Country: Different nations have different tax systems
- State/Province: Many countries allow regional variations
- City/Local: Some municipalities add additional taxes
- Product Type: Certain items may have different tax rates
How to Use the Sales Tax Calculator
Our calculator can compute any one of these three values when you provide the other two:
- Before-tax price: The original price of the item before tax
- Sales tax rate: The percentage tax rate applied
- After-tax price: The final price including tax
Example Calculations
Calculating Final Price
If an item costs $100 before tax and the sales tax rate is 7%:
Final Price = $100 + ($100 × 0.07) = $107
Calculating Original Price
If the final price is €120 including 20% tax:
Original Price = €120 ÷ 1.20 = €100
Calculating Tax Rate
If an item costs ₹500 before tax and ₹550 after tax:
Tax Rate = (₹550 – ₹500) ÷ ₹500 × 100 = 10%
